Disclosed is a method and apparatus for regenerating an oxygen-binding ability by reducing the methemoglobin contained in hemoglobin-vesicle by light irradiation. This method comprises adding electron donors such as amino acids, saccharides, alcohols, and/or flavin derivatives in appropriate amounts to the inner aqueous phase of the hemoglobin-vesicle, applying light to the vesicle when the content of methemoglobin increases as a result of oxidation of hemoglobin, thereby reducing the metohemoglobin. In this manner, the oxygen-binding ability is recovered, thereby maintaining the function of the hemoglobin-vesicle.
本发明公开了一种通过光照射还原血红蛋白-囊泡中所含的高
铁血红蛋白来再生氧结合能力的方法和装置。该方法包括在血红蛋白-囊泡的内部
水相中加入适量的电子供体,如
氨基酸、
糖类、
醇类和/或黄素衍
生物,当血红蛋白氧化导致高
铁血红蛋白含量增加时,对囊泡进行光照,从而减少高
铁血红蛋白。这样,氧结合能力就得到了恢复,从而保持了血红蛋白囊的功能。
