Abstract

We studied in the Wistar rat the effect of bilateral ovariectomy and of the administration of estradiol (E2) alone or together with medroxyprogesterone (MPA) on the lipid peroxidation (MDA) and the enzymatic (SOD and catalase) and non-enzymatic (vitamins A and E) antioxidant systems. At 15 days after castration, we observed no variations in the lipid peroxidation levels (MDA), with there being a slight increase in vitamins A and E (p<0.05), catalase (p<0.01), and SOD (n.s.) activity. The addition of estradiol led to a decline (n.s.) in the MDA values and in the catalase and SOD activity, with no modification of the vit. A and E concentrations. The combined (E2+MPA) therapy did not modify the results obtained with E2 alone, although the catalase decline did now reach significance (p<0.05).
