精安胶囊对大鼠精子质量的影响

目的 :探讨精安胶囊对大鼠精子质量的影响 ,为临床安全使用提供依据。　方法 :80只SD雄性大鼠 ,随机分为低剂量组 ( 5 5 7 1mg/kg) ,中剂量组 ( 5 5 71mg/kg) ,高剂量组 ( 114 2 0mg/kg)和阴性对照组 ( 2 0g/L淀粉 )共 4组 ,每组 2 0只 ,连续给药 6 0d后处死 ,取一侧附睾分析精子计数、活率和形态 ,实验数据运用方差、χ2 检验、Kruskal Wal lis检验进行统计学分析。　结果 :各剂量组精安胶囊对大鼠的精子密度、活率和形态有不同程度的影响。低剂量组精子密度显著增加 (P <0 .0 1) ,高剂量组精子密度和活率降低 ,且与阴性对照组比较差异有显著性 (P <0 .0 5 )。低剂量组精子形态异常率降低 ,中、高剂量组升高 ,但无统计学意义 (P >0 .0 5 )。　结论 :低剂量精安胶囊可改善精子质量 ,高剂量精安胶囊可能对精子产生一定的损伤

Effects of Jing'an Capsule on Rat Sperm Quality

OBJECTIVE: The effects of Jing'an capsule on the quality of rat sperm were studied to supply data for its safe clinical use. METHODS: Eighty SD male rats were evenly and randomly divided into three test groups and one control group. Then the test groups were continuously given Jing'an capsule at different dosages: 557.1 mg/kg, 5,571 mg/kg or 11,420 mg/kg and the control group was given starch (20 g/L). Sixty days later, one of the epididymides, the sperm density was made and the sperm motility and morphology were investigated. The data obtained were analyzed by ANOVA, chi 2 test and Kruskal-Wallis test. RESULTS: The sperm density, motility and morphology were variable at different dosages. Compared with the control, the sperm density increased significantly at the dosage of 557.1 mg/kg(P < 0.05), and a significant decrease was observed in the sperm density and motility (P < 0.05) at the dosage of 11,420 mg/kg. Although the rate of abnormal sperm morphology decreased at the dosage of 557.1 mg/kg and increased at the dosage of 5,571 mg/kg or 11,420 mg/kg compared with the control, there was no statistic significance(P < 0.05). CONCLUSIONS: A low dosage of Jing'an capsule might ameliorate the quality of sperm, while a high dosage could do damage to sperm.
