title: [Colony-forming ability of bone marrow hematopoietic cells in mice with transplanted leukemia during administration of carminomycin].
abstract: Effects of carminomycin on the colony-forming ability of bone marrow haemopoietic stem cells (CFUs) were compared in normal mice with steady state and actively regenerating bone marrow, and in P-388 and La leukemia-bearing mice. CFUs assays were performed 24 h after treatment of donor mice with the increasing doses of the drug. Leukemia-bearing mice received carminomycin on the 5th day after transplantation. The dose-effect curves were exponential for CFUS normal mice with both the steady state and active proliferation state of bone marrow. The maximal effect was found 24 h after injection of 0.7 mg/kg of carminomycin (ED50 for CFUS) being more pronounced in regenerating bone marrow. The dose-effect curves for leukemias were also exponential. In the case of La leukemia the killing of CFUs by carminomycin was the highest as compared with P-388 leukemia.
