Research Abstract

1. We assessed methods of the measurement of endothelial function by flow-mediated vasodilatation and of aortic stiffness by pulse wave velocity. We also standardized the method of flow-mediated vasodilatation, which had varied among researchers.
2. We estimated the association of insulin sensitivity measured by glucose clamp technique and serum metabolic marker such as adiponectin.
3. The methods of experiments in humans for the assessment of effects of elevated free fatty acids on angiotensin II forming activity in leukocytes, endothelial function, insulin sensitivity, and leukocyte activation was established. We tested effects of several cardiovascular drugs in this lipid loading experiment mimicking visceral fat obesity. We found that elevated FFA caused endothelial dysfunction, microcirculatory dysfunction (leukocyte activation), insulin resistance partly via leukocyte renin-angiotensin system. This experimental protocol may be useful for the assessment of anti-atherosclerotic drugs. Leukocyte angiotensin II forming activity could be a biomarker for visceral fat obesity linking to vascular dysfunction.
