Protective effect of ebselen on experimental testicular torsion and detorsion injury

Ebselen is used as a drug in clinical trials against stroke, reperfusion injury with anti‐atherosclerotic and renoprotective effects. The aim of this study is to investigate the protective effect of ebselen, on torsion/detorsion (T/D)‐induced biochemical and histopathological changes in experimental testicular ischaemia/reperfusion injury. A total of 28 male Wistar Albino rats were divided into four groups: group 1(sham‐operated group, n = 7), group 2(ebselen group, n = 7), group 3(torsion/detorsion + saline, n = 7) and group 4(T/D + 10 mg kg^?1 ebselen group, n = 7). The tissue homogenate samples were used for immediate nitric oxide (NO), malondialdehyde (MDA), superoxide dismutase, catalase and glutathione measurement. Testes in all groups were evaluated for the biochemical assay and histopathological examinations. To evaluate spermatogenesis, Johnsen scoring system was used. Testicular tissue MDA and NO levels in group 3 were significantly higher than in group 1 and 4. In histological evaluation of the testicular tissues, ebselen administration improved tubular histology significantly compared with T/D group. Significant increase in histological score was observed in the testis of group 3 compared with group 1 and 2. Histological score in group 4 significantly decreased compared with group 3. Johnson score was significantly lower in T/D group compared with all other three groups, ebselen administration increased the score significantly compared with T/D group. Ebselen reduced oxidative biochemical and histopathological damage in our testicular T/D rat model.
