摘要: 目的 探讨富硒灵芝多糖对非酒精性脂肪肝病大鼠SREBP-1c及ACCα表达的影响。方法 120只SD大鼠随机分为正常组、高脂饮食组、多烯磷脂酰胆碱组、富硒灵芝多糖低、中和高剂量干预组等6组,每组20只,分别于治疗4和8周后处死大鼠各半,测血清中谷草转氨酶(AST)、谷丙转氨酶(ALT)、总胆固醇(CHOL)和三酰甘油(TG);用Western blot和RT-PCR检测肝脏组织中SREBP-1c及ACCα蛋白和mRNA表达;其余肝脏行病理学检测。结果 富硒灵芝多糖可显著减少肝脏组织中的脂肪颗粒,并降低血清中AST、ALT、CHOL和TG含量,中、高剂量的灵芝多糖处理可显著降低肝脏中SREBP-1c、ACCα mRNA和蛋白的表达(p<0.05)。结论 富硒灵芝多糖可缓解高脂饮食诱导的非酒精性脂肪肝大鼠症状。

Abstract: Objective To investigate the expression of ACCα and SREBP-1c of selenium-enriched Ganoderma lucidum polysaccharides on fatty liver rats model. Methods 120 SD rats were randomly divided into control, high-fat diet, polyene phosphatidylcholine, Se G. lucidum polysaccharides low, medium and high group, after 4 and 8 weeks of treatment the rats were sacrificed, measuring the AST, ALT, CHOL and TG in blood serum, detect SREBP-1c, ACCα mRNA and protein expression by Western Blot and PCR respectively. Results With the increase of treatment dose and treatment time of Se G. lucidum polysaccharides, fatty infiltration of the liver was significantly reduced, fat particles significantly reduced; liver function and blood lipids significantly improved; SREBP-1c, ACCα mRNA and protein expression was significantly decreased. Conclusion Se G. lucidum polysaccharides can relieve the symptoms of non- alcoholic fatty liver disease in rats.
