Abstract
Transmembrane defects were found to be formed in donor blood erythrocy tes during their freeze-thawing in the non-penetrating cryoprotective medium (0.13 M polyethylene. oxide with molecular mass of 1500 (PEO-15 00), 0.5 M sucrose). Permeability of erythrocyte membranes for ions of Na+, Ca2+, Mn2+ and sucrose molecules also underwent changes. Reparat ive processes were shown to restore membrane barrier properties.
