The meaning of the symbols of dreams/ seen in a dream.


An aqueous extract of one or a few herbs ; a common method for preparing tea (té); typically 2 teaspoons of dried plant material (1/4 cup if fresh) in 1 cup of hot (boiling) water, infused for 10-15 minutes; technically, an infusion is not boiled, whereas when making a decoction, the herbs are boiled in water. Most Dominican herbal remedies are prepared as decoctions.... infusion


The ability to resist infection and to heal. The process may involve acquired immunity, (the ability to learn and remember a specific infectious agent), or innate immunity (the genetically programmed system of responses that attack, digest, remove, and initiate inflammation and tissue healing).... immunity


An inflammation of the skin associated with discrete vesicles due to streptococcal infection... impetigo


Inability to perform the sexual act due to failure of the reflex mechanism... impotence


The inability to retain urine in the bladder for a reasonable length of time. It is can be caused by urethral irritation, loss of tone to the basement muscle of the bladder (the trigone), scarification or growths on the urethral lining, nerve damage, or emotional stress.... incontinence


The entry and development or multiplication of an infectious agent in the body of humans or animals. Infection is not synonymous with infectious disease; the result may be inapparent or manifest. The presence of living infectious agents on exterior surfaces of the body, or upon articles or apparel or soiled articles, is not infection but contamination of such surfaces and articles.... infection


Any agent which kills or destroys insects... insecticide


The condition of being unable to sleep... insomnia


An antiviral chemical secreted by an infected cell which strengthens the defence of nearby cells not yet infected.... interferon


See EYE.... iris


Illness, disease, or imbalances created by medical or nonmedical treatment that were not present before treatment. In medicine the therapy is blamed (not the therapist) and changed to something else. In alternative medicine it may be called a “healing crisis” and deemed good for you. Beware: if the therapy makes you feel worse in a new way, it is almost always the wrong therapy.... iatrogenic


No known cause.... idiopathic


The operation by which an arti?cial opening is made into the ILEUM and brought through the abdominal wall to create an arti?cial opening or STOMA. It is most often performed as part of the operation for cancer of the RECTUM, in which the rectum has usually to be removed. An ileostomy is then performed which acts as an arti?cial anus, to which a bag is attached to collect the waste matter. Distressing though this may at ?rst be, the vast majority of people with an ileostomy learn to lead a fully active and normal life. Help and advice in adjusting to what can be described as an ‘ileostomy life’ can be obtained from the Ileostomy and Internal Pouch Support Group.... ileostomy


The lower two-thirds of the small intestine, ending in the ileocecal valve and emptying into the cecum of the colon. The last foot of the ileum is the only absorption site available for such important dietary substances as vitamin Bl2, folic acid, some essential fatty acids, fat soluble vitamins, and recycled bile acids.... ileum

The number of cases of disease, infection or some other event having their onset during a prescribed period of time. It is often expressed as a rate (for example, the incidence of cardiovascular disease per 1000 population aged 65-74 years during a specified year). Incidence is a measure of morbidity or other events that occur within a specified period of time. See also “prevalence”.... incidence

This is diagnosed when a couple has not achieved a pregnancy after one year of regular unprotected sexual intercourse. Around 15–20 per cent of couples have diffculties in conceiving; in half of these cases the male partner is infertile, while the woman is infertile also in half; but in one-third of infertile couples both partners are affected. Couples should be investigated together as e?ciently and quickly as possible to decrease the distress which is invariably associated with the diagnosis of infertility. In about 10–15 per cent of women suffering from infertility, ovulation is disturbed. Mostly they will have either irregular periods or no periods at all (see MENSTRUATION).

Checking a hormone pro?le in the woman’s blood will help in the diagnosis of ovulatory disorders like polycystic ovaries, an early menopause, anorexia or other endocrine illnesses. Ovulation itself is best assessed by ultrasound scan at mid-cycle or by a blood hormone progesterone level in the second half of the cycle.

The FALLOPIAN TUBES may be damaged or blocked in 20–30 per cent of infertile women. This is usually caused by previous pelvic infection or ENDOMETRIOSIS, where menstrual blood is thought to ?ow backwards through the fallopian tubes into the pelvis and seed with cells from the lining of the uterus in the pelvis. This process often leads to scarring of the pelvic tissues; 5–10 per cent of infertility is associated with endometriosis.

To assess the Fallopian tubes adequately a procedure called LAPAROSCOPY is performed. An ENDOSCOPE is inserted through the umbilicus and at the same time a dye is pushed through the tubes to assess their patency. The procedure is performed under a general anaesthetic.

In a few cases the mucus around the cervix may be hostile to the partner’s sperm and therefore prevent fertilisation.

Defective production is responsible for up to a quarter of infertility. It may result from the failure of the testes (see TESTICLE) to descend in early life, from infections of the testes or previous surgery for testicular torsion. The semen is analysed to assess the numbers of sperm and their motility and to check for abnormal forms.

In a few cases the genetic make-up of one partner does not allow the couple ever to achieve a pregnancy naturally.

In about 25 per cent of couples no obvious cause can be found for their infertility.

Treatment Ovulation may be induced with drugs.

In some cases damaged Fallopian tubes may be repaired by tubal surgery. If the tubes are destroyed beyond repair a pregnancy may be achieved with in vitro fertilisation (IVF) – see under ASSISTED CONCEPTION.

Endometriosis may be treated either with drugs or laser therapy, and pregnancy rates after both forms of treatment are between 40–50 per cent, depending on the severity of the disease.

Few options exist for treating male-factor infertility. These are arti?cial insemination by husband or donor and more recently in vitro fertilisation. Drug treatment and surgical repair of VARICOCELE have disappointing results.

Following investigations, between 30 and 40 per cent of infertile couples will achieve a pregnancy usually within two years.

Some infertile men cannot repair any errors in the DNA in their sperm, and it has been found that the same DNA repair problem occurs in malignant cells of some patients with cancer. It is possible that these men’s infertility might be nature’s way of stopping the propagation of genetic defects. With the assisted reproduction technique called intracytoplasmic sperm injection, some men with defective sperm can fertilise an ovum. If a man with such DNA defects fathers a child via this technique, that child could be sterile and might be at increased risk of developing cancer. (See ARTIFICIAL INSEMINATION; ASSISTED CONCEPTION.)... infertility


A specific type of acute viral respiratory infection, with one virus (many strains) and a short, nasty stay. A few thousand people die from it every year, but humans alive at present have almost universal partial resistance. It was not so during WWI, when it first began to spread. It was variously called Spanish Influenza, La Grippe, and Influenza (Italian for Influence)...everyone blamed some other country for it. The Turks and Armenians took a break from mutual mutilation and blamed it on each other, since it was killing as many people as the 1,000,000 fatalities THAT bit of genocide fostered. It ran across the world like some Bergmanesque horseman, and killed at least 20 million people before it petered out around 1925. The villages of Northern New Mexico, filled with grim and genetically toughened Spanish settlers, survivors of terrible weather, 300 years of isolation, the Inquisition and Anglo carpetbaggers, suffered fatalities that reached 40% in some places. The flu is new.... influenza

Intermittent Claudication

A condition occurring in middle-aged and elderly people, which is characterised by pain in the legs after walking a certain distance. The pain is relieved by resting for a short time. It is due to arteriosclerosis (see ARTERIES, DISEASES OF) of the arteries to the leg, which results in inadequate blood supply to the muscles. Drugs usually have little e?ect in easing the pain, but useful preventive measures are to stop smoking, reduce weight (if overweight), and to take as much exercise as possible within the limits imposed by the pain.... intermittent claudication


In?ammation between two skin surfaces in contact, typically in the toe clefts, axillae, under the breasts or in the anogenital folds. Heat, friction and obesity are aggravating factors. Secondary fungal or bacterial infection with CANDIDA or bacteria is common.

Interventional Radiology

The use of radiology (see X-RAYS) to enable doctors to carry out diagnostic or treatment procedures under direct radiological vision. This X-ray procedure is used in MINIMALLY INVASIVE SURGERY (MIS) – for example, ANGIOPLASTY, the removal of stones from the kidney (see KIDNEYS, DISEASES OF), and the observation of obstructions in the bile ducts (percutaneous CHOLANGIOGRAPHY). (See also magnetic resonance imaging – MRI.)... intertrigo

Intrinsic Factor

One of two proteins secreted from the lining of the stomach whose sole purpose is (it seems) to cradle B12 in a pre-fitted styrofoam mold and (A) carry it through the Seven Levels of Digestive Hell until it reaches those few absorption sites in the last foot of small intestine that understand its “Special Needs” (sounds either sexually kinky or the airplane dinner label on kosher food for flying Hassidim jewelers) and finally (B) slip it from one protein to the other, and thence into the cell membranes where its is turn handed over to (C) the specialized blood protein that can carry it safely to the final target tissues (3 times out of 4, the bone marrow). Cyanocobalamin (B12) has parts that fall off, radicals that twirl around in five directions on three charge potentials, and is as durable as a 49¢ water pistol. And, if we have an ulcer, chronic enteritis or long-standing steatorrhea, we either get B12 shots (and hope the liver still makes that blood carrier) or walk around with pernicious anemia and a hematocrit of 16.... intrinsic factor


A non-metallic element which is found largely in seaweed. The body contains about 30 mg, largely concentrated in the THYROID GLAND where it is used to synthesise thyroid hormones. Iodine has a highly irritating action and, when applied to the skin, stains the latter dark brown and causes it to peel o? in ?akes, while internally it is a violent irritant poison in large doses.

Externally iodine is used as an antiseptic. Its drawback is that it is ?xed by protein, which reduces its antiseptic e?ciency in open wounds. Its main use in this sphere therefore is for sterilising the unbroken skin, as before an operation. Radioactive iodine is used for diagnosing and treating disease of the thyroid gland.... iodine


See UVEITIS.... iritis


Lack of tissue oxygen and nutrients usually due to impaired (arterial) blood flow.... ischaemia


A metal which is an essential constituent of the red blood corpuscles, where it is present in the form of HAEMOGLOBIN. It is also present in muscle as MYOGLOBIN, and in certain respiratory pigments which are essential to the life of many tissues in the body. Iron is absorbed principally in the upper part of the small intestine. It is then stored: mainly in the liver; to a lesser extent in the spleen and kidneys, where it is available, when required, for use in the bone marrow to form the haemoglobin in red blood corpuscles. The daily iron requirement of an adult is 15–20 milligrams. This requirement is increased during pregnancy.

Uses The main use of iron is in the treatment of iron-de?ciency anaemias (See ANAEMIA.) Iron preparations sometimes cause irritation of the gastrointestinal tract, and should therefore always be taken after meals. They sometimes produce a tendency towards constipation. Whenever possible, iron preparations should be given by mouth; if PARENTERAL administration is clinically necessary because of malabsorption, a suitable preparation is iron sorbitol injection given intramuscularly. Most patients respond successfully to oral iron preparations.... iron


The separation, for the period of communicability, of infected persons or animals from others, in such places and under such conditions as will prevent the direct or indirect conveyance of the infectious agent from those infected to those who are susceptible or who may spread the agent to others. Can also be used in relation to microorganisms (e.g. a bacterial species isolated from the patient).... isolation

Body Mass Index

Body Mass Index (BMI) provides objective criteria of size to enable an estimation to be made of an individual’s level or risk of morbidity and mortality. The BMI, which is derived from the extensive data held by life-insurance companies, is calculated by dividing a person’s weight by the square of his or her height (kilograms/ metres2). Acceptable BMIs range from 20 to 25 and any ?gure above 30 characterises obesity. The Index may be used (with some modi?cation) to assess children and adolescents. (See OBESITY.)... body mass index

Diabetes Insipidus

Diabetes insipidus is a relatively rare condition and must be di?erentiated from DIABETES MELLITUS which is an entirely di?erent disease.

It is characterised by excessive thirst and the passing of large volumes of urine which have a low speci?c gravity and contain no abnormal constituents. It is either due to a lack of the antidiuretic hormone normally produced by the HYPOTHALAMUS and stored in the posterior PITUITARY GLAND, or to a defect in the renal tubules which prevents them from responding to the antidiuretic hormone VASOPRESSIN. When the disorder is due to vasopressin insu?ciency, a primary or secondary tumour in the area of the pituitary stalk is responsible for one-third of cases. In another one-third of cases there is no apparent cause, and such IDIOPATHIC cases are sometimes familial. A further one-third of cases result from a variety of lesions including trauma, basal MENINGITIS and granulomatous lesions in the pituitary-stalk area. When the renal tubules fail to respond to vasopressin this is usually because of a genetic defect transmitted as a sex-linked recessive characteristic, and the disease is called nephrogenic diabetes insipidus. Metabolic abnormalities such as HYPERCALCAEMIA and potassium depletion render the renal tubule less sensitive to vasopressin, and certain drugs such as lithium and tetracycline may have a similar e?ect.

If the disease is due to a de?ciency of vasopressin, treatment should be with the analogue of vasopressin called desmopressin which is more potent than the natural hormone and has less pressor activity. It also has the advantage in that it is absorbed from the nasal mucosa and so does not need to be injected.

Nephrogenic diabetes insipidus cannot be treated with desmopressin. The urine volume can, however, usually be reduced by half by a thiazide diuretic (see THIAZIDES).... diabetes insipidus

Eye Injuries

Victims of eye injuries are advised to seek prompt medical advice if the injury is at all serious or does not resolve with simple ?rst-aid measures – for example, by washing out a foreign body using an eye bath.

Blunt injuries These may cause haemorrhage inside the eye, cataract, retinal detachment or even rupture of the eye (see also EYE, DISORDERS OF). Injuries from large blunt objects – for example, a squash ball – may also cause a ‘blow-out fracture’ of the orbital ?oor resulting in double vision. Surgical treatment may be required depending on the patient’s speci?c problems.

Chemical burns Most chemical splashes cause conjunctivitis and super?cial keratitis in the victim (see EYE, DISORDERS OF); both conditions are self-limiting. Alkalis are, however, more likely to penetrate deeper into the eye and cause permanent damage, particularly to the cornea. Prompt irrigation is important. Further treatment may involve testing the pH of the tears, topical antibiotics and CORTICOSTEROIDS, and vitamin C (drops or tablets – see APPENDIX 5: VITAMINS), depending on the nature of the injury.

Corneal abrasion Loss of corneal epithelium (outermost layer). Almost any sort of injury to the eye may cause this. The affected eye is usually very painful. In the absence of other problems, the epithelium heals rapidly: small defects may close within 24 hours. Treatment conventionally consists of antibiotic ointment and sometimes a pad over the injured eye.

Foreign bodies Most foreign bodies which hit the eye are small and are found in the conjunctival sac or on the cornea; most are super?cial and can be easily removed. A few foreign bodies penetrate deeper and may cause infection, cataract, retinal detachment or haemorrhage within the eye. The foreign body is usually removed and the damage repaired; nevertheless the victim’s sight may have been permanently damaged. Particularly dangerous activities include hammering or chiselling on metal or stone; people carrying out these activities (and others, such as hedge-cutting and grass-strimming) should wear protective goggles.... eye injuries

Food Intolerance

This is divided into food aversion, where a person simply avoids a food they dislike; food intolerance, where taking the food causes symptoms; and food allergy, where the symptoms are due to an immunological reaction. Some cases of food intolerance are due to idiosyncrasy – that is, a genetic defect in the patient, such as alactasia, where the intestine lacks the enzyme that digests milk sugar, with the result that individuals so affected develop diarrhoea when they drink milk. Intolerance to speci?c foods, as distinct from allergy, is probably quite common and may be an important factor in the aetiology of the IRRITABLE BOWEL SYNDROME (IBS).

For the diagnosis of true food allergy, it is necessary to demonstrate that there is a reproducible intolerance to a speci?c food; also, that there is evidence of an abnormal immunological reaction to it. Occasionally the allergic response may not be to the food itself but to food contaminants such as penicillin, or to food additives such as tartrazine. There may also be reactions to foods which have pharmacological effects, such as ca?eine in strong co?ee or histamine in fermented cheese, or such reactions may be due to the irritant e?ect on the intestinal mucosa (especially if it is already diseased) by, say, highly spiced curries.

Testing blood and skin for food allergy is beloved of some alternative practitioners but, in practice, the results of tests do not necessarily agree with what happens when the food is taken. Therefore, a careful history is as useful as any test in making a diagnosis.... food intolerance

Head Injury

Any injury to the head, whether associated with a skull fracture (see BONE, DISORDERS OF – Bone fractures) or not. Patients with head injuries should be assessed for signs of neurological damage, which may not develop at once. Patients who after a head injury are or have been UNCONSCIOUS or who are drowsy, vomiting, confused or have any focal neurological signs – for example, blurred vision or a motor or sensory malfunction – should be seen by a doctor. Particular care should be taken with individuals who have consumed alcohol and sustained a head injury in a ?ght, fall or vehicle accident. Symptoms indicative of a severe head injury may be attributed (wrongly) to the effects of alcohol, and crucial time thus lost in treating the injury.

In hospital the possible need for urgent action is monitored by use of the GLASGOW COMA SCALE.

People suffering the results of such injuries and their relatives can obtain help and advice from Headway – the brain injury association.... head injury

Iceland Moss

Cetraria islandica

Description: This moss grows only a few inches high. Its color may be gray, white, or even reddish.

Habitat and Distribution: Look for it in open areas. It is found only in the arctic.

Edible Parts: All parts of the Iceland moss are edible. During the winter or dry season, it is dry and crunchy but softens when soaked. Boil the moss to remove the bitterness. After boiling, eat by itself or add to milk or grains as a thickening agent. Dried plants store well.... iceland moss


Jaundice... icterus


A disorder in which the skin is permanently dry and scaly. It is usually genetically determined and several di?erent forms are recognised:

Ichthyosis vulgaris Common and inherited as a dominant trait. Beginning in early childhood, it is often associated with atopic eczema (see DERMATITIS). The limb ?exures and face are spared.

X-linked ichthyosis is much less common, more severe and appears earlier than ichthyosis vulgaris. The ?sh-like scales are larger and darker and do not spare the ?exures and face.

Ichthyosiform erythroderma Of two types and very rare: in the recessive form, the appearance at birth is of the so-called ‘collodion baby’; in the dominant form the baby is born with universally red, moist and eroded skin with an unpleasant smell. Gradually, over several months, thick scales replace the ERYTHEMA.

Treatment Minor forms are helped by constant use of EMOLLIENTS and moisturising applications. Cream containing UREA can be valuable. The rare erythrodermic patterns in the neonate require skilled intensive care as thermoregulation is disturbed and massive ?uid loss occurs through the skin. Later in childhood, oral RETINOIDS are useful.... ichthyosis

A person’s own perceptions, experience and evaluation of a disease or condition, or how he or she feels. For example, an individual may feel pain, discomfort, weakness, depression or anxiety, but a disease may or may not be present.... illness

Immersion Foot

The term applied to a condition which develops as a result of prolonged immersion of the feet in cold or cool water. It was a condition commonly seen during World War II in shipwrecked sailors and airmen who had crashed into the sea, spending long periods there before being rescued. Such prolonged exposure results in VASOCONSTRICTION of the smaller arteries in the feet, leading to coldness and blueness and ?nally, in severe cases, to ulceration and GANGRENE. (See also TRENCH FOOT.)... immersion foot


Procedures which measure the concentration of any antigenic material (see ANTIGEN) to which an antibody (see ANTIBODIES) can be created. The amount of antigen bound to this antibody is proportional to the parent substance. Enzymes (see ENZYME-LINKED IMMUNOSORBENT ASSAY (ELISA)) or radioactive labels (RADIOIMMUNOASSAY) are used to measure the concentration of antigenic material.... immunoassay


The study of immune responses to the environment. Its main clinical applications include improving resistance to microbial infections (see IMMUNITY), combating the effects of impaired immunity (see IMMUNODEFICIENCY), controlling harmful immune reactions (see ALLERGY), and manipulating immune responses (see IMMUNOTHERAPY) to prevent harmful immunological responses such as graft rejection and autoimmune diseases (see AUTOIMMUNITY). The clinical study of disordered immunity now forms the allied discipline of clinical immunology, which is closely linked to the laboratory-based discipline of immunopathology.... immunology


An agent that acts to suppress the body’s natural immune response. This is totally understandable in tissue and organ transplants, and in some dangerous inflammatory conditions, but nearly all anti-inflammatory medications are immunosuppressant, including cortisone, antihistamines, and even aspirin. Some medical radicals are convinced that the chronic viral and fungal disorders of our age are partially facilitated by such medications.... immunosuppressant


An adjective meaning lack of an opening. For example, occasionally the ANUS fails to develop properly, resulting in partial or complete obstruction of the opening. Sometimes pubertal girls have an imperforate HYMEN which obstructs the opening to the VAGINA and prevents menstrual ?ow of blood draining to the exterior.... imperforate

Infantile Spasms

Also known as salaam attacks, these are a rare but serious type of EPILEPSY, usually starting in the ?rst eight months of life. The spasms are short and occur as involuntary ?exing of the neck, arms, trunk and legs. They may occur several times a day. If the baby is sitting, it may collapse into a ‘salaam’ position; more usually there is a simple body jerk, sometimes accompanied by a sudden cry. An electroencephalogram (see ELECTROENCEPHALOGRAPHY (EEG)) shows a picture of totally disorganised electrical activity called hypsarrhythmia. The condition results from any one of many brain injuries, infections or metabolic insults that may have occurred before, during, or in the ?rst few months after birth. Its importance is that in most cases, the baby’s development is seriously affected such that they are likely to be left with a profound learning disability. Consequently, prompt diagnosis is important. Treatment is with CORTICOSTEROIDS or with certain anti-convulsants – the hope being that prompt and aggressive treatment might prevent further brain damage leading to learning disability.... infantile spasms

Informed Consent

Ingrowing Toenail

The sides of the toenail curve downwards, resulting in in?ammation of the skin next to the nail which spreads to the base of the nail. The skin and nail base may become painful and badly infected. If antibiotics and local dressing do not cure the condition, surgery to remove part of the nail will be required.... ingrowing toenail

Inguinal Hernia

An extrusion of the abdominal PERITONEUM, sometimes containing a loop of bowel, through natural openings in the region of either groin (see HERNIA).... inguinal hernia


A method of applying drugs in a ?nely divided or gaseous state, so that, when breathed in, they may come into contact with the nose, throat and lungs. There are two chief means by which drugs are mingled with the air and so taken in by breathing: these are traditional steam inhalations, and modern aerosol devices which deliver a ?ne spray direct into the mouth. (See INHALANTS; INHALER.)... inhalation


Inhibition means arrest or restraint of some process e?ected by nervous in?uence. The term is applied to the action of certain inhibitory nerves: for example, the vagus nerve which contains ?bres that inhibit or control the action of the heart. The term is also applied generally to the mental processes by which instinctive but undesirable actions are checked by a process of self-control.... inhibition


The process by which infective material is brought into the system through a small wound in the skin or in a mucous membrane. Many infectious diseases are contracted by accidental inoculation of microbes – as is blood-poisoning (see SEPTICAEMIA). Inoculation is now used as a preventive measure against many infectious diseases. (See also VACCINE.)... inoculation


An o?cial inquiry conducted by a CORONER into the cause of an individual’s death. The coroner is a judicial o?cer who, when a death is sudden, unexpected or occurs in suspicious circumstances, considers the results of medical and legal investigation and, sitting with a jury or on his or her own, makes the conclusions public. He/she has wide powers, and, in deaths of uncertain cause, no o?cial death certi?cate can be issued without his or her approval. A coroner may be legally or medically quali?ed (or both). In Scotland the comparable o?cer is the procurator ?scal.... inquest


A person’s knowledge of him or herself. The description is especially relevant to a person’s realisation that he or she has psychological dif?culties. Thus, someone with a psychosis (see MENTAL ILLNESS) lacks insight. Insight also refers to an individual’s concept of his or her personality and problems.... insight


A tumour in the beta cells in the Islets of Langerhans in the PANCREAS that produces insulin. Symptoms of HYPOGLYCAEMIA occur. Treatment is surgical removal or oral administration of diazoxide.... insulinoma


A POLYPEPTIDE hormone (see HORMONES) produced in the PANCREAS by the beta cells of the ISLETS OF LANGERHANS. It plays a key role in the body’s regulation of CARBOHYDRATE, FAT, and PROTEIN, and its de?ciency leads to DIABETES MELLITUS. Diabetic patients are described as type 1 (insulin dependent), or type 2 (non-insulin dependent), although many of the latter may need insulin later on, in order to maintain good control.

Insulin is extracted mainly from pork pancreas and puri?ed by crystallisation; it may be made biosynthetically by recombinant DNA technology using Escherichia coli, or semisynthetically by enzymatic modi?cation of porcine insulin to produce human insulin. The latter is the form now generally used, although some patients ?nd it unsuitable and have to return to porcine insulin.

