Abstract |
Ornithine decarboxylase (ODC), the rate-limiting enzyme in polyamine synthesis, was significantly induced in female rat liver following oral administration of the pesticide, mirex. After dual oral exposure (120 mg/kg; 21 and 4 hrs. prior to sacrifice) induction of ODC activity in rat liver cytosol was 70-fold as compared to controls. A single oral dose of mirex (180 mg/kg) induced hepatic ODC activity 55-fold over controls. The time-course study indicated that maximal induction of ODC activity after a single oral dose of mirex was at 36 hours post-dosing. Though the exact mechanisms is still unclear, it appears that sex could be a pre-disposing factor in the induction of ODC activity in rat liver. Mirex is an unusually strong and long lasting inducer of rat hepatic ODC activity. (Copyright (c) 1990 VCH Publishers, Inc.) |
