Cyclophosphamide (CPA) is an anticancer drug used in the treatment of a variety of neoplastic lesions. On the other hand, treatment with CPA was accompanied by different toxic effects on different body organs. The present work was conducted to study the effect of fenugreek seed extract on histomorphometrical and ultrastructural changes induced by CPA in testes of albino mice. Twenty animals were given CPA (7.0 mg/kg body weight) three times/week orally for 8 weeks and were killed after 4 and 8 weeks. Testis of CPA-treated mice showed many histological alterations including appearance of irregular seminiferous tubules, reduction in the number of all spermatogenic cells, degeneration of Leydig cells and appearance of intertubular hemorrhage. Concerning the ultrastructural changes, abnormalities in spermatogonia (A and B), spermatocytes, round and elongated spermatids were observed. Degenerated Sertoli cells and degenerated interstitial tissue with abnormal Leydig cells were also seen. Moreover, administration of CPA to animals significantly increased malondialdehyde (MDA, lipid peroxidation marker) and decreased superoxide dismutase (SOD) and catalase (CAT). These changes were time-dependent. Treating animals with CPA and fenugreek seed extract (0.4 g/kg body weight) led to an improvement in the histological and ultrastructural pictures of the testis together with reduction in the level of serum MDA and increase in the activities of serum SOD and CAT. In conclusion, the results of the present work indicated that fenugreek had ameliorative effect against testis damage induced by CPA and this may be mediated by its potent antioxidant activities.
环磷酰胺(CPA)是一种用于治疗多种肿瘤性病变的抗癌药物。另一方面,CPA治疗会对不同身体器官产生不同的毒性作用。本研究旨在探讨胡芦巴籽提取物对CPA诱导的白化小鼠睾丸组织形态计量学和超微结构变化的影响。20只动物每周口服3次CPA(7.0毫克/千克体重),持续8周,并在4周和8周后处死。经CPA处理的小鼠睾丸出现许多组织学改变,包括生精小管不规则、所有生精细胞数量减少、睾丸间质细胞变性和管间出血。关于超微结构变化,观察到精原细胞(A和B型)、精母细胞、圆形和长形精子细胞出现异常。还可见支持细胞变性和间质组织变性以及睾丸间质细胞异常。此外,给动物施用CPA会显著增加丙二醛(MDA,脂质过氧化标志物),并降低超氧化物歧化酶(SOD)和过氧化氢酶(CAT)。这些变化具有时间依赖性。用CPA和胡芦巴籽提取物(0.4克/千克体重)治疗动物可改善睾丸的组织学和超微结构图像,同时降低血清MDA水平,提高血清SOD和CAT活性。总之,本研究结果表明,胡芦巴对CPA诱导的睾丸损伤具有改善作用,这可能是由其强大的抗氧化活性介导的。
