Quantitative 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 کاملProtective Effect of Delayed Ischemic Postconditioning on Embolic Stroke Complications in Female Rat
Background & Aims: Ischemic postconditioning, conducted by a series of brief occlusion and release of the bilateral common carotid arteries, has neuroprotective properties in permanent or transient models of middle cerebral artery (MCA) occlusion but its delayed neuroprotective effects in the embolic model of stroke, especially in female rat, have not yet been reported and were investigated ...
متن کاملMicrosphere-induced embolic stroke: an MRI study.
Despite the many studies of the middle cerebral artery occlusion (MCAO) model, efficient therapy for stroke is still lacking, emphasizing the need for further development and characterization of experimental stroke models. In the present study, the rather unexplored multifocal microsphere-induced stroke model in rats was characterized by multiparametric MRI. We induced microembolic infarction i...

Angiogenesis detected after embolic stroke in rat brain using magnetic resonance T2*WI.
BACKGROUND AND PURPOSE This study uses T(2)* weighted imaging (T2*WI) to measure the temporal evolution of cerebral angiogenesis in rats subjected to embolic stroke up to 6 weeks after stroke onset with or without sildenafil treatment. Method- Male Wistar rats were subjected to embolic stroke and treated with saline (n=10) or with sildenafil (n=11), with treatment initiated at 24 hours and cont...
