Background: Renal ischemia reperfusion (RIR) injury is a common clinical syndrome that affects renal function and significantly increases morbidity and mortality. Hydrogen sulfide (H2S) is an endogenously gaseous mediator that exhibits many cytoprotective effects. Recently, studies have shown that H2S have opposite effects in different doses. Therefore, in the current study we investigated the ...
sIntroduction: Acute kidney injury (AKI) induced by ischemia-reperfusion (I / R) of the kidney as an inflammatory process in which multiple inflammatory factors are involved. Recently, one of the modalities of inflammation in AKI is Remote Ischemic Per-Conditioning (RIPerC). Materials and Methods: In this study, bilateral renal artery and vein occlusion were done for 45 minute and reperfusion a...
Background & Aim: Renal dysfunction due to ischemia-reperfusion (I/R) injury is a common problem following renovascular surgery or kidney transplantation. There is a lot of emerging evidence that statins, which are HMG-COA reductase inhibitors, have renal protective effects against ischemia-reperfusion injury,but the exact mechanism of their protective effect has not been detected properly....
Purpose: Ischemia-reperfusion (I/R) injury exacerbates myocardial cell death (including apoptosis and necrosis), leading to complications such as arrhythmias, stenosis, microvascular obstruction heart failure, it is particularly important seek new strategies mitigate reperfusion injury. In this paper, we will investigate whether atorvastatin can alleviate ischemia-reperfusion verify its molecul...
The purpose of this study is to evaluate the preventive effects Urtica dioica (UD) on muscle ischemia/reperfusion (I/R) injury. A total 27 male Wistar rats were divided into three groups as control group (1), I/R + saline (2), and I/R+UD (3). Group 1 did not receive any treatment. 2 was administered a 2mL/kg (1mL/kg before ischemia mL/kg after reperfusion), 3 given 2mL UD 1mL/kg reperfusion) Sa...
Purpose: Ischemia-Reperfusion (IR) injury is one of the most common cardiac disorders leading to irreversible heart damage. Many underlying mechanisms seem to be involved, among which disruption of cellular autophagy balance. Since physical training has a beneficial effect on the improvement of autophagy balance, it may have a cardioprotective effect against IR injury. This study investigates t...
The present study aimed to evaluate the protective effect of crocin on gastric mucosal lesions caused by ischemia-reperfusion (I/R) injury in rats.Forty male rats were randomly divided into sham, control (I/R injury) and three crocin-pretreated groups. To induce I/R lesions, the celiac artery was clamped for 30 min and then the clamp was removed to allow reperfusion for 3 h. Pretreated-rats rec...

A large amount of energy produced by active aerobic metabolism is necessary for the cochlea to maintain its function. This makes the cochlea vulnerable to blockade of cochlear blood flow and interruption of the oxygen supply. Although certain forms of human idiopathic sudden sensorineural hearing loss reportedly arise from ischemic injury, the pathological mechanism of cochlear ischemia-reperfu...
