Abstract: 目的:研究鸡枞菌精多糖(refined polysaccharide from Termitomyces albuminosus,RTAP)对酒精所致急性肝损伤小鼠肾、脾脏及胸腺的保护作用.方法:采用超声波辅助的热水浸提法提取鸡枞菌多糖,小鼠被随机分为正常组、模型组、阳性对照组(饲喂联苯双酯,150 mg/(kg·d))、RTAP各剂量组(100、200、400 mg/ (kg·d)),连续灌胃30d,正常组按等量生理盐水灌胃.第31天除了正常组外,给予50%乙醇(12 mL/kg)建立动物急性肝损伤模型.小鼠处死后取肾脏、脾脏、胸腺,测定各项抗氧化指标.结果:与模型组相比,RTAP各剂量组均能降低肾脏、脾脏及胸腺丙二醛含量,提高各器官超氧化物歧化酶活性、过氧化氢酶活性、谷胱甘肽过氧化物酶活性及谷胱甘肽含量.结论:RTAP对酒精性损伤小鼠肾及免疫器官具有明显的抗氧化作用,其原理应该与其所具有抗脂质过氧化和清除体内过多的氧自由基作用有关.