The hormone acts by enabling the muscles and other tissues requiring sugar for their activity to take up this substance from the blood. All insulin preparations are to a greater or lesser extent immunogenic in humans, but immunological resistance to insulin action is uncommon.

Previously available in three strengths, of 20, 40, and 80 units per millilitre (U/ml), these have now largely been replaced by a standard strength of 100 U/ml (U100). Numerous different insulin preparations are listed; these differ in their speed of onset and duration of action, and hence vary in their suitability for individual patients.

Insulin is inactivated by gastrointestinal enzymes and is therefore generally given by subcutaneous injection, usually into the upper arms, thighs, buttocks, or abdomen. Some insulins are also available in cartridge form, which may be administered by injection devices (‘pens’). The absorption may vary from di?erent sites and with strenuous activity. About 25 per cent of diabetics require insulin treatment: most children from the onset, and all patients presenting with ketoacidosis. Insulin is also often needed by those with a rapid onset of symptoms such as weight loss, weakness, and sometimes vomiting, often associated with ketonuria.

The aim of treatment is to maintain good control of blood glucose concentration, while avoiding severe HYPOGLYCAEMIA; this is usually achieved by a regimen of preprandial injections of short-acting insulin (often with a bedtime injection of long-acting insulin). Insulin may also be given by continuous subcutaneous infusion with an infusion pump. This technique has many disadvantages: patients must be well motivated and able to monitor their own blood glucose, with access to expert advice both day and night; it is therefore rarely used.

Hypoglycaemia is a potential hazard for many patients converting from porcine to human insulin, because human insulin may result in them being unaware of classical hypoglycaemic warning symptoms. Drivers must be particularly careful, and individuals may be forbidden to drive if they have frequent or severe hypoglycaemic attacks. For this reason, insurance companies should be warned, and diabetics should – after taking appropriate medical advice – either return to porcine insulin or consider stopping driving.... insulin

Intervertebral Disc

The ?brous disc that acts as a cushion between the bony vertebrae (see SPINAL COLUMN), enabling them to rotate and bend one on another. The disc tends to degenerate with age and may get ruptured and displaced – prolapsed or slipped disc – as a result of sudden strenuous action. Prolapsed disc occurs mainly in the lower back; it is more common in men than in women, and in the 30–40 age group.... intervertebral disc


All the alimentary canal beyond below the stomach. In it, most DIGESTION is carried on, and through its walls all the food material is absorbed into the blood and lymph streams. The length of the intestine in humans is about 8·5–9 metres (28–30 feet), and it takes the form of one continuous tube suspended in loops in the abdominal cavity.

Divisions The intestine is divided into small intestine and large intestine. The former extends from the stomach onwards for 6·5 metres (22 feet) or thereabouts. The large intestine is the second part of the tube, and though shorter (about 1·8 metres [6 feet] long) is much wider than the small intestine. The latter is divided rather arbitrarily into three parts: the duodenum, consisting of the ?rst 25–30 cm (10–12 inches), into which the ducts of the liver and pancreas open; the jejunum, comprising the next 2·4–2·7 metres (8–9 feet); and ?nally the ileum, which at its lower end opens into the large intestine.

The large intestine begins in the lower part of the abdomen on the right side. The ?rst part is known as the caecum, and into this opens the appendix vermiformis. The appendix is a small tube, closed at one end and about the thickness of a pencil, anything from 2 to 20 cm (average 9 cm) in length, which has much the same structure as the rest of the intestine. (See APPENDICITIS.) The caecum continues into the colon. This is subdivided into: the ascending colon which ascends through the right ?ank to beneath the liver; the transverse colon which crosses the upper part of the abdomen to the left side; and the descending colon which bends downwards through the left ?ank into the pelvis where it becomes the sigmoid colon. The last part of the large intestine is known as the rectum, which passes straight down through the back part of the pelvis, to open to the exterior through the anus.

Structure The intestine, both small and large, consists of four coats, which vary slightly in structure and arrangement at di?erent points but are broadly the same throughout the entire length of the bowel. On the inner surface there is a mucous membrane; outside this is a loose submucous coat, in which blood vessels run; next comes a muscular coat in two layers; and ?nally a tough, thin peritoneal membrane. MUCOUS COAT The interior of the bowel is completely lined by a single layer of pillar-like cells placed side by side. The surface is increased by countless ridges with deep furrows thickly studded with short hair-like processes called villi. As blood and lymph vessels run up to the end of these villi, the digested food passing slowly down the intestine is brought into close relation with the blood circulation. Between the bases of the villi are little openings, each of which leads into a simple, tubular gland which produces a digestive ?uid. In the small and large intestines, many cells are devoted to the production of mucus for lubricating the passage of the food. A large number of minute masses, called lymph follicles, similar in structure to the tonsils are scattered over the inner surface of the intestine. The large intestine is bare both of ridges and of villi. SUBMUCOUS COAT Loose connective tissue which allows the mucous membrane to play freely over the muscular coat. The blood vessels and lymphatic vessels which absorb the food in the villi pour their contents into a network of large vessels lying in this coat. MUSCULAR COAT The muscle in the small intestine is arranged in two layers, in the outer of which all the ?bres run lengthwise with the bowel, whilst in the inner they pass circularly round it. PERITONEAL COAT This forms the outer covering for almost the whole intestine except parts of the duodenum and of the large intestine. It is a tough, ?brous membrane, covered upon its outer surface with a smooth layer of cells.... intestine

Pre?x indicating inside or within. For example, intracellular: within a cell; intra-articular: within a joint.... intra


A form of obstruction of the bowels in which part of the INTESTINE enters within that part immediately beneath it. This can best be understood by observing what takes place in the ?ngers of a tightly ?tting glove as they turn outside-in when the glove is pulled o? the hand. Mostly, the condition affects infants. Often it occurs during the course of a viral infection or a mild attack of gastroenteritis, or it may be that swelling of lymphoid tissue in the gut provokes the event. The point at which it most often occurs is the junction between the small and the large intestines, the former passing within the latter. The symptoms are those of intestinal obstruction in general (see INTESTINE, DISEASES OF – Obstruction), and in addition there is often a discharge of blood-stained mucus from the bowel. Unless the symptoms rapidly subside, when it may be assumed that the bowel has righted itself, treatment consists of either hydrostatic reduction by means of a barium or air ENEMA, or an operation. At operation the intussusception is either reduced or, if this not possible, the obstructed part is cut out and the ends of the intestine then stitched together. If treated adequately and in time, the mortality is now reduced to around 1 per cent. The condition may recur in about 5 per cent of patients.... intussusception


The root of Cephaëlis ipecacuanha, a Brazilian shrub. It contains an alkaloid, emetine, which acts as an irritant when brought into contact with the interior of the stomach, producing vomiting. Formerly used to induce vomiting among young children after poisoning and if still alert, but now of uncertain value, it was used in many traditional expectorant mixtures

(see EXPECTORANTS) given in the treatment of BRONCHITIS. (See POISONS.)... ipecacuanha


The operation by which a hole is made in the iris of the EYE – as, for example, in the treatment of GLAUCOMA or as part of CATARACT surgery.... iridectomy

Irritable Bowel Syndrome

(IBS) This is a common and generally benign condition of the colon, taking different forms but usually characterized by alternating constipation and diarrhea. There is often some pain accompanying the diarrhea phase. The bowel equivalent of spasmodic asthma, its main cause is stress, often accompanied by a history of GI infections. Adrenalin stress slows the colon and causes constipation, followed by a cholinergic rebound overstimulation of the colon. It is also called spastic colon, colon syndrome, mucous colitis, even chronic colitis. True colitis is a potentially or actually serious pathology.... irritable bowel syndrome


An agent that causes inflammation... irritant


Ischium is the bone which forms the lower and hinder part of the pelvis. It bears the weight of the body in sitting.... ischium


The use of naturally occurring isotopes, or arti?cially produced X-rays, in the killing of tumour cells. The amount of radiation is the adsorbed dose; the SI unit is the gray (Gy).

Di?erent tumours seem to be particularly sensitive to radiation; radiotherapy plays an important role in the management of germ-cell tumours (SEMINOMA; TERATOMA) and lymphomas (see LYMPHOMA). Many head and neck tumours, gynaecological cancers, and localised prostate and bladder cancers are curable with radiotherapy. It may be used to reduce the pain

– for example, from bone metastases.

Unwanted effects Generalised: lethargy, loss of appetite. Skin: ERYTHEMA, dry desquamation with itching, moist desquamation. Patients should keep the treated area(s) dry and clean and avoid soap, antiseptic mouthwashes, smoking and spicy food if possible. (See ISOTOPE; RADIATION SICKNESS; RADIOTHERAPY).... irradiation


One of the anti-tuberculous drugs. It has the advantages of being relatively non-toxic and of being active when taken by mouth. Unfortunately, like streptomycin, it may render the Mycobacterium tuberculosis resistant to its action. This tendency to produce resistance is considerably reduced if it is given in conjunction with RIFAMPICIN and PYRAZINAMIDE.... isoniazid


See PRURITUS.... itching


A triazole antifungal drug taken orally for oropharyngeal and vulvovaginal CANDIDA, PITYRIASIS versicolor, and tinea corporis and pedis (see under RINGWORM). It is also used for systemic fungal infections such as ASPERGILLOSIS, candidiasis and cryptococcosis where other fungicidal drugs have not worked. Itraconazole is metabolised in the liver so should not be given to patients who have or have had liver disease. The drug can be given as maintenance treatment of AIDS (see AIDS/HIV) patients to prevent resurgence of underlying fungal disease to which they are vulnerable. (See FUNGAL AND YEAST INFECTIONS.)... itraconazole

Lactose Intolerance

is due to lack in the INTESTINE of the ENZYME known as LACTASE which is responsible for the digestion of lactose, the sugar in milk. The result is that drinking milk or eating milk-containing products is followed by nausea, a sensation of bloating, or distension, in the gut, abdominal pain and diarrhoea. (Similar disturbances after taking milk may also occur in those who do not lack lactase but have an allergy to milk protein). Treatment is by means of a low-lactose diet avoiding fresh or powdered milk and milk puddings. Many can tolerate fermented milk products, as well as the small amounts of milk used in baking and added to margarine and sausages. However, infamts may have to be fed exclusively on a lactose-free formula as even breast milk may produce symptoms.... lactose intolerance

Myocardial Infarction

Osteogenesis Imperfecta

A hereditary disease due to an inherited abnormality of COLLAGEN. It is characterised by extreme fragility of the skeleton, resulting in fractures and deformities. It may be accompanied by blue sclera (the outermost, normally white coat of the eyeball), transparent teeth, hypermobility (excessive range of movement) of the joints, deafness, and dwar?sm (shortness of stature). The exact cause is not known, although there is some evidence that it may be associated with collagen formation. Parents of affected children can obtain help and advice from the Brittle Bone Society.... osteogenesis imperfecta

Pelvic Inflammatory Disease

(PID) Also called salpingitis, the term is applied to infections of the fallopian tubes that follow or are concurrent with uterine and cervical infections. Gonorrhea and Chlamydia are the most common organisms, and the infection is usually begun through sexual contact, although metabolic imbalances, subtler systemic infections like a slow virus, the local insult of herpes or candidiasis, the sequela of medication or recreational drugs, birth control pills, even an IUD...all can alter the vaginal flora and induce inflammation sufficient to allow an endogenous organism to start the infection. PID after birth, on the other hand, is usually the result of staph or strep infections infecting injured membranes.... pelvic inflammatory disease

Whiplash Injury

An injury to the neck region caused by the neck being forcibly bent backwards and forwards (or the other way around). Car accidents are a common cause, when a driver or passenger is suddenly decelerated. The injury usually affects the ligaments, spinal joints and soft tissues of the neck. Subluxation (partial dislocation) of a cervical joint sometimes occurs and cervical vertebra may occasionally be fractured if the forces are severe. Pain and sti?ness of the neck result and these may worsen after a day or so. Treatment includes immobilisation of the neck in a collar, and analgesic and muscle-relaxing drugs. PHYSIOTHERAPY may be necessary. The patient usually recovers fully but may take several weeks to do so.... whiplash injury

Aortic Incompetence

See also REGURGITATION. This is the back ?ow of blood through the AORTIC VALVE of the HEART into the left ventricle, caused by an incompetent valve. The failure to close may be caused by a congenital defect or by damage from disease. The defect may be cured by surgical replacement of the damaged valve with an arti?cial valve. (See HEART, DISEASES OF.)... aortic incompetence

Carbonic Anhydrase Inhibitor

A drug that curbs the action of an ENZYME in the blood controlling the production of carbonic acid or bicarbonate from CARBON DIOXIDE (CO2). Called carbonic anhydrase, the enzyme is present in ERYTHROCYTES and it has a key part in maintaining the acid-base balance in the blood. Inhibiting drugs include ACETAZOLAMIDE and DORZOLAMIDE, and these are used as weak DIURETICS to reduce the increased intraocular pressure in ocular hypertension or open-angle GLAUCOMA (see EYE, DISORDERS OF).... carbonic anhydrase inhibitor

Confidence Interval

A range of values for a variable of interest, e.g. a rate, constructed so that this range has a specified probability of including the true value of the variable. The specified probability is called the confidence level, and the end points of the confidence interval are called the confidence limits.... confidence interval

Cost Of Illness

The personal cost of acute or chronic disease. The cost to the patient may be an economic, social or psychological cost or loss to himself, his family or community. The cost of illness may be reflected in absenteeism, productivity, response to treatment, peace of mind, quality of life, etc. It differs from health care costs in that this concept is restricted to the cost of providing services related to the delivery of health care, rather than the impact on the personal life of the patient. See “burden of disease”.... cost of illness

Donor Insemination

Use of the SEMEN of an anonymous donor to produce fertilisation in cases of INFERTILITY where the male partner has OLIGOSPERMIA or IMPOTENCE. The donor is chosen for ethnic and physiognomic similarity to the male partner and is screened for transmissible diseases

(e.g. HIV, syphilis, hepatitis, gonorrhoea, and genetic disorders). Insemination is performed at the time of ovulation by introducing the semen into the upper vagina. Semen may be fresh or have been stored frozen in liquid nitrogen. (See ARTIFICIAL INSEMINATION.)... donor insemination

Compressed Air Illness

Also known as caisson disease, this affects workers operating in compressed-air environments, such as underwater divers and workers in caissons (such as an ammunition wagon, a chest of explosive materials, or a strong case for keeping out the water while the foundations of a bridge are being built; derived from the French caisse, meaning case or chest). Its chief symptoms are pains in the joints and limbs (bends); pain in the stomach; headache and dizziness; and paralysis. Sudden death may occur. The condition is caused by the accumulation of bubbles of nitrogen in di?erent parts of the body, usually because of too-rapid decompression when the worker returns to normal atmospheric presure – a change that must be made gradually.... compressed air illness

Health Impact Assessment

This is a structured, multi-disciplinary process for assessing and improving the health consequences of projects and policies in the non-health sector. It combines a range of qualitative and quantitative evidence in preparing conclusions. Applications of the assessments include appraisal of national policies, local urban planning, and the progress of transport, water and agricultural projects.... health impact assessment

Gamete Intrafallopian Transfer (gift)

Another method of helping infertile couples. In over half of women diagnosed as infertile, the Fallopian tubes are normal, and in many it is unknown why they cannot conceive – although some have ENDOMETRIOSIS.

Eggs are obtained and mixed with the partner’s semen, then introduced into the woman’s Fallopian tubes for fertilisation to take place. The fertilised egg travels to the uterus where IMPLANTATION occurs and pregnancy proceeds. A variation of GIFT is zygote intrafallopian transfer (ZIFT) in which early development of the fertilised eggs happens in the laboratory before the young embryo is transferred to the Fallopian tubes. GIFT is best used in couples with unexplained infertility or with minor degrees of male or female cervical factor infertility. The success rate is about 17 per cent. (See also ARTIFICIAL INSEMINATION.)... gamete intrafallopian transfer (gift)

A generally unexpected, so unpredictable, abnormal reaction to a drug caused by a constitutional defect in the patient. In some cases the underlying disorder is already known or discovered after the ?rst event, so that the drug in question can be avoided thereafter. The abnormal sensitivity of patients with PORPHYRIAS to BARBITURATES is an example. Hereditary biochemical defects of red blood cells are responsible for many drug-induced haemolytic anaemias (see under ANAEMIA) and for FAVISM. Porphyria variegata, the South African variety of porphyria, is an example of an inborn error of metabolism which was without serious symptoms until the advent of barbiturate drugs, prescription of which is now strongly discouraged. If anyone with this metabolic disorder takes barbiturates, the consequences may be fatal.... idiosyncrasy

The characteristic of a substance that can provoke an immune response (see IMMUNITY). This includes how ‘foreign’ a substance entering or contacting the body is; route of entry; dose; number and period of exposure to antigen; and the genetic make-up of the host. The characteristics of molecules that determine immunogenicity are:

Foreignness: molecules recognised as ‘self’ are generally not immunogenic; the body tolerates these self-molecules. To be immunogenic, molecules must be recognised as non-self or foreign.

Molecular size: proteins with high molecular weights (over 100,000) are the most e?ective immunogens; those below 10,000 are weakly immunogenic; and small ones, for example, AMINO ACIDS, are non-immunogenic.

Chemical complexity: the greater the chemical complexity, the more immunogenic the substance.

Dosage, route and timing of antigen administration: all these are important factors.... immunogenicity


Body proteins that act as antibodies. 1. IgG: The immunoglobulin that can be measured in the serum approximately two weeks after a challenge by an antigen. Can cross the placenta from mother to foetus. 2. IgM: The immunoglobulin that can be measured very soon after a challenge by an antigen. The level returns to a non-measurable level very quickly and so this measurement is useful as a test for recent envenomation (or illness). Cannot cross the placenta from mother to foetus. Presence in a neonate therefore indicates infection of the body. 3. IgE: Reaginic antibody; immunoglobulin found in association with allergic or homocytotrophic responses. 4. IgA: Secretory antibody; immunoglobulin found in nonvascular fluids, such as the saliva, bile, aqueous humor, synovial fluide etc.... immunoglobulins


The term given to suppression of harmful immune responses (see IMMUNITY), the most obvious application being the prevention of organ rejection by people who receive kidney, heart or bone-marrow transplants (see TRANSPLANTATION). Immunosuppression is also used in certain diseases in a way that is non-speci?c – that is, it inhibits the entire immune system, not just harmful reactions. CORTICOSTEROIDS are the commonest dugs used in this way, as are METHOTREXATE and AZATHIOPRINE. Tacrolimus, a macrolide (see MACROLIDES) IMMUNOSUPPRESSANT, is used not only for engrafted patients but also in treating eczema (see DERMATITIS).

There has been a rapid introduction in recent years of monoclonal antibodies which prevent T-cells from proliferating. They can be recognised by the su?x ‘mab’ (standing for monoclonal antibody) and include rituximab and alemtuzumab. In?iximab, used in CROHN’S DISEASE and RHEUMATOID ARTHRITIS, inhibits tumour necrosis factor alpha.... immunosuppression

The birth of o?spring to parents who are closely related (see CONSANGUINOUS). In traditional rural communities, marriage between cousins was common and this could lead to a higher-than-average number of children with congenital anomalies or learning diffculties. This is now seen in certain ethnic groups who have brought the custom of inbreeding with them to their new homes in the western world.... inbreeding

Incompetence is a term applied to the valves of the heart when, as a result of disease in the valves or alterations in size of the chambers of the heart, the valves become unable to close the ori?ces which they should protect. (See HEART, DISEASES OF.)... incompetence


The period elapsing between the time when a person becomes infected by some agent and the ?rst appearance of the symptoms of the disease. Most acute infectious diseases have fairly definite periods of incubation, and it is of great importance that people who have run the risk of infection should know the length of time which must elapse before they can be sure whether or not they are to contract the disease in question. A person who has been exposed to infection is, during the incubation period, technically known as a contact. By isolating and watching contact cases, medical o?cers can often successfully check a threatened EPIDEMIC.

It must be noted that diseases are not communicated to others by a person who is incubating an illness. Some diseases, however, such as MEASLES, become infectious as soon as the ?rst symptoms set in after the incubation period is over; others, like SCARLET FEVER and SMALLPOX, are not so infectious then as in their later stages. The incubation period for any given disease is remarkably constant, although in the case of a severe attack the incubation is usually slightly shortened, and if the oncoming attack is a mild one, the period may be lengthened. All, however, may take a few days longer than the time stated to show themselves (see INFECTION), and several – especially WHOOPINGCOUGH – may be di?cult to recognise in their early stages.

Indian Senna

Cassia senna


San: Svarnapatri;

Hin: Sanay, Sana Ka Patt;

Ben: Sonamukhi;

Mal: Sunnamukki, Chonnamukki, Nilavaka;

Tam: Nilavirai, Nilavakai;

Tel: Netatangedu

Importance: Indian Senna or Tinnevelly senna is a shrub very highly esteemed in India for its medicinal value. The leaves are useful in constipation, abdominal disorders, leprosy, skin diseases, leucoderma, splenomegaly, hepatopathy, jaundice, helminthiasis, dyspepsia, cough, bronchitis, typhoid fever, anaemia, tumours and vitiated conditions of pitta and vata (Warrier et al,1994). It is used in Ayurvedic preparations; “Pancha Sakara Churna”, “Shat Sakara Churna” and “Madhu Yastyadi Churna” used for constipation. Its use is widespread in Unani system and some of the important products of this system containing senna are “Itrifal Mulayyin”, “Jawarish Ood Mulayyin”, “Hab Shabyar”, “Sufuf Mulliyin”, “Sharbat Ahmad Shahi”, etc. used as a mild laxative (Thakur et al, 1989).

Distribution: The plant is of Mediterranean origin. It is found in Somalia, Saudi Arabia, parts of Pakistan and Kutch area of Gujarat. It is largely cultivated in Tirunelveli, Ramanathapuram, Madurai and Salem districts of Tamil Nadu.

Botany: The genus Cassia, belonging to the family Caesalpiniaceae, comprises of a number of species, namely,

C. senna Linn. syn. C. angustifolia Vahl.

C. absus Linn.

C. alata Linn.

C. auriculata Linn.

C. burmanni Wight. syn. C. obovata (Linn.) Collad.

C. glauca Lam.

C. javanica Linn.

C. mimosoides Linn.

C. obtusifolia Linn. syn. C. tora Linn.

C. occidentalis Linn.

C. pumila Lam.

C. slamea Lam.

C. acutifolia Delile.

C. sophera Linn.

C. senna is a shrub or undershrub, 60-75cm in height with pale subterete or obtusely angled erect or spreading branches. Leaves are paripinnate. Leaflets are 5-8 in number, ovate-lanceolate and glabrous. Flowers are yellowish, many and arranged in axillary racemes. Fruits are flat legumes, greenish brown to dark brown and nearly smooth (Chopra et al,1980, Warrier et al,1994).

In commerce, the leaves and pods obtained from C. senna are known as “ Tinnevelly Senna” and those from C. acutifolia Delile. as “Alexandrian Senna”. The leaves of C. acutifolia are narrower than C. senna, otherwise both resemble to a large extent (Thakur et al, 1989). All the true Sennas have the portions of their leaves unequally divided. In some kinds the lower part of one side is reduced to little more than a line in breadth, while the other is from a quarter to half an inch in breadth. The drug known under the name of East Indian Senna is nearly free from adulteration; and as its properties appear identical with those of the Alexandrian and the price being less, it probably will supersede it in general practice. Its size and shape readily identify it (Graves, 1996).

Agrotechnology: The plant requires a mild subtropical climate with warm winters which are free from frost for its growth. Semiarid areas with adequate irrigation facilities are ideal for cultivation. Areas having high rainfall, humidity and poor drainage are not suitable. Light or medium loamy soils with adequate drainage and pH varying from 7.0-8.2 are preferable. In South India both summer and winter crops are possible. The plant is propagated by seeds. The seed rate required is 15-20kg/ha. Seeds are sown in October-November (winter rainfed crop) or in February-March (irrigated crop). Higher seed rate is required for unirrigated crop. Seeds are sown in lines 30cm apart. Application of 5-10t of FYM/ha before planting or raising a green manure crop is beneficial. About 40kg N and 25-50kg P2O5/ha applied as basal dressing and 40kg N/ha applied in 2 split dozes as top dressing gave better yield. While the rainfed crop is grown without irrigation, the irrigated crop requires 5-8 light irrigations during the entire growing season. The crop requires 2-3 weedings and hoeings in order to keep it free from weeds. Alternaria alternata causes leaf spot and dieback but the disease is not serious. In North India, the plant is attacked by the larvae of butterfly Catopsilia pyranthe which can be controlled by planting the crop in March-April instead of June-July. Under irrigated conditions, the first crop is obtained after 90 days of planting. The leaves are stripped by hand when they are fully green, thick and bluish-green in colour. The second crop is taken 4 weeks after the first harvest and the third 4-6 weeks after the second one. The last harvest of leaves is done when the entire crop is harvested along with the pods. Yield under irrigated conditions is nearly1.4t of leaves and 150kg pods/ha and under unirrigated conditions is 500-600kg leaves and 80-100kg pods/ha. The leaves are dried in thin layers under shade so as to retain the green colour and the pods are hung for 10-12 days to get dried. The leaves and pods are cleaned, graded and marketed (Husain et al, 1993).

