Rats were immunized by intraperitoneal injection of ovalbumin emulsified with Freund incomplete adjuvant, and then the effect of an intravenous challenge with ovalbumin on hepatic drug-metabolizing enzyme activities was examined. The cytochrome P-450 content and ethylmorphine N-demethylase, benzphetamine N-demethylase, arylhydrocarbon hydroxylase and 7-ethoxycoumarin O-deethylase activities significantly decreased in rats treated with ovalbumin compared with control groups treated with saline, whereas there was no significant reduction in cytochrome b5, NADPH-cytochrome c reductase and NADH-cytochrome c reductase.
