            An evaluation of 6 short-term tests for detecting organic chemical carcinogens.

            A number of tests have been described which are thought to be capable of identifying carcinogens without using the actual induction of cancer as an endpoint. This study compared the performance of 6 such tests on a selection of 120 organic chemicals. The tests studies were: (1) mutation of Salmonella typhimurium; (2) cell transformation; (3) degranulation of endoplasmic reticulum; (4) sebaceous gland suppression; (5) tetrazolium reduction and (6) subcutaneous implant. A further 4 tests were examined briefly, but were not included in the complete evaluation. The chemicals were classified into carcinogens (58) and non-carcinogens (62) on the basis of published experimental data, and into 1 of 4 broad chemical classes. There was considerable variation between tests in their ability to predict carcinogenicity, with the cell-transformation test and the bacterial-mutation test being the most accurate (94% and 93% accurate respectively). These 2 tests were considered to be of general use in screening, since they were clearly more accurate than the others. Statistical consideration of various combinations of these tests showed that the use of cell transformation and bacterial mutation together, provide an advantage over the use of either test alone. The inclusion of the other 4 tests in a screening battery predictably resulted in a great increase in overall inaccuracy and loss of discrimination, even though the detection of carcinogens is improved. All the tests were shown to generate both false positive and false negative results, a situation which may be controlled by the use, where possible, of appropriate chemical-class controls, to identify the test which is optimal for the class of chemical under test. Structural analogy may have a part to play in the rapid detection of environmental carcinogens, and some general guidelines for its use are given.

              The mutagenic activity of 61 agents as determined by the micronucleus, Salmonella, and sperm abnormality assays.

              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.
