| Research Abstract |
DM significantly decreased the coronary vasodilatation compared with Control in both coronary small arteries and arteries, whereas DM+ARB (angiotensin receptor inhibitor, olmesartan) +L-NMMA (DAL) DAL significantly improved the vasodilatation compared with DM in coronary small arteries and was significantly decreased by DAL+Apamin+Charybdotoxin (DALAC,both KCa channel blocker) in coronary arterioles. DAL ameliorated myocardial injury and oxidative stress compared with DM, as assessed by 8-OHdG, myocardial troponin-I and apoptosis, respectively.
