Abstract

Pretreatment of hamsters with benzo (a) pyrene (BaP) greatly increased the in vitro metabolism of BaP by lung microsomes from pregnant hamsters, and had less effect on the metabolism of BaP by liver microsomes. The production of various metabolites of BaP by lung microsomes was increased to different extents: 3-hydroxy-BaP (3-OH-BaP) was one of the major metabolites; the metabolic yields of 9, 10-dihydrodihydroxy-BaP (9, 10-diol) and 7,8-diol were increased more than that of the 4,5-diol. In the case of liver microsomes, only the yields of 9,10-diol and 7,8-diol were increased over the control levels. The presence of cyclohexene oxide in the incubation mixtures decreased the production of the diols. Basal-level enzyme activities in placental, fetal liver, and fetal skin microsomes in metabolizing BaP were very low. Pretreatment of pregnant hamsters with BaP induced BaP-metabolizing enzymes in fetal tissue 2-3 fold. © 1974.