Properties and Activity: Leaves contain glucose, fructose, sucrose and pinnitol. Mucilage consists of galactose, arabinose, rhamnose and galacturonic acid. Leaves also contain sennoside-C(8,8’- diglucoside of rhein-aloe-emodin-dianthrone). Pods contain sennosides A and B, glycoside of anthraquinones rhein and chrysophanic acid. Seeds contain -sitosterol (Husain et al, 1992). Leaves and pods also contain 0.33% -sterol and flavonols-kaempferol, kaempferin, and iso-rhamnetin. Sennoside content of C. acutifolia is higher ranging from 2.5% to 4.5% as compared to C. angustifolia ranging from 1.5 % to 2.5%.

The purgative activity of Senna is attributed to its sennosides. The pods cause lesser griping than the leaves. Leaf and pod is laxative. The leaves are astringent, bitter, sweet, acrid, thermogenic, cathartic, depurative, liver tonic, anthelmintic, cholagogue, expectorant and febrifuge.... indian senna

A mechanism for administering a drug in the form of a powder or aerosol. mainly used by patients with ASTHMA. Inhalers are basically of two types: aerosol, and dry-powder inhaler. The former delivers the drug as an aerosol spray when the patient presses the top of the canister containing the drug; the latter works by putting a drug capsule in the end of the chamber and, when the patient presses the top, the capsule is pierced and the drug released. A variety of ‘spacing devices’ are available to use with pressurised (aerosol) inhalers, providing metered doses. The space introduced between the inhaler and the mouth reduces the velocity of the aerosol and thus the impact it has on the oropharynx. More time is therefore allowed for evaporation of the propellant, with a greater concentration of drug particles being inhaled. Inhalers with larger spacing devices and a one-way valve are very e?ective and particularly useful for children and patients needing higher doses of the drug.

Intrauterine Insemination

A method of helping CONCEPTION to occur when a man is infertile (see INFERTILITY) because his sperm (see SPERMATOZOON) cannot penetrate either the cervical mucus at the entrance of the UTERUS or the barriers that surround the OVUM. The sperm, often treated chemically beforehand to increase motility, are injected directly into the uterus via the VAGINA.... intrauterine insemination

Intracytoplasmic Sperm Injection

Intracytoplasmic sperm injection (ICSI) is the most signi?cant therapeutic advance in male INFERTILITY treatment in the past 30 years. The technique is used when in vitro fertilisation (IVF – see under ASSISTED CONCEPTION) is not possible because the man has very few, motile, normal sperm (see SPERMATOZOON), or when previous attempts at IVF have not produced a fertilised EMBRYO. ICSI requires a single sperm which is injected directly into the cytoplasm of an egg previously retrieved from the woman. Once fertilised, the embryo is transferred to her UTERUS. For men with no sperm in the semen, it may be possible to retrieve sperm by needle aspiration of the EPIDIDYMIS under local anaesthetic (see ANAESTHESIA). Other techniques involve microsurgical retrieval from the epididymis or TESTICLE under a general anaesthetic. Potential complications include scrotal pain, bruising, HAEMATOMA formation and infection. ICSI and surgical sperm-retrieval require extensive training and expertise and is currently available in only a few selected

infertility units. Safety concerns relate to a higher-than-expected rate of abnormalities in the SEX CHROMOSOMES after ICSI, and also the potential risk of transmitting paternal genetic defects in the Y chromosome to sons born after ICSI.... intracytoplasmic sperm injection

Treatment is by a combination of antibiotics and surgery.... ischiorectal abscess

Irritable Bowel Syndrome (ibs)

A disorder of the intestinal tract that affects its motility and causes abdominal distension and irregular defaecation. Traditional, but now discarded, names have been spastic or irritable colon. The disease affects around 20 per cent of the general population but in most it is no more than a minor nuisance. The causes are not fully understood, but it is generally believed that symptoms develop in response to psychological factors, changed gastrointestinal motility, or altered visceral sensation. About 50 per cent of patients meet criteria for a psychiatric diagnosis. Anxiety, depression, neurosis, panic attacks, acute disease are among possible triggering factors. Some patients have diarrhoea, others are constipated, and some alternate between the two. Many have increased sensitivity to distension of the intestine. Dietary factors such as intolerance to dairy products and wheat are apparent in certain patients.

Common features of IBS include:

abdominal distension.

altered bowel habit.

colicky lower abdominal pain, eased by defaecation.

mucous discharge from rectum.

feelings of incomplete defaecation.

Investigations usually produce normal results. Positive diagnosis in people under 40 is usually straightforward. In older patients, however, barium ENEMA, X-rays and COLONOSCOPY should be done to exclude colorectal cancer.

Reassurance is the initial and often e?ective treatment. If this fails, treatment should be directed at the major symptoms. Several months of the antidepressant amitriptyline (see ANTIDEPRESSANT DRUGS) may bene?t patients with intractable symptoms, given at a dose lower than that used to treat depression. The majority of patients follow a relapsing/remitting course, with episodes provoked by stressful events in their daily lives. (See also INTESTINE, DISEASES OF.)... irritable bowel syndrome (ibs)

Itch is a popular name for SCABIES.... itch


This is a form of a chemical element with the same chemical properties as other forms, but which has a di?erent atomic mass. It contains an identical number of positively charged particles called protons, in the nucleus, giving it the same atomic number, but the numbers of neutrons di?er. A radioactive isotope, or radionuclide, is one that decays into other isotopes, and in doing so emits alpha, beta or gamma radiation.

Applications of radionuclides to diagnosis The use of radionuclides in diagnosis is based on the fact that it is possible to tag many of the substances normally present in the body with a radioactive label. Certain synthetic radioactive elements, such as technetium, can also be used. Because it is possible to detect minute quantities of radioactive material, only very small doses are needed, making the procedure a safe one. Furthermore the body pool of the material is therefore not appreciably altered, and metabolism is not disturbed. Thus in studies of iodine metabolism the ratio of radioactive atoms administered to stable atoms in the body pool is of the order of 1:1,000 million. By measuring radioactivity in the body, in blood samples, or in the excreta it is possible to gain information about the fate of the labelled substance, and hence of the chemically identical inactive material. Therefore it is theoretically possible to trace the absorption, distribution and excretion of any substance normally present in the body, provided that it can be tagged with a suitable radioactive label.

If the investigation necessitates tracing the path of the material through the body by means of external counting over the body surface, it is obviously essential to use an isotope that emits gamma radiation or positrons. If, however, only measurements on blood sample or excreta are required, it is possible to use pure beta emitters. Whole-body counters measure the total radioactivity in the body, and these are of great value in absorption studies.

Moving images can provide information on body functions such as the movements of the heart, blood ?ow, bile ?ow in the liver, and urine in the kidneys. The development of COMPUTED TOMOGRAPHY or CT scanning has replaced radionuclide scanning for some imaging procedures.

Five main groups of diagnostic uses may be de?ned:

(1) METABOLIC STUDIES The use of radioactive materials in metabolic studies is based on the fundamental property that all isotopes of an element are chemically identical. The radioactive isotope is used as a true isotope tracer – that is, when introduced into the body (in whatever form) it behaves in the same way as the inactive element. For example, isotopes of iodine are used to measure thyroid function (see THYROID GLAND), and isotopes of calcium enable kinetic studies of bone formation and destruction to be performed.... isotope

Mitral Incompetence

A defect in the MITRAL VALVE of the HEART which allows blood to leak from the left VENTRICLE into the left ATRIUM. It is also known as mitral regurgitation; incompetence may occur along with MITRAL STENOSIS. The left ventricle has to work harder to compensate for the faulty valve, so it enlarges, but eventually the ventricle cannot cope with the extra load and left-sided heart failure may develop. A common cause of mitral incompetence is RHEUMATIC FEVER or damage following a heart attack. The condition is treated with drugs to help the heart, but in severe cases heart surgery may be required.... mitral incompetence

Needle-stick Injury

Accidental perforation of the skin by an injection needle, commonly of the hand or ?nger and usually by a nurse or doctor administering a therapeutic injection.

Oroxylum Indicum

Vent. 453

Action: Emmenagogue, antispasmodic, carminative, expectorant. Leaves and seed— astringent, antispasmodic. Warm infusion of herb—promotes suppressed menstrual flow.

The herb contains about 3% volatile oil comprising sabinene hydrate, sa- binene, linalool, carvacrol, estrogole, eugenol and terpenes; flavonoids including luteolin-7-glucoside, dios- metin-7-glucoside, apigenin-7-gluco- side; rosmarinic acid, caffeic acid; and triterpenoids such as ursolic acid, olea- nolic acid, sterols.

Marjoram herb and oil exhibit antibacterial action. (German Commission E.) The herb contains arbutin and hydroxyquinone (a carcinogenic agent) in low concentrations. The herb is not suited for extended use. Topical application of hydroxyquinone leads to depigmentation of the skin. There is no reports of similar side effects with marjoram ointment. (German Commission E.)

Origanum vulgare Linn. (Wild Marjoram) contains volatile oil with a widely varying composition; major components include thymol, beta-bisabolene, caryophyllene, linalool and borneol; other constituents are similar to those of O. majorana.

The leaves of Wild Marjoram contain phenolic acids. The phenyl propionic acid and the phenyl glucoside showed antioxidant activity comparable to that of BHA, a synthetic antiox- idant.

Wild Marjoram preparations are used for bronchial catarrh and disturbances of the gastrointestinal tract in Unani medicine.

Prolapsed Intervertebral Disc

The SPINAL COLUMN is built up of a series of bones, known as vertebrae, placed one upon the other. Between these vertebrae lies a series of thick discs of ?bro-cartilage known as intervertebral discs. Each disc consists of an outer portion known as the anulus ?brosus, and an inner core known as the nucleus pulposus. The function of these discs is to give ?exibility and resiliency to the spinal column and to act as bu?ers against undue jarring. In other words, they are most e?cient shock-absorbers. They may, however, PROLAPSE, or protrude, between the two adjacent vertebrae. If this should happen they press on the neighbouring spinal nerve and cause pain. As the most common sites of protrusion are between the last two lumbar vertebrae and between the last lumbar vertebra and the sacrum, this means that the pain occurs in the back, causing LUMBAGO, or down the course of the sciatic nerve causing SCIATICA. The prolapse is most likely to occur in middle age, which suggests that it may be associated with degeneration of the disc involved, but it can occur in early adult life as well. It usually occurs when the individual is performing some form of exercise which involves bending or twisting, as in gardening. The onset of pain may be acute and sudden, or gradual and more chronic in intensity. (See also INTERVERTEBRAL DISC.)

Treatment varies, depending (amongst other things) on the severity of the condition. In the acute phase, rest in bed is advisable, along with ANALGESICS. Later, exercise and physiotherapy are helpful, and in some cases manipulation of the spine brings relief by allowing the herniated, or prolapsed, disc to slip back into position. The injection of a local anaesthetic into the spine (epidural ANAESTHESIA) is yet another measure that often helps the more chronic cases. If those measures fail, surgery to remove the prolapsed disc may be necessary, but the patient’s condition should be carefully reviewed before surgery is considered since success is not certain. An alternative form of treatment is the injection into the disc of chymopapain, an ENZYME obtained from the paw-paw, which dissolves the disc.... prolapsed intervertebral disc

Sex-linked Inheritance

The way in which a characteristic or an illness determined by the SEX CHROMOSOMES in an individual’s cells is passed on to the succeeding generation. Men have one X and one Y sex chromosome and women have two X chromosomes. Disorders that result from an abnormal number of sex chromosomes include KLINEFELTER’S SYNDROME, which affects only men, and TURNER’S SYNDROME, which affects mainly women. Recessive GENES on the X chromosome cause most other sex-linked characteristics; in women these may well be masked because one of their two X chromosomes carries a normal (dominant) gene. In men, who have just one X chromosome, no such masking occurs – so more men than women are affected by X-linked characteristics or diseases. (See also HEREDITY.)... sex-linked inheritance

Water Intoxication

A disorder resulting from excessive retention of water in the brain. Main symptoms are dizziness, headaches, confusion and nausea. In severe cases the patient may have ?ts (see SEIZURE) or lose consciousness. Several conditions can disturb the body’s water balance causing accumulation of water in the tissues. Heart or kidney failure, CIRRHOSIS of the liver and disorders of the ADRENAL GLANDS can all result in water retention. Other causes are stress as a result of surgery, when increased secretion of antidiuretic hormone (VASOPRESSIN) by the adrenal gland may occur. Treatment is of the underlying condition and the judicious use of DIURETICS, with careful monitoring of the body’s ELECTROLYTES.... water intoxication

Artificial Insemination

A form of assisted conception in which semen is introduced artificially into the uterus, instead of by sexual intercourse, with the aim of inducing pregnancy.

There are 2 types of artificial insemination: , artificial insemination with the semen of the woman’s male partner; and , insemination with a donor’s sperm. is usually used for couples who are unable to have intercourse, or if the man has a low sperm count or a low volume of ejaculate. It is also used when semen has been stored from a man prior to treatment (such as chemotherapy) that has made him sterile. is available to couples if the man is infertile or is a carrier of a genetic disease. It may also be used by a woman who wants children but has no male partner.

Insemination is timed to coincide with natural ovulation or may be combined with treatment to stimulate ovulation.... artificial insemination

Depot Injection

An intramuscular injection of a drug that gives a slow, steady release of its active chemicals into the bloodstream. Release of the drug is slowed by the inclusion of substances such as oil or wax. The release of the active drug can be made to last for hours, days, or weeks.

A depot injection is useful for patients who may not take their medication correctly.

It also prevents the necessity of giving a series of injections over a short period.

Hormonal contraceptives (see contraception, hormonal methods of), corticosteroid drugs, and antipsychotic drugs may be given by depot injection.

Side effects may arise due to the uneven release of the drug into the bloodstream.... depot injection

A distorted sensation based on misinterpretation of a real stimulus (for example, a pen is seen as a dagger). It is differs from a hallucination, in which a perception occurs without any stimulus.Usually, illusions are brief and can be understood when explained. They may be due to tiredness or anxiety, to drugs, or to forms of brain damage. Delirium tremens is a classic inducer of illusions. imaging techniques Techniques that produce images of structures within the body. The most commonly used and simplest techniques are X-rays (to view dense structures such as bone) and contrast X-rays, in which a medium, such as barium, that is opaque to X-rays is introduced into the body. Contrast X-ray techniques include barium X-ray examinations (used to examine the oesophagus, the stomach and the small intestine); cholecystography (used to visualize the gallbladder and common bile duct); bronchography (to view the airways connecting the windpipe to the lungs); angiography and venography (to provide images of the blood vessels); intravenous urography (to visualize the kidneys and urinary tract); and ERCP (by which the pancreatic duct and biliary system are examined).

Many X-ray imaging techniques have been superseded by newer procedures. These include ultrasound scanning, MRI (magnetic resonance imaging), PET scanning, and radionuclide scanning. However, X-rays are used in CT scanning. Some of these techniques use computers to process the raw imaging data and produce the actual image. Others can produce images without a computer, although one may be used to enhance the image. imipramine A tricyclic antidepressant drug most commonly used as a longterm treatment for depression. Possible adverse effects include excessive sweating, blurred vision, dizziness, dry mouth, constipation, nausea, and, in older men, difficulty passing urine.... illusion


The process of inducing immunity as a preventive measure against infectious diseases. Immunization may be active or passive. In the passive form,antibodies are injected into the blood to provide immediate but short-lived protection against specific bacteria, viruses, or toxins. Active immunization, also called vaccination, primes the body to make its own antibodies and confers longer-lasting immunity.

Routine childhood immunization programmes exist for diseases such as diphtheria, pertussis, and tetanus (see DPT vaccination), haemophilus influenza (Hib), measles, mumps, and rubella (see MMR vaccination), meningitis C, and poliomyelitis. Additional immunizations before foreign travel may also be necessary (see travel immunization).

Most immunizations are given by injection, and usually have no after effects. However, some vaccines cause pain and swelling at the injection site and may produce a slight fever or flu-like symptoms. Some may produce a mild form of the disease. Very rarely, severe reactions occur due, for example, to an allergy to 1 of the vaccine’s components. Not all vaccines provide complete protection. Cholera and typhoid fever vaccinations, in particular, give only partial protection.

People with immunodeficiency disorders, widespread cancer, those taking corticosteroid drugs, or those who have previously had a severe reaction to a vaccine should not be immunized. Some vaccines should not be given to young children or during pregnancy.... immunization

A type of protein found in blood and tissue fluids, also known as an antibody. Such proteins are produced by B-lymphocytes (a type of white blood cell), and their function is to bind to substances in the body that are recognized as foreign antigens.

Immunoglobulin G (IgG) is the major class of immunoglobulin of the 5 in the blood (IgA, IgD, IgE, IgG, and IgM). Its molecule consists of 2 parts: 1 binds to an antigen; the other binds to other cells, which then engulf the microorganisms bearing the antigen.

Immunoglobulins can be extracted from the blood of people who have recovered from certain infectious diseases and used for passive immunization.... immunoglobulin

All You Need To Know About Iced Tea!

While many people love drinking hot tea during the winter, you can’t really do the same during summer. Drinking something hot won’t help you fight off the heat. However, if you love tea and you don’t want to give up on it, try iced tea! Cold and refreshing, you’ll surely enjoy it during the hot days of summer. Why Iced Tea? During hot summer days, a cold beverage is the best solution. Sodas might be tempting, but they’re far from the best solution. Fruit juices sound good, but if you’re a fan of teas, then iced tea sounds just as tempting. It is refreshing and, based on your preferences, you can enjoy the iced tea in many fruity flavors. There are various kinds of recipes which you can follow, in order to drink a pleasant iced tea. Iced Tea Recipes Iced tea is available in bottles, already made, just like juices and sodas. Also, it can be bought as a powder, for you to prepare it at home. However, you can use a more classic recipe to make your own iced tea. It’ll also be a lot more natural and, therefore, better for your health. For about two liters of iced tea, you mostly need cold water and tea leaves. Heat about 4 cups of cold water, add about two tablespoons of dried tea leaves and let them steep according to the time required by the types of leaves you use. Once the steeping time is done, strain to remove the leaves and pour the ‘tea’ inside a pitcher filled with ice. Some recipes of unsweetened tea recommend you to let the steeping last for an hour under the sun, for example, or even overnight in the refrigerator. Iced Tea Flavors The iced tea recipe uses leaves of the classic types of tea, like green tea or black tea. This doesn’t mean you can’t flavor it to your liking. To sweeten the iced tea, you can use sugar or honey. You can also add fresh fruits, but also frozen fruits, which will help keep the tea cold. Herbs and spices can be used too: mint, sage, lemongrass, lavender, basil, and lemon balm, or cardamom, cinnamon, nutmeg, and ginger. Fruit juices or fruit purees make a good sweetener, too. Pros and cons of iced tea Prepared with fresh ingredients, iced tea can serve as a healthy beverage - definitely more natural than cold sodas. If you use honey or fruits to sweeten it instead of sugar, it’s even better for your health. You have to be careful with the amount of iced tea you drink, and how fast you drink it. If you know you’ve got throat problems, you might end up with a sore throat in the middle of summer. Also, be careful with the caffeine content it might have from the tea leaves you use. Tea leaves from the plant Camellia sinensis contain caffeine. If you know coffee’s not good for you, especially if you’ve got heart problems, you can use herbal leaves to make your iced tea.   Iced tea is the perfect choice for a healthy, refreshing beverage during hot summer days. Prepare it yourself at home and you’ll surely enjoy it!... all you need to know about iced tea!

Angiotensin-convertingenzyme (ace) Inhibitors

The ENZYME that converts angiotensin I to angiotensin II (see ANGIOTENSIN) is called angiotensin-converting enzyme. Angiotensin II controls the blood pressure and is the most potent endogenous pressor substance produced in the body; angiotensin I has no such pressor activity. Inhibition of the enzyme that converts angiotensin I to angiotensin II will thus have marked effects on lowering the blood pressure, and ACE inhibitors have a valuable role in treating heart failure when thiazides and beta blockers cannot be used or fail to work, especially after myocardial infarction (see HEART, DISEASES OF). Captopril was the ?rst ACE inhibitor to be synthesised: it reduces peripheral resistance by causing arteriolar dilatation and thus lowers blood pressure. Other drugs such as enalapril, lisinopril, cilazapril, quinapril and ramipril have since been developed. Some kidney disorders increase the production of angiotensin II and so cause HYPERTENSION.... angiotensin-convertingenzyme (ace) inhibitors

Boxing Injuries

Boxing injuries rank eighth in frequency among sports injuries. According to the Report on the Medical Aspects of Boxing issued by the Committee on Boxing of the Royal College of Physicians of London in 1969, of 224 ex-professional boxers examined, 37 showed evidence of brain damage and this was disabling in


The ?rst type of damage occurs as an acute episode in which one or more severe blows leads to loss of consciousness and occasionally to death. Death in the acute phase is usually due to intracranial haemorrhage and this carries a mortality of 45 per cent even with the sophisticated surgical techniques currently available. The second type of damage develops over a much longer period and is cumulative, leading to the atrophy of the cerebral cortex and brain stem. The repair processes of the brain are very limited and even after mild concussion it may suffer a small amount of permanent structural damage. Brain-scanning techniques now enable brain damage to be detected during life, and brain damage of the type previously associated with the punch-drunk syndrome is now being detected before obvious clinical signs have developed. Evidence of cerebral atrophy has been found in relatively young boxers including amateurs and those whose careers have been considered successful. The tragedy is that brain damage can only be detected after it has occurred. Many doctors are opposed to boxing, even with the present, more stringent medical precautions taken by those responsible for running the sport. Since the Royal College’s survey in 1969, the British Medical Association and other UK medical organisations have declared their opposition to boxing on medical grounds, as have medical organisations in several other countries.

In 1998, the Dutch Health Council recommended that professional boxing should be banned unless the rules are tightened. It claimed that chronic brain damage is seen in 40–80 per cent of boxers and that one in eight amateur bouts end with a concussed participant.

There is currently no legal basis on which to ban boxing in the UK, although it has been suggested that an injured boxer might one day sue a promoter. One correspondent to the British Medical Journal in 1998 suggested that since medical cover is a legal requirement at boxing promotions, the profession should consider if its members should withdraw participation.... boxing injuries

Brain Injuries

Most blows to the head cause no loss of consciousness and no brain injury. If someone is knocked out for a minute or two, there has been a brief disturbance of the brain cells (concussion); usually there are no after-effects. Most patients so affected leave hospital within 1–3 days, have no organic signs, and recover and return quickly to work without further complaints.

Severe head injuries cause unconsciousness for hours or many days, followed by loss of memory before and after that period of unconsciousness. The skull may be fractured; there may be ?ts in the ?rst week; and there may develop a blood clot in the brain (intracerebral haematoma) or within the membranes covering the brain (extradural and subdural haematomata). These clots compress the brain, and the pressure inside the skull – intracranial pressure – rises with urgent, life-threatening consequences. They are identi?ed by neurologists and neurosurgeons, con?rmed by brain scans (see COMPUTED TOMOGRAPHY; MRI), and require urgent surgical removal. Recovery may be complete, or in very severe cases can be marred by physical disabilities, EPILEPSY, and by changes in intelligence, rational judgement and behaviour. Symptoms generally improve in the ?rst two years.

A minority of those with minor head injuries have complaints and disabilities which seem disproportionate to the injury sustained. Referred to as the post-traumatic syndrome, this is not a diagnostic entity. The complaints are headaches, forgetfulness, irritability, slowness, poor concentration, fatigue, dizziness (usually not vertigo), intolerance of alcohol, light and noise, loss of interests and initiative, DEPRESSION, anxiety, and impaired LIBIDO. Reassurance and return to light work help these symptoms to disappear, in most cases within three months. Psychological illness and unresolved compensation-claims feature in many with implacable complaints.

