Figure 5From: Preserved endothelium-dependent dilatation of the coronary microvasculature at the early phase of diabetes mellitus despite the increased oxidative stress and depressed cardiac mechanical function ex vivoCoronary microvascular reactivity ex vivo. (A) Endothelial-dependent dilatation (EDD). (B) Endothelial-independent dilatation (EID). (C) Endothelial cell vasodilatation activity (ECVA). ZL: Zucker lean rats; ZDF: Zucker Diabetic Fatty rats; Ach: acetylcholine; SNP: sodium nitroprusside. The number of experiments was 11 and 10 for the ZL and ZDF groups respectively. *: significantly different.Back to article page
