Changes in the Lipid Peroxidation-Antioxidant Protection System in Women with Ovarian Hyperandrogenism at Different Periods of Reproductive Age

摘要

We studied changes in LPO processes and antioxidant protection system in women with ovarian hyperandrogenism at various periods of reproductive age 18-45 years. An age-related decrease in total antioxidant activity and accumulation of secondary LPO products, ketodiens and coupled trienes, were found; these changes were accompanied by an increase in the level of superoxide dismutase and a decrease in the concentrations of reduced glutathione, alpha-tocopherol, and retinol. Women of early reproductive age (18-35 years) with hyperandrogenism were characterized by increased content of oxidized glutathione accompanied by a decrease in the level of alpha-tocopherol and retinol in comparison with the control group. In women of late reproductive age (35-45 years) with hyperandrogenism, increased superoxide dismutase activity in comparison with the control group was revealed.
