Cisplatin (CISP) is an efficacious anticancer agent used in chemotherapy, however, the constraint to its clinical utility is the stray organ toxicity including testicular damage linked to oxidative and inflammatory cascades. This study aimed to explore the protective effect of nucleosides‐rich extract from Cordyceps cicadae (NRCE) against CISP‐induced testicular damage in rats. Rats were subjected to prophylactic oral administration of NRCE (50, 100 and 400 mg/kg body weight/day) for 7 days prior to testicular toxicity induced by CISP (10 mg/kg, ip) and were sacrificed after 72 h post‐CISP injection. Cisplatin caused significant deficits in sperm count, viability and motility, testosterone and follicle stimulating hormone (FSH) compared to normal control. It depressed testicular activities of glutathione peroxidase (GSH‐Px), superoxide dismutase (SOD), catalase (CAT), total antioxidant content (TAC), whereas malondialdehyde (MDA) increased remarkably. CISP considerably increased tumor necrosis factor‐alpha (TNF‐α) and interleukin‐one beta (IL‐1β) with alterations in testis histology compared to normal control. Interestingly, NRCE pretreatment inhibited the CISP‐induced alterations in reproductive indices, restored the antioxidant activities in testes as well as inflammatory mediators and histology comparable to control. Our findings demonstrate that NRCE could prevent CISP testicular damage via inhibition of oxidative stress and pro‐inflammation in rats.

虫草富含核苷提取物对顺铂所致睾丸损伤的保护作用

顺铂 (CISP) 是一种用于化学疗法的有效抗癌剂,然而,其临床效用的限制是杂散器官毒性,包括与氧化和炎症级联反应相关的睾丸损伤。本研究旨在探讨富含核苷的虫草提取物 (NRCE) 对 CISP 诱导的大鼠睾丸损伤的保护作用。在 CISP (10 mg/kg, ip) 诱导睾丸毒性前 7 天对大鼠进行预防性口服 NRCE(50、100 和 400 mg/kg 体重/天),并在 CISP 后 72 小时处死注射。与正常对照相比,顺铂导致精子数量、活力和活力、睾酮和促卵泡激素 (FSH) 出现显着缺陷。它抑制了谷胱甘肽过氧化物酶(GSH-Px)的睾丸活性,超氧化物歧化酶 (SOD)、过氧化氢酶 (CAT)、总抗氧化剂含量 (TAC) 和丙二醛 (MDA) 显着增加。与正常对照相比,CISP 显着增加肿瘤坏死因子-α(TNF-α)和白细胞介素-一β(IL-1β),睾丸组织学发生改变。有趣的是,NRCE 预处理抑制了 CISP 诱导的生殖指标改变,恢复了睾丸中的抗氧化活性以及与对照相当的炎症介质和组织学。我们的研究结果表明,NRCE 可以通过抑制大鼠的氧化应激和促炎症来预防 CISP 睾丸损伤。与正常对照相比,CISP 显着增加肿瘤坏死因子-α(TNF-α)和白细胞介素-一β(IL-1β),睾丸组织学发生改变。有趣的是,NRCE 预处理抑制了 CISP 诱导的生殖指标改变,恢复了睾丸中的抗氧化活性以及与对照相当的炎症介质和组织学。我们的研究结果表明,NRCE 可以通过抑制大鼠的氧化应激和促炎症来预防 CISP 睾丸损伤。与正常对照相比,CISP 显着增加肿瘤坏死因子-α(TNF-α)和白细胞介素-一β(IL-1β),睾丸组织学发生改变。有趣的是,NRCE 预处理抑制了 CISP 诱导的生殖指标改变,恢复了睾丸中的抗氧化活性以及与对照相当的炎症介质和组织学。我们的研究结果表明,NRCE 可以通过抑制大鼠的氧化应激和促炎症来预防 CISP 睾丸损伤。
