Promoting effects of dimethylarsinic acid on N-butyl-N-(4-hydroxybutyl)nitrosamine-induced urinary bladder carcinogenesis in rats.

abstract：:The genotoxic effects of intragastrically administered benzo[a]pyrene (BaP) were studied in isolated rat liver and intestinal cells. We found that BaP was unable to induce unscheduled DNA synthesis in rat parenchymal liver cells in vivo. In contrast, alkaline elution showed that at 5 h after administration of BaP a co...
