Sažetak
The aim of this study was to investigate the differences in the level of antioxidative protection and lipid peroxidation in the testes and different parts of the epididymis in reproductive boars. The study was performed on five boars of the Swedish landrace breed, 10 months of age. Tissue samples were taken of the testes and the head, body and tail of the epididymis. In the obtained supernatants of the homogenized tissues, the activities of glutathione peroxidase (GSH- Px), glutathione reductase (GSH- RD), superoxide dismutase (SOD), gamma glutamyl transferase (GGT), and concentration of malondialdehyde (MDA) were determined. Significantly higher activities of GSH- Px and GSH- RD (p < 0.05) were found in the testes than in the epididymis. The testes were found to have a significantly higher activity of SOD than the head and tail of the epididymis (p < 0.05). The MDA concentration in the head of the epididymis was significantly higher than in the testes, body and tail of the epididymis (p < 0.05). Simultaneously, the MDA concentration in the testes, was significantly higher than in the body and the tail of the epididymis (p < 0.05). In epididymis tail, a significantly higher activity of GGT was recorded than in the testes and other parts of the epididymis (p < 0.05). The results of the current study indicate the physiological importance of antioxidative enzymes in tissues of the reproductive system in boars. Furthermore, the obtained results may serve to better understand the mechanisms of male infertilityvand to improve boar semen storage.
