Abstract
Summary
Rat liver microsomes isolated from rats pretreated orally with acetone or isopropanol possessed an enhanced capacity to bind 14CCl4 and 14CHCl3 covalently and to demethylate DMN. The N-demethylation of ethylmorphine was unchanged by this pretreatment. Since there was no increase in the level of microsomal protein, and microsomal cytochrome P-450 or the activity of NADPH-cytochrome c reductase, the mechanism of this enhanced metabolism remains unclear.