Consequently, you will rejoice in the lovely cherry aroma of your amazingly enticing and enjoyable beverage. Health Benefits of Cherry Tea Cherry Tea is a beneficial fruity beverage with numerous health benefits. Cherry fruits are renowned for their delightfully refreshing flavour and delicious sweet taste, but they are also packed with nutrients, vitamins and minerals that essentially contribute to our wellbeing. These fruits are rich in antioxidants which protect our body from free radicals and thus lower the risk of cancer and various neurological diseases, but they also delay the aging process. Cherries also contain melatonin, an antioxidant with calming effects on the brain, which helps releave irritability, insomnia and headaches, thus improving the quality of sleep. The countless health benefits of cherry tea also include anti-inflammatory properties and could potentially prove effective against pain caused by diseases or injuries. Cherry fruits are low in calories, but they contain vitamin C which unfortunately entices you to consume approximately 180 calories more a day. This could possibly result in the accumulation of some extra weight if consumed for large periods of time. Therefore, adjust your dietary plan accordingly. Side effects of Cherry Tea Cherry Tea contains extracts from the cherries which can induce an allergic reaction to people sensitive to these fruits, but it is generally side-effect-free. You can enjoy a savory cup of cherry tea at any given time of the day in order to boost your overall energy level and metabolism.

Cochlear Implants

A cochlear implant is an electronic device, inserted under a general anaesthetic, which stimulates the auditory system, restoring partial hearing in profound sensory deafness. Although there are many types of cochlear implant, they all consist of a microphone, a signal processor, a signal coupler (transmitter and receiver), and an array of electrodes. Most are multi-channel implants. The microphone and signal processor are worn outside the body, like a conventional hearing aid: they receive sound and convert it into an electronic signal which is transmitted through the skin to the receiver. Here the signal is transmitted to the array of electrodes which stimulates the cochlear nerve. Although cochlear implants do not provide normal hearing, most profoundly deaf patients who receive a cochlear implant are able to detect a variety of sounds, including environmental sounds and speech. The duration of hearing-loss and age at implantation are among the many factors which in?uence the results (see DEAFNESS).... cochlear implants

Cox-2 Inhibitors

This stands for cyclo-oxygenase 2 inhibitors – a class of drugs used in treating ARTHRITIS – of which the most well-used is celecoxib. Their main claim is that they are less likely to cause gastrointestinal disturbance than NONSTEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDS). In 2001, the National Institute for Clinical Excellence (NICE) recommended that they should not be used routinely in rheumatoid arthritis or osteoarthritis but only in patients with a history of peptic ulcer or gastrointestinal bleeding. They should also be considered in persons over the age of 65 taking other drugs which could cause gastrointestinal bleeding, those who are very debilitated, and those who are taking maximum doses of NSAIDs. In 2005, rofecoxib was withdrawn because of concerns about cardiac side-effects.... cox-2 inhibitors

Importance: Common indigo or Indian indigo is a branching shrub which grows upto 2m high. Nili is a reputed drug produced from this plant which is used in ayurveda for the promotion of hair growth and it forms a major ingredient of preparations like nilibhringadi oil. This is the original source of natural indigo. Due to antitoxic property it is also a good remedy for poisons. According to Bhavaprakasa, nili is purgative in action, bitter, hot, cures giddiness, abdominal enlargement, vatarakta, gout and intestinal obstruction. The decoction or powder of the plant is used in whooping cough, bronchitis, palpitation of the heart, enlargement of the liver and spleen, dropsy, diseases of lungs and kidney, epilepsy and nervous disorders. A poultice of the leaves is recommended in skin diseases, piles, ulcer and haemorrhoids. A wine glass full juice of the leaves is administered in the morning with or without milk for three days to those who have been bitten by mad dogs. Root decoction is given in calculous diseases and used as an antidote to arsenic poisoning. The seed of the plant is powered and steeped in arrack or rum, yield a tincture, which is used to distroy lice. Indigo, the dye extracted from the leaves, is a soothing balm for burns and scalds, insect stings and animal bites. The synonyms visaghni and sodhani indicate the antitoxic and laxative properties of the drug nili, respectively (Aiyer and Kolammal, 1960).

Distribution: This plant is distributed in South and South East Asia, tropical Africa and is introduced in tropical America. In India, it is found almost throughout and cultivated in many parts.

Botany: Indigofera tinctoria Linn. syn. I. summatrana Gaertn, Pigmentum indicum belongs to Papilionaceae family. This is a branching shrub which grows upto 2m high. Stems and branches are green; branchlets silvery pubescent. Leaves are alternate, stipulate, imparipinnate and got 7-13 leaflets which are elliptic-oblong, membraneous,1.7x0.9cm, shortly mucronate, pale green or bluish. Flowers are small, rose-coloured in axillary racemes. Calyx 5-cleft, gamosepalous; corolla papilionaceous; stamens diadelphous; ovary sessile with a short incurved style ending in a capitate stigma. Pods are linear, cylindrical, 2-5cm long, deflexed having 8-12 seeds.

Agrotechnology: The Indian indigo requires good sunlight and grows well in hilly areas. This is usually propagated by seeds. Seeds are very small and the seed rate is 3kg/ha. Seeds require pretreatment for good germination as the seed coat is hard. Seeds are mixed with sand and ground gently to break the seed coat. An alternate method for enhancing germination is dipping the seeds in boiling water for a second. After pretreatment seeds are broadcasted. Broadcast the seeds preferably mixed with sand 2 or 3 times its volume to ensure uniform coverage. The seedbeds should be covered with straw and irrigated. Seeds germinate within 15 days. Seedlings are ready for transplanting after one month. For the land preparation, the soil is brought to fine tilth by ploughing 2 or 3 time s. Cattle manure should be applied at the rate of 10t/ha as basal dressing and incorporated into soil along with last ploughing. The best time for sowing is September-October. Weeding has to be done two times; 3 weeks after sowing and 6 weeks after sowing. Plants start flowering 2-3 months after sowing. Harvesting is done by cutting the plants at this time, at a height of about 10cm from ground level. Irrigate plants after harvest. Subsequent harvests can be made at 1.5-2 months interval. Four to five cuttings can be taken in an year depending on the growth. A few plants per plot are left without cutting to set seeds. Ripe pods are to be harvested in the early morning to prevent loss of seeds by shattering during harvest.

Properties and activity: A blue dyestuff is obtained from the indigofera which does not exist ready formed, but is produced during fermentation from another agent existing in the plant, known as indocan. Indocan is yellow amorphous of a nauseous bitter taste with an acid reaction, readily soluble in water, alcohol and ether. An artificial product indigotine is manufactured chemically and used as a substitute. Indirubin is another component of the plant.

The plant is deobstruent, alterative, antitoxic, antiasthmatic and antiepileptic. Aerial part is hypoglycaemic, CNS depressant and antitoxic. The leaves, flowers and tender shoots are considered to be cooling, demulcent and alterative. Leaf is antiinflammatory. Root and stem is laxative, expectorant, antitumourous, febrifuge, anticephalalgic, antidote for snake bite, anthelmintic and promotes growth of hair. Root is divertic. Indirubin is antineoplastic and has toxicity. Nili is antitoxic, purgative and laxative. Indigo is said to produce nausea and vomiting.... common indigo

Drug Interactions

Many patients are on several prescribed drugs, and numerous medicines are available over the counter, so the potential for drug interaction is large. A drug may interact with another by inhibiting its action, potentiating its action, or by simple summation of effects.

The interaction may take place:

(1) Prior to absorption or administration – for example, antacids bind tetracycline in the gut and prevent absorption.

(2) By interfering with protein binding – one drug may displace another from binding sites on plasma proteins. The action of the displaced drug will be increased because more drug is now available; for example, anticoagulants are displaced by analgesics.

(3) During metabolism or excretion of the drug – some drugs increase or decrease the activity of liver enzymes which metabolise drugs, thus affecting their rate of destruction; for example, barbiturates, nicotine, and alcohol all activate hepatic enzymes. Altering the pH of urine will affect the excretion of drugs via the kidney.

(4) At the drug receptor – one drug may displace another at the receptor, affecting its e?cacy or duration of action.... drug interactions

Electrical Injuries

These are usually caused by the passage through the body of an electric current of high voltage owing to accidental contact with a live wire or to a discharge of lightning. The general effects produced are included under the term electric shock, but vary greatly in degree. The local effects include spasmodic contraction of muscles, fracture of bones, and in severe cases more or less widespread destruction of tissues which may amount simply to burns of the skin or may include necrosis of masses of muscle and internal organs. Fright due to the unexpectedness of the shock, and pain due to the sudden cramp of muscles, are the most common symptoms and in most cases pass o? within a few minutes. In more severe cases – especially when the person has remained in contact with a live wire for some time, or has been unable to let go of the electrical contact owing to spasmodic contraction of the muscles – the effects are more pronounced and may include concussion or compression of the brain (see BRAIN, DISEASES OF). In still more severe cases, death may ensue either from paralysis of the respiration or stoppage of the heart’s action. If prompt measures are taken for treatment, the victim can often be resuscitated.

In Britain there are an average of 110 deaths a year from electrocution, half of these occurring in the home.

Treatment No electrical apparatus or switch should be touched by anyone who is in metallic contact with the ground, such as through a metal pipe, especially, for example, from a bath. The ?rst action is to break the current. This can sometimes be done by turning o? a switch. If the victim is grasping or in contact with a live wire, the contact may be severed with safety only by someone wearing rubber gloves or rubber boots; but as these are not likely to be immediately available, the rescuer’s hands may be protected by a thick wrapping of dry cloth, or the live wire may be hooked or pushed out of the way with a long wooden stick such as a broom-handle. If the injured person is unconscious, and especially if breathing has stopped, arti?cial respiration should be applied as described in APPENDIX 1: BASIC FIRST AID – Electrocution. When the patient begins to breathe again, he or she must be treated for shock and professional help obtained urgently.... electrical injuries

Fungal And Yeast Infections

These infections, also called mycoses (see MYCOSIS), are common and particularly affect the skin or mucosal membranes in, for example, the mouth, anus or vagina. Fungi consist of threadlike hyphae which form tangled masses or mycelia – common mould. In what is called dermatophyte (multicellular fungi) fungal infection of the hair, nails and SKIN, these hyphae invade the KERATIN. This is usually described as ‘RINGWORM’, although no worm is present and the infection does not necessarily occur in rings. PITYRIASIS versicolor and candidosis (monoliasis – see CANDIDA), called thrush when it occurs in the vulva, vagina and mouth, are caused by unicellular fungi which reproduce by budding and are called yeasts. Other fungi, such as ACTINOMYCOSIS, may cause deep systemic infection but this is uncommon, occurring mainly in patients with immunosuppressive disorders or those receiving prolonged treatment with ANTIBIOTICS.

Diagnosis and treatment Any person with isolated, itching, dry and scaling lesions of the skin with no obvious cause – for example, no history of eczema (see DERMATITIS) – should be suspected of having a fungal infection. Such lesions are usually asymmetrical. Skin scrapings or nail clippings should be sent for laboratory analysis. If the lesions have been treated with topical steroids they may appear untypical. Ultraviolet light ?ltered through glass (Wood’s light) will show up microsporum infections, which produce a green-blue ?uorescence.

Fungal infections used to be treated quite e?ectively with benzoic-acid compound ointment; it has now been superseded by new IMIDAZOLES preparations, such as CLOTRIMAZOLE, MICONAZOLE and terbina?ne creams. The POLYENES, NYSTATIN and AMPHOTERICIN B, are e?ective against yeast infections. If the skin is macerated it can be treated with magenta (Castellani’s) paint or dusting powder to dry it out.

Refractory fungal infection can be treated systematically provided that the diagnosis of the infection has been con?rmed. Terbina?ne, imidazoles and GRISEOFULVIN can all be taken by mouth and are e?ective for yeast infections. (Griseofulvin should not be taken in pregnancy or by people with liver failure or porphyria.) (See also FUNGUS; MICROBIOLOGY.)... fungal and yeast infections

Hospital-acquired Infection

An infection acquired by a patient while in hospital. Because of the high level of antibiotic use in hospitals, some bacteria become resistant

– for example, METHICILLIN-RESISTANT STAPHYLOCOCCUS AUREUS (MRSA). This makes hospital-acquired infections potentially dangerous and sometimes life-threatening, and is one of the developments that is prompting calls for greater care in the prescribing of antibiotics as well as higher standards of cleanliness.... hospital-acquired infection

Gender Identity Disorders

Gender identity is the inner sense of masculinity or femininity, and gender role is an individual’s public expression of being male, female, or a ‘mix’ (androgynous). Most people have no di?culty because their gender identity and role are congruous. A person with a gender identity disorder, however, has a con?ict between anatomical sex and gender identity.

Gender is determined by a combination of genetic and environmental factors, in which the in?uence of family upbringing is an important factor. When physical sexual characteristics are ambiguous, the child’s gender identity can usually be established if the child is reared as being clearly male or female. Should, however, the child be confused about its sexual identity, the uncertainty may continue into adult life. Transsexuals generally experience con?icts of identity in childhood, and such problems usually occur by the age of two years. In this type of identity disorder, which occurs in one in 30,000 male births and one in 100,000 female births, the person believes that he or she is the victim of a biological accident, trapped in a body different from what is felt to be his or her true sex.

Treatment is di?cult: psychotherapy and hormone treatment may help, but some affected individuals want surgery to change their body’s sexual organs to match their innately felt sexual gender. The decision to seek a physical sex change raises major social problems for individuals, and ethical problems for their doctors. Surgery, which is not always successful in the long term, requires careful assessment, discussion and planning. It is important to preclude mental illness; results in homosexual men who have undergone surgery are not usually satisfactory. Advice and information may be obtained from Gender Identity Consultancy Services.... gender identity disorders

Idiopathic Thrombocytopenic Purpura (itp)

Sometimes described as thrombocytopenia, this is an autoimmune disorder in which blood PLATELETS are destroyed. This disturbs the blood’s coagulative properties (see COAGULATION) and spontaneous bleeding (PURPURA) occurs into the skin. The disease may be acute in children but most recover without treatment. Adults may develop a more serious, chronic variety which requires treatment with CORTICOSTEROIDS and sometimes SPLENECTOMY. Should the disease persist despite these treatments, intravenous immunoglobulin or immunosuppressive drugs (see IMMUNOSUPPRESSION) are worth trying. Should the bleeding be or become life-threatening, concentrates of platelets should be administered.... idiopathic thrombocytopenic purpura (itp)

Immune Person/animal

A person or animal that possesses specific previous antibodies or cellular immunity as a result of previous infection or immunisation, or is so conditioned by such previous specific experience as to respond adequately with production of antibodies sufficient to prevent illness following exposure to the specific infectious agent of the disease. Immunity is relative; an ordinarily effective protection may be overwhelmed by an excessive dose of the infectious agent or an unusual portal of entry.... immune person/animal


The introduction of antigens (see ANTIGEN) into a body to produce IMMUNITY. The table above gives the immunisation programme recommended by the UK departments of health.... immunisation


Impaired IMMUNITY resulting from inherited or acquired abnormalities of the immune system. This leads to increased vulnerability to infection. Important inherited examples of immunode?ciency are defects in function of GRANULOCYTES and the COMPLEMENT SYSTEM. Common acquired forms of immunode?ciency are defective function of B-type lymphocytes and hence antibody de?ciency in ‘common variable hypogammaglobulinaemia’, and grossly de?cient CD4 T-cell function – malfunctioning T-type lymphocytes – in AIDS, secondary to HIV infection (see AIDS/HIV).... immunodeficiency


A specialist (medically or scienti?cally quali?ed) who practises or researches IMMUNOLOGY.... immunologist


An agent that stimulates either innate or acquired immunity. In the U.S., immunotherapy is relegated to experimental medicine, but a number of plant substances are used in Europe as immunostimulants. The presumption of immunostimulation is that you increase native resistance and let it run its course. American Standard Practice, with all good intentions, tends to aggressive procedures, and feels empowered only when intervening against, not with, physiologic responses. Medicine is the only approach to many problems, but in the U.S. we all tend to forget that our brand of standard practice is uniquely aggressive and invasive amongst the industrialized nations. There are other ways...which is presumably why you are using this glossary in the first place.... immunostimulant

For example, when one piece of bone is driven within another following a fracture, this is known as an impacted fracture; when a tooth is ?rmly lodged in its socket so that its eruption is prevented, this is known as dental impaction. Intractable constipation is termed faecal impaction.... impaction

Impatiens Balsamina


Family: Balsaminaceae.

Habitat: Cultivated in plains throughout India.

English: Garden Balsam. (Balsam Apple is not related to Impatiens. It is the fruit of Momordica balsamina.)

Ayurvedic: Tarini (provisional synonym).

Unani: Gul-menhdi.

Siddha/Tamil: Kasittumbai.

Action: Cathartic, diuretic, antirheumatic. Flowers—used in burns and scalds.

The plant is reported to contain cyanochroic constituents, antibacterial substances and an alkaloid. The seeds contain the triterpenoid hosenkol A, the first baccharance triterpenoid from natural source. The seeds also contain a protein-associated amyloid, galac- toxyloglucan and beta-sitosterol.

In China, the aerial parts are used for the treatment of articular rheumatism. In Korea, the plant is used for treating tuberculosis. In Brunei, a decoction of the root is given in irregular menstruation. In Japan, the juice, obtained from the white petals, is applied topically to treat several types of dermatitis, including urticaria.

The flowers contain flavonols, flavo- noid pigments, phenolic compounds and quinones.

An ethanolic extract (35%) of flowers shows significant anti-anaphylactic activity in mice.

Inadequate Intake Of Iron

The daily requirement of iron for an adult is 12 mg, and 15–20 mg for an adult woman during pregnancy. This is well covered by an ordinary diet, so that by itself it is not a common cause. But if there is a steady loss of blood, as a result of heavy menstrual loss or ‘bleeding piles’, the intake of iron in the diet may not be su?cient to maintain adequate formation of haemoglobin.

Symptoms These depend upon whether the anaemia is sudden in onset, as in severe haemorrhage, or gradual. In all cases, however, the striking sign is pallor, the depth of which depends upon the severity of the anaemia. The colour of the skin may be misleading, except in cases due to severe haemorrhage, as the skin of many Caucasian people is normally pale. The best guide is the colour of the internal lining of the eyelid. When the onset of the anaemia is sudden, the patient complains of weakness and giddiness, and loses consciousness if he or she tries to stand or sit up. The breathing is rapid and distressed, the pulse is rapid and the blood pressure is low. In chronic cases the tongue is often sore (GLOSSITIS), and the nails of the ?ngers may be brittle and concave instead of convex (koilonychia). In some cases, particularly in women, the Plummer-Vinson syndrome is present: this consists of di?culty in swallowing and may be accompanied by huskiness; in these cases glossitis is also present. There may be slight enlargement of the SPLEEN, and there is usually some diminution in gastric acidity.

CHANGES IN THE BLOOD The characteristic change is a diminution in both the haemoglobin and the red cell content of the blood. There is a relatively greater fall in the haemoglobin than in the red cell count. If the blood is examined under a microscope, the red cells are seen to be paler and smaller than normal. These small red cells are known as microcytes.

Treatment consists primarily of giving suf?cient iron by mouth to restore, and then maintain, a normal blood picture. The main iron preparation now used is ferrous sulphate, 200 mg, thrice daily after meals. When the blood picture has become normal, the dosage is gradually reduced. A preparation of iron is available which can be given intravenously, but this is only used in cases which do not respond to iron given by mouth, or in cases in which it is essential to obtain a quick response.

If, of course, there is haemorrhage, this must be arrested, and if the loss of blood has been severe it may be necessary to give a blood transfusion (see TRANSFUSION – Transfusion of blood). Care must be taken to ensure that the patient is having an adequate diet. If there is any underlying metabolic, oncological, toxic or infective condition, this, of course, must be adequately treated after appropriate investigations.

Megaloblastic hyperchromic anaemia There are various forms of anaemia of this type, such as those due to nutritional de?ciencies, but the most important is that known as pernicious anaemia.

PERNICIOUS ANAEMIA An autoimmune disease in which sensitised lymphocytes (see LYMPHOCYTE) destroy the PARIETAL cells of the stomach. These cells normally produce INTRINSIC FACTOR, the carrier protein for vitamin B12 (see APPENDIX 5: VITAMINS) that permits its absorption in the terminal part of the ILEUM. Lack of the factor prevents vitamin B12 absorption and this causes macrocytic (or megaloblastic) anaemia. The disorder can affect men and women, usually those over the age of 40; onset is insidious so it may be well advanced before medical advice is sought. The skin and MUCOSA become pale, the tongue is smooth and atrophic and is accompanied by CHEILOSIS. Peripheral NEUROPATHY is often present, resulting in PARAESTHESIA and numbness and sometimes ATAXIA. A rare complication is subacute combined degeneration of the SPINAL CORD.

In 1926 two Americans, G R Minot and W P Murphy, discovered that pernicious anaemia, a previously fatal condition, responded to treatment with liver which provides the absent intrinsic factor. Normal development requires a substance known as extrinsic factor, and this depends on the presence of intrinsic factor for its absorption from the gut. The disease is characterised in the blood by abnormally large red cells (macrocytes) which vary in shape and size, while the number of white cells (LEUCOCYTES) diminishes. A key diagnostic ?nd is the presence of cells in the BONE MARROW.

Treatment consists of injections of vitamin B12 in the form of hydroxocobalamin which must be continued for life.

Aplastic anaemia is a disease in which the red blood corpuscles are very greatly reduced, and in which no attempt appears to be made in the bone marrow towards their regeneration. It is more accurately called hypoplastic anaemia as the degree of impairment of bone-marrow function is rarely complete. The cause in many cases is not known, but in rather less than half the cases the condition is due to some toxic substance, such as benzol or certain drugs, or ionising radiations. The patient becomes very pale, with a tendency to haemorrhages under the skin and mucous membranes, and the temperature may at times be raised. The red blood corpuscles diminish steadily in numbers. Treatment consists primarily of regular blood transfusions. Although the disease is often fatal, the outlook has improved in recent years: around 25 per cent of patients recover when adequately treated, and others survive for several years. In severe cases promising results are being reported from the use of bone-marrow transplantation.

Haemolytic anaemia results from the excessive destruction, or HAEMOLYSIS, of the red blood cells. This may be the result of undue fragility of the red blood cells, when the condition is known as congenital haemolytic anaemia, or of acholuric JAUNDICE.

Sickle-cell anaemia A form of anaemia characteristically found in people of African descent, so-called because of the sickle shape of the red blood cells. It is caused by the presence of the abnormal HAEMOGLOBIN, haemoglobin S, due to AMINO ACID substitutions in their polypeptide chains, re?ecting a genetic mutation. Deoxygenation of haemoglobin S leads to sickling, which increases the blood viscosity and tends to obstruct ?ow, thereby increasing the sickling of other cells. THROMBOSIS and areas of tissue INFARCTION may follow, causing severe pain, swelling and tenderness. The resulting sickle cells are more fragile than normal red blood cells, and have a shorter life span, hence the anaemia. Advice is obtainable from the Sickle Cell Society.... inadequate intake of iron

Indian Bdellium

Commiphora mukul


San: Gugulu, Mahisaksah, Koushikaha, Devadhupa

Hin: Gugal Mal:Gulgulu Tam,

Tel: Gukkulu

Kan: Guggul

Ben: Guggul

Importance: Indian bdellium is a small, armed, deciduous tree from the bark of which gets an aromatic gum resin, the ‘Guggul’ of commerce. It is a versatile indigenous drug claimed by ayurvedists to be highly effective in the treatment of rheumatism, obesity, neurological and urinary disorders, tonsillitis, arthritis and a few other diseases. The fumes from burning guggul are recommended in hay- fever, chronic bronchitis and phytises.

The price of guggulu gum has increased ten fold in ten years or so, indicating the increase in its use as well as decrease in natural plant stand. It has been listed as a threatened plant by Botanical Survey of India (Dalal, 1995) and is included in the Red Data Book (IUCN) and over exploited species in the country (Billare,1989).

Distribution: The center of origin of Commiphora spp. is believed to be Africa and Asia. It is a widely adapted plant well distributed in arid regions of Africa (Somalia, Kenya and Ethiopia in north east and Madagascar, Zimbabwe, Botswana, Zaire in south west Africa), Arabian peninsula (Yemen, Saudi Arabia and Oman). Different species of Commiphora are distributed in Rajasthan, Gujarat, Maharashtra and Karnataka states of India and Sind and Baluchistan provinces of Pakistan (Tajuddin et al, 1994). In India, the main commercial source of gum guggul is Rajasthan and Gujarat.

Botany: The genus Commiphora of family Burseraceae comprises about 185 species. Most of them occur in Africa, Saudi Arabia and adjoining countries. In India only four species have been reported. They are C. mukul(Hook. ex Stocks) Engl. syn. Balsamodendron mukul (Hook. ex Stocks), C. wightii (Arnott) Bhandari, C.stocksiana Engl., C. berryi and C.agallocha Engl.

