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 کاملGABA and benzodiazepine receptors in the gerbil brain after transient ischemia: demonstration by quantitative receptor autoradiography.
Quantitative receptor autoradiography was used to measure the binding of gamma-aminobutyric acid (GABA) and benzodiazepine receptors after ischemia by means of transient occlusion of bilateral common carotid arteries in the gerbil. [3H]Muscimol was used to label the GABAA receptors and [3H]flunitrazepam to label central type benzodiazepine receptors. In the superolateral convexities of the fron...

متن کاملOpioid peptide levels in gerbil brain after transient ischemia: lasting depletion of hippocampal dynorphin.
Peptides derived from each of the 3 endogenous opioid precursors were measured in gerbil brain regions at various times after transient bilateral carotid artery occlusion using radioimmunoassays specific for beta-endorphin-, met-enkephalin-, and dynorphin A-related peptides. Lasting changes were observed only in the hippocampus. The most striking effect was on dynorphin A immunoreactivity, whic...
متن کاملDelayed neuronal death in the CA1 pyramidal cell layer of the gerbil hippocampus following transient ischemia is apoptosis.
The CA1 pyramidal neurons in the hippocampus are selectively vulnerable to transient ischemic damage. In experimental animals, the CA1 pyramidal neurons undergo cell death several days after brief forebrain ischemia. It remains, however, unknown whether this delayed neuronal death is necrosis or apoptosis. To investigate the degenerating processes of the CA1 pyramidal neurons in gerbil hippocam...
