本文采用结扎小鼠双侧颈总动脉１ｈ，同时在距尾尖１ｃｍ处剪断其尾放血数滴，继之再灌流２４ｈ，造成小鼠全脑缺血再灌流的损伤。观察枸杞多糖对脑缺血再灌流小鼠学习、记忆能力的影响。结果表明，枸杞多糖可显著提高脑缺血再灌流小鼠的学习、记忆能力，并促进其学习、记忆能力的恢复。 In this paper, ligation of bilateral common carotid arteries in mice 1h, at the same time at the tail from the tail cut a few drops of blood tail, followed by reperfusion 24h, resulting in cerebral ischemia-reperfusion injury in mice. To observe the effects of Lycium barbarum polysaccharides on learning and memory in cerebral ischemia-reperfusion mice. The results showed that LBP can significantly improve the learning and memory ability of mice with cerebral ischemia and reperfusion and promote their learning and memory recovery.
