About 300 carcinogens and non-carcinogens of a wide variety of chemical types have been tested for mutagenicity in the simple Salmonella/microsome test. The test uses bacteria as sensitive indicators for DNA damage, and mammalian liver extracts for metabolic conversion of carcinogens to their active mutagenic forms. Quantitative mutagenicity data from linear dose-response curves are presented: potency varies over a 10(6)-fold range. There is a high correlation between carcinogenicity and…

Detection of mutagenic impurities in carcinogens and noncarcinogens by high-pressure liquid chromatography and the Salmonella/microsome test.

The mutagenicity of 7-hydroxy-2-acetylaminofluorene, a noncarcinogen in the standard animal carcinogenicity tests, is shown to be due to a small amount of impurity, which is probably the potent carcinogen 2-actylamin ofluorenes.

The goal of the work to be described in this review has been to develop sensitive and reliable mammalian cell systems that could be useful as part of a test battery for the screening of chemicals.

It is concluded that the use of the Salmonella mutagenicity assay is warranted for the identification of carcinogens, but not for noncarcinogens.

It seems of great importance to develop appropriate methods to study induced mutations of polygenic systems and to get a better understanding of the properties of these genetic systems and an evaluation of the risk connected with induced mutations in polygenes.

The Salmonella Mutagenicity Test: An Overview

The Salmonella test is currently the most widely used short-term test for screening environmental mutagens and carcinogens. It is in use in more than 2000 government, industrial and academic

A review of several studies comparing mutation induction and tumor induction indicates that the Ames test can be useful in screening large numbers of chemicals, but the true correlation coefficient is only about 80% when compared to tumor responses in mice and rats.

Mammalian Cell Mutagenesis: Relevance For Detection of Environmental Mutagens/Carcinogens

Overall mutagenicity in mammalian cells correlated well to that obtained with the Ames assay, but some qualitative and quantitative differences exist between two assays.
