Clonal proliferation of lymphoid and myeloid progenitor cells in patients with hematological abnormalities.

Myeloid and lymphoid stem cell colony formation (GM-CFU) and L-CFU) was studied in patients with lymphoproliferative diseases, aplastic anemia and other hematological abnormalities. Most patients with acute lymphatic leukemia had low number of L-CFU with decreased or normal GM-CFU, while in Hodgkin's disease and chronic lymphatic leukemia L-CFU growth was very poor with only minor abnormalities of GM-CFU formation. Aplastic anemia was characterized by a decreased GM-CFU and normal L-CFU. Coculture studies suggested that a diminished colony formation may be linked to circulating lymphocytes that inhibit L-CFU as well as the reduction in number of precursor cells.

[Spontaneous nitroblue terazolium reduction test (NBT) by peripheral blood granulocytes in healthy subjects and in some hematologic syndromes].

The NBT reduction test and determination of alkaline phosphatase activity in the peripheral blood granulocytes (FAG) were done in 94 subjects including 30 blood donors donating blood for the first time and 64 cases of various haematological syndromes. Raised proportion of formazan granulocytes was found in patients with pancytopenia, acute myeloid leukaemia, chronic myeloid leukaemia during blastic exacerbation, Hodgkin's disease during exacerbation and lymphosarcoma. These results correlated with increased FAG activity. Lower proportions of formazan granulocytes capable of spontaneous reduction of NBT were found in patients with chronic myeloid leukaemia, in immunohaemolytic anaemias and in plasmocytoma. Of all the above syndromes only in chronic myeloid leukaemia impaired ability of formazan cell formation parallelled decreased FAG activity. In the remaining syndromes FAG activity in the granulocytes was normal or raised. In the remissions of Hodgkin's disease a fall was observed in the proportion of formazan granulocytes to values of FAG. In chronic myeloid leukaemia the proportion of formazan cells showed considerable fluctuations and no correlation was observed between the proportion of formazan cells and FAG activity.
