The pronounced progress in the achievement of full remission (in acute myeloid leukemia 58,8%, in acute lymphoblastic leukemia 66%) is revealed in studies of the results of randomizational use of intensive programs of polychemotherapy of 23 patients with acute leukemia. The intensification of the programmed treatment is connected with a high risk of complications. For their decrease the adequate maintaining therapy and the treatment in aseptic wards become necessary.

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.