In early studies about the flora of India, the ‘guggul’ plant was known as Commiphora mukul(Hook. ex Stocks) Engl. or Balsamodendron mukul (Hook. ex Stocks). It was renamed as C. roxburghii by Santapau in 1962. According to Bhandari the correct Latin name of the species is C. wightii(Arnott) Bhandari, since the specific name ‘wightii’ was published in 1839, prior to ‘roxburghi’ in 1848 (Dalal and Patel, 1995).

C. mukul is a small tree upto 3-4m height with spinescent branching. Stem is brownish or pale yellow with ash colored bark peeling off in flakes. Young parts are glandular and pubescent. Leaves are alternate, 1-3 foliate, obovate, leathery and serrate (sometimes only towards the apex). Lateral leaflets when present only less than half the size of the terminal ones. Flowers small, brownish red, with short pedicel seen in fascicles of 2-3. Calyx campanulate, glandular, hairy and 4-5 lobed. Corolla with brownish red, broadly linear petals reflexed at apex. Stamens 8-10, alternatively long and short. Ovary oblong, ovoid and stigma bifid. Fruit is a drupe and red when ripe, ovate in shape with 2-3 celled stones. The chromosome number 2n= 26 (Warrier et al, 1994; Tajuddin et al, 1994).

Agrotechnology: Guggal being a plant of arid zone thrives well in arid- subtropical to tropical climate.

The rainfall may average between 100mm and 500mm while air temperature may vary between 40 C in summer and 3 C during winter. Maximum relative humidity prevails during rainy season (83% in the morning and 48% in the evening).Wind velocity remains between 20-25 km/hour during the year is good. Though they prefer hard gypseous soil, they are found over sandy to silt loam soils, poor in organic matter but rich in several other minerals in arid tracks of western India (Tajuddin et al, 1994).

Plants are propagated both by vegetatively and seeds. Plants are best raised from stem cuttings from the semi woody (old) branch. For this purpose one metre long woody stem of 10mm thickness is selected and the cut end is treated with IBA or NAA and planted in a well manured nursery bed during June-July months; the beds should be given light irrigation periodically. The cuttings initiate sprouting in 10-15 days and grow into good green sprout in 10-12 months. These rooted plants are suitable for planting in the fields during the next rainy season. The cuttings give 80-94% sprouting usually. Air layering has also been successfully attempted and protocol for meristem culture is available in literature. Seed germination is very poor (5%) but seedling produce healthier plants which withstand high velocity winds.

The rooted cuttings are planted in a well laid-out fields during rainy season. Pits of size 0.5m cube are dug out at 3-4 m spacing in rows and given FYM and filler soil of the pit is treated with BHC (10%) or aldrin (5%) to protect the new plants from white ants damage. Fertilizer trials have shown little response except due to low level of N fertilization. Removal of side branches and low level of irrigation supports a good growth of these plants. The plantation does not require much weeding and hoeing. But the soil around the bushes be pulverised twice in a year to increase their growth and given urea or ammonium sulphate at 25- 50g per bush at a time and irrigated. Dalal et al (1989) reported that cercospora leaf spot was noticed on all the cultures. Bacterial leaf blight was also noticed to attack the cultures. A leaf eating caterpillar (Euproctis lanata Walker) attack guggal, though not seriously. White fly (Bemisia tabaci) is observed to suck sap of leaves and such leaves become yellowish and eventually drop. These can be effectively controlled by using suitable insecticide.

Stem or branch having maximum diameter of about 5cm at place of incision, irrespective of age is tapped. The necrotic patch on the bark is peeled off with a sharp knife and Bordeaux paste is applied to the exposed (peeled off) surface of the stem or branch. A prick chisel of about 3cm width is used to make bark- deep incisions and while incising the bark, the chisel is held at an acute angle so that scooped suspension present on the body of the chisel flows towards the blade of the chisel and a small quantity of suspension flows inside the incised bark. If tapping is successful, gum exudation ensures after about 15-20 days from the date of incision and continues for nearly 30-45 days. The exuded gum slides down the stem or branch, and eventually drops on the ground and gets soiled. A piece of polythene sheet can be pouched around the place of incision to collect gum. Alternatively, a polythene sheet can be spread on the ground to collect exuded gum. A maximum of about 500g of gum has been obtained from a plant (Dalal, 1995).

Post harvest technology: The best grade of guggul is collected from thick branches of tree. These lumps of guggul are translucent. Second grade guggul is usually mixed with bark, sand and is dull coloured guggul. Third grade guggul is usually collected from the ground which is mixed with sand, stones and other foreign matter. The final grading is done after getting cleansed material. Inferior grades are improved by sprinkling castor oil over the heaps of the guggul which impart it a shining appearance (Tajuddin et al, 1994).

Properties and activity: The gum resin contains guggul sterons Z and E, guggul sterols I-V, two diterpenoids- a terpene hydrocarbon named cembreneA and a diterpene alcohol- mukulol, -camphrone and cembrene, long chain aliphatic tetrols- octadecan-1,2,3,4-tetrol, eicosan-1,2,3,4-tetrol and nonadecan-1,2,3,4-tetrol. Major components from essential oil of gum resin are myrcene and dimyrcene. Plant without leaves, flowers and fruits contains myricyl alcohol, -sitosterol and fifteen aminoacids. Flowers contain quercetin and its glycosides as major flavonoid components, other constituents being ellagic acid and pelargonidin glucoside (Patil et al, 1972; Purushothaman and Chandrasekharan, 1976).

The gum resin is bitter, acrid, astringent, thermogenic, aromatic, expectorant, digestive, anthelmintic, antiinflammatory, anodyne, antiseptic, demulcent, carminative, emmenagogue, haematinic, diuretic, lithontriptic, rejuvenating and general tonic.

Hin: Abhuyicampa

Mal: Chengazhuneerkizhengu, Chengazhuneerkuva

Tam: Nerppicin

Kan: Nelasampiga

Tel: Bhucampakamu, Kondakaluva Mar: Bhuichampa

Importance: The tubers of Indian crocus are widely used as a local application for tumours, swellings and wounds. They are also given in gastric complaints. They help to remove blood clots and other purulent matter in the body. The juice of the tubers is given in dropsical affections of hands and feet, and of effusions in joints. The juice causes salivation and vomiting. In Ayurveda, the improvement formulations using the herb are Chyavanaprasam, Asokarishtam, Baladthatryaditailam, Kalyanakaghritham, etc. The drug “HALLAKAM” prepared from this is in popular use in the form of powder or as an ointment application to wounds and bruises to reduce swellings. It also improves complexion and cures burning sensation, mental disorders and insomnia (NRF, 1998; Sivarajan et al, 1994).

Distribution: The plant is distributed in the tropics and sub-tropics of Asia and Africa. The plant grows wild in shaded areas which are wet or humid, especially in forests in South India. It grows in gardens and is known for their beautiful flowers and foliage. It is also cultivated as an intercrop with other commercial crops.

Botany: Kaempferia rotunda Linn. belonging to the family Zingiberaceae is an aromatic herb with tuberous root-stalk and very short stem. Leaves are simple, few, erect, oblong or ovate- lanceolate, acuminate, 30cm long, 10cm wide, variegated green above and tinged with purple below. Flowers are fragrant, white, tip purple or lilac arranged in crowded spikes opening successively. The plant produces a subglobose tuberous rhizome from which many roots bearing small oblong or rounded tubers arise (Warrier et al, 1995).

Agrotechnology: The plant is a tropical one adapted for tropical climate. Rich loamy soil having good drainage is ideal for the plant. Laterite soil with heavy organic manure application is also well suited. Planting is done in May-June with the receipt of 4 or 5 pre-monsoon showers. The seed rate recommended is 1500-2000kg rhizomes/ha. Whole or split rhizome with one healthy sprout is the planting material. Well developed healthy and disease free rhizomes with the attached root tubers are selected for planting. Rhizomes can be stored in cool dry place or pits dug under shade plastered with mud or cowdung. The field is ploughed to a fine tilth, mixed with organic manure at 10-15t/ha. Seed beds are prepared at a size of 1m breadth and convenient length. Pits are made at 20cm spacing in which 5cm long pieces of rhizomes are planted. Pits are covered with organic manure. They are then covered with rotten straw or leaves. Apply FYM or compost as basal dose at 20 t/ha either by broadcasting and ploughing or by covering the seed in pits after planting. Apply fertilisers at the rate of 50:50:50 kg N, P2O5 and K2O/ha at the time of first and second weeding. After planting, mulch the beds with dry or green leaves at 15 t/ha. During heavy rainy months, leaf rot disease occurs which can be controlled by drenching 1% Bordeaux mixture. The crop can be harvested after 7 months maturity. Drying up of the leaves is the indication of maturity. Harvest the crop carefully without cutting the rhizome, remove dried leaves and roots. Wash the rhizome in water. They are stored in moisture-proof sheds. Prolonged storage may cause insect and fungus attack (Prasad et al, 1997).

Properties and activity: The tubers contain crotepoxide and -sitosterol. Tuber contains essential oil which give a compound with melting point 149oC which yielded benzoic acid on hydrolysis.

Indian Ginseng

Withania somnifera


San: Aswagandha, Varahakarni

Hin: Asgandh, Punir Mal: Amukkuram

Tam: Amukkira

Tel: Vajigandha

Mar: Askandha

Guj: Ghoda

Kan: Viremaddinagaddi

Importance: Indian ginseng or Winter cherry is an erect branching perennial undershrub which is considered to be one of the best rejuvenating agents in Ayurveda. Its roots, leaves and seeds are used in Ayurvedic and Unani medicines, to combat diseases ranging from tuberculosis to arthritis. The pharmacological activity of the plant is attributed to the presence of several alkaloids and withaniols. Roots are prescribed in medicines for hiccup, several female disorders, bronchitis, rheumatism, dropsy, stomach and lung inflammations and skin diseases. Its roots and paste of green leaves are used to relieve joint pains and inflammation. It is also an ingredient of medicaments prescribed for curing disability and sexual weakness in male. Leaves are used in eye diseases. Seeds are diuretic. It is a constituent of the herbal drug ‘Lactare’ which is a galactagogue.

Aswagandha was observed to increase cell-mediated immunity, prevent stress induced changes in adrenal function and enhance protein synthesis. Milk fortified with it increases total proteins and body weight. It is a well known rejuvenating agent capable of imparting long life, youthful vigour and intellectual power. It improves physical strength and is prescribed in all cases of general debility. Aswagandha powder (6-12g) twice a day along with honey and ghee is advised for tuberculosis in Sushruta Samhita. It also provides sound sleep (Prakash, 1997).

Distribution: Aswagandha is believed to have oriental origin. It is found wild in the forests of Mandsaur and Bastar in Mandhya Pradesh, the foot hills of Punjab, Himachal Pradesh, Uttar Pradesh and western Himalayas in India. It is also found wild in the Mediterranean region in North America. In India it is cultivated in Madhya Pradesh, Rajastan and other drier parts of the country.

Botany: Aswagandha belongs to the genus Withania and family Solanaceae. Two species, viz, W. coagulans Dunal and W. somnifera Dunal are found in India. W. coagulans is a rigid grey under shrub of 60-120cm high. W. somnifera is erect, evergreen, tomentose shrub, 30-75cm in height. Roots are stout, fleshy, cylindrical, 1-2cm in diameter and whitish brown in colour. Leaves are simple, ovate, glabrous and opposite. Flowers are bisexual, inconspicuous, greenish or dull yellow in colour born on axillary umbellate cymes, comprising 5 sepals, petals and stamens each; the two celled ovary has a single style and a bilobed stigma. The petals are united and tubular. The stamens are attached to the corolla tube and bear erect anthers which form a close column or cone around the style. Pollen production is poor. The fruit is a small berry, globose, orange red when mature and is enclosed in persistent calyx. The seeds are small, flat, yellow and reniform in shape and very light in weight. The chromosome number 2n = 48.

The cultivated plants have sizable differences from the wild forms not only in their morphological characters but also in the therapeutical action, though the alkaloids present are the same in both (Kaul, 1957). Some botanists, therefore, described the cultivated plant distinct from wild taxa and have coined a new name W. aswagandha (Kaul, 1957) which is contested by Atal and Schwarting (1961).

Agrotechnology: Asgandh is a tropical crop growing well under dry climate. The areas receiving 600 to 750mm rainfall is best suited to this crop. Rainy season crop requires relatively dry season and the roots are fully developed when 1-2 late winter rains are received. Sandy loam or light red soils having a pH of 7.5- 8.0 with good drainage are suitable for its cultivation. It is usually cultivated on poor and marginal soils. Withania is propagated through seeds. It is a late kharif crop and planting is done in August. Seeds are either broadcast-sown or seedlings are raised in nursery and then transplanted. Seed rate is 10-12 kg/ha for broadcasting and 5kg/ha for transplanting. In direct sown crop plants are thinned and gap filling is done 25-30 days after sowing. Seeds should be treated with Dithane M-45 at 3g/kg of seeds before sowing. Seeds are sown in the nursery just before the onset of rainy season and covered with light soil. Seeds germinate in 6-7 days. When seedlings are six weeks old they are transplanted at 60cm in furrows taken 60cm apart. The crop is mainly grown as a rainfed crop on residual fertility and no manure or fertilizers are applied to this crop generally. However, application of organic manure is beneficial for realizing better yields. It is not a fertilizer responsive crop. One hand weeding 25-30 days after sowing helps to control weeds effectively. No serious pest is reported in this crop. Diseases like seedling rot and blight are observed. Seedling mortality becomes serious under high temperature and humid conditions. The disease can be minimized by use of disease free seeds and treatment with thiram or deltan at 3-4g/kg seed before sowing. Further, use of crop rotation, timely sowing and keeping field well drained also protect the crop. Spraying with 0.3% fytolan, dithane Z-78 or dithane M-45 will help controlling the disease incidence. Spraying is repeated at 15 days interval if the disease persists. Aswagandha is a crop of 150-170 days duration. The maturity of the crop is judged by the drying of the leaves and reddening of berries. Harvesting usually starts from January and continues till March. Roots, leaves and seeds are the economical parts. The entire plant is uprooted for roots, which are separated from the aerial parts. The berries are plucked from dried plants and are threshed to obtain the seeds. The yield is 400-500kg of dry roots and 50-75kg seeds per hectare.

Post harvest technology: The roots are separated from the plant by cutting the stem 1-2cm above the crown.

Roots are then cut into small pieces of 7-10cm to facilitate drying. Occasionally, the roots are dried as a whole. The dried roots are cleaned, trimmed, graded, packed and marketed. Roots are carefully hand sorted into the following four grades.

Grade A: Root pieces 7cm long, 1-1.5cm diameter, brittle, solid, and pure white from outside.

Grade B: Root pieces 5cm long, 1cm diameter, brittle, solid and white from outside.

Grade C: Root pieces 3-4cm long, less than 1cm diameter and solid. Lower grade: Root pieces smaller, hollow and yellowish from outside.

Properties and activity: Aswagandha roots contain alkaloids, starch, reducing sugar, hentriacontane, glycosides, dulcital, withaniol acid and a neutral compound. Wide variation (0.13-0.31%) is observed in alkaloid content. Majumdar (1955) isolated 8 amorphous bases such as withanine, somniferine, somniferinine, somnine, withananine, withananinine, pseudowithanine and withasomnine. Other alkaloids reported are nicotine, tropine, pseudotropine, 3, -tigloyloxytropane, choline, cuscudohygrine, anaferine, anahygrine and others. Free aminoacids in the roots include aspartic acid, glycine, tyrosine, alanine, proline, tryptophan, glutamic acid and cystine. Leaves contain 12 withanolides, alkaloids, glycosides, glucose and free amino acids. Berries contain a milk coagulating enzyme, two esterases, free amino acids, fatty oil, essential oil and alkaloids. Methods for alkaloid’s analysis in Asgandh roots have also been reported (Majumdar, 1955; Mishra, 1989; Maheshwari, 1989). Withania roots are astringent, bitter, acrid, somniferous, thermogenic, stimulant, aphrodisiac, diuretic and tonic. Leaf is antibiotic, antitumourous, antihepatotoxic and antiinflammatory. Seed is milk coagulating, hypnotic and diuretic.... indian ginseng

Kas: Aonla

Importance: Indian gooseberry or emblic myrobalan is a medium sized tree the fruit of which is used in many Ayurvedic preparations from time immemorial. It is useful in haemorrhage, leucorrhaea, menorrhagia, diarrhoea and dysentery. In combination with iron, it is useful for anaemia, jaundice and dyspepsia. It goes in combination in the preparation of triphala, arishta, rasayan, churna and chyavanaprash. Sanjivani pills made with other ingredients is used in typhoid, snake-bite and cholera. The green fruits are made into pickles and preserves to stimulate appetite. Seed is used in asthma, bronchitis and biliousness. Tender shoots taken with butter milk cures indigestion and diarrhoea. Leaves are also useful in conjunctivitis, inflammation, dyspepsia and dysentery. The bark is useful in gonorrhoea, jaundice, diarrhoea and myalgia. The root bark is astringent and is useful in ulcerative stomatitis and gastrohelcosis. Liquor fermented from fruit is good for indigestion, anaemia, jaundice, heart complaints, cold to the nose and for promoting urination. The dried fruits have good effect on hair hygiene and used as ingredient in shampoo and hair oil. The fruit is a very rich source of Vitamin C (600mg/100g) and is used in preserves as a nutritive tonic in general weakness (Dey, 1980).

Distribution: Indian gooseberry is found through out tropical and subtropical India, Sri Lanka and Malaca. It is abundant in deciduous forests of Madhya Pradesh and Darjeeling, Sikkim and Kashmir. It is also widely cultivated.

Botany: Phyllanthus emblica Linn. syn. Emblica officinalis Gaertn. belongs to Euphorbiaceae family. It is a small to medium sized deciduous tree growing up to 18m in height with thin light grey, bark exfoliating in small thin irregular flakes. Leaves are simple, many subsessile, closely set along the branchlets, distichous light green having the appearance of pinnate leaves. Flowers are greenish yellow in axillary fascicles, unisexual; males numerous on short slender pedicels; females few, subsessile; ovary 3-celled. Fruits are globose, 1-5cm in diameter, fleshy, pale yellow with 6 obscure vertical furrows enclosing 6 trigonous seeds in 2-seeded 3 crustaceous cocci. Two forms Amla are generally distinguished, the wild ones with smaller fruits and the cultivated ones with larger fruits and the latter are called ‘Banarasi’(Warrier et al, 1995).

Agrotechnology: Gooseberry is quite hardy and it prefers a warm dry climate. It needs good sunlight and rainfall. It can be grown in almost all types of soils, except very sandy type. A large fruited variety “Chambakad Large“ was located from the rain shadow region of the Western Ghats for cultivation in Kerala. Amla is usually propagated by seeds and rarely by root suckers and grafts. The seeds are enclosed in a hard seed coat which renders the germination difficult. The seeds can be extracted by keeping fully ripe fruits in the sun for 2-3 days till they split open releasing the seeds. Seeds are soaked in water for 3-4 hours and sown on previously prepared seed beds and irrigated. Excess irrigation and waterlogging are harmful. One month old seedlings can be transplanted to polythene bags and one year old seedlings can be planted in the main field with the onset of monsoon. Pits of size 50 cm3 are dug at 6-8m spacing and filled with a mixture of top soil and well rotten FYM and planting is done. Amla can also be planted as a windbreak around an orchard. Irrigation and weeding are required during the first year. Application of organic manure and mulching every year are highly beneficial. Chemical fertilisers are not usually applied. No serious pests or diseases are generally noted in this crop. Planted seedlings will commence bearing from the 10th year, while grafts after 3-4 years. The vegetative growth of the tree continues from April to July. Along with the new growth in the spring, flowering also commences. Fruits will mature by December-February. Fruit yield ranges from 30-50kg/tree/year when full grown (KAU,1993).

Properties and activity: Amla fruit is a rich natural source of vitamin C. It also contains cytokinin like substances identified as zeatin, zeatin riboside and zeatin nucleotide. The seeds yield 16% fixed oil, brownish yellow in colour. The plant contains tannins like glucogallia, corilagin, chebulagic acid and 3,6-digalloyl glucose. Root yields ellagic acid, lupeol, quercetin and - sitosterol (Thakur et al, 1989).

The fruit is diuretic, laxative, carminative, stomachic, astringent, antidiarrhoeal, antihaemorrhagic and antianaemic.... indian gooseberry

Importance: Indian Sarasaparilla or Country Sarasaparilla is a climbing slender plant with twining woody stems and a rust-coloured bark. The roots are useful in vitiated conditions of pitta, burning sensation, leucoderma, leprosy, skin diseases, pruritus, asthma, bronchitis, hyperdipsia, opthalmopathy, hemicrania, epileptic fits, dyspepsia, helminthiasis, diarrhoea, dysentery, haemorrhoids, strangury, leucorrhoea, syphilis, abcess, arthralgia, fever and general debility. The leaves are useful in vomiting, wounds and leucoderma. The stems are bitter, diaphoretic and laxative and are useful in inflammations, cerebropathy, hepatopathy, nephropathy, syphilis, metropathy, leucoderma, odontalgia, cough and asthma. The latex is good for conjunctivitis (Warrier et al, 1995). The important formulations using the drug are Saribadyasava, Pindataila, Vidaryadi lehya, Draksadi kasaya, Jatyadi ghrita, etc. (Sivarajan et al, 1994). The Hemidesmus root powdered and mixed with cow’s milk is given with much benefit in the case of strangury. In the form of syrup, it has demulcent and diuretic proportions. The root, roasted in plantain leaves, then beaten into a mass with cumin and sugar and mixed with ghee is a household remedy in genito-urinary diseases. The hot infusion of the root-bark with milk and sugar is a good alterative tonic especially for children in cases of chronic cough and diarrhoea (Nadkarni, 1998). It has been successfully used in the cure of venereal diseases where American Sarasaparilla (Aralia nudicaulis Linn.) has failed. Native doctors utilize it in nephritic complaints and for sore mouths of children (Grieve and Leyel, 1992).

Distribution: Hemidesmus is distributed throughout India, the Moluccas and Sri Lanka.

Botany: Hemidesmus indicus (Linn.) R. Br. syn. Periploca indica Linn. belongs to the family Asclepiadaceae. It is a perennial, slender, laticiferous, twining or prostrate, wiry shrub with woody rootstock and numerous slender, terete stems having thickened nodes. Leaves are simple, opposite, very variable from elliptic-oblong to linear-lanceolate, variegated with white above and silvery white and pubescent beneath. Flowers are greenish purple crowded in sub-sessile cymes in the opposite leaf-axils. Fruits are slender follicles, cylindrical, 10cm long, tapering to a point at the apex. Seeds are flattened, black, ovate-oblong and coma silvery white. The tuberous root is dark-brown, coma silvery white, tortuous with transversely cracked and longitudinally fissured bark. It has a strong central vasculature and a pleasant smell and taste (Warrier et al, 1995).

The Ayurvedic texts mention two varieties, viz. a krsna or black variety and a sveta or white variety (Aiyer, 1951) which together constitute the pair, Saribadvayam. The drug is known as Sariba. Svetasariba is H. indicus. Two plants, namely, Ichnocarpus fructescens (Apocynaceae) known as pal-valli in vernacular and Cryptolepis buchanani (Asclepidaceae) known as Katupalvalli (Rheeds, 1689) are equated with black variety or Krsnasariba (Chunekar, 1982; Sharma, 1983).

Agrotechnology: Hemidesmus is propagated through root cuttings. The root cuttings of length 3-5cm can be planted in polybags or in the field. They can be planted in flat beds or on ridges. Planting is done usually at a spacing of 50x20cm. Heavy application of organic manure is essential for good growth and root yield. Inorganic fertilizers are not usually applied. Frequent weeding and earthing up are required, as the plant is only slow growing. Provision of standards for twining will further improve the growth and yield of the plant.

