Objective:
To evaluate the protective effect of interleukin 10 (IL-10) on biochemical and histopathologic changes in experimental testicular ischemia or reperfusion injury (RI) in rats.
Methods:
Sprague-Dawley rats were randomly divided into 3 groups, each containing 7 rats; sham-control, I-R/untreated group, and I/R treated with IL-10. The ischemia period was 6 hours, and orchiectomy was performed after 1 hour of detorsion. IL-10 was given intraperitoneally in a period of 10 minutes before reperfusion. In all groups, ipsilateral orchiectomies were performed to make histologic examination and biochemical analysis such as malondialdehyde, glutathione peroxidase, and myeloperoxidase (MPO).
Results:
IL-10 treatment significantly decreased the I-R-induced elevation in testes malondialdehyde levels. In the I-R/IL-10-treated group, testes glutathione peroxidase levels were increased compared with the I-R/untreated group rats. MPO activities were significantly increased in the testes tissues of the I-R/untreated group. However, in the I-R/IL-10-treated group, MPO levels significantly decreased. Histopathologically, in the I-R/untreated group rats, edema, congestion, hemorrhage among seminiferous tubules, and necrosis of the germinal cells were predominant features in sections. The testicular injury score was lower in the IL-10-treated group rats compared with the I-R/untreated group.
Conclusion:
IL-10 might play a protective role in reducing reperfusion injury.
