Mature and healthy male lesser bandicoot rats, Bandicota bengalensis (n = 40) were fed on bait (mixture of cracked wheat and powdered sugar in 98:2) containing different concentrations of triptolide (0, 0.15, 0.20 and 0.25% w/w) for 15 days in two-choice trials. Results revealed no significant effect of triptolide treatment on weights of vital organs after 30 and 60 days of treatment withdrawal. A significant (P ≤ 0.05) increase in plasma levels of TP, ALP, ACP, ALT and AST in response to stress induced in groups of rats treated with 0.20 and 0.25% triptolide was observed after 30 days of treatment withdrawal. No significant effect of treatment was observed on histomorphology of liver. A significant (P ≤ 0.05) effect of triptolide treatment was, however, observed on testicular function in the form of reduced diameter of seminiferous tubules and number of various spermatogenic cells indicating effect on spermatogenesis and spermiogenesis. The cell stages affected did not recover fully within 60 days period following treatment withdrawal. The present study suggests the potential of triptolide in the reproductive management of B. bengalensis by way of affecting testicular function.
选用40只成熟健康的雄性小板齿鼠(Bandicota bengalensis),在双选试验中,给它们喂食含有不同浓度雷公藤内酯醇(0、0.15、0.20和0.25% w/w)的诱饵(碎小麦和糖粉按98:2混合),持续15天。结果显示,在停药30天和60天后,雷公藤内酯醇处理对重要器官重量没有显著影响。在停药30天后,观察到用0.20%和0.25%雷公藤内酯醇处理的大鼠组因应激导致血浆中总蛋白(TP)、碱性磷酸酶(ALP)、酸性磷酸酶(ACP)、谷丙转氨酶(ALT)和谷草转氨酶(AST)水平显著(P≤0.05)升高。处理对肝脏组织形态学没有显著影响。然而,观察到雷公藤内酯醇处理对睾丸功能有显著(P≤0.05)影响,表现为曲细精管直径减小和各种生精细胞数量减少,表明对精子发生和精子形成有影响。停药后60天内,受影响的细胞阶段未完全恢复。本研究表明雷公藤内酯醇通过影响睾丸功能在小板齿鼠生殖管理方面具有潜在作用。
