Abstract:

: Cisplatin (CIS) is widely applied for its antihematological malignancies properties and as antisolid tumors drugs. However, it could cause testicular damage related with oxidative stress and testosterone synthesis disorder. Studies reported that grape seed procyanidins extract (GSPE) could improve CIS induced-testes lesion via scavenging free radicals in animals, although its mechanisms were unclear. Therefore, the purpose of the present study was to explore the antagonistic mechanisms of GSPE on CIS-induced testes lesion. Rats were treated with 10 mg/kg by weight CIS by intraperitoneal injection singly on the 11th day, and different doses of GSPE were administrated via intragastric gavage for 15 days consecutively. The results showed that GSPE improved the pathological changes of testicular tissue, and the decreased concentrations of testosterone in serum induced by CIS. GSPE inhibited CIS-induced oxidative/nitrative stress, as well as increased the mRNA and protein levels of testosterone synthetase in rat testes. In conclusion, the main protection exerted by GSPE on CIS-induced testicular toxicity is related to its effects includingsuppressing oxidative/nitrative stress and up-regulating expression of testosterone synthetase.
