目的 对杜仲补天素片药效进行二次开发,新增其治疗男性不育症的功效,为其临床用于治疗男性不育症提供实验基础。方法 将雄性小鼠随机分为杜仲补天素片高、中、低剂量(0.72、0.36、0.18 g/kg)组,对照组,阳性药生精胶囊组,观察各组雄性小鼠免疫器官及性腺器官脏器指数、抗疲劳作用、生育力作用。将雄性SD大鼠随机分为杜仲补天素片高、中、低剂量(0.504、0.252、0.126 g/kg)组、对照组,模型组,阳性药生精胶囊组,观察各组雄性大鼠脏器指数、睾丸病理结构的变化,测定各组雄性大鼠血清性激素水平及血清氧化反应指标以及生育力;进行HE染色,观察各组雄性大鼠的睾丸形态学结构。结果 杜仲补天素片通过提高幼龄雄性小鼠免疫功能和性腺器官脏器指数,延长游泳存活时间,具有抗疲劳作用,从而促使雌性小鼠受孕率上升。通过增加模型大鼠的体质量,提高性器官及肾脏指数,增加血清性激素促卵泡激素(FSH)、促黄体激素(LH)、睾酮(T)、雌二醇(E2)的量,降低血清丙二醛(MDA)量,提高血清超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)水平,产生抗氧化损伤作用并改善睾丸病理形态损伤,从而促使雌性大鼠受孕率及平均产仔数上升,发挥抗腺嘌呤致大鼠生精功能障碍作用。结论 杜仲补天素片对雄性动物具有促生育、改善生育及逆转受损生殖能力的作用,为杜仲补天素片的临床应用提供实验基础。

[Abstract]
Objective To develop Duzhong Butiansu Tablet (DBT) for the second time and add the effect on male infertility, so as to provide an experimental basis for the treatment of male infertility. Methods The male mice were randomly divided into five groups:high, medium, and low dose groups of DBT, control group, and positive drug group. The immune and gonadal organ index, anti-fatigue effect and fecuudity of each group were observed. The male SD rats were randomly divided into six groups:high, medium, and low dose groups of DBT, control group, model group, and positive drug group. The changes of organ index, testicular pathological structure, levels of serum sex hormones and effects of serum oxidative stress and fecuudity were measured. The morphological structure of testes was observed by HE staining. Results By improving the immune function and sex organ index of young male mice, DBT had the anti-fatigue effect on extending the swimming survival time, which would promote the increase of pregnancy rate of female mice. By increasing the weight of model rats, DBT could increase sexual organs and kidney indexes, improve contents of serum sex hormones FSH, LH, T, and E2 and reduce content of MDA in serum, and has anti-oxidant effect of increasing serum SOD and GSH-Px levels, and improves the testicular pathological damage, thus contributs to increase the pregnancy rate of female rats and the average litter size and production of anti-rat spermatogenic dysfunction induced by adenine effect. Conclusion DBT can improve the growth and reproductive capacity to reverse the impairment effects on male animal, and provide experimentalbasis for the clinical research.
