摘要:

目的 探讨茶多酚在预防慢性酒精中毒对肝损伤方面的作用及其可能的机制。  方法 将40只雄性昆明小鼠随机分成正常对照组、酒精组、茶多酚低剂量组和茶多酚高剂量组。酒精组、茶多酚组连续90 d喂服30%酒精,8 h后再分别喂服纯水,浓度1%、2%的茶多酚悬液。正常对照组以同样方式和剂量每天2次喂服纯水。末次灌胃24 h检测血清中谷草转氨酶(AST)、谷丙转氨酶(ALT)的含量和肝组织中超氧化物歧化酶SOD、丙二醛(MDA)、组织内活性氧类物质(ROS)、谷胱甘肽过氧化物酶(GSH-px)的水平;同时,取肝组织行免疫组织化学显示Bcl-2和Bax的表达。  结果 与正常对照组比较,酒精损伤组肝细胞Bax阳性表达均明显升高(P<0.01),肝细胞Bcl-2阳性表达明显降低(P<0.01)。茶多酚喂服的两组有所改善。   结论 慢性酒精中毒可以引起肝损伤,而喂服茶多酚能减轻损伤程度。

Abstract:

Objective To investigate the preventive effect of tea polyphenols from liver injury in chronic alcoholism, and explore its possible molecular mechanisms. Methods 40 male kunming mice were divided into a control group, an alcohol group, a low dose group and a high dose group randomly. The mice model of alcoholic liver injury was duplicated by gavage and was given Alcohol and tea polyphenol respectively, using pure water as the control group. Then the mice′s AST, ALT, SOD, MDA, ROS, GSH-px,Bcl-2 and Bax of blood serum and liver tissue in each group weredetermined. Result The treatment medicine indicated that both the high or low doses of tea polyphenols could reduce the model of mice′s liver damage.     Conclusion The tea polyphenols could alleviate liver injury through inhibiting the preoxidation and eliminating free radicals.
