摘 要:目的:研究硫辛酸(LA)对奥硝唑(ORN)所致少弱精子症模型雄性大鼠生精功能的保护作用。方法:取70只雄性SD大鼠,随机分成7组,每组10只,分别为:A组(溶剂对照组):1 ml 0.5%羧甲基纤维素钠(CMC-Na)+1 ml橄榄油;B组(低剂量ORN造模组):400 mg/kg ORN+1 ml橄榄油;C组(低剂量ORN+低剂量LA治疗组):400 mg/kg ORN+50 mg/kg LA;D组(低剂量ORN+高剂量LA治疗组):400 mg/kg ORN+100 mg/kg LA;E组(高剂量ORN造模组):800 mg/kg ORN+1 ml橄榄油;F组(高剂量ORN+低剂量LA治疗组):800 mg/kg ORN+50 mg/kg LA;G组(高剂量ORN+高剂量LA治疗组):800 mg/kg ORN+100 mg/kg LA。连续给药20 d,处死大鼠,称量大鼠体重、睾丸、附睾、精囊重量,计算脏器指数,检测附睾精子计数及活力,睾丸、附睾做HE染色观察组织形态学改变。结果:与A组相比,E组大鼠体重增量、睾丸、附睾脏器指数明显减少[(117.67±11.53)g vs(88.11±12.65)g;(1.06±0.12)%vs(0.65±0.13)%;(0.21±0.03)%vs(0.17±0.01)%,P均<0.01];与E组相比,F组大鼠附睾脏器指数明显增加[(0.17±0.01)%vs(0.20±0.02)%,P<0.01],G组大鼠体重增量、睾丸、附睾脏器指数明显增加[(88.11±12.65)g vs(102.70±16.10)g,P<0.05;(0.65±0.13)%vs(0.95±0.06)%,P<0.01;(0.17±0.01)%vs(0.19±0.02)%,P<0.05],精囊脏器指数各组之间并无明显差异。与A组相比,B组大鼠精子活力明显降低[(74.12±8.73)%vs(40.25±6.08)%,P<0.01],E组大鼠精子计数与活力明显降低[(38.59±6.40)×105/100 mg vs(18.67±4.59)×105/100 mg;(74.12±8.73)%vs(27.58±8.43)%,P均<0.01];与B组相比,C、D组大鼠精子活力明显增加[(40.25±6.08)%vs(58.13±7.62)%;(40.25±6.08)%vs(76.04±8.44)%,P均<0.01];与E组相比,F、G组大鼠精子计数及活力明显增加[(18.67±4.59)×10~5/100 mg vs(25.63±9.66)×10~5/100 mg,P<0.05;(18.67±4.59)×10~5/100 mg vs(29.92±4.15)×10~5/100 mg,P<0.01;(27.58±8.43)%vs(36.56±11.08)%,P<0.05;(27.58±8.43)%vs(45.05±9.59)%,P<0.01]。A、B、C、D组大鼠睾丸、附睾组织形态学无明显改变。E组大鼠睾丸Objective: To study the protective effect of lipoic acid (LA) on the spermatogenic function of the male rats with oligoasthenozoospermia induced by ornidazole (ORN). Methods: Seventy male SD rats were equally randomized into groups A (sol- vent control: 1 ml 0.5% CMC-Na ± 1 ml olive oil), B (low-dose ORN model: 400 mg/kg ORN suspension ± 1 ml olive oil), C (low-dose ORN ± low-dose LA treatment: 400 mg/kg ORN ± 50 mg/kg LA), D (low-dose ORN ± high-dose LA treatment: 400 mg/kg ORN ± 100 mg/kg LA), E (high-dose ORN model: 800 mg/kg ORN suspension ± 1 ml olive oil), F (high-dose ORN ± low-dose LA treatment: 800 mg/kg ORN ± 50 mg/kg LA), and G (high-dose ORN ± high-dose LA treatment: 800 mg/kg ORN ± 100 mg/kg LA), and treated respectively for 20 successive days. Then all the rats were sacrificed and the weights of the body, tes- tis, epididymis and seminal vesicle obtained, followed by calculation of the organ index, determination of epididymal sperm concentra- tion and motility, and observation of the histomorphological changes in the testis and epididymis by HE staining. Results : Compared with group A, group E showed significantly decreased body weight ( [ 117.67 ± 11.53 ] vs [ 88.11 ± 12.65 ] g, P 〈 0.01 ) and in- dexes of the testis ([1.06 ± 0.12] vs [0.65 ± 0.13] %, P 〈 0.01) and epididymis ([0.21 ± 0.03] vs [0.17 ± 0.01] %, P 〈 0.01 ). In comparison with group E, group F exhibited remarkable increases in the epididymal index ( [0.17 ± 0.01 ] vs [0.20 ± 0.02] %, P 〈 0.01), and so did group G in the body weight ([88.11 ± 12.65] vs [102.70 ± 16.10] g, P 〈 0.05) and the indexes of the testis ([0.65 ± 0.13] vs [0.95±0.06] %, P 〈 0.01) and epididymis ([0.17 ± 0.01] vs [0.19 ± 0.02] % , P 〈 0.05), but no obvious difference was observed in the index of seminal vesicle among different groups. Compared with group A, group B manifested significant decreases in sperm motility ( [74.12 ± 8.73] vs [
