Taste Bud: From 1 Different Sources

One of 10,000 specialized structures located mainly on the tongue, with some at the back of the throat and on the palate.

Each bud contains about 25 sensory receptor cells, with tiny taste hairs that respond to food and drink.

Taste buds on different parts of the tongue sense the 4 basic tastes: bitter, sour, salty, and sweet.

buds from stomatitis, mouth cancer, or radiotherapy to the mouth; or damage to nerves that carry taste sensations.

Buerger’s disease A rare disorder, also called thromboangiitis obliterans, in which the arteries, nerves, and veins in the legs, and sometimes those in the arms, become severely inflamed. Blood supply to the toes and fingers becomes cut off, eventually causing gangrene. The disease is most common in men under the age of 45 who smoke heavily. bulimia An illness that is characterized by bouts of overeating usually followed by self-induced vomiting or excessive laxative use. Most sufferers are girls or women between the ages of 15 and 30. In some cases, the symptoms coexist with those of anorexia nervosa. Repeated vomiting can lead to dehydration and loss of potassium, causing weakness and cramps, and tooth damage due to the gastric acid in vomit. Treatment includes supervision and regulation of eating habits, and sometimes, antidepressant drugs and/or psychotherapy. bulk-forming agent A substance that makes stools less liquid by absorbing water: a type of antidiarrhoeal drug. bulla A large air- or fluid-filled bubble, usually in the lungs or skin. Lung bullae in young adults are usually congenital. In later life, lung bullae develop in patients with emphysema. Skin bullae are large, fluid-filled blisters with a variety of causes, including the bullous disease pemphigus.... budesonide

Budgerigar-fancier’s Lung

Budgerigar-fancier’s lung is a form of extrinsic allergic ALVEOLITIS, resulting from sensitisation to budgerigars, or parakeets as they are known in North America. Skin tests have revealed sensitisation to the birds’ droppings and/or serum. As it is estimated that budgerigars are kept in 5– 6 million homes in Britain, current ?gures suggest that anything up to 900 per 100,000 of the population are exposed to the risk of developing this condition.... budgerigar-fancier’s lung

Programme Budgeting

The process of making resources available to attain the objectives of programmes. Programme budgeting differs from ordinary budgeting in that the emphasis is on the results to be achieved rather than on unconnected budgetary items.

Zanthoxylum Budrunga

Wall. ex DC.

Synonym: Z. limonella (Dennst.) Alston. Z. rhetsa DC. Fagara budrunga Roxb. F. rhetsa Roxb.

Family: Rutaceae.

Habitat: Meghalaya, foothills of Assam and Peninsular India.

Ayurvedic: Tumburu (Kerala), Ashvaghra, Tejabala.

Siddha/Tamil: Tratechai.

Action: Fruits—used for diarrhoea, dyspepsia; asthma, bronchitis; rheumatism; diseases of the mouth and teeth. Pericarp—astringent, digestive, stimulant. Essential oil—disinfectant, used in infective dermatosis. Bark—cholinergic, diuretic, hypoglycaemic, spasmolytic. Root—emmenagogue, febrifuge.

The trunk-bark from Assam gave alkaloids—chelerythrine (0.014%), evodiamine (0.03%) and hydoxyevodi- amine (0.05%). The essential oil from the fruit contains l-sabinene, alpha- terpinene, beta-phellandrene, 1,4-cine- ole, decanal, octanal, terpinen-4-ol, dihydrocarveol, l-cryptone and cumi- naldehyde.

The essential oil exhibits anti-inflammatory, anaesthetic and antago- nisic activity.

Z. nitidum (Roxb.) DC. (Bihar eastwards to Sikkim and Assam) is known as Tezmul in Assam. The root is used in toothache and stomachache.

The plant is used as one of the ingredients in the preparation of pharmaceutical tablets given to drug addicts for the treatment of withdrawl symptoms.

Methanolic extract of the roots gave nitidine, chelerythrine and isogari- dine. The extract showed antitumour property.

Z. ovalifolium Wight (Eastern Himalayas, Meghalaya, the Western Ghats of South Kanara and Kerala) is known as Armadalu in Karnataka and Diang-shih in Meghalaya (Khasi Hills). The leaf contains diosmetin and the heartwood contains flavonoids of dihydrofisetin and cinnamaldehyde. The bark and fruit possess properties similar to other species of the genus.... zanthoxylum budrunga

Budd–chiari Syndrome

A rare disorder in which the veins draining blood from the liver become blocked or narrowed.

Blood accumulates in the liver, which swells.

Liver failure and portal hypertension result.

Treatment is aimed at removing the cause of the obstruction: this may be a blood clot, pressure on the veins from a liver tumour, or a congenital abnormality of the veins.

In most cases, treatment has only a limited effect and, unless a liver transplant can be done, the disease is fatal within 2 years.... budd–chiari syndrome

Taste, Loss Of

Loss of the sense of taste, usually as a result of the loss of the sense of smell.

The most common cause is inflammation of the nasal passages.

Other causes of loss of taste include any condition that causes a dry mouth (see mouth, dry); natural degeneration of the taste buds; damage to the taste eign particles.

Tear production increases in response to eye irritation and emotion.... taste, loss of

Budd–chiari Syndrome

a rare condition that follows occlusion of the hepatic veins by thrombosis or nonthrombotic processes. In the majority of cases the cause is unknown but hypercoagulable states, local or disseminated malignancy, and infection are possible causes. It is characterized by abdominal pain, abdominal distension due to ascites, and jaundice. Clinical examination may reveal hepatomegaly, and *hepatic encephalopathy. [G. Budd (1808–82), British physician; H. Chiari (1851–1916), German pathologist]... budd–chiari syndrome

Taste Buds

the sensory receptors concerned with the sense of taste (see illustration). They are located in the epithelium that covers the surface of the *tongue, lying in the grooves around the papillae, particularly the circumvallate papillae. Taste buds are also present in the soft palate, the epiglottis, and parts of the pharynx. When a taste cell is stimulated by the presence of a dissolved substance impulses are sent via nerve fibres to the brain. From the anterior two-thirds of the tongue impulses pass via the facial nerve. The taste buds in the posterior third of the tongue send impulses via the glossopharyngeal nerve.... taste buds
