Endometrial hyperplasia complex is gynecological disorder characterized by morphological irregularities of glands shape and size. Antioxidant enzymes (AOE), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione reductase (GR), have an essential role in preventing oxidative damage in cell caused by reactive oxygen species (ROS). In this study, we examined the AO status in hyperplastic tissue of patients in menstrual cycle (follicular and luteal phase) and in postmenopause, as well as the relationship between sex hormones and AO parameters. The phase-related activity of GPx and GR in examined patients was significantly different than in healthy women. A significant negative correlation between FSH/LH level and GPx activiy was observed. Endometrial hyperplasias are considered as precancerous lesions and are treated either conservatively or surgicaly, and also by radiation therapy. Since the effects of these therapies are associated with AO and hormonal c...hanges, our results may contribute to the prediction of potential therapeutic efficacy and to selection of the most effective treatment for hyperplasia complex.
