摘要
目的研究不同剂量镇肝熄风汤对自发性高血压大鼠(SHR)心血管组织Raf-1蛋白和Raf-1 mRNA表达的影响。方法将50只24周龄SHR随机分为模型对照组、中药小剂量组、中药中剂量组、中药大剂量组、阳性对照组,每组10只,同源雄性魏-凯二氏大鼠(WKY)10只作为正常对照组。灌胃给药5周后,Western Blot法测定心血管组织Raf-1蛋白表达,实时聚合酶链反应(RT-PCR)方法测定大鼠Raf-1 mRNA基因表达。结果与模型对照组比较,其他各组大鼠Raf-1蛋白和Raf-1 mRNA表达均明显升高(F=1 139.282,sig=0.000,P<0.01)。结论镇肝熄风汤可促进SHR心血管细胞Raf-1蛋白和Raf-1 mRNA表达,刺激细胞增殖和分化,抑制细胞凋亡。
Objective To study the effect of different doses of Zhengan xifeng decoction on Raf-1 mRNA and protein expression in the cardiovascular tissue of spontaneously hypertensive rats( SHR). Methods A total of 50 male SHR,24 weeks old,were randomly divided into the model,low dose,medium dose,high dose of Zhengan xifeng decoction and the compound apocynum groups,10 in each group. Ten homologous male rats( WKY) served as the normal control group. After gavaged for 5 weeks,western blotting and RT-PCR were used to detect the Raf-1 protein and mRNA expression in the cardiovascular tissue,respectively. Results Compared with the model control group,both Raf-1 protein and mRNA expressions significantly increased in all treatment groups( P〈 0. 01). Conclusion The Zhengan xifeng decoction can stimulate cell proliferation and inhibit cell apoptosis by up-regulating the expression of Raf-1.
