| BAT | basic aid training; best available technology; blunt abdominal trauma; brown adipose tissue |
| BCL | basic cycle length; B-cell leukemia/lymphoma |
| BCLS | basic cardiac life support |
| BCP | basic calcium phosphate; birth control pill; blue cone pigment; Blue Cross Plan; bromcresol purple |
| oxazin dyes | Similar to azin dye's except that one of the connecting N atoms is replaced by O; most important representatives are brilliant cresyl blue, orcein, litmus, and cresyl violet. (05 Mar 2000) |
|---|---|
| thiazin dyes | Similar to azin dye's except that one of the connecting N atoms is replaced by S; includes many important biological stains, especially in haematology, e.g., azure A, azure B, and methylene blue. (05 Mar 2000) |
| triphenylmethane dyes | A group of dye's that includes pararosanilin, as well as many others used in histology and cytology; employed as nuclear, cytoplasmic, and connective tissue stains; important in histochemistry as in the preparation of Schiff's reagent. (05 Mar 2000) |
| ketonimine dyes | Dye's in which the chromophore is ==C==NH connected to two benzene rings; alkylamino groups are added para to the methane carbon on both rings. The most important member for biological purposes is auramine O; an alternative formulation is as a diphenylmethane dye. (05 Mar 2000) |
| fluorescent dyes | Dyes that emit light when exposed to light. The wave length of the emitted light is usually longer than that of the incident light. Fluorochromes are substances that cause fluorescence in other substances, i.e., dyes used to mark or label other compounds with fluorescent tags. They are used as markers in biochemistry and immunology. (12 Dec 1998) |
| lissamine green dyes | Green dyes containing ammonium and aryl sulfonate moieties that facilitate the visualization of tissues, if given intravenously. They have mostly been used in the study of kidney physiology. (12 Dec 1998) |
| basic | 1. <chemistry> Relating to a base; performing the office of a base in a salt. Having the base in excess, or the amount of the base atomically greater than that of the acid, or exceeding in proportion that of the related neutral salt. Apparently alkaline, as certain normal salts which exhibit alkaline reactions with test paper. 2. <chemical> Said of crystalline rocks which contain a relatively low percentage of silica, as basalt. <chemistry> Basic salt, a salt formed from a base or hydroxide by the partial replacement of its hydrogen by a negative or acid element or radical.

| basic amino acid | An amino acid containing a second basic group (usually an amino group); e.g., lysine, arginine, ornithine. Synonym: dibasic amino acid. (05 Mar 2000) |
| basic anhydride | <chemical> A chemical (usually the oxide of a metal) which forms a base when it is mixed with water. (09 Oct 1997) |
| basic diet | A diet consisting mainly of fruits, vegetables, and milk (with minimal amounts of meat, fish, eggs, cheese, and cereals), which, when catabolised, leave an alkaline residue to be excreted in the urine. Synonym: acid-ash diet, basic diet. (05 Mar 2000) |
| basic electrical rhythm | A slow wave of depolarisation of smooth muscle from the fundus to the pylorus that coordinates gastric peristalsis and emptying. (05 Mar 2000) |
| basic esotropia | That type of esotropia not influenced by correction of refractive error. Synonym: basic esotropia. (05 Mar 2000) |
| basic exotropia | Exotropia in which the strabismus is the same for near and far vision. (05 Mar 2000) |
| basic fuchsin | A triphenylmethane dye whose dominant component is pararosanilin; an important stain in histology, histochemistry, and bacteriology. Synonym: diamond fuchsin. (05 Mar 2000) |
| basic fuchsin-methylene blue stain | <technique> A stain for intact epoxy sections; semi-thick sections of plastic-embedded tissues have nuclei stained purple; collagen, elastic lamina, and connective tissue are stained blue; mitochondria, myelin, and lipid droplets are stained red; cytoplasm, smooth muscle cells, axoplasm, and chrondroblasts are stained pink.
