| carbonyl cyanide m-chlorophenyl hydrazone | <chemical> A proton ionophore. It is commonly used as an uncoupling agent and inhibitor of photosynthesis because of its effects on mitochondrial and chloroplast membranes. Pharmacological action: uncoupling agents, ionophores. Chemical name: Propanedinitrile, ((3-chlorophenyl)hydrazono)- (12 Dec 1998) |
| carbonyl cyanide p-trifluoromethoxyphenylhydrazone | <chemical> A proton ionophore that is commonly used as an uncoupling agent in biochemical studies. Pharmacological action: ionophores, uncoupling agents. Chemical name: Propanedinitrile, ((4-(trifluoromethoxy)phenyl)hydrazono)- (12 Dec 1998) |
| carbonyl group | A group in which an oxygen atom is double-bonded to a carbon atom: O=C. The carbon atom then has two additional bonds to attach to the rest of the molecule. Organic molecules containing a carbonyl group are a very important, major group of compounds studied in the field of organic chemistry. (09 Oct 1997) |
| pig lung carbonyl reductase | <enzyme> Tetrameric carbonyl reductase; mw 24 kD; properties distinct from monomeric cr; it is mainly distributed in the mitochondria of the pig lung; exhibits very low substrate specificity for aromatic and aliphatic carbonyl compounds and catalyses the oxidation of secondary alcohols and aldehydes; activated 2-5 fold by fatty acids ddbj/embl/genbank d16511 Registry number: EC 1.1.1.- (26 Jun 1999) |
| administration, oral | The giving of drugs, chemicals, or other substances by mouth. (12 Dec 1998) |
| cancer, oral | Cancer of the mouth area. A sore in the mouth that does not heal can be a warning sign of oral cancer. A biopsy is the only to know whether as abnormal area in the oral cavity is cancer. Oral cancer is caused by tobacco (smoking and chewing) and alcohol use. Surgery to remove the tumour in the mouth is the usual treatment for patients with oral cancer. (12 Dec 1998) |
| candidiasis, oral | Infection of the mucous membranes of the mouth by a fungus of the genus candida. (12 Dec 1998) |
| canine oral papilloma | Warts affecting mucous membranes of young dogs; caused by a papillomavirus. (05 Mar 2000) |
| magnesia and alumina oral suspension | A mixture of magnesium hydroxide and variable amounts of aluminum oxide; used as an antacid. (05 Mar 2000) |
| pathology, oral | A dental specialty concerned with pathology of the oral cavity. (12 Dec 1998) |
| pharyngo-oral | Relating to the pharynx and the mouth; oropharyngeal. Origin: pharyngo-+ L. Os (or-), mouth (05 Mar 2000) |
| combination oral contraceptive | A mixture of a steroid having progestational activity and an oestrogen. (05 Mar 2000) |
| contraceptives, oral | Compounds, usually hormonal, taken orally in order to block ovulation and prevent the occurrence of pregnancy. The hormones are generally oestrogen or progesterone or both. (12 Dec 1998) |
| contraceptives, oral, combined | Fixed drug combinations administered orally for contraceptive purposes. (12 Dec 1998) |
