摘要 目的:探讨脂肪性肝损伤过程中,肝组织NF-κB活性变化规律,及其与TNF-α的关系。方法:采用健康Wistar大鼠,随机分为正常对照组、实验组。实验组采用白酒灌胃加高脂饮食建立大鼠脂肪性肝炎模型。结果:实验组大鼠第8周出现严重的内毒素血症,NF-κB、TNF-α水平均明显高于对照组(P<0.01),且NF-κB与LPS、TNF-α、ALT、AST含量分别呈正相关(r值分别为0.914、0.947、0.634、0.612,P<0.01)。结论:脂肪性肝炎的发生与肝脏NF-κB活化紧密相关,故在脂肪性肝损害中可能起重要作用,抑制其过度活化对于防治脂肪性肝炎及阻止肝纤维化病理进程有重要意义。
