摘要
目的 :观察天年饮 (Tiannianyin ,TNY)对亚急性衰老大鼠睾丸组织超氧化物歧化酶(Superoxidedismutase ,SOD)的活性及对睾丸生精细胞凋亡的影响。方法 :采用D -半乳糖连续腹腔注射制作亚急性衰老大鼠模型 ,检测TNY灌胃前后大鼠血清睾酮含量、睾丸组织SOD的活性及睾丸生精细胞凋亡的情况。结果 :D -半乳糖致亚急性衰老大鼠血清睾酮含量及睾丸组织SOD的活性均明显下降 ,与正常大鼠比较差异显著 (P <0 0 5 ,P <0 0 1) ;经TNY灌胃后二者均升高接近正常水平 ,与模型大鼠相比有明显差异 (P <0 0 5 ,P <0 0 1)。D -半乳糖致亚急性衰老大鼠睾丸曲细精管凋亡百分率及凋亡细胞阳性率均升高 ,与正常组比较差异显著 (P <0 0 5 ) ;经TNY灌胃后 ,二者均降低 ,与模型大鼠比较有明显差异 (P <0 0 5 )。结论 :TNY可提高亚急性衰老大鼠血清睾酮含量、睾丸组织SOD的活性及降低衰老大鼠睾丸生精细胞的凋亡指数 ,具有一定延缓性腺衰老的作用。
