摘要 目的:探讨有氧运动和补充大豆多肽对非酒精性脂肪肝大鼠肝脏的保护作用及其可能机制。方法:雄性SD大鼠60只,随机分为对照组(C组)、高脂组(HF组)、高脂饮食+运动组(HE组)、高脂饮食+大豆多肽组(HS组)、高脂饮食+运动+大豆多肽组(HES组)5组。运动方案是10周60min的无负重游泳运动,每周6天。SPI灌胃剂量为500mg/kgBW。10周后,检测大鼠血清AST、ALT、LDH活性,肝组织SOD活力和MDAIL-6的含量。结果:与C组相比,HF组大鼠血清ALT水平有上升的趋势,但不明显(p>0.05);但是HF组大鼠血清AST和LDH活性显著升高。通过双因素方差分析,有氧运动或补充大豆多肽可以显著地降低高脂饮食大鼠血清AST、ALT和LDH的活性,而且有氧运动和补充大豆多肽对于降低高脂饮食大鼠血清AST和LDH活性均具有显著的交互作用,从而使它们的活性进一步降低。与C组相比,HF组大鼠肝组织中SOD活力显著下降(p<0.01),MDA含量显著上升(p<0.01),从而导致SOD/MDA显著降低(p<0.01)。双因素方差分析显示,有氧运动锻炼或补充大豆多肽均能使高脂饮食大鼠肝组织中SOD活性显著升高(p<0.01),MDA含量显著降低(p<0.05),从而使SOD/MDA显著升高(p<0.01);运动训练联合补充大豆多肽可使高脂饮食大鼠肝组织中SOD活性升高,MDA含量进一步降低,且具有显著的交互作用。运动锻炼联合补充大豆多肽虽然能使SOD/MDA进一步升高,但无显著性差异。结论:脂肪肝大鼠肝组织氧自由基的生成增多,可能也是导致肝细胞损伤和引起血清酶活性增高的机制。有氧运动和大豆多肽可以加快高脂饮食大鼠肝组织中氧自由基的清除,预防肝细胞的损伤。 In order to probe the protective function and its potential mechanism of the aerobic exercise and soy bean multipeptide to the liver of the rats with un-aleohol fatty liver disease, through comparative experiments, this article gets the result that during the experiment the free radical increased so much in the liver cells of the fatty liver rats that maybe led the liver cells' injury and serum enzyme raising; the aerobic exercise and soy bean multi-peptide could speed up the eliminating of the free radicals in liver, and protect the liver cells from being damaged.
