    • Prolonged cold storage of red blood cells by oxygen removal and additive usage. A cost-effective, 4.degree. C. storage procedure that preserves red cell quality and prolongs post-transfusion in vivo survival is described. The improved in vivo survival and the preservation of adenosine triphosphate levels, along with reduction in hemolysis and membrane vesicle production of red blood cells stored at 4.degree. C. for prolonged periods of time, is achieved by reducing the oxygen level therein at the time of storage; in particular, by flushing the cells with an inert gas, and storing them in an aqueous solution which includes adenine, dextrose, mannitol, citrate ion, and dihydrogen phosphate ion, but no sodium chloride, in an oxygen-permeable container which is located in an oxygen-free environment containing oxygen-scavenging materials.
    • 通过除氧和添加剂使用长期冷藏红细胞。 描述了保持红细胞质量并延长输血后体内存活的成本有效的4℃储存方法。 通过改善体内存活和三磷酸腺苷水平的保持,以及在4℃下储存的红细胞的溶血和膜囊泡产生减少延长的时间段,可以通过降低其中的氧水平来实现 存储; 特别是通过用惰性气体冲洗细胞并将它们储存在含有腺嘌呤,葡萄糖,甘露糖醇,柠檬酸根离子和磷酸二氢根离子但不含氯化钠的水溶液中,该容器位于 含氧清除材料的无氧环境。

    • Method using CO for extending the useful shelf-life of refrigerated red blood cells. Carbon monoxide is utilized for stabilizing hemoglobin in red blood cells to be stored at low temperature. Changes observed in the stored cells are similar to those found in normal red cell aging in the body, the extent thereof being directly related to the duration of refrigerated storage. Changes in cell buoyant density, vesiculation, and the tendency of stored cells to bind autologous IgG antibody directed against polymerized band 3 IgG, all of which are related to red blood cell senescence and increase with refrigerated storage time, have been substantially slowed when red blood cells are treated with CO. Removal of the carbon monoxide from the red blood cells is readily and efficiently accomplished by photolysis in the presence of oxygen so that the stored red blood cells may be safely transfused into a recipient.
    • 使用CO延长冷藏红细胞有用保质期的方法。 一氧化碳用于稳定红细胞中的血红蛋白,以在低温下储存。 在储存的细胞中观察到的变化与身体正常红细胞衰老中发现的变化相似,其程度与冷冻储存的持续时间直接相关。 细胞浮力密度变化,囊泡化和存储细胞结合针对聚合带3 IgG的自身IgG抗体的趋势,所有这些都与红细胞衰老有关,并且随着冷冻保存时间的增加而增加,当红血液 用CO处理细胞。通过在氧气存在下通过光解容易且有效地完成从红细胞中去除一氧化碳,使得储存的红细胞可以安全地输入到受体中。
