Abstract:
OBJECTIVE: To study the protective effect of Qilin Pills (QLP) on the reproductive function of rats with oligoasthenospermia (OAS) induced by tripterygium glycosides. METHODS: Twenty-eight male SD rats were randomly divided into a normal control, an OAS model control, a low-dose QLP, and a high-dose QLP group of equal number. OAS models were made in the latter three groups by intragastrical administration of tripterygium glycosides at 40 mg per kg of the body weight per day, and meanwhile the animals in the low- and high-dose QLP groups were treated with QLP at 1.62 and 3.24 g per kg of the body weight per day, respectively, while those in the OAS model group with normal saline, all for 30 consecutive days. Then all the rats were executed for obtaining the testis weight, testis viscera index, epididymal sperm concentration and motility, reproductive hormone levels, and antioxidation indexes and observation of the histomorphological changes of the testis tissue by HE staining. RESULTS: After 30 days of intervention, the low- and high-dose QLP groups, as compared with the OAS model controls, showed significantly improved epididymal sperm concentration (［14.57 ± 3.95］ and ［39.71 ± 11.31］ vs ［4.71 ± 1.25］ ×10⁶/ml, P <0.05) and motility (［3.71 ± 1.11］ and ［4.29 ± 1.80］ vs ［0.57 ± 0.53］%, P <0.05), increased levels of sex hormone binding globulin (SHBG) (［94.83 ± 11.17］ and ［88.05 ± 9.21］ vs ［56.74 ± 8.29］ nmol/L, P <0.05) and free testosterone (FT) (［27.27 ± 3.63］ and ［32.80 ± 2.51］ vs ［22.81 ± 2.75］ nmol/L, P <0.05), decreased level of follicle-stimulating hormone (FSH) (［1.49 ± 0.62］ and ［1.12 ± 0.83］ vs ［1.71 ± 0.52］ mIU/ml, P <0.05), but no significant change in the total testosterone (TT) level. Meanwhile, the level of superoxide dismutase (SOD) was markedly elevated in the low- and high-dose QLP groups in comparison with the OAS model control group (［277.14 ± 15.84］ and ［299.60 ± 20.83］ vs ［250.04 ± 31.06］ U/ml, P <0.05) while that of reactive oxygen species (ROS) remarkably reduced (［397.61 ± 62.71］ and ［376.84 ± 67.14］ vs ［552.20 ± 58.07］ IU/ml, P <0.05). HE staining showed that QLP intervention significantly increased the layers and quantity of spermatogenic cells in the testicular seminiferous tubules of the OAS rats. CONCLUSIONS: QLP can effectively protect the reproductive system of oligoasthenospermia rats by raising sperm quality, elevating reproductive hormone levels, reducing oxidative stress injury, and improving histomorphology of the testis. 目的：研究麒麟丸对雷公藤多苷所致少弱精子症模型雄性大鼠的生殖功能保护作用。方法：取28只雄性SD大鼠，随机分成正常对照组、模型组、麒麟丸低、高剂量组，除正常对照组外，其他各组灌服雷公藤多苷40 mg/(kg·d)，同时麒麟丸给药组同日给予不同剂量麒麟丸保护，低剂量组给予麒麟丸1.62 g/(kg·d)，高剂量组给予麒麟丸3.24 g/(kg·d)。连续给药30 d后，处死大鼠，称重大鼠睾丸，计算睾丸脏器指数，检测附睾精子浓度、活动率，检测生殖激素水平，评估抗氧化指标，HE切片观察大鼠睾丸组织形态学改变。结果：实验结束后，麒麟丸低、高剂量组精子浓度分别为(14.57±3.95) ×10⁶/ml 、(39.71±11.31) ×10⁶/ml ，精子活力为(3.71±1.11)%、 (4.29±1.80)% 皆较模型组(4.71±1.25)×10⁶/ml、(0.57±0.53)%有明显提高（P<0.05）；与模型组FSH (1.71±0.52) mIU/ml比较，麒麟丸低、高剂量组FSH下降，分别为(1.49±0.62) mIU/ml 、(1.12±0.83) mIU/ml ；fT水平较模型组升高(27.27±3.63) nmol/L 、(32.80±2.51) nmol/L vs (22.81±2.75) nmol/L，SHBG水平升高(94.83±11.17) nmol/L 、(88.05±9.21) nmol/L vs (56.74±8.29) nmol/L，差异皆有显著性（P<0.05），但T水平无明显变化（P>0.05）。与模型组比较，麒麟丸低、高剂量组SOD水平升高(277.14±15.84) U/ml 、(299.60±20.83) U/ml vs (250.04±31.06) U/ml；ROS水平下降(397.61±62.71) IU/ml 、(376.84±67.14) IU/ml vs (552.20±58.07) IU/ml（P<0.05）。与模型组比较，低、高剂量组HE染色显示麒麟丸能增加少弱精子症大鼠睾丸生精小管内各级生精细胞层次和数量。结论：麒麟丸能明显提高少弱精子症大鼠精子质量，改善生殖激素水平，减轻氧化应激损伤，改善大鼠睾丸组织形态，对生殖系统有较好的保护作用。.
