| Research Abstract |
We evaluated the endothelial dependent nitric oxide production in a canine model of metabolic syndrome induced by high fat diets and we demonstrated that the endothelium-dependent nitric oxide production was diminished according to the deterioration of insulin resistance. However, drug induced maximal hyperemia of coronary microcirculation was maintained in a same model, so it was possible that in case of the elimination of nitric oxide bioavailability, coronary vasodilatation was maintained by other vasoactive factors, such as adenosine or prostaglandin. We also evaluated the optimal value of the cuff pressure and the ischemic time at measurement of the flow mediated vasodilatation response of human forearm and demonstrated that resting blood pressure plus 30 mmHg and 5 minutes were optimal.