Properties and activity: The twigs of the plant give a pregnane ester diglycoside named desinine. Roots give -sitosterol, 2-hydroxy-4-methoxy benzaldehyde, -amyrin, -amyrin and its acetate, hexatriacontane, lupeol octacosonate, lupeol and its acetate. Leaves, stem and root cultures give cholesterol, campesterol, -sitosterol and 16-dehydro-pregnenolone. Leaves and flowers also give flavonoid glycosides rutin, hyperoside and iso-quercitin (Husain et al,1992). “Hemidesmine”- a crystallizible principle is found in the volatile oil extracted from roots. Some suggest that it is only a stearoptene. It also contains some starch, saponin and in the suberous layer, tannic acid (Grieve and Leyel, 1992). The root is alterative, febrifuge, antileucorrhoeic, antisyphilitic, demulcent, diaphoretic, diuretic, tonic, galactogenic, antidote for scorpion-sting and snake-bite, antidiarrhoeal, blood purifier, antirheumatic and aperitive. Essential oil from root is anti-bacterial and the plant is antiviral (Husain et al, 1992).... indian sarasaparilla

Indigo Root Tea

Indigo Root Tea has been known for many years due to its antiseptic, astringent, antibiotic, emetic and antibacterial properties. Wild indigo (baptisia tinctoria) is a herbaceous annual plant that can be recognized by its branching stems and bluish green leaves. Its flowers usually bloom during May and September and they pose as bright yellow flowers. The constituents of Indigo Root Tea are flavonoids, isoflavones, alkaloids, coumarins and polysaccharides. They usually are active when the indigoo root is made into a decoction or used as a tincture. How To Make Indigo Root Tea If you want to make Indigo Root Tea, simply place a handful of indigo root in a cup of boiling water for about 10-15 minutes. After that, take it out of the heat and let it stand for about 3 minutes. Indigo Root Tea Benefits
  • Strenghtens the immune system.
  • Can speed recovery from the common cold.
  • Helps heal wounds and cuts.
  • Treats respiratory infections such as pharyngitis and tonsilitis.
  • Heals sore thorat.

Treatment The principles of management are supportive, with treatment of the underlying condition if that is possible. Oxygenation is improved by increasing the concentration of oxygen breathed in by the patient, usually with mechanical ventilation of the lungs, often using continuous positive airways pressure (CPAP). Attempts are made to reduce the formation of pulmonary oedema by careful management of how much ?uid is given to the patient (?uid balance). Infection is treated if it arises, as are the possible complications of prolonged ventilation with low lung compliance (e.g. PNEUMOTHORAX). There is some evidence that giving surfactant through a nebuliser or aerosol may help to improve lung e?ectiveness and reduce oedema. Some experimental evidence supports the use of free-radical scavengers and ANTIOXIDANTS, but these are not commonly used. Other techniques include the inhalation of NITRIC OXIDE (NO) to moderate vascular tone, and prone positioning to improve breathing. In severe cases, extracorporeal gas exchange has been advocated as a supportive measure until the lungs have healed enough for adequate gas exchange.

Industrial Injuries Benefit

The Industrial Injuries Scheme provides money for people who have suffered injury or illness because of their work. Bene?ts for employment-related disability (selfemployment is excluded) have been altered many times since they were introduced in 1948. There is now a mix of bene?ts, eligibility for which depends on several factors: the date, onset and type of disability are among the most important. ‘Industrial’ includes almost all forms of employment. In addition to accidents, there is a long list of prescribed industrial diseases ranging from BURSITIS, hearing loss, ASTHMA and viral HEPATITIS to unusual ones such as ORF. Psychological as well as physical disablement may attract bene?t, which is calculated on a percentage basis according to the extent of disability. The onus is on the individual to claim, and trade unions and representative organisations can advise on procedures. Injured employees should always report details of an accident to their employer and record it in the accident book promptly: even seemingly minor injuries may subsequently lead to some disability. Relevant information lea?ets are available – for example, from local bene?t agencies, local-authority advice centres and public libraries.... industrial injuries benefit

Infant Feeding

The newborn infant may be fed naturally from the breast, or arti?cially from a bottle.

Breast feeding Unless there is a genuine contraindication, every baby should be breast fed. The nutritional components of human milk are in the ideal proportions to promote the healthy growth of the human newborn. The mother’s milk, especially colostrum (the ?uid secreted before full lactation is established) contains immune cells and antibodies that increase the baby’s resistance to infection. From the mother’s point of view, breast feeding helps the womb to return to its normal size and helps her to lose excess body fat gained during pregnancy. Most importantly, breast feeding promotes intimate contact between mother and baby. A ?nal point to be borne in mind, however, is that drugs taken by a mother can be excreted in her milk. These include antibiotics, sedatives, tranquillisers, alcohol, nicotine and high-dose steroids or vitamins. Fortunately this is rarely a cause of trouble. (See also main entry on BREAST FEEDING.)

Arti?cial feeding Unmodi?ed cows’ milk is not a satisfactory food for the human newborn and may cause dangerous metabolic imbalance. If breast feeding is not feasible, one of the many commerciallly available formula milks should be used. Most of these are made from cows’ milk which has been modi?ed to re?ect the composition of human milk as closely as possible. For the rare infant who develops cows’-milk-protein intolerance, a milk based on soya-bean protein is indicated.

Feeding and weight gain The main guide as to whether an infant is being adequately fed is the weight. During the ?rst days of life a healthy infant loses weight, but should by the end of the second week return to birth weight. From then on, weight gain should be approximately 6oz. (170g) each week.

The timing of feeds reffects social convention rather than natural feeding patterns. Among the most primitive hunter-gatherer tribes of South America, babies are carried next to the breast and allowed to suckle at will. Fortunately for developed society, however, babies can be conditioned to intermittent feedings.

As the timing of breast feeding is ?exible – little or no preparation time being required – mothers can choose to feed their babies on demand. Far from spoiling the baby, demand feeding is likely to lead to a contented infant, the only necessary caution being that a crying baby is not always a hungry baby.

In general, a newborn will require feeding every two to four hours and, if well, is unlikely to sleep for more than six hours. After the ?rst months, a few lucky parents will ?nd their infant sleeping through the night.

Weaning Weaning on to solid foods is again a matter of individuality. Most babies will become dissatis?ed with a milk-only diet at around six months and develop enthusiasm for cereal-based weaning foods. Also at about this time they enjoy holding objects and transferring them to their mouths – the mouth being an important sense organ in infants. It is logical to include food items that they can hold, as this clearly brings the baby pleasure at this time. Introduction of solids before the age of four months is unusual and best avoided. The usual reason given for early weaning is that the baby appears hungry, but this is unlikely to be the case; crying due to COLIC, for example, is more probable. Some mothers take the baby’s desire to suck – say, on their ?nger – as a sign of hunger when this is, in fact, re?ex activity.

Delaying the start of weaning beyond nine months is nutritionally undesirable. As weaning progresses, the infant’s diet requires less milk. Once established on a varied solid diet, breast and formula milks can be safely replaced with cows’ milk. There is, however, no nutritional contraindication to continued breast feeding until the mother wishes to stop.

It is during weaning that infants realise they can arouse extreme maternal anxiety by refusing to eat. This can lead to force-feeding and battles of will which may culminate in a breakdown of the mother-child relationship. To avoid this, parents must resist the temptation to coax the child to eat. If the child refuses solid food, the meal should be taken away with a minimum of fuss. Children’s appetites re?ect their individual genetic structure and a well child will eat enough to grow and maintain satisfactory weight gain. If a child is not eating properly, weight gain will be inadequate over a prolonged period and an underlying illness is the most likely cause. Indeed, failure to thrive is the paediatrician’s best clue to chronic illness.

Advice on feeding Many sources of con?icting advice are available to new parents. It is impossible to satisfy everyone, and ultimately it is the well-being of the mother and infant and the closeness of their relationship that matter. In general, mothers should be wary of rigid advice. An experienced midwife, health visitor or well-baby-clinic nursing sister are among the most reliable sources of information.

Infant Mortality Rate (imr)

The number of deaths of infants under one year of age. The IMR in any given year is calculated as the number of deaths in the ?rst year of life in proportion to every 1,000 registered live births in that year. Along with PERINATAL MORTALITY, it is accepted as one of the most important criteria for assessing the health of the community and the standard of the social conditions of a country.

The improvement in the infant mortality rate has occurred mainly in the period from the second month of life. There has been much less improvement in the neonatal mortality rate – that is, the number of infants dying during the ?rst four weeks of life, expressed as a proportion of every 1,000 live births. During the ?rst week of life the main causes of death are asphyxia, prematurity, birth injuries and congenital abnormalities. After the ?rst week the main cause of death is infection.

Social conditions also play an important role in infant mortality. In England and Wales the infant mortality rate in 1930–32 was: Social Class I (professional), 32·7; Social Class III (skilled workers), 57·6; Social Class V (unskilled workers), 77·1. Many factors come into play in producing these social variations, but overcrowding is undoubtedly one of the most important.

1838–9 146 1950–52 30 1851–60 154 1960–62 22 1900–02 142 1970–72 18 1910–12 110 1980–82 12 1920–22 82 1990–92 7 1930–32 67 1996 6·2 1940–42 59 1999 5.8 2000 5.6

It is thus evident that for a reduction of the infant mortality rate to the minimum ?gure, the following conditions must be met. Mothers and potential mothers must be housed adequately in healthy surroundings, particularly with regard to safe water supplies and sewage disposal. The pregnant and nursing mother must be ensured an adequate diet. E?ective antenatal supervision must be available to every mother, as well as skilled supervision during labour (see PREGNANCY AND LABOUR). The newborn infant must be adequately nursed and fed and mothers encouraged to breast feed. Environmental and public-health measures must be taken to ensure adequate housing, a clean milk supply and full availability of medical care including such protective measures as IMMUNISATION against diphtheria, measles, poliomyelitis and whooping-cough. (See also PERINATAL MORTALITY.)... infant mortality rate (imr)


The reaction of the tissues to any injury, which may be the result of trauma, infection or chemicals. Local blood vessels dilate, thus increasing blood ?ow to the injured site. White blood cells invade the affected tissue, engul?ng bacteria or other foreign bodies; related cells consume any dead cells, thus producing PUS after which the site starts to heal. The patient feels pain and the affected tissue becomes hot, red and swollen, with its functioning affected. If the infection is severe it may persist locally – chronic in?ammation – or spread elsewhere in the body

Inflammatory Bowel Disease (ibd)

CROHN’S DISEASE and ULCERATIVE COLITIS are chronic in?ammatory diseases characterised by relapsing and remitting episodes over many years. The diseases are similar and are both classi?ed as IBD, but a signi?cant distinction is that Crohn’s disease can affect any part of the GASTROINTESTINAL TRACT from mouth to anus, whereas ulcerative colitis affects only the COLON. The incidence of IBD varies widely between countries, being rare in the developing world but much more common in westernised nations, where the incidence of Crohn’s disease is around 5–7 per 100,000 (and rising) and that of ulcerative colitis at a broadly stable 10 per 100,000. It is common for both disorders to develop in young adults, but there is a second spike of incidence in people in their 70s. Details about the two disorders are given under the individual entries elsewhere in the dictionary. In?ammatory bowel disease should not be confused with IRRITABLE BOWEL SYNDROME (IBS) which has some of the same symptoms of IBD but a di?erent cause and outcome.... inflammatory bowel disease (ibd)

Information Technology In Medicine

The advent of computing has had widespread effects in all areas of society, with medicine no exception. Computer systems are vital – as they are in any modern enterprise – for the administration of hospitals, general practices and health authorities, supporting payroll, ?nance, stock ordering and billing, resource and bed management, word-processing correspondence, laboratory-result reporting, appointment and record systems, and management audit.

The imaging systems of COMPUTED TOMOGRAPHY (CT) and magnetic resonance imaging (see MRI) have powerful computer techniques underlying them.

Computerised statistical analysis of study data, population databases and disease registries is now routine, leading to enhanced understanding of the interplay between diseases and the population. And the results of research, available on computerised indexes such as MEDLINE, can be obtained in searches that take only seconds, compared with the hours or days necessary to accomplish the same task with its paper incarnation, Index Medicus.

Medical informatics The direct computerisation of those activities which are uniquely medical – history-taking, examination, diagnosis and treatment – has proved an elusive goal, although one hotly pursued by doctors, engineers and scientists working in the discipline of medical informatics. Computer techniques have scored some successes: patients are, for example, more willing to be honest about taboo areas, such as their drug or alcohol consumption, or their sexual proclivities, with a computer than face to face with a clinician; however, the practice of taking a history remains the cornerstone of clinical practice. The examination of the patient is unlikely to be supplanted by technological means in the foreseeable future; visual and tactile recognition systems are still in their infancy. Skilled interpretation of the result by machine rather than the human mind seems equally as remote. Working its way slowly outwards from its starting point in mathematical logic, ARTIFICIAL INTELLIGENCE that in any way mimics its natural counterpart seems a distant prospect. Although there have been successes in computer-supported diagnosis in some specialised areas, such as the diagnosis of abdominal pain, workable systems that could supplant the mind of the generalist are still the dream of the many developers pursuing this goal, rather than a reality available to doctors in their consulting rooms now.

In therapeutics, computerised prescribing systems still require the doctor to make the decision about treatment, but facilitate the process of writing, issuing, and recording the prescription. In so doing, the system can provide automated checks, warning if necessary about allergies, potential drug interactions, or dosing errors. The built-in safety that this process o?ers is enhanced by the superior legibility of the script that ensues, reducing the potential for error when the medicine is dispensed by the nurse or the pharmacist.

Success in these individual applications continues to drive development, although the process has its critics, who are not slow to point to the lengthier consultations that arise when a computer is present in the consulting room and its distracting e?ect on communication with the patient.

Underlying these many software applications lies the ubiquitous personal computer – more powerful today than its mainframe predecessor of only 20 years ago – combined with networking technology that enables interconnection and the sharing of data. As in essence the doctor’s role involves the acquisition, manipulation and application of information – from the individual patient, and from the body of medical knowledge – great excitement surrounds the development of open systems that allow di?erent software and hardware platforms to interact. Many problems remain to be solved, not least the fact that for such systems to work, the whole organisation, and not just a few specialised individuals, must become computer literate. Such systems must be easy to learn to use, which requires an intuitive interface between user(s) and system(s) that is predictable and logical in its ordering and presentation of information.

Many other issues stand in the way of the development towards computerisation: standard systems of nomenclature for medical concepts have proved surprisingly di?cult to develop, but are crucial for successful information-sharing between users. Sharing information between existing legacy systems is a major challenge, often requiring customised software and extensive human intervention to enable the previous investments that an organisation has made in individual systems (e.g. laboratory-result reporting) to be integrated with newer technology. The beginnings of a global solution to this substantial obstacle to networking progress is in sight: the technology that enables the Internet – an international network of telephonically linked personal computers – also enables the establishment of intranets, in which individual servers (computers dedicated to serving information to other computers) act as repositories of ‘published’ data, which other users on the network may ‘browse’ as necessary in a client-server environment.

Systems that support this process are still in early stages of development, but the key conceptualisations are in place. Developments over the next 5–10 years will centre on the electronic patient record available to the clinician on an integrated clinical workstation. The clinical workstation – in essence a personal computer networked to the hospital or practice system – will enable the clinician to record clinical data and diagnoses, automate the ordering of investigations and the collection of the results, and facilitate referral and communication between the many professionals and departments involved in any individual patient’s care.

Once data is digitised – and that includes text, statistical tables, graphs, illustrations and radiological images, etc. – it may be as freely networked globally as locally. Consultations in which live video and sound transmissions are the bonds of the doctor-patient relationship (the techniques of telemedicine) are already reality, and have proved particularly convenient and cost-e?ective in linking the patient and the generalist to specialists in remote areas with low population density.

As with written personal medical records, con?dentiality of personal medical information on computers is essential. Computerised data are covered by the Data Protection Act 1984. This stipulates that data must:

be obtained and processed fairly and lawfully.

be held only for speci?ed lawful purposes.

•not be used in a manner incompatible with those purposes.

•only be recorded where necessary for these purposes.

be accurate and up to date.

not be stored longer than necessary.

be made available to the patient on request.

be protected by appropriate security and backup procedures. As these problems are solved, concerns about

privacy and con?dentiality arise. While paper records were often only con?dential by default, the potential for breaches of security in computerised networks is much graver. External breaches of the system by hackers are one serious concern, but internal breaches by authorised users making unauthorised use of the data are a much greater risk in practice. Governing network security so that clinical users have access on a need-to-know basis is a di?cult business: the software tools to enable this – encryption, and anonymisation (ensuring that clinical information about patients is anonymous to prevent con?dential information about them leaking out) of data collected for management and research processes – exist in the technical domain but remain a complex conundrum for solution in the real world.

The mushroom growth of websites covering myriad subjects has, of course, included health information. This ranges from clinical details on individual diseases to facts about medical organisations and institutes, patient support groups, etc. Some of this information contains comments and advice from orthodox and unorthodox practitioners. This open access to health information has been of great bene?t to patients and health professionals. But web browsers should be aware that not all the medical information, including suggested treatments, has been subject to PEER REVIEW, as is the case with most medical articles in recognised medical journals.... information technology in medicine

In?uenza is an acute infectious disease, characterised by a sudden onset, fever and generalised aches and pains. It usually occurs in epidemics and pandemics (see EPIDEMIC; PANDEMIC).

Cause The disease is caused by a VIRUS of the in?uenza group. There are at least three types of in?uenza virus, known respectively as A, B and

C. One of their most characteristic features is that infection with one type provides no protection against another. Equally important is the ease with which the in?uenza virus can change its character. It is these two characteristics which explain why one attack of in?uenza provides little, if any, protection against a subsequent attack, and why it is so di?cult to prepare an e?ective vaccine against the disease.

Epidemics of in?uenza due to virus A occur in Britain at two- to four-year intervals, and outbreaks of virus B in?uenza in less frequent cycles. Virus A in?uenza, for instance, was the prevalent infection in 1949, 1951, 1955 and 1956, whilst virus B in?uenza was epidemic in 1946, 1950, 1954 and, along with virus A, in 1958–59. The pandemic of 1957, which swept most of the world, although fortunately not in a severe form, was due to a new variant of virus A

– the so-called Asian virus – and it has been suggested that it was this variant that was responsible for the pandemics of 1889 and 1918. Since 1957, variants of virus A have been the predominating causes of in?uenza, accompanied on occasions by virus B.

In 1997 and 2004, outbreaks of Chinese avian in?uenza caused alarm. The in?uenza virus had apparently jumped species from birds

– probably chickens – to infect some people. Because no vaccine is available, there was a risk that this might start an epidemic.

Symptoms The incubation period of in?uenza A and B is 2–3 three days, and the disease is characterised by a sudden onset. In most cases this is followed by a short, sharp febrile illness of 2–4 days’ duration, associated with headache, prostration, generalised aching, and respiratory symptoms. In many cases the respiratory symptoms are restricted to the upper respiratory tract, and consist of signs of irritation of the nose, pharynx and larynx. There may be nosebleeds, and a dry, hacking cough is often a prominent and troublesome symptom. The fever is usually remittent and the temperature seldom exceeds 39·4 °C (103 °F), tending to ?uctuate between 38·3 and 39·4 °C (101 and 103 °F).

The most serious complication is infection of the lungs. This infection is usually due to organisms other than the in?uenza virus, and is a complication which can have serious results in elderly people.

The very severe form of ’?u which tends to occur during pandemics – and which was so common during the 1918–19 pandemic – is characterised by the rapid onset of bronchopneumonia and severe prostration. Because of the toxic e?ect on the heart, there is a particularly marked form of CYANOSIS, known as heliotrope cyanosis.

Convalescence following in?uenza tends to be prolonged. Even after an attack of average severity there tends to be a period of weakness and depression.

Treatment Expert opinion is still divided as to the real value of in?uenza vaccine in preventing the disease. Part of the trouble is that there is little value in giving any vaccine until it is known which particular virus is causing the infection. As this varies from winter to winter, and as the protection given by vaccine does not exceed one year, it is obviously not worthwhile attempting to vaccinate the whole community. The general rule therefore is that, unless there is any evidence that a particularly virulent type of virus is responsible, only the most vulnerable should be immunised – such as children in boarding schools, elderly people, and people who suffer from chronic bronchitis or asthma, chronic heart disease, renal failure, diabetes mellitus or immunosuppression (see under separate entries). In the face of an epidemic, people in key positions, such as doctors, nurses and those concerned with public safety, transport and other public utilities, should be vaccinated.

For an uncomplicated attack of in?uenza, treatment is symptomatic: that is, rest in bed, ANALGESICS to relieve the pain, sedatives, and a light diet. A linctus is useful to sooth a troublesome cough. The best analgesics are ASPIRIN or PARACETAMOL. None of the sulphonamides or the known antibiotics has any e?ect on the in?uenza virus; on the other hand, should the lungs become infected, antibiotics should be given immediately, because such an infection is usually due to other organisms. If possible, a sample of sputum should be examined to determine which organisms are responsible for the lung infection. The choice of antibiotic then depends upon which antibiotic the organism is most sensitive to.... influenza

Substances that can be inhaled into the body through the lungs. They may be delivered in traditional form dissolved in hot water and inhaled in the steam, or as an aerosol – a suspension of very small liquid or solid particles in the air. The latter are now usually delivered by devices in which the aerosol is kept under pressure in a small hand-held cylinder and delivered in required doses by a release mechanism.

Aerosols Asthmatic patients (see ASTHMA) ?nd aerosol devices to be of value in controlling their attacks. They provide an e?ective and convenient way of applying drugs directly to the bronchi, thus reducing the risks of unwanted effects accompanying SYSTEMIC therapy. BRONCHODILATOR aerosols contain either a beta-sympathomimetic agent or ipratropium bromide, which is an ANTICHOLINERGIC drug.

ISOPRENALINE was the ?rst compound to be widely used as an aerosol. It did however stimulate beta1 receptors in the heart as well as beta2 receptors in the bronchi, and so produced palpitations and even dangerous cardiac arrhythmias. Newer beta-adrenoceptor agonists are speci?c for the beta2 receptors and thus have a greater safety margin. They include SALBUTAMOL, TERBUTALINE, rimiterol, fenoterol and reproterol. Unwanted effects such as palpitations, tremor and restlessness are uncommon with these, more speci?c preparations. In patients who get insu?cient relief from the beta-adrenoreceptor agonist, the drug ipratropium bromide is worth adding. Salmeterol is a longer-acting choice for twice-daily administration: it is not intended for the relief of acute attacks, for which shorter-acting beta2 stimulants such as salbutamol should be used. Salmeterol should be added to existing corticosteroid therapy (see CORTICOSTEROIDS), rather than replacing it.

Patients must be taught carefully and observed while using their inhalers. It is important for them to realise that if the aerosol no longer gives more than slight transient relief, they should not increase the dose but seek medical help.... inhalants

Insecticide Resistance

The ability of a mosquito or other insect to survive contact with an insecticide in quantities that would normally kill a mosquito of the same species.... insecticide resistance


Substances which kill insects. Since the discovery of the insecticidal properties of DDT (see DICHLORODIPHENYL TRICHLOROETHANE) in 1940, a steady stream of new ones has been introduced. Their combined use has played an outstanding part in international public health campaigns, such as that of the World Health Organisation for the eradication of MALARIA.

Unfortunately, insects are liable to become resistant to insecticides, just as bacteria are liable to become resistant to antibiotics, and it is for this reason that so much research work is being devoted to the discovery of new ones. Researchers are also exploring new methods, such as releasing sexually sterile insects into the natural population.

The useful effects of insecticides must be set against increasing evidence that the indiscriminate use of some of these potent preparations is having an adverse e?ect – not only upon human beings, but also upon the ecosystems. Some, such as DDT – the use of which is now banned in the UK – are very stable compounds that enter the food chain and may ultimately be lethal to many animals, including birds and ?shes.... insecticides

Insulin-dependent Diabetes

Also called Juvenile-onset Diabetes, IDDM (Insulin-Dependent Diabetes) and Type I, it is a deficiency condition wherein the pancreas does not manufacture enough insulin or what it makes is formed improperly. It is usually inherited, although it may not surface until pregnancy, recovering from a life-threatening illness, boot camp or some other profound metabolic stress. It can have a not-hereditary source, since it seems to enigmatically follow after a viral disorder, and can occur spontaneously as an auto-immune condition. The percentage of folks with non-hereditary Type I diabetes is constantly increasing (or the other group is stable, but total numbers are increasing). Radical environmentalists and tree-hugging Gaiaist Pagans (I’m using the dialectic current to the pro-business backlash of the 1990s, when Green is out, and White-With-Green i$ in) claim this is another aspect of massive though subtle pollution from organochemical soup, which even some Real Doctors admit can cause increased auto-immune disease. (SOMETHING is causing it, at any rate, not simply cola drinks.)... insulin-dependent diabetes

Insulin-resistant Diabetes

Also called NIDDM (Non-Insulin-Dependent Diabetes) and Type II (Type II), it generally means you make your own insulin, you eat too many calories, your storage cells are filled and are taking no more fuel, your liver is stuck in a rut and keeps making more glucose out of everything you eat, your brain has no control over its consumption of glucose, but you have run out of places to put it so you pee it out, sweat it out, etc. etc. Also called Adult-onset Diabetes. An Internist may cry out in dismay at this simplification, and there are many subtle distinctions between the various types, as well as a number of distinct hereditary considerations. This, however, is the glossary of an herbalist, and this is the common picture of the Type II person that herbs will help.... insulin-resistant diabetes

Intelligence Quotient (iq)

This is the ratio between the mental age and chronological age multiplied by 100. Thus, if a boy of 10 years of age is found to have a mental age of 12 years, his IQ will be 120. On the other hand, if he is found to have a mental age of 8 years, his IQ will be 80.

