摘要
目的 :研究银杏内酯对实验性小动物脑缺血的保护作用。方法 :采用小鼠断头模型和大鼠急性不完全性脑缺血模型 ,测定小鼠断头后喘息时间和大鼠脑指数及脑含水量、脑毛细血管通透性以及血液流变学指标 ,观察银杏内酯对实验性脑缺血的保护作用。结果 :银杏内酯可延长小鼠断头后喘息时间 ;降低大鼠脑指数及脑含水量 ,抑制其脑毛细血管通透性升高 ,明显改善血液流变学指标 ,降低血液粘度。结论 :银杏内酯可预防实验性脑缺血损伤。
OBJECTIVE:To study the protective effects of Ginkgolides(GL)on cerebral ischemia in experimental rodents. METHODS:The models of decapitative mice and acute incomplete cerebral ischemic(AICI)rats were used.The gasp duration of decapitative mice and cerebral index,water content of brain,cerebral capillary permeability and hemorrheological parameters in rats were determined.RESULTS:Ginkgolides could prolong gasp duration of decapitative mice,increase the cerebral index and the water content of brain,inhibit capillary permeability,improve hemorrheological parameters and decrease blood viscosiˉty.CONCLUSION:Ginkgolides may antagonize the damage of cerebral ischemia.
