黄芩苷对肝脏缺血再灌注损伤大鼠诱生型一氧化氮合酶、核转录因子和Caspase-3表达的影响
Effects of Baicalin on iNOS, NF-κB and Caspase-3 in Liver Ischemia Reperfusion Injury Rats
摘要
Abstract
Objective To observe the effects of baicalin on forms of hepatic tissue, liver apoptosis, mRNA expressions of iNOS, NF-κB and protein expression of Caspase-3 in rats with ischemia reperfusion injury; To discuss its mechanism of action.Methods The rat models of liver ischemia reperfusion were performed according to the Pringle's method. Rats were randomly divided into sham-operation group, model group and baicalin group. Sham-operation group and model group were given normal saline for gavage, while baicalin group was given baicalin for gavage. Morphological characteristic was observed by HE staining. Hepatocyte apoptosis was determined by TUNEL. The mRNA expressions of iNOS and NF-κB were determined by RT-PCR. The protein expression of Caspase-3 was determined by Western blot.Results Compared with the sham-operation group, mRNA expressions of iNOS and NF-κB and the protein expression of Caspase-3 in the model group increased, as well as liver apoptosis rate (P<0.05,P<0.01); compared with the model group, mRNA expressions of iNOS and NF-κB and the protein expression of Caspase-3 in the baicalin group decreased, as well as liver apoptosis rate (P<0.05), and the hepatic lesion significantly improved in the baicalin group.Conclusion Baicalin can restrain Caspase-3 induced apoptosis by reducing the expressions of iNOS and NF-κB, with a purpose to realize the hepatoprotective effect for liver of rats with ischemia reperfusion injury.关键词
