摘要

目的　探讨茶多酚预防慢性酒精中毒对精子损伤的作用及其可能机制。方法　40只雄性小鼠随机分为4组：酒精损伤组（CA组）、茶多酚低剂量组（TP-L组）及茶多酚高剂量组（TP-H组）每天先喂服酒精，8 h后再分别喂服纯水、或浓度为1%或2%的茶多酚悬液。正常对照组（NC组）以同样方式和剂量每天2次喂服纯水。90 d后取材制备精子悬液用于精子密度、精子活动率及畸形率的检测。同时，取睾丸组织行免疫组织化学检测Bcl-2和Bax的表达。结果　与NC组比较, CA组的精子密度和精子活动率明显下降，精子畸形率明显增加。相对于CA组,TP-L组及TP-H组精子密度和精子活动率增高, 精子畸形率降低，其中TP-H组的效果比TP-L组更显著。CA组睾丸组织中Bcl-2的阳性细胞比NC组显著减少，Bax的阳性率却明显升高。喂服茶多酚却能明显逆转由酒精导致的上述变化。结论　茶多酚能预防酒精对精子的损伤,这可能与精子发生过程Bcl-2及Bax的表达变化有关。

Abstract

Objective　To explore the preventive role of tea polyphenol (TP) on the chronic alcoholism induced sperm damage and the potential mechanisms.　Methods　Forty male Kunming mice were randomly divided into chronic alcoholism (CA) group, TP low-dosage (TP-L) group, TP high-dosage (TP-H) group and normal control (NC) group. Eight hours after daily alcohol administration, the mice in CA, TP-L and TP-H groups were treated with water, 1% TP or 2% TP respectively. The mice in NC group were administered with water twice a day. 90 days later, sperm suspension was prepared to detect sperm density, activity ratio and malformation ratio; Bcl-2 and Bax expression were observed in testicular tissue via immunohistochemistry.　Results　In CA group, the density, activity ratio of sperm and ratio of Bcl-2 positive cells in testicular tissue were lower, the ratios of sperm malformation and Bax positive cells in testicular tissue were higher than that of NC group. Above changes were reversed in the TP-L and TP-H groups. Moreover, this benign effect showed a positive correlation with dosage.　Conclusion　Tea ployphenol could alleviate alcoholism induced sperm damage. This effect might relate with the Bcl-2 and Bax expression during spermatogenesis.
