Abstract:
Objective To study expression change of vascular endothelial growth factor(VEGF) protein and mRNA in rat brain with cerebral hemorrhage and effect of traditional Chinese medicine complex Nao Yi An(NYA) on VEGF expression. Methods The intracerebral hemorrhage(ICH) animal models were made by injecting collagenase type Ⅶstereotaxically into right globus pallidus. The experiment techniques of immunohistochemistry and in situ hybridization were employed to detect the expression variation of VEGF at 3h,6h,12h,1d,4d,7d and 14d after cerebral hemorrhage by positive cell counting as an observation index. Results The VEGF expression in the rat brains was observed at 3h after cerebral hemorrhage, raising at 6h,peaking at 12h and remaining peak until 1d. In the fourth day, VEGF began to decrease and still expressed a little at 7d and 14d.NYA could increase the VEGF expression in rat brains with cerebral hemorhage obviously at 6h ,12h,1d and 4d (P