The mental age is established by various tests, the most widely used of which are the Stanford-Binet Scale, the Wechsler Adult Intelligence Scale, and the Mill Hill Vocabulary Test.

Average intelligence is represented by an IQ of 100, with a range of 85 to 115. For practical purposes it is taken that the intellectual level reached by the average 15-year-old is indistinguishable from that of an adult.... intelligence quotient (iq)

Intensive Care Medicine

The origin of this important branch of medicine lies in the e?ective use of positive-pressure VENTILATION of the lungs to treat respiratory breathing failure in patients affected by POLIOMYELITIS in an outbreak of this potentially fatal disease in Denmark in 1952. Doctors reduced to 40 per cent, the 90 per cent mortality in patients receiving respiratory support with the traditional cuirass ventilator by using the new technique. They achieved this with a combination of manual positive-pressure ventilation provided through a TRACHEOSTOMY by medical students, and by looking after the patients in a speci?c area of the hospital, allowing the necessary sta?ng and equipment resources to be concentrated in one place.

The principle of one-to-one, 24-hours-a-day care for seriously ill patients has been widely adopted and developed for the initial treatment of many patients with life-threatening conditions. Thus, severely injured patients – those with serious medical conditions such as coronary thrombosis or who have undergone major surgery, and individuals suffering from potentially lethal toxic affects of poisons – are treated in an INTENSIVE THERAPY UNIT (ITU). Patients whose respiratory or circulatory systems have failed bene?t especially by being intensively treated. Most patients, especially post-operative ones, leave intensive care when their condition has been stabilised, usually after 24 or 48 hours. Some, however, need support for several weeks or even months. Since 1952, intensive medicine has become a valued specialty and a demanding one because of the range of skills needed by the doctors and nurses manning the ITUs.... intensive care medicine

Intensive Therapy Unit (itu)

Sometimes called an intensive care unit, this is a hospital unit in which seriously ill patients undergo resuscitation, monitoring and treatment. The units are sta?ed by doctors and nurses trained in INTENSIVE CARE MEDICINE, and patients receive 24-hour, one-to-one care with continuous monitoring of their condition with highly specialised electronic equipment that assesses vital body functions such as heart rate, respiration, blood pressure, temperature and blood chemistry. The average ITU in Britain has four to six beds, although units in larger hospitals, especially those dealing with tertiary-care referrals – for example, neurosurgical or organ transplant cases – are bigger, but 15 beds is usually the maximum. Annual throughput of patients ranges from fewer than 200 to more than 1,500 patients a year. As well as general ITUs, specialty units are provided for neonatal, paediatric, cardiothoracic and neurological patients in regional centres. The UK has 1–2 per cent of its hospital beds allocated to intensive care, a ?gure far below the average of 20 per cent provided in the United States. Thus patients undergoing intensive care in the UK are usually more seriously ill than those in the US. This is re?ected in the shortage of available ITU beds in Britain, especially in the winter.

Interleukins are lymphokines – that is, polypeptides produced by activated lymphocytes. They are involved in signalling between cells of the immune system (see IMMUNITY) and are released by several cell types, including lymphocytes. They interact to control the immune response of cells and also participate in HAEMOPOIESIS. There are seven varieties, interleukins 1 to 7. For example, interleukin 1 is produced as a result of in?ammation and stimulates the proliferation of T and B lymphocytes, enhancing the immune response by stimulating other lymphocytes and activating dormant T cells. Interleukin 2 has anti-cancer effects as it is able to activate T lymphocytes to become killer cells which destroy foreign antigens (see ANTIGEN) such as cancer cells, and this anti-cancer e?ect is being developed for clinical use. The remaining interleukins have a range of properties in cell growth and di?erentiation.... interleukins

Intermittent Positive Pressure (ipp)

The simplest form of intermittent positive-pressure ventilation is mouth-to-mouth resuscitation (see APPENDIX 1: BASIC FIRST AID) where an individual blows his or her own expired gases into the lungs of a non-breathing person via the mouth or nose. Similarly gas may be blown into the lungs via a face mask (or down an endotracheal tube) and a self-in?ating bag or an anaesthetic circuit containing a bag which is in?ated by the ?ow of fresh gas from an anaesthetic machine, gas cylinder, or piped supply. In all these examples expiration is passive.

For more prolonged arti?cial ventilation it is usual to use a specially designed machine or ventilator to perform the task. The ventilators used in operating theatres when patients are anaesthetised and paralysed are relatively simple devices.They often consist of bellows which ?ll with fresh gas and which are then mechanically emptied (by means of a weight, piston, or compressed gas) via a circuit or tubes attached to an endotracheal tube into the patient’s lungs. Adjustments can be made to the volume of fresh gas given with each breath and to the length of inspiration and expiration. Expiration is usually passive back to the atmosphere of the room via a scavenging system to avoid pollution.

In intensive-care units, where patients are not usually paralysed, the ventilators are more complex. They have electronic controls which allow the user to programme a variety of pressure waveforms for inspiration and expiration. There are also programmes that allow the patient to breathe between ventilated breaths or to trigger ventilated breaths, or inhibit ventilation when the patient is breathing.

Indications for arti?cial ventilation are when patients are unable to achieve adequate respiratory function even if they can still breathe on their own. This may be due to injury or disease of the central nervous, cardiovascular, or respiratory systems, or to drug overdose. Arti?cial ventilation is performed to allow time for healing and recovery. Sometimes the patient is able to breathe but it is considered advisable to control ventilation – for example, in severe head injury. Some operations require the patient to be paralysed for better or safer surgical access and this may require ventilation. With lung operations or very unwell patients, ventilation is also indicated.

Arti?cial ventilation usually bypasses the physiological mechanisms for humidi?cation of inspired air, so care must be taken to humidify inspired gases. It is important to monitor the e?cacy of ventilation – for example, by using blood gas measurement, pulse oximetry, and tidal carbon dioxide, and airways pressures.

Arti?cial ventilation is not without its hazards. The use of positive pressure raises the mean intrathoracic pressure. This can decrease venous return to the heart and cause a fall in CARDIAC OUTPUT and blood pressure. Positive-pressure ventilation may also cause PNEUMOTHORAX, but this is rare. While patients are ventilated, they are unable to breathe and so accidental disconnection from the ventilator may cause HYPOXIA and death.

Negative-pressure ventilation is seldom used nowadays. The chest or whole body, apart from the head, is placed inside an airtight box. A vacuum lowers the pressure within the box, causing the chest to expand. Air is drawn into the lungs through the mouth and nose. At the end of inspiration the vacuum is stopped, the pressure in the box returns to atmospheric, and the patient exhales passively. This is the principle of the ‘iron lung’ which saved many lives during the polio epidemics of the 1950s. These machines are cumbersome and make access to the patient di?cult. In addition, complex manipulation of ventilation is impossible.

Jet ventilation is a relatively modern form of ventilation which utilises very small tidal volumes (see LUNGS) from a high-pressure source at high frequencies (20–200/min). First developed by physiologists to produce low stable intrathoracic pressures whilst studying CAROTID BODY re?exes, it is sometimes now used in intensive-therapy units for patients who do not achieve adequate gas exchange with conventional ventilation. Its advantages are lower intrathoracic pressures (and therefore less risk of pneumothorax and impaired venous return) and better gas mixing within the lungs.... intermittent positive pressure (ipp)

Intermittent Self-catheterisation

Access to medical information via the Internet is widespread in some populations, often serving more patients than doctors. In addition to the huge variety of information available, patients can share experiences via electronic discussion groups, or obtain e-mail advice on a fee-for-service basis. Some professional organisations and journals provide free access to information, and the Internet can be a useful resource for medical practitioners and researchers. Concerns have arisen about the growth in electronic medical information: some believe that patients who have unlimited access to information via the Internet will be less likely to tolerate health-care rationing or will demand treatments that may be inappropriate in their individual circumstances. Other criticisms relate to the quality and accuracy of the information provided, potential breaches of patient CONFIDENTIALITY, and the risk of increased accusations of medical negligence (see also ETHICS).... internet

Intersexuality is a state of indeterminate sexuality of an individual, and may present in many di?erent forms. A characteristic is that only one type of gonad – testis or ovary – is present; in a HERMAPHRODITE both types are present. Intersexuality may be due to a fault in the genetic mechanism of sex determination as early as conception, or to later errors in sexual di?erentiation of the embryo and fetus, or after birth. Some cases may result from abnormal metabolism of the sex hormones, or may be drug-induced (for example, women given androgens [see ANDROGEN] or PROGESTERONE for repeated miscarriages may give birth to girls with some genital VIRILISATION). Abnormalities of the sex chromosomes may be associated with delayed (or failure of) sexual development, so that the individual shows some of the characteristics (often underdeveloped) of both sexes. Some of the more common presentations of the condition include HYPOGONADISM, CRYPTORCHIDISM, and primary AMENORRHOEA.

Intersexuality inevitably leads to considerable psychological disturbance as the child grows up. It is therefore important to reach an early decision as to the child’s sex – or at least, the sex that he or she is to be brought up as. Surgical or hormonal means should then be employed, when appropriate, to develop the attributes of that sex and diminish those of the other, together with psychological counselling.... intersexuality

Intestine, Diseases Of

The principal signs of trouble which has its origin in the intestine consist of pain somewhere about the abdomen, sometimes vomiting, and irregular bowel movements: constipation, diarrhoea or alternating bouts of these.


In?ammation of the outer surface is called peritonitis, a serious disease. That of the inner surface is known generally as enteritis, in?ammation of special parts receiving the names of colitis, appendicitis, irritable bowel syndrome (IBS) and in?ammatory bowel disease (IBD). Enteritis may form the chief symptom of certain infective diseases: for example in typhoid fever (see ENTERIC FEVER), cholera and dysentery. It may be acute, although not connected with any de?nite organism, when, if severe, it is a very serious condition, particularly in young children. Or it may be chronic, especially as the result of dysentery, and then constitutes a less serious if very troublesome complaint.

Perforation of the bowel may take place as the result either of injury or of disease. Stabs and other wounds which penetrate the abdomen may damage the bowel, and severe blows or crushes may tear it without any external wound. Ulceration, as in typhoid fever, or, more rarely, in TUBERCULOSIS, may cause an opening in the bowel-wall also. Again, when the bowel is greatly distended above an obstruction, faecal material may accumulate and produce ulcers, which rupture with the ordinary movements of the bowels. Whatever the cause, the symptoms are much the same.

Symptoms The contents of the bowel pass out through the perforation into the peritoneal cavity, and set up a general peritonitis. In consequence, the abdomen is painful, and after a few hours becomes extremely tender to the touch. The abdomen swells, particularly in its upper part, owing to gas having passed also into the cavity. Fever and vomiting develop and the person passes into a state of circulatory collapse or SHOCK. Such a condition may be fatal if not properly treated.

Treatment All food should be withheld and the patient given intravenous ?uids to resuscitate them and then to maintain their hydration and electrolyte balance. An operation is urgently necessary, the abdomen being opened in the middle line, the perforated portion of bowel found, the perforation stitched up, and appropriate antibiotics given.

Obstruction means a stoppage to the passage down the intestine of partially digested food. Obstruction may be acute, when it comes on suddenly with intense symptoms; or it may be chronic, when the obstructing cause gradually increases and the bowel becomes slowly more narrow until it closes altogether; or subacute, when obstruction comes and goes until it ends in an acute attack. In chronic cases the symptoms are milder in degree and more prolonged.

Causes Obstruction may be due to causes outside the bowel altogether, for example, the pressure of tumours in neighbouring organs, the twisting around the bowel of bands produced by former peritonitis, or even the twisting of a coil of intestine around itself so as to cause a kink in its wall. Chronic causes of the obstruction may exist in the wall of the bowel itself: for example, a tumour, or the contracting scar of an old ulcer. The condition of INTUSSUSCEPTION, where part of the bowel passes inside of the part beneath it, in the same way as one turns the ?nger of a glove outside in, causes obstruction and other symptoms. Bowel within a hernia may become obstructed when the hernia strangulates. Finally some body, such as a concretion, or the stone of some large fruit, or even a mass of hardened faeces, may become jammed within the bowel and stop up its passage.

Symptoms There are four chief symptoms: pain, vomiting, constipation and swelling of the abdomen.

Treatment As a rule the surgeon opens the abdomen, ?nds the obstruction and relieves it or if possible removes it altogether. It may be necessary to form a COLOSTOMY or ILEOSTOMY as a temporary or permanent measure in severe cases.

Tumours are rare in the small intestine and usually benign. They are relatively common in the large intestine and are usually cancerous. The most common site is the rectum. Cancer of the intestine is a disease of older people; it is the second most common cancer (after breast cancer) in women in the United Kingdom, and the third most common (after lung and prostate) in men. Around 25,000 cases of cancer of the large intestine occur in the UK annually, about 65 per cent of which are in the colon. A history of altered bowel habit, in the form of increasing constipation or diarrhoea, or an alternation of these, or of bleeding from the anus, in a middle-aged person is an indication for taking medical advice. If the condition is cancer, then the sooner it is investigated and treated, the better the result.... intestine, diseases of

Intracoronary Artery Stenting

A narrowed or blocked coronary artery (see ARTERIES) can compromise the blood supply to the heart muscle (see HEART, DISEASES OF). A supportive tube or stent passed into each affected artery can restore the blood supply. The stent has a HEPARIN coating to stop blood clots from forming. Since it was ?rst performed in 1987, intracoronary stents have cut the reblockage rate from one in three patients who have had coronary ANGIOPLASTY to fewer than one in ten in cases where a stent was used with angioplasty.... intracoronary artery stenting

Intrauterine Contraceptive Device (iucd)

A mechanical device, commonly a coil, inserted into the UTERUS to prevent CONCEPTION, probably by interfering with the implantation of the EMBRYO. For many women, IUCDs are an e?ective and acceptable form of contraception, although only about 10 per cent of women in the UK use them. The devices are of various shapes and made of plastic or copper; most have a string that passes through the cervix and rests in the vagina.

About one-third of women have adverse effects as the result of IUCD use: common ones are backache and heavy menstrual bleeding (see MENSTRUATION). The frequency of unwanted pregnancies is about 2 per 100 women-years of use. (See CONTRACEPTION.)... intrauterine contraceptive device (iucd)

Inula Racemosa

Cephaelis ipecacuanha


Importance: Ipecac is a small evergreen herb with much branched beaded roots. It is used in powdered form or as liquid total extract, syrup and tincture. Ipecac syrup in small doses is used as an expectorant, as it is well tolerated by children. It is used in treatment of whooping cough. Ipecac with opium as in Dover’s powder is used as a diaphoretic, tincture and syrup. Emetine hydrochloride in the form of injection is used for treatment of amoebic dysentery. Emetine bismuth iodide is also given orally for amoebic dysentery. Ipecac is also used as gastric stimulant and as an anti-inflammatory agent in rheumatism.

Distribution: The plant is a native of Bolivia and Brazil. It is cultivated in Mungpoo, near Darjeeling and on the Nilgiris, especially New Kallar, and at the Rungbee Cinchona plantation in Sikkim.

Botany: Cephaelis ipecacuanha (Brot.) A. Rich. syn. Psychotria ipecacuanha Stokes. belongs to the family Rubiaceae. The plant grows upto 0.7m high, with slender cylindrical stem. When mature the roots are dark brown and have transverse furrows giving it a beaded appearance. Above ground stem is quadrangular and trailing with few or new branches. Leaves are opposite near the top of the plant and alternate below, 5-10x3-6cm area, dark green above and pale green underneath. Flowers are white, sessile, funnel-like, less than 1cm wide and are borne in dense clusters. Fruit is purple with two stones containing single seed (Husain, 1993).

Agrotechnology: Ipecac prefers an average rainfall ranging between 2000-3000mm and evenly distributed. Maximum temperature should not exceed 38 C and the minimum not below 10 C. It thrives well in tropical mild humid climates similar to Malaysian rain forests. Virgin forest soils rich in humus are ideal for Ipecac. It prefers deep medium fertile soils which are acidic and rich in humus, potash and magnesium. Soil should be well drained and protected from wind and storm. As Ipecac grows only in shade, it can be cultivated as an intercrop, or planted in artificially shaded beds. The plant is propagated both by seeds and vegetatively by root, stem and leaf cuttings. Vegetative propagation is preferred to maintain genetic uniformity of the plant. Most of the commercial plantations are raised by seeds. Raised seed beds of 2x6m size are made and are mi xed with well rotten leaf compost and sand. These are provided with shade on the top as well as on the sides. Seeds are drilled or broadcasted in the beds and watered regularly. Seeds take 3-5 months to germinate. Seed treatment with limewater for 48 hours or H2O2 improves germination. It has been observed that providing mulch or black polythene in nursery beds improves germination as well as results in control of weeds. The suitable season of planting is January-March in West Bengal. Seedlings are planted in production beds at a spacing of 10x10cm after they are 8-12 weeks old. In West Bengal, it is a practice to transfer seedlings to other nursery beds before being transferred to final production seedbeds. FYM and leaf compost application is required during second and third year. Super phosphate applications is found to improve root growth. Frequent irrigation is required. Waterlogging should be avoided. Both the seedbeds and production beds should be kept free from weeds. Seedlings are often attacked by damping off fungi like Rhizoctonia sp. in nursery. It is better to treat the seeds with a suitable seed dressing fungicide before planting. Fusarium wilt caused by F. moniliforme has been reported from India. The plants are ready for harvesting after 4 years. The roots should be dug out, washed and dried in the sun. Rhizome and root are the economical parts (Husain, 1993).

Properties and activity: Ipecac root contains 2.2-2.5% total alkaloids. The main alkaloids are cephaeline and emetine. In addition, it also contains psychotrine and psychotrine ethyl ether. The drug also contains a crystalline glucosidal tannin, starch and calcium oxalate (60-70% of the alkaloids is emetine). Root contains minor amounts of O-methyl psychotrine, emetamine, protoemetine and others. Other constituents of ipecac include choline, glycoside-ipecoside, saponins, resins, tannins-ipecacuanhin, an allergen composed of mixture of glycoproteins, ipecacuanhic acid, a neutral monoterpene acid and calcium oxalate. Cephaeline could be converted into emetine on methylation.

The powdered dried rhizome and root cause severe asthmatic attacks and vasomotorrhinitis. Emetine hydrochloride is anti-amoebic. Root is emetic, expectorant and diaphoretic (Husain et al, 1992).... ipecac

Siddha/Tamil: Sakkareivelleikulan- gu.

Unani: Shakarkand, Rataalu.

Action: Root—used in strangury, urinary discharges, burning sensation, thirst. Whole plant—used in low fever and skin diseases.

Cooked tubers contain reducing sugars 6.45, sucrose 2.23, maltose 864, dextrins 0.51 and polysaccharides 14-13%. Cooking increases the sweetness as a result of the hydrolysis of starch to maltose and dextrins through the action of beta-amylase.

Sweet potatoes are rich in starch content. During the storage a part of starch content is converted into reducing sugars and subsequently into sucrose. In a sample stored for 5 months, the starch content was reduced from 19.1% to 14.1% while the percentage of reducing sugars (as dextrose) and sucrose increased from 0.9 to 1.7 and 1.9 to 6.1% respectively.

Indian types with white flesh contain little or no carotene, while American types with pink flesh contain as high as 5.4-7.2 mg/100 g of carotene. Vitamins present in the tubers are : thiamine 0.09-0.14, riboflavin 0.05-0.10 and vitamin C 16-22 mg/100 g.

The hot aqueous extract of leaves exhibits significant inhibitory activity of rat lens aldose reductase (AR). Ellagic and 3,5-dicaffoylquinic acids have been isolated as potent inhibitors.

The leaves also contain polysaccha- rides which increase the platelet count in experimental animals due to enhanced production ofthrombopoietin.

From the stem and root, hexadecyl, octadecyl and eicosyl p-coumarates have been isolated.

The tubers show significant lectin activity and exhibit haemagglutinating activity in trypsinized rabbit erythro- cytes.... ipomoea batatas

Irish Breakfast - A Well Known Type Of Black Tea

Black tea is popular since ancient times when it was used even for meditation. Irish Breakfast black tea has lots of benefits if you drink it moderately and follow the storage instructions. Short description of Irish Breakfast tea Irish breakfast tea is a mixture of strong Indian black teas grown in Assam region. As a black tea, it has a strong flavour and higher caffeine content than green teas but considerably less than coffee. This type of tea is obtained allowing the tea leaves to fully oxidize naturally before being dried. The leaves are left to dry in wooden boxes, then rolled and stretched damp and cold. This process gives black leaves. In Chinese tradition it is also named Hongcha. This type of black tea keeps its flavor better and longer than green tea. Infusion color goes from dark red to brown and may have many intense flavors like almonds, wild flowers, fruits or malt. Due to its strength, Irish breakfast tea is usually served with milk, but may also be consumed plain or with lemon or sugar. This type of tea is often drunk in the morning. When it comes to storage, it is advisable to keep Irish Breakfast tea in ceramic, porcelain containers or in metal airtight boxes in a clean dry air light place. Don’t keep the tea in the refrigerator as it will lose its flavor because of too much moisture. Ingredients of Irish Breakfast tea Like most teas, the Irish breakfast tea version contains flavanoids, which contain anti-oxidative properties when consumed. Recent studies have shown that this type of tea also contains more caffeine than other teas. How to prepare the Irish Breakfast tea If you are using tea bags, usually use 1 tea bag per cup of water. Pour boiling water, in order to cover the leaves. Allow the Irish Breakfast tea to infuse for 3-5 minutes allowing the steam to release the leaves’ flavor. After that, remove the leaves, blend, let it cool for a few moments and enjoy. Your specific tea may come with a recommendation for preparation and brewing as well. Benefits of Irish Breakfast tea Like other black teas, consumption of Irish Breakfast tea has many health benefits. Drinking Irish Breakfast tea strengthens teeth and bones and helps boost the immune system keeping the viruses away. It also prevents tooth decay. It blocks LDL (bad) cholesterol and increase HDL (good) cholesterol, which improves artery function. The essential oils in tea leaves help digestion. Caffeine contained in this type of tea has many positive functions like relieving headaches, improving mood and helping concentration. It is also considered an old remedy for asthma symptoms. It also eliminates tiredness. Irish Breakfast tea reduces tumor growth. Some studies showed that TF-2 substance contained in tea, cause destruction of colon and rectum cancer cells, contributing to tumor reduction. Researchers also found that the benefits of black tea may include lowering the risk of heart attack and stroke. According to their findings, certain compounds found in the tea help relax and expand the arteries, thus increasing blood flow to the heart and minimizing clogging of the arteries. It is said that 4 cups of Irish Breakfast tea daily lower with 50% the risk of heart attack. Side effects of Irish Breakfast tea The side effect of Irish Breakfast tea may arise if you drink too much. They are mostly associated with caffeine may cause restlessness, palpitations, difficulty sleeping, anxiety, irritability, increased heart rate, and elevated blood pressure. Caffeine is also diuretic. Due to its interesting flavors and benefits, Irish Breakfast teas are suitable for regular consumption, but always remember to keep your moderation when you drink it.... irish breakfast - a well known type of black tea

The IMMUNISATION of a person by an ANTIGEN they do not have but which is present in other people. For example, a rhesus-negative mother does not carry the rhesus antigen. If she carries a rhesus-positive baby, passage of the rhesus antigen from the baby into the mother’s circulation may cause her to be iso-immunised. Her immune system (see IMMUNITY) may then produce ANTIBODIES to the rhesus antigen. When she next becomes pregnant, if the baby is again rhesus positive, the mother will produce large amounts of anti-Rh antibodies which can enter the fetal circulation and cause its blood cells to break up. (See HAEMOLYTIC DISEASE OF THE NEWBORN; BLOOD GROUPS.)... iso-immunisation

Ischaemic Stroke

A STROKE that occurs when the ?ow of blood to a part of the brain is interrupted by a partial or complete THROMBOSIS of the supplying artery or ARTERIES, or by a clot of blood that has detached itself from elsewhere in the circulatory system – for instance, a deep vein thrombosis (DVT) – and blocked a cerebral artery. Stroke is the second most common cause of death worldwide. Its treatment is di?cult and prevention is best targeted at those who are at the highest absolute risk of stroke, because such people are likely to derive the greatest bene?t. They generally have a history of occlusive vascular diseases such as previous ischaemic stroke or a transient ischaemic attack (TIA), coronary heart disease (see HEART, DISEASES OF) or PERIPHERAL VASCULAR DISEASE. In the UK strokes affect about 200 people per 100,000 population annually, with the incidence rising sharply after the age of 55. At the age of 70 the incidence is around 15 people per 1,000 of population; at 80 the ?gure is double that.

