ABSTRACT
AIM:
To observe the expression of angiogenesis factors in the myocardial tissue of streptozotocin-induced diabetic rats .METHODS:
The diabetic rat model was induced by intraperitoneal injection of streptozotocin .After 12 weeks, the cardiac function was measured by MPA cardiac function analysis system .The myocardial collagen volume fraction ( CVF) was assessed by Masson staining .The capillary vessels was quantified as the ratio of capillary to myocyte (C/M) using CD31 immunostaining.The expression levels of vascular endothelial growth factor (VEGF), angiopoietin ( Ang)-1, endostatin and Ang-2 were observed by Western blotting .RESULTS:
Compared with normal control group , the left ventricular end-diastolic pressure (LVEDP) was evidently increased (P0.05).CONCLUSION:
Im-balances between the angiogenic factors (VEGF and Ang-1) and anti-angiogenic factors (endostatin) may play an impor-tant role in the pathogenesis of diabetic cardiomyopathy .
