Expression of Vascular Endothelial Growth Factor in Heart and Serum after Myocardial Ischemia in Rats / 实用儿科临床杂志

Objective To study the change of vascular endothelial growth factor(VEGF) in myocardial tissue and serum of myocardial ischemia in rats.Methods Twenty SD rats were randomly divided into normal control group and test group. Test group was ligated coronary artery,and the control group was pulled on line but not ligated,then observed the change of VEGF.The histological and immunohistochemical method were used for observing the change of VEGF serum in myocardial ischemia in rats' heart.VEGF levels were measured by image analysis.Results Compared with control group,the expression of VEGF in the myocardial ischemia group was increased obviously(P
