title: Factors affecting acetohexamide reductase activities in microsomes and cytosol from the kidney of male rats: age and castration.
abstract: Acetohexamide reductase activity in microsomes from the kidney of male rats increased markedly at puberty to approach the maximum level at 8 weeks of age; it was not detected until 4 weeks of age. Furthermore, castration suppressed effectively the activity in kidney microsomes at 8 weeks of age. These findings clearly indicate that the activity in kidney microsomes can be regulated by androgens. On the other hand, in cytosol from the kidney of male rats, a higher acetohexamide reductase activity was observed at all weeks of age tested. Castration had no significant effect on the activity in kidney cytosol.
