| 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。 |

| Objective: To investigate the effect of Naoyi’ an granule (NYAG) on basic fibroblastic growth factor (bFGF) mRNA expression and tumor necrosis factor (TNF) protein expression following intracerebral hemorrhage and provide the theoretical evidence of NYAG in treating intracerebral hemorrhage and promoting the rehabilitation of neural function. Methods: Model rats of intracerebral hemorrhage induced by infusion of collage-nase Ⅶ into the caudate-putamen were used to determine the related parameters of behavior scores (BS), Northern blot, Western blot assay and optical density (OD) scanning in the model and the model treated with NYAG. And the data got from the two groups were compared. Results: BS in the model group began to lower 24 hrs after modeling and a significant decrease was shown 7 days later, while in the NYAG group, it decreased significantly three days after modeling, the difference between the two groups was significant (P<0.05). Levels of bFGF mRNA expression and TNF protein expression increased after modeling, it reached the peak in three days and began to decrease gradually in seven days in both groups. However, the level in the NYAG group was higher than that in the model group in various times of the experimental process. Conclusion: NYAG could enhance the bFGF expression and suppress the TNF expression so as to improve the behavior deficit in treating intracerebral hemorrhage, which may be one of the main mechanisms of NYAG for promoting the rehabilitation of neural function. |
