复方甘油溶液是深低温长期保存红细胞的一种冰冻保护剂。红细胞在体外保存过程中其代谢活动需消耗大量的能量,产生有毒产物。随着保存温度的降低,红细胞的代谢活动逐步减少,直至趋于完全停止。根据这一现象,将低温生物学原理应用于红细胞的保存,可以延长红细胞体外保存的时间和存活率。我国自1970年开始红细胞低温保存的研究,并用于临床输注获得成功〔1〕。笔者为了深低温长期保存红细胞,在红细胞中加入一定量的冰 Glycerol solution is a cryoprotectant for long-term preservation of erythrocytes at deep hypothermia. Red blood cells in the process of preservation of its metabolic activity to be consumed a lot of energy, produce toxic products. As the preservation temperature decreases, the metabolic activity of erythrocytes gradually decreases until it tends to stop completely. According to this phenomenon, the theory of hypobaric biology applied to the preservation of red blood cells, red blood cells can extend the preservation time and survival rate. China since 1970, red blood cell hypothermia preservation research, and for clinical success [1]. The author in order to cryogenic long-term preservation of red blood cells in the red blood cells by adding a certain amount of ice
