摘要(Abstract)：
观察Xanthone (XT)对小鼠反复脑缺血再灌流后行为学的影响。将 40只小鼠分为 4组 ,经反复脑缺血再灌流加降血压法造模后 ,分别给予注射用水、XT静脉注射高剂量 5 0mg/kg和低剂量 10mg/kg ,术后进行跳台、水迷宫实验测试。结果显示 ,模型组小鼠潜伏期缩短 ,游全程时间延长、错误次数增多 ;XT高、低二个剂量组均使上述指标改善 ,有显著性差异。揭示XT可对抗反复脑缺血再灌流后行为学的障碍 ,学习记忆力的下降
mice models with vascular dementia(VD)were devided into 4 groups and administered respectively with injecting water,XT(10mg/kg,50mg/kg,iv).Observe their behaviors in step-down avoidance test and water-maze test.Results:The mouse's performance in the water labyrinth was obviously affected.The whole distance swimming time was prolonged and mistakes increased.XT can improve the above incidence and there was remarkable difference in statistics.It proved that XT could strengthen the mouse in earning and memory.
