The present lack of evidence for unique rodent germ-cell mutagens

A comparison of two rapid and inexpensive in vivo mammalian assays and the Ames Salmonella assay is presented for 61 agents; Acetylsalicylic acid; Acriflavine; Actinomycin D; 2(2-furyl)-3-(5-nitro-2-furyl)acrylamide (AF-2); Aflatoxin B1; 2-aminofluorene; Aminopterin; Aroclor 1254; Ascorbic acid; Azathioprine; Benzo(a)pyrene; 5-Bromo-2'-deoxyuridine; Busulphan, Butylated hydroxytoluene; Cadmium chloride; Caffeine; Calcium cyclamate; Chloral hydrate; Chloromycetin succinate; Codeine phosphate, Colchicine; Cycloheximide; Cyclophosphamide; DDT; 2,4-Diaminoanisole; Dibutylnitrosamine; 9, 10 Dimethyl-1,2-benzanthracene; 1,1-Dimethylhydrazine; Dimethylnitrosamine; Epinephrine; Ethyl methane sulphonate (EMS); 2-formylamino-4-(5-nitro-2-furyl)thiazole (FANFT); 2-(2-formylhydrazino)-4-(5-nitro-2-furyl)thiazole (FNT); Glucose, Griseofulvin; Hycanthone methane sulphonate; Hydroxyurea; 5-Iodo-2'-deoxyuridine; Lead acetate; Mechlorethamine; 3-Methylcholanthrene; Methyl mercury acetate; Methyl methane sulfonate (MMS); N-methyl-N-nitro-N'-nitrosoguanidine; Mitomycin C; Monosodium glutamate; 1-Naphthalamine; 2-Naphthalamine; Nitrofurazone; 4-Nitro-O-phenylene diamine; 4-Nitro-quinoline-1-oxide (4-NQO); Phenobarbitone; Procarbazine; Quinacrine dihydrochloride; Radiation (gamma-rays); Sodium chloride; Triethylene thiophosphoramide; Trimethyl phosphate; Tris(2-methyl-1-arizidinyl) phosphine oxide; Urethan; Vinblastine. The results support the concept of multiple assays for mutagenicity and show that some combinations of assays are superior to others.
