...- L -arginine)], after a single oral administration of telmisartan (80 mg) or placebo, using a randomized double-blind cross-over design. In six volunteers, we also assessed the roles of prostacyclin and EDHF (endothelium-derived hyperpolarizing factor) during radial FMD after AT 1 receptor blockade...

...Amrita AHLUWALIA Since the discovery of endothelium-derived hyperpolarizing factor (EDHF), several different candidates and pathways have been proposed as mediators of endothelium-dependent hyperpolarization of vascular smooth muscle. In particular, there has been considerable support for a role...

... -independent vasorelaxation in the human forearm. However, determining the contribution of this enzyme to regulation of blood flow in pathological conditions associated with endothelial dysfunction requires further studies. bradykinin cytochrome P450 endothelium-derived hyperpolarizing factor forearm...

... and endothelium-derived hyperpolarizing factor. When the former was abolished during nitric oxide synthase inhibition, an 80% diabetic deficit in the remaining relaxation was noted. LY333531 treatment attenuated the development of these defects by 64% and 53% respectively. Thus protein kinase Cβ contributes...

... not to do so in significant amounts. Thirty per cent of the relaxation induced by acetylcholine in human small arteries is mediated by release of endothelium-derived nitric oxide, whereas more than 60% is the result of release of another agent, perhaps the putative endothelium-derived hyperpolarizing factor...
