摘要: 背景与目的: 研究枸杞多糖对应激大鼠生殖功能的保护作用,并探讨其保护机制。 材料与方法: 实验大鼠依体重和旷场实验评分随机分为6组:对照组,应激组,枸杞多糖高(20 mg/kg)、低剂量组(10 mg/kg)及枸杞多糖高剂量+应激组和低剂量+应激组。采用束缚制动+噪音的方法建立应激动物模型,用枸杞多糖进行干预,观察生殖功能相关指标的变化和睾丸组织形态的改变。 结果: 应激组大鼠体重的增重较对照组降低,精子数量减少,精子活率降低,畸形率升高,血清睾酮含量降低(P均<0.01)。与应激组相比,枸杞多糖可使应激大鼠体重升高,精子数量增多,精子活率升高,畸形率降低,血清睾酮含量上升(P<0.05或P<0.01),能降低慢性心理应激引起的生精细胞损伤,促进睾丸生殖细胞正常发育。 结论: 枸杞多糖对慢性心理应激大鼠的生殖系统具有一定的保护作用。

Abstract: BACKGROUND AND AIM:To investigate the effects of lycium barvarum polysaccharides(LBP) on the reproductive system in male rats under chronic psychologic stress. MATERIALS AND METHODS: Rats were randomly divided into 6 groups:control group, stress group,high dose LBP group(hLBP),low dose LBP group(lLBP) , hLBP+stress group and lLBP+stress group.Sexual homone levels and sexual organ indexes were measured after four weeks. RESULTS: The sperm count and activity were increased significantly, and abnormality percentage was reduced in stress group. LBP protected the spermatogenic cells and promoted the normal development of testicular germ cells. CONCLUSION: LBP could enhance the reproductive function of chronic mentally stressed rats. The mechanism might be through adjustment of hypothalamus_pituitary_gonadal axis and target receptors.
