【摘要】 输精管结扎12月以上日本大耳白兔16只,随机分为输精管结扎基础饲料(V-S)组和输精管结扎胆固醇(V-Ch)组。体重相近的同种雄兔16只,分为对照基础饲料(C-S)和对照胆固醇(C-Ch)组。听觉脑干电位检测结果表明:气导ABR阈值,输精管结扎组(V-S.V-Ch)与各门对照组比较无差异(P<0.05),而高胆固醇饲料组(C-Ch.V-Ch)则显著地高于对照组(P<0.01),并且与TC水平正相关(P<0.01);各组Ⅰ、Ⅲ、Ⅴ波潜伏期无延长,波间期各组比较也无显著差异,(P>0.05)。血清过氧化脂质含量与TC水平正相关(P<0.01)而与血清抗精子抗体滴度无相关(P>0.05)。本实验证明,实验性高血脂使气导ABR阈值及血清过氧化脂质增高,而输精管结扎对其无影响。更多还原

【Abstract】 Sixteen rabbits vaseetomized 12 months were divided into vasectomy stock diet(V-S) group and vasectomy cholesterol diet(V-Ch)group. 16 male rabbits of same body weight were divided into control stock diet(C-S) group and control cholesterol diet (C-Ch) group. The results showe that (1)the ABR threshold values of the vasectomy groups (V-S,V-Ch) were not different from those of the control groups(C-S,C-Ch), but the ABR threshold values of cholesterol diet groups(V-Ch,C-Ch) were markedly higher than those of stock diet groups (V-S,C-S) and were positively related to the TC level (P<0.01); (2) the Ⅰ, Ⅲ, Ⅴ latent periods and Ⅰ-Ⅲ, Ⅲ-Ⅴ intervals of brain stem response ahd no significant changes in all groups (P>0.05); (3) the serous lipid peroxide levels had apparently positive relation with the serous total cholesterol level (P<O.01), but no significant relation with antibody titres against sperm antigens (P>0.05).更多还原
