Diazoxide produced concentration-dependent relaxation of calf cardiac vein and coronary artery rings pre-contracted with carbachol (10(-6) m). During cooling, the pIC(50) values, but not the maximal responses, to diazoxide were significantly lower than at 37 degrees C in both preparations. Cooling to 28 degrees C in the presence of N(G)-nitro-L-arginine methyl ester (10(-4) m) did not modify the effect of temperature both in cardiac vein and coronary artery. These results suggest that cooling-induced changes of diazoxide in calf cardiac vein and coronary artery are independent of nitric oxide.en10.1111/j.1472-8206.2009.00671.xinfo:eu-repo/semantics/closedAccesscardiac veincoolingcoronary arterydiazoxidenitric oxideArticle23327127719469805Q2WOS:000266598700002Q2
