| Research Abstract |
We prepared arterial rings with 2. 5 mm length of human omental arteries without endothelium. Exposure toward a high concentration of D-glucose(22. 5 mmol/L) reduced both relaxation and hyperpolarization in response to an ATP-sensitive K+channel opener. In human vascular smooth muscle cells exposed to high glucose, intracellular levels of superoxide in addition to expression of NADPH oxidase subunit p47phox on cellular membrane increased and they were accompanied by the enhanced F-actin ratio in the smooth muscle cells
