objective(s) the aim of this study was to investigate the overall effect of cardiac vasoactive factors during coronary occlusion and reperfusion on peripheral vascular tone, using a sequential isolated rabbit heart-ear perfusion model. materials and methods isolated ears were perfused with the effluent of isolated hearts subjected to ischemia (30 min) and reperfusion (180 min, n=6). the compara...

Abstract: Background: Neuroprotection is one of considerable interest in search novel therapies to improve ischemic brain damage the present scenario. The objective investigation study actions Talinum triangulare cerebral ischemia/reperfusion induced oxidative stress Wistar rats and in-vitro antioxidant actions. Methods: Four different groups adult are selected for where group III IV treated 15...

Objective(s): Liver ischemia-reperfusion injuries (I/RI) are typically the main causes of liver dysfunction after various types of liver surgery especially liver transplantation. Radical components are the major causes of such direct injuries. We aimed to determine the beneficial effects of silibinin, a potent radical scavenger on liver I/RI.Materials...

Resume. The search for new drugs with cytoprotective and anti-ischemic activity is an urgent task of modern pharmacology. These properties are necessary the complex protection renal parenchyma during organ preservation operations (renal resection), most often carried out in conditions thermal ischemia. Only combined use highly effective skill operating surgeon can prevent development acute inju...

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 ...

S-Nitrosylated compounds (nitrosothiols; RS-NOs) function as nitric oxide (NO) reservoirs and preserve the antioxidant activities of NO. We found remarkable cytoprotection by an Snitrosylated protease inhibitor from human plasma, S-nitrosoa1-protease inhibitor (S-NO-a1-PI) that possesses a completely nitrosylated SH group, in hepatic ischemia-reperfusion injuries in rats. Liver ischemia was ind...

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...
