| antibody-coated bacteria test, urinary | Fluorescent antibody technique for visualizing antibody-bacteria complexes in urine. The presence or absence of antibody-coated bacteria in urine correlates with localization of urinary tract infection in the kidney or bladder, respectively. (12 Dec 1998) |
| coated pit | <biology> First stage in the formation of a coated vesicle. (18 Nov 1997) |
| coated pits, cell-membrane | Specialised regions of the cell membrane composed of pits coated with a bristle covering made of the protein clathrin. These pits are the entry route for macromolecules bound by cell surface receptors. The pits are then internalised into the cytoplasm to form the coated vesicles. (12 Dec 1998) |
| coated tongue | A tongue with a whitish layer on its upper surface, composed of epithelial debris, food particles, and bacteria; often an indication of indigestion or of fever. Synonym: furred tongue. (05 Mar 2000) |
| coated vesicle | <cell biology> Vesicle formed as an invagination of the plasma membrane (a coated pit) and that is surrounded by a basket of clathrin. Associated with receptor mediated pinocytosis and receptor recycling. (18 Nov 1997) |
| coated vesicles | Vesicles formed when cell-membrane coated pits (coated pits, cell-membrane) invaginate and pinch off. The outer surface of these vesicles is covered with a lattice-like network of the protein clathrin. Shortly after formation, however, the clathrin coat is removed and the vesicles are referred to as endosomes. (12 Dec 1998) |
| tablets, enteric-coated | Tablets coated with material that delays release of the medication until after they leave the stomach. (12 Dec 1998) |
| enteric-coated | A term designating a special coating applied to tablets or capsules which prevents release and absorption of their contents until they reach the intestines. (18 Nov 1997) |
| enteric coated tablet | An oral dosage form in which a tablet is coated with a material to prevent or minimise dissolution in the stomach but allow dissolution in the small intestine. This type of formulation either protects the stomach from a potentially irritating drug (e.g., aspirin) or protects the drug (e.g., erythromycin) from partial degradation in the acidic environment of the stomach.

| alpha-lactyl-thiamin pyrophosphate | An intermediate formed in the oxidative decarboxylation of pyruvate. Compare: pyruvate dehydrogenase (lipoamide). Synonym: alpha-lactyl-thiamin pyrophosphate. (05 Mar 2000) |
| thiamin | A member of the water-soluble B vitamin group, necessary for energy production and carbohydrate metabolism. Deficiency is known as beriberi. (27 Sep 1997) |
| thiamin deficiency | An endemic form of polyneuritis (nerve inflammation), due to an unbalanced diet, with a deficiency of vitamin B1(thiamin). Common in those who chronically abuse alcohol. Synonym: beriberi. (27 Sep 1997) |
| thiamin hydrochloride | A coenzyme used in the prevention of beriberi and other conditions associated with a deficiency of thiamin in the diet. Synonym: aneurine hydrochloride. (05 Mar 2000) |
| thiamin hydrochloride unit | The antineuritic activity of 0.003 mg of the standard crystalline vitamin B1 hydrochloride. Synonym: vitamin B1 hydrochloride unit. (05 Mar 2000) |
