Various plant compounds or extracts are incorporated into the postmitochondrial (S9) activation system and their ability to inhibit the mutagenicity of model precarcinogens is determined. However, such a protocol suffers from a number of ma

These rats had a lower incidence of large bowel neoplasms than animals given MAM acetate alone. Reduction of the tumor i

In mammalian cells, the concentration of GSH is often very high (in the millimolar range); most of the intracellular GSH exists in the thiol form, although mix

Studies have been carried out in vitro with the Ames test (reverse mutations on TA98, TA100, and TA104 strains) and sister chromatid exchanges assay (SCE) in human lymphocytes. NAC inhibits diesel genotoxicity in both assays. NAC also inhibits
