Objective To investigate the role of oxidative stress in impaired intermediate-conductance Ca 2 + -activated potassium channels (IK Ca )- and small- conductance Ca 2 + - activated potassium channels (SK Ca )- mediated relaxation in diabetic resistance arteries. Methods Rat diabetic model was induced by a high fat and high glucose diet and streptozotocin (STZ) injection. Endothelial function of mesenteric arteries was assessed with the use of wire myography. The expression levels of IK Ca and SK Ca in cultur...
