postconditioning is a simple and safe strategy for cardioprotection and infarct size limitation. our previous study showed that oxytocin (ot) exerts postconditioning effect on ischemic/reperfused isolated rat heart. the aim of this study was to investigate the involvement of ot receptor, mitochondrial atp-sensitive potassium channel (mkatp), nitric oxide (no) and cyclooxygenase (cox) pathways i...

objective(s):acute kidney injury (aki), a syndrome characterized by decreased glomerular filtration, occurs in every 1 of 5 hospitalized patients.  renal ischemia-reperfusion, one of the main causes of aki, is of particular importance in the setting of kidney transplantation. materials and methods: sixty male rats were divided into four groups including control, nephrectomy, sham surgery and re...

Objective(s): Obestatin is a newly discovered peptide with antioxidant activities in different animal models. Recent studies have shown that Obestatin inhibits apoptosis following cardiac ischemia/reperfusion injury. Brain ischemia/reperfusion induces irreversible damage especially in the hippocampus area. This study aimed at examining the protective impact of Obestati...

Ischemia-reperfusion injury is the tissue damage caused when blood supply returns to the tissue after a period of ischemia or lack of oxygen. Ischemia-reperfusion brain injury initiates an inflammatory response involving the expression of adhesion molecules and cytokines. Twenty–four male Wistar rats (250-300 g body wt) were used in this study. The animals were divided into four groups of 6 rat...

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...

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...

Case presentation: S.B. is a 48-year-old man who suffered an acute anterior myocardial infarction and received fibrinolytic therapy. The patient died 12 hours after reperfusion. K.R. is a 68-year-old diabetic woman who underwent conventional coronary artery bypass graft surgery and developed low output syndrome after reperfusion postoperatively. V.A. is a 55-year-old man who developed a stunned...

The objective of the research was to study signs oxidative stress, state proteolysis, and proteinase-inhibiting system blood plasma in rats with streptozotocin-induced diabetes mellitus (60 mg/kg intra-abdominally), complicated by cerebral ischemia-reperfusion. Levels products lipid peroxide oxidation, protein modification, nitrogen oxide metabolites, activity antioxidant protection enzymes wer...