About 80 per cent of patients survive an acute stroke and they are at risk of a further episode within a few weeks and months; about 10 per cent in the ?rst year and 5 per cent a year after that. HYPERTENSION, smoking, HYPERLIPIDAEMIA and raised concentration of blood sugar, along with OBESITY, are signi?cant pointers to further strokes and preventive steps to reduce these factors are worthwhile, although the reduction in risk is hard to assess. Even so, the affected person should stop smoking, greatly reduce alcohol intake, check for and have treated diabetes, reduce weight and exercise regularly. In any case, a diet rich in fresh fruit and vegetables and low in fat and salt, exercise and the avoidance of smoking may reduce the risk of having a ?rst stroke.

The evidence is inconclusive that patients with ischaemic stroke should be treated with antihypertensives. Furthermore, neither the starting blood pressure nor the best drug regimen or its starting time are generally agreed. Studies on the most e?ective methods of preventing and treating stroke are continuing; meanwhile available evidence suggests that an active approach to prevention of primary and secondary hypertension will bene?t patients and usually be cost-e?ective.... ischaemic stroke

Juvenile Idiopathic Arthritis (jia)

Previously called juvenile rheumatoid arthritis and juvenile chronic arthritis, this is a set of related conditions of unknown cause affecting children. Characteristically, the synovial membrane of a joint or joints becomes in?amed and swollen for at leat six weeks (and often very much longer – even years). About 1 in 10,000 children develop it each year, many of whom have certain HLA genetic markers, thought to be important in determining who gets the illness. In?ammatory CYTOKINES play a big part.

Clinical features There are various types. The oligoarthritic type involves 1–4 joints (usually knee or ankle) which become hot, swollen and painful. One complication is an in?ammation of the eyes – UVEITIS. The condition often ‘burns out’, but may reappear at any time, even years later.

The polyarthritic type is more like RHEUMATOID ARTHRITIS in adults, and the child may have persistent symptoms leading to major joint deformity and crippling.

The systemic type, previously called Still’s disease, presents with a high fever and rash, enlarged liver, spleen and lymph nodes, and arthritis – although the latter may be mild. In some children the illness becomes recurrent; in others it dies down only to return as polyarthritis.

Complications These include uveitis, which can lead to loss of vision; a failure to thrive; osteoporosis (see under BONE, DISORDERS OF); joint deformity; and psychosocial diffculties.

Treatment This includes ANTIPYRETICS and ANALGESICS, including NON-STEROIDAL ANTIINFLAMMATORY DRUGS (NSAIDS), intra-articular steroid injections, anti-tumour necrosis factor drugs and steroids.

Physiotherapy is vital, and children may need to wear splints or other orthotic devices to alleviate deformity and pain. Orthopaedic operative procedures may be necessary.... juvenile idiopathic arthritis (jia)

Action: Antiasthmatic, antispasmodic, broncho-dilator, expectorant, mild sedative and relaxant. Used as a tabacco deterrent (as a major ingredient in many antismoking mixtures).

Key application: In the treatment of asthma, bronchitis. (German Commission E.) As respiratory stimulant. (The British Herbal Pharmacopoeia.)

Lobelia contains piperidine alkaloids, mainly lobeline, with lobelanine, lobelanidine, norlobelanine, isolobi- nine. Lobeline stimulates respiration in animals by stimulating respiratory centre and at high doses stimulates the vomiting centre.

Lobeline has similar but less potent pharmacological properties to nicotine but 1/20-1/5 as potent.

Lobeline (0.5%) has also been used as an active ingredient in skin-lightening preparations.

Clinical research could not demonstrate lobeline efficacy greater than placebo in smoking cessation. It was disallowed as an ingredient in antismoking products in the US in 1993. (Natural Medicines Comprehensive Database, 2007.)

The leaves contain beta-amyrin pal- mitate which possesses sedative and antidepressant properties comparable to the antidepressant drug mianserin. Methanolic extract of leaves exhibited antidepressant activity.

The leaf powder is toxic at 0.6-1.0 , (Francis Brinker.)... lobelia inflata

Mao Inhibition

The suppression of monoamine oxydase (flavin-containing amine oxydase). MAO is critical in modifying nerve-ending storage of certain mono­amines (in this case, epinephrine, norepinephrine and dopamine...another type of MAO works on histamines), and MAO inhibitor drugs were, along with tricyclics, the first wave of anti-depressants. The problem was that if you ate brie cheese or chopped chicken livers while taking the drugs you could get a nosebleed or cerebral aneurysm...a double adrenergic whammy, since some foods are also strongly MAO-inhibiting (at least functionally). Although most current manuals (Merck’s and Harrison’s among others) consider these first generation drugs as safer and preferable to the recent Prozac and such, fashion am fashion, with docs as much as patients. Most of the patients a doctor sees are People That See Doctors (most Americans have infrequent medical contact). Some come with clippings in hand, a few find out about new stuff before their doctor does (they only have ONE patient..themselves) and the pressure for gilt-edged newness is hard to resist all around. The only herb I know of with any consequential MAO inhibition is Hypericum, and its effect, although not to be ignored, is less than French semi-soft cheeses.... mao inhibition

Minimally Invasive Surgery (mis)

More popularly called ‘keyhole surgery’, MIS is surgical intervention, whether diagnostic or curative, that causes patients the least possible physical trauma. It has revolutionised surgery, growing from a technique used by gynaecologists, urologists and innovative general surgeons to one regularly used in general surgery, GYNAECOLOGY, UROLOGY, thoracic surgery, orthopaedic surgery (see ORTHOPAEDICS) and OTORHINOLARYNGOLOGY.

MIS is commonly carried out by means of an operating laparoscope (a type of ENDOSCOPE) that is slipped through a small incision in the skin. MIS now accounts for around 50 per cent

of all operations carried out in the UK. A small attachment on the end of the laparoscope provides an image that can be magni?ed on a screen, leaving the surgeon’s hands free to operate while his assistant operates the laparoscope. Halogen bulbs, ?breoptic cables and rod lenses have all contributed to the technical advancement of laparoscopes. Operations done in this manner include extracorporeal shock-wave LITHOTRIPSY for stones in the gall-bladder, biliary ducts and urinary system; removal of the gall-bladder; appendicectomy; removal of the spleen and adrenal glands; and thoracic sympathectomy. MIS is also used to remove cartilage or loose pieces of bone in the knee-joint.

This method of surgery usually means that patients can be treated on a day or overnight basis, allowing them to resume normal activities more quickly than with conventional surgery. It is safer and lessens the trauma and shock for patients needing surgery. MIS is also more cost e?ective, allowing hospitals to treat more patients in a year. Surgeons undertake special training in the use of MIS, a highly skilled technique, before they are permitted to use the procedures on patients. The use of MIS for hernia repair, colon surgery and repairs of duodenal perforations is under evaluation and its advantages will be enhanced by the development of robotic surgical techniques.... minimally invasive surgery (mis)

Monoamine Oxidase Inhibitors (maois)

These are drugs that destroy, or prevent the action of, monoamine oxidase (MAO). Monoamines, which include NORADRENALINE and tyramine, play an important part in the metabolism of the BRAIN, and there is some evidence that excitement is due to an accumulation of monoamines in the brain. MAO is a naturally occurring ENZYME which is concerned in the breakdown of monoamines. MAOIs were among the earliest ANTIDEPRESSANT DRUGS used, but they are now used much less than tricyclic and related antidepressants, or SELECTIVE SEROTONIN-REUPTAKE INHIBITORS (SSRIS) and related antidepressants, because of the dangers of dietary or drug interactions – and because MAOIs are less e?ective than these two groups.

An excessive accumulation of monoamines can induce a dangerous reaction characterised by high blood pressure, palpitations, sweating and a feeling of su?ocation. Hence the care with which MAOI drugs are administered. What is equally important, however, is that in no circumstances should a patient receiving any MAOI drug eat cheese, yeast preparations such as Marmite, tinned ?sh, or high game. The reason for this ban is that all these foodstu?s contain large amounts of tyramine which increases the amount of certain monoamines such as noradrenaline in the body. (See MENTAL ILLNESS.)

There are also certain drugs, such as AMPHETAMINES and PETHIDINE HYDROCHLORIDE, which must not be taken by a patient who is receiving an MAOI drug. The MAOIs of choice are phenelzine or isocarboxazid because their stimulant effects are less than those of other MAOIs, making them safer.... monoamine oxidase inhibitors (maois)

National Institute For Clinical Excellence (nice)

This special health authority in the National Health Service, launched in 1999, prepares formal advice for all managers and health professionals working in the service in England and Wales on the clinical- and cost-e?ectiveness of new and existing technologies. This includes diagnostic tests, medicines and surgical procedures. The institute also gives advice on best practice in the use of existing treatments.

NICE – its Scottish equivalent is the Scottish Health Technology Assessment Centre – has three main functions:

appraisal of new and existing technologies.

development of clinical guidelines.

promotion of clinical audit and con?dential inquiries. Central to its task is public concern about ‘postcode prescribing’ – that is, di?erent availability of health care according to geography.

In 2003 the World Health Organisation appraised NICE. Amongst its recomendations were that there should be greater consistency in the methods used for appraisal and the way in which results and decisions were reported. WHO was concerned about the need for transparency about the con?ict between NICE’s use of manufacturers’ commercial evidence in con?dence, and believed there should be greater de?nition of justi?cation for ‘threshold’ levels for cost-e?ectiveness in the Centre’s judgement of what represents value for money.

In all, WHO was congratulatory – but questions remain about the practical value and imlementation of NICE guidelines.... national institute for clinical excellence (nice)

Neonatal Intensive Care

The provision of a dedicated unit with special facilities, including one-to-one nursing and appropriate technology, for caring for premature and seriously ill newborn babies. Paediatricians and neonatologists are involved in the running of such units. Not every maternity unit can provide intensive care: for example, the provision of arti?cial ventilation, other than as a holding procedure until a baby can be transferred to a better-equipped and better-serviced unit. Such hospitals tend to have special-care baby units, which are capable of looking after the needs of most, but not all, premature or ill babies.... neonatal intensive care

Nervous Impulse

This is transmitted chemically, by the formation at nerve-endings of chemical substances. When, for example, a NERVE to a muscle is stimulated, there appears at the NEUROMUSCULAR JUNCTION the chemical substance, ACETYLCHOLINE. Acetylcholine also appears at endings of the parasympathetic nerves (see NERVOUS SYSTEM) and transmits the e?ect of the parasympathetic impulse. When an impulse passes down a sympathetic nerve, the e?ect of it is transmitted at the nerve-ending by the chemical liberated there: ADRENALINE or an adrenaline-like substance.... nervous impulse

Neem Tea - An Indian Herbal Tea

Neem tea is a refreshing herbal tea, with origins in South Asia. Despite its bitter taste, it is often recommended as a beverage thanks to its many health benefits. Read this article to find out more about neem tea! About Neem Tea Neem tea is made from the leaves of the Neem tree. The tree can be found in India, Bangladesh and Pakistan. It is an evergreen tree which can grow up to twenty feet in just three years, and it starts bearing fruit after 3-5 years. However, during periods of severe drought, it may shed most or even all of its leaves. The green leaves are 20-40cm long, with medium to dark green leaflets about 3-8cm long; the terminal leaflet is usually missing. The tree’s flowers are small, white and fragrant, arranged axillary. The fruit has an olive-like form, with a thin skin and a yellow-white, fibrous and bittersweet pulp. How to prepare Neem Tea To brew a cup of neem tea, you have to follow a few simple steps. First, boil the necessary amount of water. Then, pour it over a cup with includes a few neem leaves. Let it steep for about 5 minutes. Lastly, remove the leaves and, if you think it is needed, flavor it with honey and/or lemon. You can make your own stack of neem leaves for neem tea. If you’ve got neem trees around, gather leaves and leave them to dry. You can use fresh neem leaves, as well. In both cases though, you have to wash the leaves well before you use them. Once you’ve got the leaves ready, whether dry or fresh, just follow the earlier-mentioned steps. You can also make a cup of neem tea by using powdered neem leaf. Neem Tea Benefits Neem leaves have many antibacterial and antiviral properties. Thanks to this, neem tea is full of health benefits. Indians chew on neem twigs to have a good oral hygiene. However, a cup of neem tea can also help you maintain a good oral hygiene. It is useful in treating bad breath and gum disease, and it fights against cavities. Neem tea is also useful in treating fungal infections, such as yeast infections, jock itch, thrush, and ringworm. Neem tea can help you treat both indigestion and constipation. It is also useful when it comes to reducing swelling of the stomach and intestinal tract, and it can be used to counter ulcers and gout. Neem tea, when combined with neem cream, has anti-viral uses. It can help speed up the healing time and pain associated with herpes simplex 1, herpes zoster and warts. Neem tea is also used in the treatment of malaria and other similar diseases. It helps purify and cleanse the blood, as well; therefore, it increases liver function. Other important benefits that are related to consumption of neem tea are: treating pneumonia, treating diabetes, treating hypertension and heart diseases. Also, neem tea doesn’t have to be used only as a beverage. Because of its anti-parasitic use, you can bathe in it. This way, the tea acts as an antiseptic, killing the parasites. Neem Tea Side Effects While we can say that neem tea has plenty of important health benefits, don’t forget that there are a few side effects, as well. First of all, neem oil can be incredibly toxic for infants. Even a small amount of neem oil can cause death. Check to see if the neem tea you drink has neem oil among its ingredients. Or, just to be on the safe side, don’t give infants neem tea to drink. You shouldn’t drink neem tea if you have a history of stomach, liver or kidney problems. Some of its active ingredients can cause you harm in this case. Although rare, neem tea can also lead to allergic reactions. Symptoms in this case include difficulty in breathing, rashes, itching, or swelling of the throat or mouth. If you get any of these, stop drinking neem teaand contact your doctor. Drinking neem tea is a big no if you’re trying to conceive, or you’re already pregnant. In the first case, neem tea can work as a contraceptive, therefore lessening the chances of you getting pregnant. In the second case, consumption of neem tea can lead to miscarriages. Also, don’t drink more than six cups of neem teaa day - or any other type of tea. It won’t do you well, despite its many health benefits. Some of the symptoms you might get are: headaches, dizziness, insomnia, irregular heartbeats, vomiting, diarrhea and loss of appetite. If you get any of these symptoms, reduce the amount of neem tea you drink. As a herbal tea, neem tea is definitely good for your health. Still, despite its many health benefits, there are a few side effects as well. Keep them both in mind when drinking neem tea.... neem tea - an indian herbal tea

Non-accidental Injury (nai)

(See also CHILD ABUSE). Though NAI has traditionally been seen as abuse against children – and they are still the main victims – such injuries can also be in?icted on vulnerable adults. Adults with learning diffculties, dementias or physical disabilities su?ciently serious as to require institutional care (or who make heavy demands on relatives) are sometimes the victims of NAI. Health professionals, social workers and relatives should bear this possibility in mind when discovering unusual, severe or repeated bruising or fractures in vulnerable adults, even in circumstances where NAI may seem unlikely. (See also MUNCHAUSEN’S SYNDROME; PAEDOPHILIA.)... non-accidental injury (nai)

Nerves, Injuries To

These have several causes. Continued or repeated severe pressure may damage a nerve seriously, as in the case of a crutch pressing into the armpit and causing drop-wrist. Bruising due to a blow which drives a super?cially placed nerve against a bone may damage, say, the radial nerve behind the upper arm. A wound may sever nerves, along with other structures; this accident is specially liable to occur to the ulnar nerve in front of the wrist when a person accidentally puts a hand and arm through a pane of glass.

Symptoms When a sensory nerve is injured or diseased, sensation is immediately more or less impaired in the part supplied by the nerve. Ulceration or death of the tissue supplied by the defective nerve may occur. When the nerve in question is a motor one, the muscles governed through it are instantly paralysed. In the latter case, the portion of nerve beyond the injury degenerates and the muscles gradually waste, losing their power of contraction in response to electrical applications. Finally, deformities result and the joints become ?xed. This is particularly noticeable when the ulnar nerve is injured, the hand and ?ngers taking up a claw-like position. The skin may also be affected.

Treatment Damaged or severed (peripheral) nerve ?bres should be sewn together, using microsurgery. Careful realignment of the nerve endings gives the ?bres an excellent chance of regenerating along the right channels. Full recovery is rare but, with regular physiotherapy to keep paralysed muscles in good shape and to prevent their shortening, the patient can expect to obtain a reasonable return of function after a few weeks, with improvement continuing over several months.... nerves, injuries to

Non-steroidal Anti-inflammatory Drugs (nsaids)

These act by inhibiting the formation of PROSTAGLANDINS which are mediators of INFLAMMATION. They act both as ANALGESICS to relieve pain, and as inhibitors of in?ammation. Aspirin is a classic example of such a compound. Newer compounds have been synthesised with the aim of producing fewer and less severe side-effects. They are sometimes preferred to aspirin for the treatment of conditions such as RHEUMATOID ARTHRITIS, OSTEOARTHRITIS, sprains, strains and sports injuries. Their main side-effects are gastrointestinal: gastric ulcers and gastric haemorrhage may result (see STOMACH, DISEASES OF). This is because prostaglandins are necessary for the production of the mucous protective coat in the stomach and, when the production of prostaglandin is inhibited, the protection of the stomach is compromised. NSAIDs should therefore be used with caution in patients with DYSPEPSIA and gastric ulceration. The various nonsteroidal anti-in?ammatory drugs di?er little from each other in e?cacy, although there is considerable variation in patient response. Ibuprofen is one of the ?rst choices in this group of drugs as it combines good e?cacy with a low incidence of side-effects and administration is only required twice daily. Other drugs in this series include diclofenac, fenbufen, fenclofenac, fenoprofen, feprazone, ?urbiprofen, indomethacin, indoprofen, ketoprofen, ketorolac, naproxen, piroxicam, sulindac, tiaprofenic acid and tolmetin.... non-steroidal anti-inflammatory drugs (nsaids)

Passiflora Incarnata


Family: Passifloraceae.

Habitat: Native of South-east America; grown in Indian gardens.

English: Wild Passion Flower, Maypop.

Action: Flowering and fruiting dried herb—mild sedative, hypnotic, tranquilizer, hypotensive, vasodilator, antispasmodic, anodyne, anti-inflammatory,

Key application: In nervous restlessness, irritability and difficulty in falling asleep. (German Commission E, ESCOP, The British Herbal Compendium, The British Herbal Pharmacopoeia, WHO.) The British Herbal Compendium also indicated it in neuralgia, dysmenorrhoea, and nervous tachycardia.

The herb contains flavonoids (up to 2.5%), in particular C-glycosylflavones; cyanogenic glycoside, gynocardine.

The alkaloid harman has been isolated, but the presence of harmine, har- maline, harmol and harmalol has been disputed. The alkaloid and flavonoids are reported to have sedative activity in animals. Apigenin exhibits antispasmodic and anti-inflammatory activity.

Passion Flower was formerly approved as an OTC sedative in the USA, but it was taken off the market in 1978 because safety and effectiveness had not been proven. An animal study in 1977 suggested that apigenin binds to central benzodi-zepine receptors (possibly causing anxiolytic effects). (Natural Medicines Comprehensive Database, 2007.)

The drug is used in homoeopathic medicine for epilepsy.

The herb exhibits a motility-inhi- biting effect in animal experiments.

Passion Flower, used as an adjunct to clonidine, was superior to clonidine for mental symptoms of opiate withdrawal. (Sharon M. Herr.)... passiflora incarnata

Pelvic Inflammatory Disease(pid)

An infection of the endometrium (membraneous lining) of the UTERUS, FALLOPIAN TUBES and adjacent structures caused by the ascent of micro-organisms from the vulva and vagina. Around 100,000 women develop PID each year in the UK; most of those affected are under 25 years of age. Infection is commonly associated with sexual intercourse; Chlamydia trachomatis (see CHLAMYDIA) and Neisseria gonorrhoeae (see NEISSERIACEAE) are the most common pathogens. Although these bacteria initiate PID, opportunistic bacteria such as STREPTOCOCCUS and bacteroides often replace them.

The infection may be silent – with no obvious symptoms – or symptoms may be troublesome, for example, vaginal discharge and sometimes a palpable mass in the lower abdomen. If a LAPAROSCOPY is done – usually by endoscopic examination – overt evidence of PID is found in around 65 per cent of suspected cases.

PID may be confused with APPENDICITIS, ECTOPIC PREGNANCY – and PID is a common cause of such pregnancies – ovarian cyst (see OVARIES, DISEASES OF) and in?ammatory disorders of the intestines. Treatment is with a combination of ANTIBIOTICS that are active against the likely pathogens, accompanied by ANALGESICS. Patients may become seriously ill and require hospital care, where surgery is sometimes required if conservative management is unsuccessful. All women who have PID should be screened for sexually transmitted disease and, if this is present, should be referred with their partner(s) to a genito-urinary medicine clinic. Up to 20 per cent of women who have PID become infertile, and there is a seven-to ten-fold greater risk of an ectopic pregnancy occurring.... pelvic inflammatory disease(pid)

Pleurisy Root Tea - Tea Of The Indigenous Indians

Pleurisy root tea is an aromatic herbal tea which you are bound to enjoy. The indigenous Indians used to drink it a lot, especially thanks to its health benefits. About Pleurisy Root Tea Pleurisy root tea is made from the roots of the pleurisy plant, also known as the butterfly weed. The plant grows in North America. It can grow up to 1m tall, with multiple stems and spirally-arranged, spear-pointed leaves that are 5-12cm long. Clusters of orange or yellow flowers bloom during summertime, attracting butterflies, insects and birds. The plant can be found growing on dry, open fields, under direct sunlight. How to prepare Pleurisy Root Tea If you want to enjoy a cup of pleurisy root tea, add a teaspoon of dried, chopped roots to a cup of freshly boiled water. Let it steep for 10-15 minutes before straining it to remove the herbs. Sweeten it with honey or fruit juice, if necessary. Pleurisy Root Tea Benefits Pleurisy root contains various active constituents, such as glycosides, resins, amino acids, volatile oil, glucosidal principal, lupeol, and alkaloids. They are transferred to the pleurisy root tea, as well. Because if this, the tea has lots of important health benefits. Pleurisy root tea is often included in treatments for various respiratory ailments and pulmonary infections, for example pleurisy, asthma, bronchitis or pneumonia. It helps alleviate pain and congestion by reducing the mucus thickness in the lungs and enabling the patient to expel the blockage. Drinking pleurisy root tea helps both with fevers and detoxification, as it stimulates sweating and perspiration. It is also useful as an herbal treatment for colds and influenza. You can also drink pleurisy root tea if you’ve got problems with diarrhea, dysentery, chronic rheumatism, colic, muscle tension and spasm. Pleurisy root tea can also be used topically. You can soak a clean cloth with the tea and use it to treat swellings, bruises, lameness, wounds and skin ulcers. Pleurisy Root Tea Side Effects If you’re pregnant, you shouldn’t drink pleurisy root tea. It may cause uterine contractions, which could lead to miscarriages. Also, it is safer not to drink this tea if you’re breast feeding. Children shouldn’t drink pleurisy root tea either, because of the small amount of cardiac glycosides. You should be careful with the amount of pleurisy root tea you drink if you’ve got cardiovascular problems or you’re taking cardiac glycosides. Also, if you’re taking any other medication, check with your doctor if it’s safe to drink pleurisy root tea. Don’t drink more than 3-4 cups of pleurisy root tea a day. If you drink too much, it might lead to symptoms such as intestinal cramping, nausea, vomiting, and diarrhea. Pleurisy root tea is ideal for an everyday beverage. It has many health benefits and only a few side effects. Once you try it, you’ll surely enjoy it!... pleurisy root tea - tea of the indigenous indians

Quality Improvement / Continuous Quality Improvement

The sum of all the activities which create desired change in quality. In the health care setting, quality improvement requires a feedback loop which involves the identification of patterns of the care of individuals (or of the performance of other systems involved in care), the analysis of those patterns in order to identify opportunities for improvement (or instances of departure from standards of care), and then action to improve the quality of care for future patients. An effective quality improvement system results in step-by-step increases in quality of care.... quality improvement / continuous quality improvement

Shaken Impact Syndrome

A type of non-accidental head-injury to infants. A study published in 2000 (Lancet, 4 November) suggests that almost 25 out of 100,000 children under a year old sustain brain damage from shaken impact syndrome, even if they do not strike any hard surface. So, of around 685,000 babies in this age-group in Britain, as many as 170 a year may suffer injury from violent shaking. The median age for admission to hospital for the condition in Scotland was 2.2 months in the 18 months from July 1998. A Swedish report has concluded that children at risk from CHILD ABUSE can be identi?ed and the incidence reduced by legislation banning corporal punishment.
