| Popis: | Selenium is an essential micro-element in animal diet due to its high antioxidative properties. As a part of selenocystein it is an important constituent of the glutathione peroxidase (GPx) enzyme, which has a big importance for cell protection from oxidative damage. The aim of the present work was the investigation of the selenopyran effect on the antioxidative state of the pig ovary. The experiment was conducted with 18 gilts of Danube white breed randomly divided into two groups between 120 - 228 days of age. The animals received equal basal diets without selenium additives. The experimental gilts were injected once per month intramuscularly with oil solution of preparation selenopyran (9-phenylsymmetrical octahydroselenoxanthene) ensured 0.1 mgSe/kg live weight. After slaughtering, the ovaries were used for histological analysis and estimation of the selenium content in ovarian tissue by the atomic absorption spectroscopy method. The GPx activity in ovary homogenates using the colorimetric assay kit (BioVision) was measured. The expression of γ-glutamyl transpeptidase (GGT) in ovaries by immunochistochemical method was estimated. The selenopyran treatment leads to significant (P0.05) in ovarian tissue. Enhancement of GPx activity in the ovaries of experimental group was observed (142.61±6.6 versus 122.28±3.4U/gP, P |
