| ferric oxide | A compound used as a colouring material. (05 Mar 2000) |
| 4-hydroxyaminoquinoline-1-oxide | <chemical> N-hydroxy-4-quinolineamine 1-oxide. A potent mutagen and carcinogen. It is a reduction product of 4-nitroquinoline-1-oxide. It binds with nucleic acids and inactivates both bacteria and bacteriophage. Pharmacological action: carcinogens, mutagens. Chemical name: 4-Quinolinamine, N-hydroxy-, 1-oxide (12 Dec 1998) |
| 4-nitroquinoline-1-oxide | <chemical> 4-nitroquinoline 1-oxide. A potent mutagen and carcinogen. This compound and its metabolite 4-hydroxyaminoquinoline-1-oxide bind to nucleic acids. It inactivates bacteria but not bacteriophage. Pharmacological action: carcinogens, mutagens. Chemical name: Quinoline, 4-nitro-, 1-oxide (12 Dec 1998) |
| 7,8-dihydro-7,8-dihydroxybenzo(a)pyrene 9,10-oxide | <chemical> 7,8,8a,9a-tetrahydrobenzo(10,11)chryseno (3,4-b)oxirene-7,8-diol. A benzopyrene derivative with carcinogenic and mutagenic activity. Pharmacological action: carcinogens, mutagens. Chemical name: Benzo(10,11)chryseno(3,4-b)oxirene-7,8-diol, 7,8,8a,9a-tetrahydro- (12 Dec 1998) |
| lead oxide | Has been used as an ingredient in external applications such as lead plaster. Synonym: lead oxide (yellow), litharge, massicot. (05 Mar 2000) |
| acridine yellow | A faintly yellow solution with strong bluish-violet fluorescence; used as a topical antiseptic and as a fluorescent stain in histology. Synonym: 5-aminoacridine hydrochloride, 9-aminoacridine hydrochloride. (05 Mar 2000) |
| acute yellow atrophy of the liver | A lesion in which there is extensive and rapid death of parenchymal cells of the liver, sometimes with fatty degeneration of the size of the organ; the necrosis may result from fulminant viral infection or chemical poisoning; associated with jaundice. Synonym: acute parenchymatous hepatitis, Rokitansky's disease. (05 Mar 2000) |
| brilliant yellow | An indicator dye that changes from yellow to orange or red at pH 6.4 to 8.0. (05 Mar 2000) |
| butter yellow | C6H5N:NC6H4N(CH3)2;a fat-soluble yellow dye (MW 225) that has hepatic carcinogenic action in experimental animals; used as an indicator of pH (red, at pH 2.9, yellow at pH 4.0). Synonym: dimethylaminoazobenzene, methyl yellow. (05 Mar 2000) |
| martius yellow | C10H6N2O5; 2,4-dinitro-alpha-naphthol;an acid dye used as a plasma stain in plant and animal histology, and as a light filter for photomicrography. Origin: Karl A. Martius, Ger. Chemist, *1920 (05 Mar 2000) |
