摘要: 为了确定应用颅骨外冷冻方法造成大鼠脑冻伤,从而导致血管源性脑水肿的最佳温度及时间,选用了-60、-80及-196℃三个冷冻温度及1、2、3、4min四个冷冻时间冷冻大鼠一侧大脑。结果发现采用-196℃冷冻1min的脑冻伤模型大鼠脑水肿明显,此法操作简单,动物死亡率低。

Abstract: In order to find out the most suitable treatment temperature and time for establishing a rat model of cold - induced vasogenic brain edema, three temperatures (- 60℃、-80℃ and -196℃) and four time (1、2、3、4 minutes) were used. The brass cup, filled with acetone,at the temperature of -60℃、-80℃ and -196℃ was put directly on one side of the rat bony skull resoectuvekt. The results of microscopic and electromicroscopic examinantions revealed that frost at -196℃ for 1 minute, can induce rat brain edema obviously and easily with low mortality.
