Mutagenic activation of 3-amino-1,4-dimethyl-5H-pyrido(4,3-b)indole(Trp-P-1) and 3-amino-1-methyl-5H-pyrido(4,3-b)indole (Trp-P-2) by primary cultures of adult rat hepatocytes: effect of Aroclor induction in vitro.

Abstract excerpt

The mutagenic activation of tryptophan pyrolysis products, Trp-P-1 and Trp-P-2, was studied in a Salmonella TA98/hepatocyte mutagenesis assay. Adult rat hepatocytes in primary culture were either untreated or induced by the addition of Aroclor 1254 (2 micrograms/ml) 18-20 h before the mutagenesis test which was performed at day 1 and at day 2 after the isolation of hepatocytes. The mutagenic activation of Trp-P-1...
