摘要: 目的 探讨转化生长因子(TGF-β1)在大鼠心肌缺血坏死模型中的作用及阿魏酸钠(SF)的干预效应。方法 注射盐酸异丙肾上腺素(Iso,15mg/kg)复制大鼠心肌缺血性坏死模型。稳定2d后注射SF(110mg/kg)进行干预。用免疫组化及RT-PCR法测定心肌组织中TGF-β1蛋白及mRNA表达。结果 注射Iso后 24 h,TGF-β1 mRNA表达较对照组明显增加(P <0.05);自48 h后mRNA表达逐渐下降,TGF-β1蛋白的表达随病变加重而增加。SF干预后TGF-β1mRNA表达显著减轻,其蛋白表达亦有改善。结论SF可抑制TGF-β1在大鼠缺血坏死模型心肌中的表达。

Abstract: Objective To investigate the TGF-β1 expression and the effects of sodium ferulate in rats' myocardium necrosis model. Methods Rat myocardium necrosis model was induced by Isoproterenol (15mg/kg). The rats were injected SF to carry out intervention studies after stable 2 days. TGF-β1 protein and mRNA expression in myocardium were detected by immunohistochemistry and RT-PCR. Results TGF-β1 mRNA expression increased obviously as compared with control group at 24 h(P <0.05)and decreased gradually at 48 h. TGF-β1 protein expression increased to follow the severity. TGF-β1 mRNA expression decreased gradually by injection SF later, its protein expression was also improving. Conclusion SF could inhibit TGF-β1 expression in MF.
