The purpose of this study was to investigate the effects of limb ischemic preconditioning (LIP) on apoptosis of pyramidal neurons in the CA1 hippocampus induced by global cerebral ischemia-reperfusion in rats. Forty-six rats whose bilateral vertebral arteries were occluded permanently were assigned to one of four groups: sham group, limb ischemia group, cerebral ischemia group and LIP group. LI...
The present study established a rat model of global cerebral ischemia induced by chest compression for six minutes to dynamically observe expressional changes of three glutamate transporters in the cerebral cortex and hippocampus. After 24 hours of ischemia, expression of glutamate transporter-1 significantly decreased in the cerebral cortex and hippocampus, which was accompanied by neuronal ne...
The glutamate excitotoxicity hypothesis of ischemic cell damage holds that cell damage caused by transient cerebral ischemia is triggered by glutamate, released during ischemia from the intracellular compartment into the synaptic cleft: high extracellular glutamate levels activate ionotropic glutamate receptors, thus inducing an overflow of calcium ions into the neurones and a calcium-induced a...
