[Improvement in cryopreservation of blood platelets].

The first Russian solution Krimolit designed for cryopreservation of platelet concentrates down -196 degrees C was clinically tested. The therapeutical efficacy of the cryopreserved platelets was evaluated on the basis of clinical and laboratory monitoring of transfusions in 20 cancer hematological patients. They were found to have the same therapeutical action as fresh cells. The introduction of cryopreserved platelets into clinical practice allows one to form stores and to transfuse autological cells. Krimolit is recommended for clinical application.
