The role of nitric oxide in renal transplantation.

The role of nitric oxide in the protective action of remote ischemic per-conditioning against ischemia/reperfusion-induced acute renal failure in rat

Objective(s): We investigated the role of nitric oxide (NO) in the protective effects of remote ischemic per-conditioning (rIPerC) on renal ischemia/reperfusion (I/R) injury in male rats. Materials and Methods: I/R treatment consisted of 45 min bilateral renal artery ischemia and 24 hr reperfusion interval. rIPerC was performed using four cycles of 2 min occlusions of the left femoral artery an...

Effects of lipopolysaccharide-induced septic shock on rat isolated kidney, possible role of nitric oxide and protein kinase C pathways

Objective(s): Pathophysiology of sepsis-associated renal failure (one of the most common cause of death in intensive care units) had not been fully determined. The effect of nitric oxide and protein kinase C (PKC) pathways in isolated kidney of Lipopolysaccharide-treated (LPS) rats were investigated in this study. Materials and Methods: Vascular responsiveness to phenylephrine and acetylcholine...

Nephrotoxicity of Isosorbide Dinitrate and Cholestasis in Rat: The Possible Role of Nitric Oxide

Background: Nitric oxide (NO), a major chemical form of endothelium-derived relaxing factor and an important regulator of vascular tone, is released by endothelial cells. The role of NO is not restricted to the vascular system, and it participates in the regulation of renal hemodynamics and renal excretory function. There are increasing evidences indicating that the elevated levels of NO play a...

Does Nitric Oxide Generated by Dendritic Cells Contribute to the Low Incidence of GVHD after Cord Blood Transplantation?

Role of nitric oxide and superoxide balance in hypoxia-reoxygenation proximal tubular injury.

Under normal physiological conditions activation of nitric oxide synthases produces both nitric oxide and superoxide in equimolar concentrations (Figure 1). We propose a hypothesis that in hypoxia-reoxygenation injury this balanced co-production of nitric oxide and superoxide is disturbed and results in pathological effects. Specifically, under hypoxic conditions nitric oxide synthase is activa...
