Animals were treated with 7.5 mmol of VCH/kg/day i.p. for 10 days or with inducing agents as described in Materials and Methods,and livers were harvested for microsomal preparation 24 h following the last dose. Microsomes (0.75 mg of protein) were incubated for 10 min with 1 mM 1,2-VCHE.
↵2-a Data represent the mean of two experiments, each performed in triplicate with pooled microsomes. Relative S.D. was <8%.
