Effect of baicalin of the expression of NF-κB in acute liver failure in rats

  • 摘要: 目的观察急性肝衰竭大鼠肝脏NF-κB的表达水平及黄芩苷对其表达的影响。方法雄性SD大鼠106只随机分为正常组、肝衰竭组和黄芩苷组。肝衰竭组和黄芩苷组采用腹腔注射D-氨基半乳糖制备大鼠急性肝衰竭模型;黄芩苷组于造模后每隔12 h以120 mg/kg剂量腹腔注射。造模后24 h、72 h、120 h和168 h处死大鼠。全自动生化仪检测血清ALT、AST和TBil水平;HE染色观察肝脏病理学变化;RT-PCR法检测肝组织NF-κB、TNFα、Caspase-3 mRNA表达;免疫组化法检测肝组织NF-κB蛋白表达。结果黄芩苷组大鼠168 h存活率明显高于肝衰竭组。黄芩苷组大鼠各时间点血清ALT、AST、TBil水平较肝衰竭组明显降低(F=173.584,158.329,74.902;P<0.01)。黄芩苷组NF-κB、TNFα、Caspase-3 mRNA表达趋势与肝衰竭组相同,72 h达高峰,但表达量较肝衰竭组明显减少,差异有统计学意义(F=603.801,42.174,27.222,P<0.001,P<0.001,P=0.001)。黄芩苷组NF-κB蛋白的表达也于72...
