title: Effect of sizofilan, an immunomodulator, on hepatic microsomal mixed-function oxidase activities in rats.
abstract: Mixed-function oxidase activities of hepatic microsomal preparations from rats were examined after intraperitoneal administration of sizofilan (SPG), an immunomodulator. Repeated doses of SPG (3 mg/kg/12 hr, 4 times) depressed the hepatic cytochrome P-450 content and the activities of aminopyrine N-demethylase and aniline hydroxylase.
