血管内皮生长因子和第VIII因子相关抗原在脑出血大鼠脑内的表达
AIM:To observe the expression of vascular endothelial growth factor(VEGF) and Factor VIII related antigen(FVIII- R Ag) in rats brain tissue in the border zone of the hematoma,and explore the relationship between the expression of VEGF and the brain angionesis after intracerebral hmorrhage(ICH). METHODS:Rat of model of ICH was induced by injection of collagenase physiological saline into the right caudate nucleus.The immunohistochemical methods were performed by using different antisera of VEGF and FVIII- R Ag in serial sections of rats brain at 12 h,1 d,3 d and 7 d after ICH respectively.RESULTS:The amount of VEGF positive cells was markedly increased,and reached the highest at 7th day in the border zone after ICG(P< 0.01),but there were no significant difference among the mean value of A of cells at different time points (P >0.05).Compared with the controls,both the FVIII- R Ag positive endothelial cells and the A of cells were significantly different in experimental ICH goups after 1 day.CONCLUSION:The upregulated expression of VEGF might induce proliferation of endothelial cell and angiogenesis in the border zone after ICH in rats.
