A considerable reduction of hepatosplenomegaly and leucocytosis in leukemic rats of the Brown Norway Myeloid Leukemia (BNML) can be achieved by exposure to 50% nitrous oxide/50% oxygen. In this study the differential antiproliferative effect of nitrous oxide, inactivating vitamin B12, on normal and leukemic hemopoiesis was investigated in this rat model. Rats injected with leukemic cells and exposed to nitrous oxide for 10 days showed 30% reduction of hepatosplenomegaly and 50% reduction of leukocytosis. Similarly treated healthy rats showed no signs of impaired hemopoiesis as measured by peripheral blood parameters. Clonogenic assays of erythroid and myeloid progenitors from both healthy and leukemic rats revealed that exposure to nitrous oxide did not suppress normal bone marrow functioning. On the contrary, the reduction of leukemic proliferation by nitrous oxide retarded the leukemic infiltration of the bone marrow compartment.
