Abstract

The author investigated dynamic changes in several components of whole blood during storage at 4 C. The results are summarized as follows:1) Glucose and inorganic phosphate in whole blood decreased rapidly during the first four weeks of storage, but lactate increased in value. Relation between glucose and lactate concentration was not stoichiometric.2) Citrate in whole blood showed no change during storage.3) Pyruvate accumulation was shown to rise rapidly after four weeks of storage.4) Oxidation-reduction potential of the pyruvic-lactic acid system was lowered gradually through 4 weeks, and rose slowly thereafter, 5) Carbon dioxide in whole blood showed no increase.6) There was no change in pH of whole blood during storage.
