Chapter 1 Endothelium-Dependent Hyperpolarizations: The Classical “EDHF” Pathway A lot of confusion has arisen in the field of endothelium-dependent hyperpolarizations due to the use of the acronym “EDHF” which implies that a single diffusible substance underlies this novel mechanism of relaxation of the vascular by: 1.

The first two meetings established a role for EDHF and other chemical factors involved in endothelium-dependent hyperpolarizations. These proceedings focus upon the role of gap junctions in cardiovascular responses and investigate the chemical identity of : Hardcover.

Book Description. Understanding the nature and role of endothelium-derived hyperpolarizing factor appears to be crucial in the quest for improved treatments for hypertension, diabetes, ischemia-reperfusion and other vascular disorders. EDHF comprises the proceedings of the Third International Symposium on endothelium-dependent hyperpolarizations.

EDHF contains the proceedings of the Fourth International Symposium on endothelium-dependent hyperpolarizations and will be of interest not only to physiologists and pharmacologists puzzled by the complexity of the interactions between the endothelium and underlying vascular smooth muscle cells, but also clinical researchers and physicians.

EDHF comprises the proceedings of the Third International Symposium on endothelium-dependent hyperpolarizations. The first two meetings established a role for EDHF and other chemical factors involved in endothelium-dependent hyperpolarizations.

Like the release of nitric oxide, endothelium-dependent hyperpolarization apparently depends on calcium calmodulin, because inhibitors of this enzyme, calmidazolium and fendiline, decrease the endothelium-dependent hyperpolarization and relaxations of the porcine coronary artery to bradykinin, which are resistant to inhibitors of nitric oxide.

Endothelium-dependent relaxations can be mediated by the release of the endothelium-derived nitric oxide and prostacyclin []. In addition, endothelial cells release a yet unidentified endothelium-derived hyperpolarizing factor (EDHF), which causes membrane hyperpolarization by opening potassium channels in vascular smooth muscle [ 3 - 4 ].Cited by: 1.

We examined endothelium-dependent and -independent hyperpolarizations and endothelium-dependent relaxation responses in carotid arteries isolated from streptozotocin-induced diabetic rats and age-matched controls.
