Modulation of Renal Blood Flow and Vascular Tone by Neuronal Nitric Oxide Synthase-Derived Nitric Oxide
Nitric oxide (NO) formed via neuronal nitric oxide synthase (nNOS) in renal vasculature and tissues and in the brain plays an important role in controlling renal hemodynamics, renal function, and systemic blood pressure. Activation of parasympathetic nitrergic nerves innervating renal vasculature contributes to vasodilatation in renal arteries and preand postglomerular arterioles, an increase i...

متن کاملElevated skeletal muscle blood flow in noncomplicated type 1 diabetes mellitus: role of nitric oxide and sympathetic tone.
Capillary hyperperfusion precedes and contributes to the occurrence of diabetic microangiopathy. Vascular tone is regulated by the balance of vasodilating and vasoconstricting factors, of which nitric oxide (NO; an endothelium dependent vasodilator) and norepinephrine (NE; a potent vasoconstrictor), respectively, are of primary importance. To investigate the role of these factors in hyperperfus...
متن کاملSympathetic activation and nitric oxide function in early hypertension.
The purpose of this study was to determine if tonic restrain of blood pressure by nitric oxide (NO) is impaired early in the development of hypertension. Impaired NO function is thought to contribute to hypertension, but it is not clear if this is explained by direct effects of NO on vascular tone or indirect modulation of sympathetic activity. We determined the blood pressure effect of NO synt...
متن کاملNitric oxide and the bioactivities
Nitric oxide (NO), previously known as Endothelium-Derived Relaxing Factor (EDRF) is involved in a wide range of physiological and pathophysiological mechanisms. It is synthesized endogenously by the enzymes Nitric Oxide Synthase (NOS) in specialized tissues from its precursor L-arginine, yielding L-citrulline as a byproduct. It is released by a family of isoenzymes, viz., the endothelial (eNOS...
