Objective: Ischemia-reperfusion (I-R) injury is defined as the paradoxical exacerbation of cellular dysfunction and death following restoration blood flow to ischemic tissues. In our study, it was aimed examine potential DNA effects liver IR with an experimental animal model. Material Methods: modeling done seven male New Zealand rabbits. Blood samples were taken before model, 30 minutes after ...

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...

objective: several studies have shown that chichorium intybus l. (c. intybus) which possesses flavonoid compounds has an effective role in treatment of cardiovascular diseases. contractile dysfunction mostly occurs after acute myocardial infarction, cardiac bypass surgery, heart transplantation and coronary angioplasty. the aim of the present study was to investigate the effect of aqueous extra...

Abstract Introduction: Resent studies have been shown beneficial effects of hyperoxia pretreatment against ischemia-reperfusion injury in different organs. The aim of the present study was to investigate early and late effects of normobaric hyperoxia (≥95% O2) pretreatment on ischemia-reperfusion injuries in isolated rat hearts. Methods: Following 60 and 180 minutes of hyperoxia, rat hearts w...

Objectives: Ischemia/reperfusion (I/R) injury is commonly seen in cardiovascular surgery, activates inflammation and causes renal damage. In this experimental study, we aimed to assess the effects of different doses (5 30 mg/kg) methylprednisolone (MP), which has anti-inflammatory effect, on ischemia/reperfusion injury. Methods: Thirty-two male Wistar albino rats were randomly divided into four...

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...

Acute myocardial infarction (AMI) is the leading cause of death, morbidity, and health costs worldwide. In AMI, a sudden blockage blood flow causes ischemia cell death. Reperfusion after has paradoxical effects may exacerbate injury, process known as ischemic reperfusion injury. this work we evaluated lipidome isolated rat hearts, maintained in controlled perfusion (CT), undergoing global (ISC)...

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...

Introduction: The aim of this study was to investigate the effect of angiotensin II (Ang II) and losartan injections into paraventricular nucleus (PVN) on renal ischemia-reperfusion injury. Methods: After right nephrectomy in male rats, a cannula was inserted into the right PVN. One week later, renal ischemia-reperfusion (IR) injury was induced by clamping the left renal artery for 45 min, a...

Abstract Background Primary graft dysfunction (PGD) remains a major obstacle after lung transplantation. Ischemia–reperfusion injury is known contributor to the development of PGD following We developed novel approach assess impact increased pulmonary blood flow in large porcine single-left transplantation model. Materials Twelve left transplants were divided two groups ( n = 6, low- (LF) and h...
