Differences in the covalent binding of benzo[a]pyrene, safrole, 1'-hydroxysafrole, and 4-aminobiphenyl to DNA of pregnant and non-pregnant mice.


The effects of pregnancy on the covalent binding of several carcinogens to DNA were investigated in mice. Non-pregnant or timed-pregnant (18th day of gestation) ICR mice of similar age were treated with benzo[a]pyrene (BP, 200 mumol/kg), safrole (600 mumol/kg), 1'-hydroxysafrole (400 mumol/kg), 4-aminobiphenyl (4-ABP, 800 mumol/kg), or trioctanoin (4 ml/kg… (More)
