introduction: this study was designed to evaluate the effects of treatment with flaxseed oil (fso) on renal ischemia-reperfusion (rir) injuries in rats. materials and methods: in this study, 32 wistar rats were randomly studied in four groups: co+ns (control group with normal saline administration), sh+ns (sham group with normal saline administration), rir+ns and rir+fso. fso (0.2 ml) was admin...
Introduction: Liver ischemia/reperfusion (IR) is a major clinical problem, which occurs during several conditions such as liver damage, trauma and transplantation. Recent studies indicate that IR-induced acute liver failure causes injuries of distant organs such as heart and lungs by systematic inflammatory responses. Therefore, in the present study, effects of hepatic IR induction were stud...
Objective: This study was conducted to evaluate the effect of a period of high-intensity interval training (HIIT) on myocardial collagen-1 and TGF-β1 and cardiac function in post ischemia-reperfusion rats. Materials and Methods: Thirty two (32) rats were anaesthetized by thiopental sodium. Intubation and connecting to ventilator and LAD ligation after thoracotomy was conducted. The ischem...
Organ damage after reperfusion of previously viable ischemic tissues is defined as ischemia/reperfusion injury. The pathophysiology of ischemia/reperfusion injury involves cellular effect of ischemia, reactive oxygen species and inflammatory cascade. Protection against ischemia/reperfusion injury may be achieved by preconditioning or postconditioning. In this review, we discuss basic mechanisms...
Background: Q10 coenzyme is a potent antioxidant in the mitochondrial membrane. Releasing the oxygen free radicals occurs in the cerebral ischemia. Using Q10 coenzyme causes strength against oxidative after injury of cerebral ischemia during reperfusion. Also CoQ10 plays an important anti-apoptotic role to reduce Caspase 3 as a key enzyme neuroprotective in apoptosis. According to the sensitive...
Many complicated mechanisms are involved in brain ischemia and the role of inflammatory factors in the progression of post-ischemic injury is inevitable. In present study, anti-inflammatory effect of berberine has been investigated in reperfusion injury after acute ischemic stroke. Male Wistar rats weighing 250-270 gr were randomly divided into four cohorts: healthy rats (control, n=20), sham-o...
conclusions the results suggest the important role of the antioxidant system potentiation in the prevention of myocardial damage. results cell degenerative changes, pyknotic nuclei, contraction bands, edema, and loosening of collagen in between muscle fibers were observed during ischemia-reperfusion. myocardial architecture and cellular morphology were recovered in co-administration groups, esp...
Epidemiological studies suggest that acute kidney injury has certain effect on myocardial function. In this study, for the first time, we tested a boron compound namely lithium tetraborate an act as anti-oxidant and anti-inflammatory agent in ischemia-reperfusion injury. For this, employed vivo rat model with ischemia reperfusion to evaluate cardiac clarify mechanisms of tetraborate. The evalua...
OBJECTIVE Ischemia reperfusion injury is partly responsible for the high mortality associated with induced myocardial injury and the reduction in the full benefit of myocardial reperfusion. Remote ischemic preconditioning, perconditioning, and postconditioning have all been shown to be cardioprotective. However, it is still unknown which one is the most beneficial. To examine this issue, we use...
Objective: Oxygen free radicals may be implicated in the pathogenesis of ischemia reperfusion damage. The beneficial effects of antioxidant nutrients, as well as complex plant extracts, on cerebral ischemia-reperfusion injuries are well known. This study was conducted to determine the effects of the hydro-alcoholic root extract of Withania coagulans on CA1 hippocampus oxidative damages followin...
