Abstract:
Objective:To determine whether mild hypothermia,isoflurane and propofol reduce gultamate release in rat hippocampus brain slices after hypoxia. Method: Brain slices preparations were separated and incubated from rat hippocampus. Glutamate released from rat brain slices during chemical anoxia(100?M KCN)were measured with a fluorescence assay,at 28℃,31℃ and 37℃ after anoxia and after administration of 1 MAC of isoflurane and 200 ?m propofol respectively. Result: Glutamate release was significantly reduced at 28℃ or 31℃ compare with that at 37℃ (P
