A comparison of methods of determining the 100 percent survival of preserved red cells.

The i phenotype and congenital cataracts among Chinese in Taiwan

Because hydroxyethyl starch (HAES) is used for volume replacement therapy and as a cryoprotectant for frozen red blood cells (RBCs), this compound, in contrast to glycerol, does not require labor-intensive removal from thawed cells prior to transfusion. We here report the effect of both glycerol and HAES on the RBC organic phosphates ATP and 2,3-diphosphoglyceric acid (2,3-DPG). The CPD-A1-stabilized RBCs of 20 healthy donors (3 females, 17 males) were separately frozen in either 40% glycerol or 6% HAES, of molecular weight 200,000. ATP and 2,3-DPG concentrations were determined in CPD-A1 RBCs before addition of cryoprotectant and in cryopreserved thawed RBCs after 24 h storage at -80 degrees C (glycerol) and -196 degrees C (HAES). It appears that HAES, but not glycerol, significantly reduces ATP concentrations whereas both lead to a reduction of 2,3-DPG concentrations; this reduction was more pronounced with glycerol than with HAES. Experiments with the blood of 6 donors demonstrated that HAES affects autohemolysis by 16%, in contrast to glycerol, after which cryoprotectant autohemolysis was affected by 3.1% only. RBC recoveries were comparable using glycerol or HAES as cryoprotectants. A distinct pattern of reduction of 2,3-DPG levels by glycerol and less by HAES, and of ATP levels by HAES but not by glycerol, emerges. Our findings may be of importance if HAES is to be introduced as a convenient cryoprotectant.

Influence of the cryoprotective agents glycerol and hydroxyethyl starch on red blood cell ATP and 2,3-diphosphoglyceric acid levels.
