| chloroethylene | <chemical> A gas that has been used as an aerosol propellant and is the starting material for polyvinyl resins. Toxicity studies have shown various adverse effects, particularly the occurrence of liver neoplasms. Pharmacological action: carcinogens. Chemical name: Ethene, chloro- (12 Dec 1998) |

| chlorofluorocarbon | A family of chemicals composed primarily of carbon, hydrogen, chlorine, and fluorine. Used principally as refrigerants and industrial cleansers. Chlorofluorocarbons have the tendency to destroy the Earth's protective ozone layer. (05 Dec 1998) |
| chlorofluorocarbons | A series of hydrocarbons containing both chlorine and fluorine. These have been used as refrigerants, blowing agents, cleaning fluids, solvents, and as fire extinguishing agents. They have been shown to cause stratospheric ozone depletion and have been banned for many uses. (12 Dec 1998) |
| chloroform | A heavy, clear colourless liquid with a strong ether-like odour, once used for anaesthesia, but now obsolete. (27 Sep 1997) |
| chloroformism | Habitual chloroform inhalation, or the symptoms caused thereby. (05 Mar 2000) |
| chlorofucin | Synonym: chlorophyll c. Origin: chloro-+ L. Fucus, G. Phykos, red lichen, + -in (05 Mar 2000) |
| chlorogenic acid | <chemical> A naturally occuring phenolic acid which is a carcinogenic inhibitor. It has also been shown to prevent paraquat-induced oxidative stress in rats. Chemical name: Cyclohexanecarboxylic acid, 3-((3-(3,4-dihydroxyphenyl)-1-oxo-2-propenyl)oxy)-1,4,5-trihydroxy-, (1S-(1alpha,3beta,4alpha,5alpha))- (12 Dec 1998) |
| chloroguanide | <chemical> A biguanide compound which has little antimalarial activity until metabolised in the body to the active antimalarial agent cycloguanil. The usefulness of proguanil is limited by the rapid development of drug resistance by the malarial parasite. The hydrochloride is used for the casual prophylaxis of falciparum malaria, to suppress other forms of malaria, and to reduce transmission of infection Pharmacological action: antimalarials, antimetabolites. Chemical name: Imidodicarbonimidic diamide, N-(4-chlorophenyl)-N'-(1-methylethyl)- (12 Dec 1998) |
| chloroguanide hydrochloride | 1-(p-chlorophenyl)-5-isopropylbiguanide monohydrochloride;an antimalarial drug. Synonym: chlorguanide hydrochloride, proguanil hydrochloride. (05 Mar 2000) |
| chlorohemin | <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) |
| chlorohemin crystals | Rhombic crystals of hemin; used in microscopic detection of blood. See: hemin. Synonym: chlorohemin crystals. (05 Mar 2000) |
| chlorohydrins | Any of the compounds derived from a group of glycols or polyhydroxy alcohols by chlorine substitution for part of the hydroxyl groups. (12 Dec 1998) |
| chloroleukaemia | Synonym: chloroma. Origin: chloro-+ G. Leukos, white, + haima, blood (05 Mar 2000) |
| chloroma | <tumour> A condition characterised by the development of multiple localised green masses of abnormal cells (in most instances, myeloblasts), especially in relation to the periosteum of the skull, spine, and ribs; the clinical course is similar to that of acute myeloid leukaemia, although the tumours may precede the findings in blood and bone marrow; observed more frequently in children and young adults. See: granulocytic sarcoma. Synonym: chloroleukaemia, chloromyeloma. Origin: chloro-+ G. -oma, tumour (05 Mar 2000) |
| chloromercuribenzoates | <chemical> Chloride and mercury containing derivatives of benzoic acid. Some of these are commonly used as sulfhydryl reagents in biochemical studies. Pharmacological action: enzyme inhibitors, sulfhydryl reagents. (12 Dec 1998) |
