摘要
目的研究壳寡糖(COS)对四氯化碳(CCl4)诱导的肝损伤的保护作用。方法雄性昆明种小鼠24只分为3组,正常对照组及CCl4模型对照组予以相应体积的生理盐水,COS组灌胃给予COS(1.5g/kg),后2组于第12天腹腔注射CCl4(20mg/kg)形成肝损伤模型。测定3组小鼠血清中丙氨酸转氨酶(ALT)和天冬氨酸转氨酶(AST)活性,以及肝匀浆中丙二醛(MDA)含量和DNA损伤情况。结果COS组与CCl4模型对照组相比,ALT,AST活性和MDA含量分别低62.2%,52.9%和34.3%。DNA电泳结果示,COS组与CCl4模型对照组的DNA链都形成一系列约1000bp的DNA片断。结论COS对CCl4诱导的肝损伤有较明显的保护作用,但是不能减轻DNA的氧化性损伤。
