摘要
A model of cerebral ischemia and reperfusion was established in mice.Mice were treated with ketamine via intraperitoneal injection immediately following ischemia or ischemia/reperfusion.Ketamine did not remarkably change infarct volume in mice immediately following ischemia,but injection immediately following ischemia/reperfusion significantly decreased infarct volume.Ketamine injection immediately after ischemia or ischemia/reperfusion inhibited c-Jun protein expression in mouse hippocampus,but nuclear factor kappa B expression was unaltered.In addition,the Longa scale score for neural impairment was not reduced in mice following cerebral ischemia/reperfusion.These results indicate that ketamine can protect mice against cerebral ischemia and reperfusion injury by modulating c-Jun protein expression in mouse hippocampus.
