We studied changes in phagocytic activity of neutrophils and lymphocytes subjected to cold anabiosis. The proposed effective method for introduction of human blood leukocytes into cold anabiosis at moderately low temperature (-40 o C) in the presence of a cryopreserving agent does not require washout of the biological material after defrosting.

As many as 8 autologic transplantations of the bone marow are performed: 5 patients with hemoblastoses, 1 patient with lymphogranulomatosis and 2 patients with great tumors. The bone marrow is preserved in liquid nitrogen using the programmed freezer with home cryoconservator "Gekmolit". All patients are discharged. One patient with myelogenetic disease died in 70 days after transplantation and disease relapse. The state of the other 7 patients is satisfactory in 927 months.
