Özet

We investigated the histopathological effects of methotrexate (MTX), a chemotherapeutic agent, and beta glucan (BG), an antioxidant, on rat testis. We used four groups of Sprague-Dawley male rats: MTX, MTX + BG, BG, and control. The MTX group was exposed to a single dose of MTX on the first day of experiment. The MTX + BG group was exposed to a single dose of MTX and BG on the first day of experiment followed by BG for 4 additional days. The BG group was exposed to BG for 5 days. The control group was given saline for 5 days. On day five, all animals were sacrificed and testicular tissue was evaluated for histopathology and the terminal deoxynucleotidyl transferase (TdT) deoxyuridine triphosphate nick-end labeling assay (TUNEL) was used to detect apoptosis. The apoptotic index (AI) and testicular damage increased in the MTX group compared to the other three groups. Histopathology was reduced in the MTX + BG group compared to the MTX group. Seminiferous tubule diameter was reduced in the MTX group compared to the BG group; we found no difference between control and BG groups. The thickness of th e germinal epithelium was reduced in the MTX group compared to the other groups. We found no difference in testicular weight among the groups. We compared body weight before and after the experiment; weights in the MTX and MTX + BG groups were significantly reduced compared to controls. In the control groups, we found a statistically significant increase in body weight, whereas there was no change in the BG group. We found that MTX causes deleterious effects on testicular tissue and that beta glucan may be protective.
