| tubocurarine chloride | C38H44Cl2N2O6-5H 2O; d-Tubocurarine chloride;an alkaloid (obtained from the stems of Chondodendron, particularly C. Tomentosum) that blocks the action of acetylcholine at the myoneural junction by occupying the receptors competitively; also blocks ganglionic transmission and releases histamine; used to produce muscular relaxation during surgical operations.

| ethyl chloride | <chemical> A gas that condenses under slight pressure. Because of its low boiling point ethyl chloride sprayed on skin produces an intense cold by evaporation. Cold blocks nerve conduction. Ethyl chloride has been used in surgery but is primarily used to relieve local pain in sports medicine. Pharmacological action: anaesthetics, local. Chemical name: Ethane, chloro- (12 Dec 1998) |
| ethylmercuric chloride | <chemical> A highly toxic compound used as a fungicide for treating seeds. Pharmacological action: fungicides, industrial. Chemical name: Mercury, chloroethyl- (12 Dec 1998) |
| undecoylium chloride | Acylcolaminoformylmethylpyridinium chloride;a topical antiseptic. (05 Mar 2000) |
| undecoylium chloride-iodine | A complex of iodine with undecoylium chloride; a cationic detergent used topically as a germicidal agent. (05 Mar 2000) |
| zinc chloride | ZnCl2;formerly used as a caustic for the removal of cutaneous cancers, nevi, etc., and in weak solution in the treatment of gonorrhoea and conjunctivitis. Synonym: butter of zinc. (05 Mar 2000) |
| ferric chloride | An astringent and styptic. (05 Mar 2000) |
| ferric chloride reaction of epinephrine | An intense emerald green colour in a neutral or slightly acid solution of epinephrine when ferric chloride is added to it; a reaction typical of catechols. (05 Mar 2000) |
| ferriheme chloride | <physiology> A substance, in the form of reddish brown, microscopic, prismatic crystals, formed from dried blood by the action of strong acetic acid and common salt; called also Teichmann's crystals. Chemically, it is a hydrochloride of haematin. The obtaining of these small crystals, from old blood clots or suspected blood stains, constitutes one of the best evidences of the presence of blood. Origin: Gr. Blood. Source: Websters Dictionary (01 Mar 1998) |
| ferriporphyrin chloride | <physiology> A substance, in the form of reddish brown, microscopic, prismatic crystals, formed from dried blood by the action of strong acetic acid and common salt; called also Teichmann's crystals. Chemically, it is a hydrochloride of haematin. The obtaining of these small crystals, from old blood clots or suspected blood stains, constitutes one of the best evidences of the presence of blood.

| 3-chloro-D-alanine hydrogen chloride-lyase | <enzyme> Pseudomonas putida enzyme; forms cysteine from 3-chloro-d-alanine and hydrogen sulfide Registry number: EC 4.5.- Synonym: cahc-lyase, 3-chloro-d-alanine chloride-lyase (deaminating) (26 Jun 1999) |
| lithium chloride | <chemical> A salt of lithium that has been used experimentally as an immunomodulator. Pharmacological action: adjuvants, immunologic, antimanic agents. Chemical name: Lithium chloride (LiCl) (12 Dec 1998) |
| Abbe test plate | <equipment> A long, wedge-shaped coverslip about 0.20 mm thick at one end and 0.10 to 0.12 mm at the other end coated chemically with a silver film on which are ruled horizontal lines. at each variation in thickness of 0.01 mm there are vertical lines. By means of oblique illumination and by focusing on different portions of the plate, it is possible to determine the optimum coverslip thickness for any objective and also, for microscopes with drawtubes, the tube length for best objective performance. The approximate freedom from spherical and chromatic aberrations can also be estimated. Small isolated bits of silver near the edges of the lines form good objects for the star test (05 Aug 1998) |
| acetone test | A test for ketonuria; the suspected urine is shaken up with a few drops of sodium nitroprusside, and strong ammonia water is then gently poured over the mixture; if acetone is present, a magenta ring forms at the line of contact; tablets containing sodium nitroprusside and alkali are now more commonly used.

| achievement test | A standardised test used to measure acquired learning, e.g., competence in a specific subject area such as reading or arithmetic, in contrast to an intelligence test which is a useful index of potential ability or learning. (05 Mar 2000) |
