[Cryopreservation of erythrocytes at moderately low temperature with transportation simulation].

Cryopreservation of red cell mass at -75-80 degrees C as concentrates warrants its prolonged storage (up to 1.5 years) in functional condition and transfusion without centrifugation. The above cryoconcentrates are resistant to temperature fluctuations and keep morphologically and functionally safe in response to a temperature rise to -32 degrees C (transportation simulation).

[A comparative study of the cryoprotective properties of dimethylacetamide and dimethyl sulfoxide in preserving thrombocytes at moderately low temperatures].

Comparative characteristics of cryoprotective properties of dimethylacetamide and dimethyl sulfoxide (DMAC and DMSO, respectively), used for freezing and storage of platelets at -80 degrees C, have been presented. It is shown that with the studied final concentrations of the cryoprotectors (5% of DMSO, 2.5% of DMAC), solutions containing DMSO display higher cryoprotective properties.
