title: [Induction of cytochrome P-450 in rat liver microsomes by perfluorodecalin].
abstract: Perfluorodecalin was incorporated into phospholipid liposomes and injected intraperitoneally in various dozes. The maximal cytochrome P-450 induction is reached 48 hours after perfluorodecalin injection. Cytochrome P-450 content increases 4 times after perfluorodecalin injection in dose of 0.6 ml/kg in homogenate, and 6 times after perfluorodecalin injection in a dose of 0.4 ml/kg in microsomes. Phenobarbital and perfluorodecalin induce several cytochrome P-450 isozymes and cause the appearance of a new isozyme with mass 56 kD absent in microsomes of intact CBA mice. Perfluorodecalin induction strongly increased the rate of NADPH-dependent aminopyrine nN-demethylation (6-7 times per mg of microsomal protein and 1.5 times per nmol cytochrome P-450). The rate of NADPH-dependent hydroxylation of aniline was not affected by perfluorodecalin induction.
