Abstract:
AIM: To demonstrate the protective effects of ST-1 against focal cerebral ischemia-reperfusion injury in rats.METHODS: The model of focal ischemia-reperfusion was induced by middle cerebral artery occlusion 2 h followed by reperfusion 22 h in rats.Neurological deficit scores were evaluated.Infarct size,malondialdehyde(MDA) content and superoxide dismutase (SOD) activity were measured,pathological changes of neurons in hippocampal CA1 region were observed.RESULTS: Compared with vehicle group ST1 at dose of 10 and 20(mg?kg~(-1)) could reduce the infarct size,MDA content,enhance SOD activity and relieve neurons injury in hippocampal CA1 region in dose-dependent way;ST-1 at dose of 20(mg?kg~(-1)) could also improve neurological function.CONCLUSION: ST-1 can protect brain tissue from focal ischemia-reperfusion injury.
