renal ischemia-reperfusion (ir) contributes to the development of acute renal failure (arf). oxygen free radicals are considered to be principal components involved in the pathophysiological tissue alterations observed during renal ir. the purpose of this study was to investigate the combination effect of melatonin (mel) and erythropoietin (epo), which are a potent antioxidant and anti-apoptoti...

objective(s) the aim of this study was to investigate the overall effect of cardiac vasoactive factors during coronary occlusion and reperfusion on peripheral vascular tone, using a sequential isolated rabbit heart-ear perfusion model. materials and methods isolated ears were perfused with the effluent of isolated hearts subjected to ischemia (30 min) and reperfusion (180 min, n=6). the compara...

Abstract: Background: Neuroprotection is one of considerable interest in search novel therapies to improve ischemic brain damage the present scenario. The objective investigation study actions Talinum triangulare cerebral ischemia/reperfusion induced oxidative stress Wistar rats and in-vitro antioxidant actions. Methods: Four different groups adult are selected for where group III IV treated 15...

Aim: to study the effect of reperfusion on organized frequency-amplitude structure ventricular fibrillation (VF) in dog heart. Materials and methods. We conducted 4 experiments 8 dogs. In each experiment, isolated heart one was perfused with blood second (supporting) dog. an artificially heart, 6 episodes 3-minute ischemia 10-minute were performed VF (1-2 ischemia-reperfusion experiment). Each ...

Introduction: This study investigated the effect of berberine on renal dysfunction and histological damages of the lung induced by renal ischemia/ reperfusion at an early stage. Methods: There were four experimental groups of adult male rats (n=7). Seven days before induction of ischemia, the Ber+I/R group received oral (by gavage) berberine (15 mg/kg/day) while the I/R group received distil...

background: the role of nitric oxide (no) of endothelial or neuronal origins in cerebral ischemia and reperfusion injuries are far from being settled, extending from being important to not having any role at all.    objective: to investigate the role of no of endothelial and neuronal origins in ischemia/reperfusion injuries in focal cerebral ischemia, l-name, a non selective no synthase inhibit...

Interleukin-1 (IL-1) is a highly potent molecule that has a myriad of effects in biologic systems. This brief review describes some of our findings on the effects of IL-1 in biologic systems. On the one hand, IL-1 treatment caused a neutrophil-dependent acute edematous lung injury that resembled changes in the lungs of patients with the acute respiratory distress syndrome (ARDS). On the other h...
