[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. Positive effect of autoplasma in the mixture with the platelet-protecting solution has been manifest in the maintaining of the functional properties of platelets after defrosting.
