Tumor necrosis factor (TNF)-α plays a crucial role in the pathogenesis of ischemia/reperfusion-induced renal injury. We demonstrated recently that the preischemic treatment with resiniferatoxin, a transient receptor potential vanilloid 1 (TRPV1) agonist, attenuates renal TNF-α mRNA expression, and improves ischemia/reperfusion-induced renal injury in rats. In the present study, we investigated ...

Renal ischemia-reperfusion directly affects glomerular and tubular epithelium. Oxygen free radicals have a significant part in the pathophysiology of renal ischemia-reperfusion injury. The present study aimed to identify the effects of 3-week zinc, melatonin, and zinc + melato- nin supplementation on malondialdehyde (MDA) levels in tissue and plasma and glutathione levels (GSH) in erythrocytes ...

Lee, H. Thomas, and Charles W. Emala. Protective effects of renal ischemic preconditioning and adenosine pretreatment: role of A1 and A3 receptors. Am. J. Physiol. Renal Physiol. 278: F380–F387, 2000.—Renal ischemia and reperfusion during aortic and renal transplant surgery result in ischemic-reperfusion injury. Ischemic preconditioning and adenosine infusion before ischemia protect against isc...

Ischemia/reperfusion injury, which is commonly seen in the field of renal surgery or transplantation, is a major cause of acute renal failure. Previous studies showed that ozone oxidative preconditioning (OzoneOP) attenuated renal ischemia/reperfusion injury. The objective of this study was to examine the role of the OzoneOP in modulating inflammation and apoptosis after renal ischemia/reperfus...

ischemia reperfusion injury is the tissue damage caused when blood supply returns to the tissue after a period of ischemia or lack of oxygen. ischemia reperfusion induces cell death and endemic reaction that is one of the most important clinical problems with acute renal failure and renal transplantation. in this study, the effect of pentoxifylline on rat kidney function and cell injury followi...

Ischemia followed by reperfusion induces microvascular endothelial cell injury, leading to the loss of functions such as regulation of vascular tone, tissue perfusion, permeability, and inflammation in kidney. Improvement of this endothelial dysfunction could be a good approach to treating ischemia-reperfusion-induced renal injury. Cartilage oligomeric matrix protein-angiopoietin-1 (COMP-Ang1) ...

Signals that drive interstitial fibrogenesis after renal ischemia reperfusion injury remain undefined. Sympathetic activation manifests even in the early clinical stages of chronic kidney disease and is directly related to disease severity. A role for renal nerves in renal interstitial fibrogenesis in the setting of ischemia reperfusion injury has not been studied. In male 129S1/SvImJ mice, isc...

Background: The aim was to investigate the antioxidant effects of lycopene and caffeine in rats exposed renal ischemia/reperfusion injury. Materials Methods: Following right nephrectomy, 60 minutes ischemia followed by reperfusion were performed 200-250 gram Wistar albino used study. 30 before ischemia, (5 mg/kg), (50 mg/kg) + administered intraperitoneally rats. After experiment, 4 ml blood le...
