Abstract

Cadmium chloride (CdCl2) pretreatment produced a marked decrease in the activity of the hepatic microsomal mono-oxygenase enzyme systems in male New Zealand white rabbits. Following in vivo sub-lethal doses (6 mg/kg i.p.) of CdCl2 for 5 days, significant decreases in the levels of cytochrome P-450 and in the microsomal metabolism of a range of substrates were observed. Pretreatment of rabbits with phenobarbitone significantly increased the levels of cytochrome P-450 and also increased the metabolism of all the substrates used. The inhibition pattern produced by CdCl2 remained the same in control and PB-pretreated rabbits. CdCl2 treatment did not result in any change in the levels of cytochrome b5 or cytochrome-c-reductase.
