BACKGROUND AND PURPOSE We examined the influence of concurrent moderate hypothermia (30 degrees C) and transient forebrain ischemia on the induction of 72-kDa heat-shock protein and neuronal damage in male Wistar rats. SUMMARY OF REPORT Experimental groups included: normothermic with 8 minutes of transient forebrain ischemia (group 1, n = 7), hypothermic without ischemia (group 2, n = 9), and...

this study intended to assess the efficacy of acute administration of natural honey on cardiac arrhythmias and infarct size when it is used during the normothermic ischemia in isolated rat heart. during 30 min of regional normothermic ischemia followed by 120 min of reperfusion, the isolated hearts were perfused by a modified drug free krebs-henseleit solution (control) or the solution containi...

INTRODUCTION Cold storage of organs for preservation and transplantation is reaching its limits especially with extended criteria for heart beating donors and donation after cardiac death. We will discuss recent findings and perspectives in normothermic kidney preservation. METHODS A literature review was performed from original articles and syntheses selected by the search engine PubMed. Key...

Hypothermia improves clinical outcome after cardiac arrest in adults. Animal data show that a day or more of cooling optimally reduces edema and tissue injury after cerebral ischemia, especially after longer intervention delays. Lengthy treatments, however, may inhibit repair processes (e.g., synaptogenesis). Thus, we evaluated whether unilateral brain hypothermia (∼33°C) affects neuroplasticit...

Background and Purpose: We investigated the effect of hypothermia induced 1 hour after transient (2-hour) middle cerebral artery occlusion on the extent of ischemic cell damage in the rat. Methods: Middle cerebral artery occlusion was induced extracranially by insertion of a nylon filament into the right internal carotid artery. Two groups of rats were investigated: (1) rats (n=10) subjected to...

BACKGROUND Kidney transplantation following uncontrolled donation after circulatory death (uDCD) presents a high risk of delayed graft function due to prolonged warm ischemia time. In order to minimise the effects of ischemia/reperfusion injury during warm ischemia, normothermic recirculation recently replaced in situ perfusion prior to implantation in several institutions. The aim of this stud...

BACKGROUND AND PURPOSE It is not known whether a combination of intraischemic and postischemic mild hypothermia provides extra neuroprotection and if so, whether the neuroprotection is persistent. METHODS Sixty-eight Sprague-Dawley rats were used. In group 1, ischemia and reperfusion were performed under normothermic (N) conditions (control, N-N). In group 2, ischemia was induced and maintain...

The role of cerebral depolarizations in focal cerebral ischemia is unknown. We therefore measured the direct current (DC) electrical activity in the cortex of Wistar rats subjected to transient occlusion of the middle cerebral artery (MCA). Focal ischemia was induced for 90 min by insertion of an intraluminal filament to occlude the MCA. To modulate cell damage, we subjected the rats to hypothe...
