摘要: 目的 观察半枝莲治疗实验性肝纤维化大鼠对转化生长因子-β1(TGF-β1)和肿瘤坏死因子-α(TNF-α)表达的影响。方法 采用CCl4复合因素制作大鼠肝纤维化模型,通过免疫组化法和ELISA法分别检测TGF-β1、TNF-α在肝组织和血清中的含量;采用酶联免疫斑点技术(ELISPOT)检测单个细胞分泌TNF-α的含量。结果 正常对照组动物肝组织无TNF-α和TGF-β1表达,而模型组表达增强(P<0.05);高剂量半枝莲处理能降低两细胞因子的表达(P<0.05)。结论 半枝莲能抑制TGF-β1和TNF-α的分泌,因而有抗肝纤维化作用。

Abstract: Objective To observe the effect of barbata on transforming growth factor-β1 and tumor necrosis factor-α expression in rats with CCl4-induced liver fibrosis. Methods The model of CCl4 induced liver fibrosis in rats were established. The serum and liver tissue TGF-β1 and TNF-α were detected by immunohistochemistry and ELISA. Enzyme-linked immunosorbent dot technology(ELISPOT)was used to detect the single-cell secretion of TNF-α. Result TNF-α and TGF-β1 were negative in the normal control group and were obviously positive in model group;Barbata inhibited the expression of both TNF-αand TGF-β1in liver tissues and in sera. Conclusion Barbata has an antifibrotic effect by inhibition of cytokines in the liver.
