[Storage of platete concentrates at +4 degrees C and +22 degrees C].

The relationship between the conditions of platelet preservation and their ultrastructure, metabolic activity, and the ability to carry out physiological functions was studied. It was found that storage of platelet concentrates at +4 degrees C for 72 hours reduced the number of platelets, changed their shape decreased the ATP level and the ability of release of adenine nucleotides in response to thrombin. The platelet at +22 degrees C for 72 hours preserved the initial number, normal ultrastructure, intact metabolic activity and the ability of participation in heamostasis processes.
