There are reports that insulin may protect neurons from the effects of ischemia. The mechanisms for this protection are not fully understood. We studied the extracellular levels of glutamate and GABA in insulin-treated animals exposed to transient forebrain ischemia under normoglycemic and hypoglycemic conditions. In vivo microdialysis technique was used to(More)
Adrenalectomy protects the brain from delayed neuronal damage that occurs following transient forebrain ischemia in gerbils. Gamma-amino butyric acid (GABA) and GABA-mimetic drugs also have a neuro-protective effect. In this study we estimated the extracellular glutamate and GABA levels in the hippocampus during transient forebrain ischemia in(More)
Hypothermia or a glutamate receptor antagonist may offer protection when used before or within seconds of an ischemic insult. In this experiment, we tested the efficacy of hypothermia (34 degrees C) versus CGS-19755 (a potent competitive N-methyl-D-aspartate (NMDA) receptor blocker) and their combination which was administered 0.5 h after a 5-min forebrain(More)
OBJECTIVES Comparison of effectiveness and cost of transcatheter occlusion of patent ductus arteriosus (PDA) with surgical ligation of PDA. METHODS This retrospective comparative study was conducted in the pediatric cardiology department of Ch. Pervaiz Elahi Institute of Cardiology Multan, Pakistan.
