conclusions our study demonstrates that preconditioning of kidney with chronic ptu administration protects renal tissue against iri and this phenomenon was mediated through no system. the results suggest a potential indication for using ptu to protect the kidney before transplantations and to reduce the risk of tissue rejection afterwards. background renal ischemia/reperfusion injury (iri) is a...

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...

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...

conclusions treatment with epo and mel had a beneficial effect on renal ir injury. the results may also indicate that mel protects against morphological damage better than epo in renal ir injury. results ischemia-reperfusion significantly decreased the observed hb and hct values. the histopathological findings in the ir group confirmed that there was an increase in the hyaline cast and thickeni...

Introduction: Using brief episodes of ischemia and reperfusion (IR) prior to a more sustained IR insult – ischemic preconditioning (IPC) – can reduce IR injury of the heart, brain and many other tissues. The purpose of present study was to investigate the effect of 2min ischemic periods on subsequent rat renal IR injury. Methods: Male rat's renal IR injury was investigated in a right nephrectom...

conclusions pretreatment with epo and application of ipc significantly ameliorated the renal injury induced by bilateral renal ir. however, both treatments attenuated renal dysfunction and oxidative stress in kidney tissues. there were no significant differences between pretreatment with epo or application of ipc. materials and methods twenty four male wistar rats were allocated into four exper...

Introduction: Orexins are novel neuropeptides that are localized in neurons in the lateral hypothalamus. They are implicated in a wide variety of physiological functions. Orexin peptides and receptors are found in many peripheral organs such as kidneys. It has been demonstrated that exogenous orexin-A can induce protective effects against ischemia–reperfusion injury in many organs. The goal ...

Objective(s):Bradykinin is a part of the kinin-kallikreinsystem which is involved in ischemia-reperfusion injury via B1 and B2 receptors.Noscapine is a non-competitive antagonist of bradykinin receptors. Noscapine has been reported to to be able to protect some organs against ischemia-reperfusion injury but its effect on renal ischemia-reperfusion injury (RIR) in rats is unknown. Therefore, the...
