[Biochemical characteristics of concentrated and rinsed erythrocytes].
The biochemical characteristics of concentrated and rinsed out erythrocytes in time function have been analysed. It has been concluded that five days after conservation and during the same day of preparing there was no evidence of significant differences between complete blood erythrocytes and concentrated and rinsed out erythrocytes. In course of preparing concentrated erythrocytes the number of leucocytes declined rapidly, but not completely. By triple rinsing of erythrocytes the number of leucocytes is somewhat less than in the samples of concentrated erythrocytes, but some leucocytes are left.
