A new model of temporary focal neocortical ischemia in the rat.
BACKGROUND AND PURPOSE We describe a new rat model of temporary focal ischemia that produces neocortical ischemia without the need for prolonged anesthesia. METHODS Temporary focal cerebral ischemia was initiated during halothane anesthesia, maintained for varying periods without anesthesia, and reversed by clip removal requiring brief anesthesia. Tandem carotid and middle cerebral artery occ...
متن کاملEffect of pentoxifylline on brain edema in a rat model of transient focal cerebral ischemia
Pervious studies have shown that pentoxifylline (PTX) has beneficial effects in reduction of stroke and brain trauma injuries in experimental animals. However, there is very little and controversial information about the effect of PTX on brain edema in cerebral ischemia. Therefore, the aim of this study was to determine the effects of different doses of PTX on brain edema and neurological m...
متن کاملFunctional evaluation of temporary focal cerebral ischemia: experimental model.
OBJECTIVE Despite cerebral ischemia being a frequent clinical pathologic state, the tolerance of neural tissue to oxygen absence and to reperfusion is controversial. This study aims to evaluate the effects of focal cerebral ischemia/reperfusion, by analyzing the mitochondrial respiration. METHOD Sixty-four adult rats underwent focal cerebral ischemia by middle cerebral artery occlusion, durin...
متن کاملQuantitative evaluation of Blood Brain Barrier permeability in transient focal cerebral ischemia in the rat
Introduction: Development of brain edema following focal cerebral ischemia exacerbates primary ischemic injury. Blood brain barrier (BBB) opening is an important part of edema named as vasogenic brain edema. In this study, quantitative alterations of BBB permeability is experimentally evaluated using transient focal cerebral ischemia in the rat. Methods: Two groups of male rats (ischemic and sh...
متن کاملPre-Ischemic Treatment of Pentoxifylline Reduces Infarct Volumes in Transient Focal Cerebral Ischemia in the Rat
Background: Pentoxifylline (PTX) is used in human for intermittent claudication and cerebral vascular disorders including cerebrovascular dementia. It also inhibits the synthesis of tumor necrosis factor-α (TNF-α), which is believed to be neurotoxic in animal models of cerebral ischemia. The objective of this study was to examine the role of PTX on ischemia/reperfusion injures in rat model of t...
