Objective: Ischemia-reperfusion injury after acute ischemia treatment is a serious condition with high mortality and morbidity. Ischemia-reperfusion injury may result in organ failure particularly in kidney, lung, liver, and heart. In our study, we investigated the effects of papaverine and vitamin C on ischemia-reperfusion injury developed in the rat liver after occlusion-reperfusion of rat ao...

Serofendic acid is a low-molecular-weight compound extracted from fetal calf serum. We previously reported that intracerebroventricular administration of serofendic acid prevents cerebral ischemia-reperfusion injury. However, the effect of peripheral administration of serofendic acid on cerebral ischemia-reperfusion injury has not been examined. In the present study, we investigated the effect ...

Ischemia-reperfusion injury is a serious problem which can occur during lung transplantation. Preservation of pulmonary function by reducing ischemia-reperfusion injury is essential for successful lung transplantation. Although the mechanisms responsible for ischemia-reperfusion lung injury are not clear yet, it is commonly accepted that ischemic time, storage conditions and additive usage of s...

BACKGROUND It is well known that propofol protects myocardium against myocardial ischemia/reperfusion injury in the rat heart model. The aim of this study was to investigate whether propofol provides a protective effect against a regional myocardial ischemia/reperfusion injury in an in vivo rat heart model after 48 h of reperfusion. METHODS Rats were subjected to 25 min of left coronary arter...

Nitric oxide (NO) is involved in the pathogenesis of cerebral ischemic injury. Here, we investigated effects aging on NO production during ischemia-reperfusion (IR). Male Wister rats (WRs) were assigned to 12-month-old (older; n = 5) and 3-month-old (younger; 7) groups. Similarly, male spontaneous hypertensive (SHRs) allocated 6) 8) After anesthesia, their was monitored using vivo microdialysis...

Objective(s): Intestinal ischemia-reperfusion is a major problem, which may lead to multiorgan failure and death. The aim of this study was to evaluate the protective effects of dexmedetomidine on cell proliferation, antioxidant system, cell death, and structural integrity in intestinal injury induced by ischemia-reperfusion in rats. Materials and Methods: Animals were randomized into three gro...

Objective(s): Chronic diabetes impedes cardioprotection in reperfusion injury and hence protecting the diabetic heart would have important outcomes. In this study, we evaluated whether combined postconditioning with ischemia and cyclosporine-A can restore oxidative stress and histopathological changes in reperfusion injury of the diabetic myocardium. Materials and Methods: Streptozocin-induced ...

Objective- This study was performed to evaluate whether Trigonella foenum graecum (fenugreek) seeds extract has any protective activity in intestinal ischemia/reperfusion injury in rat. Design- Experimental study. Animals- 20 male Wistar albino rats. Procedures- Four groups of rats were included in this study. Group I (I/R) underwent ischemia-reperfusion (I/R) of the intestine (45 min of isc...

Polyamines (putrescine, spermidine, and spermine) are present in all higher eukaryotic cells and are essential for cell growth, differentiation and apoptosis. Sharing common precursor with polyamines, nitric oxide (NO) is associated with myocardial ischemia/reperfusion injury by the generation of peroxynitrite. Although polyamines have been implicated in tissue ischemia injury, their metabolism...

Acute renal failure resulting from hypoperfusion and hypoxia is a significant clinical problem. Hypoxia activates the heterodimeric transcription factor hypoxia inducible factor (HIF), leading to changes in gene expression that promote tissue adaptation and survival. To determine whether HIF may protect the kidney from ischemia-reperfusion injury, we subjected hif1a(+/-) and hif2a(+/-) mice to ...
