摘要
目的:探讨脑溢安颗粒(简称脑溢安)对脑出血大鼠脑内碱性成纤维生长因子(bFGF)mRNA和肿瘤坏死因子(TNF)蛋白表达的影响。方法:用Ⅶ型胶原酶诱导大鼠脑出血模型,进行行为学计分、Northern blot、Western blot及吸光度扫描测定相关指标。结果:模型组的行为学计分在术后24h开始降低,7d时明显降低(P<0.05),脑溢安组3d即有明显的降低(P<0.05);模型组、脑溢安组bFGF mRNA和TNF蛋白表达在3d时达到高峰,7d时逐渐减弱,而脑溢安组在各个时间点的表达均强于模型组。结论:脑溢安治疗脑出血能增强bFGF的表达,抑制TNF蛋白表达,从而使行为学得到改善,这可能是脑溢安促进神经功能修复的主要机制之一。
