5 alpha-androstane-3 beta,17 beta-diol hydroxylase ( 3 beta-diol ohase ) , a form of cytochrome p-450 whose main function is thought to be the elimination of dihydrotestosterone ( dht ) from its target tissues , was found in the central nervous system ( cns ) of both male and female rats at a level which is at least 300-fold higher than any other p-450 catalyzed steroid hydroxylase in the brain .
