ABSTRACT
AIM:
We observed the expression of KDR/Flk1 in post-myocardiac ischemia(MI) SD rats in order to explain the effect of captopril and its relationship with myocardium angiogenesis after long-term administration.METHODS:
The MI model was made by LAD ligation.Captopril was administered for 6 weeks.Immuohistological method and FQ-PCR were used to test the myocardium KDR/Flk-1 expression.RESULTS:
In captopril group,no inhibitory effect was observed in myocardium factor VIII expression,but KDR/Flk-1 decreased.The copies of KDR/Flk-1 mRNA reduced dramatically when compared to control group,false-operation and normal group(P0.05).CONCLUSION:
ACEI down-regulates KDR/Flk-1 and its mRNA expression in ischemic rat myocardium after long-term administration of captopril,but does not inhibit angiogenesis.So we suspect that some other pathways exist,which can not affect by ACEI,or that ACEI just reduces abnormal angiogenesis.
