INTRODUCTION Some publications have demonstrated the presence of lung reperfusion injury in mesenteric ischemia and reperfusion (I/R), but under to diverse methods. Postconditioning has been recognized as effective in preventing reperfusion injury in various organs and tissues. However, its effectiveness has not been evaluated in the prevention of lung reperfusion injury after mesenteric ischem...

the anti-apoptotic gene bcl-2 is located in mitochondria, but it is uncertain whether its expression affects hepatocyte survival in ischemia/reperfusion (i/r) injury. this experiment was designed to evaluate the role of folic acid in expression of bcl-2 in i/r in rat liver. eighteen wister rats were divided into sham-operated controlgroup (c) (n=6), i/r group (n=6), folic acid treated group whi...

objective(s): to evaluate the protective effect of erdosteine, an antiapoptotic and antioxidant agent, on torsion–detorsion evoked histopathological changes in experimental ovarian ischemia-reperfusion (ir) injury. materials and methods: eighteen female wistar albino rats were used in control, ir, and ir+edosteine (ir-e) groups, (n=6 in each). the ir-e group received the erdosteine for seven da...

background renal ischemia reperfusion (ir) contributes to the development of acute renal failure (arf). oxygen free radicals are considered principal components involved in the pathophysiological tissue alterations observed during renal ir. objective in this study, we compared the effects of melatonin (mel) and erythropoietin (epo), which are known antioxidant and anti-inflammatory agents, in i...

anandamide is an endogenous ligand for cannabinoid receptors and has endothelial protective effect against ischemic preconditioning. the purpose of this study was to investigate the effects of cannabinoids on reperfusion injury due to testicular torsion-detorsion (t/d). a total of 36 adult male sprague-dawley rats were divided into 6 groups. testicular ischemia was achieved by twisting the righ...

objective(s): some histopathological alterations take place in the ischemic regions following brain ischemia. recent studies have demonstrated some neuroprotective roles of crocin in different models of experimental cerebral ischemia. here, we investigated the probable neuroprotective effects of crocin on the brain infarction and histopathological changes after transient model of focal cerebral...

objective(s):there are a few previously reported studies about the effect of nigella sativa oil on renal ischemia-reperfusion injury (iri). the aim of the present study was to test the hypothesis whether pre- or post-treatment with n. sativa hydroalcoholic extract (nse) would reduce tissue injury and oxidative damages in a clinically relevant rat model of renal iri.    materials and methods: ir...

introduction : intestinal ischemia and reperfusion (i-i/r) is an insult associated with acute respiratory distress syndrome (ards). herein we evaluate the dose-response effect of low-level laser therapy (lllt) on lung inflammation induced by i-i/r. methods : mice were subjected to mesenteric artery occlusion (45 min) and killed after clamp release and intestinal reperfusion (2h). increasing dos...
