摘要 目的探讨2型糖尿病与长期高脂对脂类代谢的影响程度,讨论高脂对肝细胞膜流动性的影响,以揭示2 型糖尿病中脂类代谢紊乱的机制。方法正常大鼠饲养、制造高脂10天大鼠模型、高脂20天大鼠模型、四氧嘧啶2型糖尿病大鼠模型,测定4组大鼠肝组织甘油三酯、总胆固醇含量、丙二醛(MDA)含量及肝细胞膜流动性。结果模型组与高脂10天组相比,肝组织MDA含量显著升高,肝细胞膜流动性显著降低,其甘油三酯及总胆固醇含量略低于高脂10天组及高脂20天组,但较正常组有一定程度的升高;高脂10天组与正常组相比,肝组织甘油三酯、总胆固醇的含量、MDA含量,均有显著升高,肝细胞膜流动性显著降低;高脂10天组与高脂20天组相比,肝组织甘油三酯的含量、MDA含量,以及肝细胞膜流动性变化均不显著,只有总胆固醇含量有显著下降。结论肝组织MDA含量、甘油三酯、总胆固醇含量及肝细胞膜流动性的变化与2型糖尿病的发病过程有密切关系,且肝组织MDA 含量对肝细胞膜流动性影响较大,与其变化情况密切相关。
