studies with microsomal preparations containing cytochrome p-448 , induced by 3-methylcholanthrene or beta-naphthoflavone , revealed that this hemeprotein was more susceptible to direct degradation by bis ( tri-n-butyltin ) oxide than was the uninduced or phenobarbital-induced forms of cytochrome p-450 .
