This study investigated whether goji berry extract (GBE), a known antioxidant, reduces ischemic reperfusion injury when administered to rats exposed to experimental testis torsion. A total of 32 Sprague-Dawley male rats were randomized into 4 groups, including the control (sham), goji, torsion, and torsion-goji groups. The treatment groups received intraperitoneal GBE prior to torsion. The left testes of the animals were subjected to torsion via 5 hours of ischemia and 6 hours of reperfusion. TAC (total antioxidant capacity), TOS (total oxidant status) and OSI (oxidative stress index) levels were calculated. Approximately 5-μm-thick sections were stained with hematoxylin-eosin (H&E) and examined under a light microscope. Statistical analyses were performed with the SPSS 15 software package. The mean serum TAC level was significantly increased in Groups 2 and 4 compared with Groups 1 and 3 in biochemical analyses (for both P < 0.001). The mean serum TOS level was significantly increased in Group 3 compared with Groups 1, 2, and 4 (P < 0.001, P < 0.001, and P = 0.003, respectively). Comparison of the groups with regard to histopathological examination revealed that Group 4 exhibited a significantly higher rate of hemorrhage and congestion compared with Groups 1 and 2 (P = 0.038). The groups did not differ significantly with respect to degeneration. Ischemic reperfusion injury associated with testis torsion was reduced by the antioxidant effect of GBE. Further experimental and clinical studies are needed to confirm the agent's efficacy for this indication. |
