Aim: to study the effect of reperfusion on organized frequency-amplitude structure ventricular fibrillation (VF) in dog heart. Materials and methods. We conducted 4 experiments 8 dogs. In each experiment, isolated heart one was perfused with blood second (supporting) dog. an artificially heart, 6 episodes 3-minute ischemia 10-minute were performed VF (1-2 ischemia-reperfusion experiment). Each ...

Introduction: This study investigated the effect of berberine on renal dysfunction and histological damages of the lung induced by renal ischemia/ reperfusion at an early stage. Methods: There were four experimental groups of adult male rats (n=7). Seven days before induction of ischemia, the Ber+I/R group received oral (by gavage) berberine (15 mg/kg/day) while the I/R group received distil...

background: the role of nitric oxide (no) of endothelial or neuronal origins in cerebral ischemia and reperfusion injuries are far from being settled, extending from being important to not having any role at all.    objective: to investigate the role of no of endothelial and neuronal origins in ischemia/reperfusion injuries in focal cerebral ischemia, l-name, a non selective no synthase inhibit...

Aim: Our aim was to investigate expression level of VEGF in tuba uterine ovarian ischemia-reperfusion (I/R) by immunohistochemical techniques. Material and Methods: 30 Sprague Dawley female rats were categorized into three groups. Sham group: The abdomen opened closed without any treatment. Ischemia (I) 1-hour ischemia allowed create ischemic injury. Ischemia-reperfusion then 3-hour reperfusion...

Objective(s): The alteration of glucose transporters is closely related with the pathogenesis of brain edema. We compared neuronal damage/death in the hippocampus between adult and young gerbils following transient cerebral ischemia/reperfusion and changes of glucose transporter-1(GLUT-1)-immunoreactive microvessels in their ischemic hippocampal CA1 region. Materials and Methods: Transient cere...

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...

Recent studies have shown that renal ischemia-reperfusion injury can detrimental effects on distant organs such as the brain, liver and lungs. In this study, we aimed to investigate of pancreatic functions.
 Materials Methods. Twenty four male adult Wistar rats were divided into groups. Sham control group animals not given any medications. Animals in groups 3 4 treated with epidural bupiva...

Objective(s):Bradykinin is a part of the kinin-kallikreinsystem which is involved in ischemia-reperfusion injury via B1 and B2 receptors.Noscapine is a non-competitive antagonist of bradykinin receptors. Noscapine has been reported to to be able to protect some organs against ischemia-reperfusion injury but its effect on renal ischemia-reperfusion injury (RIR) in rats is unknown. Therefore, the...
