Abstract excerpt
Earlier studies have established that the rodent bladder carcinogen o-anisidine (OA) gives negative results in all of the standard rodent genetic toxicity assays. In the present study, a single oral administration of the maximum tolerated dose level (750 mg/kg) of OA to B6C3F1 mice yielded negative results in 32P-post-labelling assays of bladder and liver DNA (24 h after dosing). Likewise, 14C-ring-labelled OA...
