Summary

Transmembrane defects were found to be formed in donor blood erythrocytes during their freeze-thawing in the non-penetrating cryoprotective medium (0.13 M polyethylene oxide with molecular mass of 1,500 (PEO-1,500), 0.5 M sucrose). Permeability of erythrocyte membranes for ions of sodium+, calcium2+, magnesium2+, and sucrose molecules also underwent changes. Reparative processes were shown to restore membrane barrier properties.
