title: [Evaluation of the proliferative activity of hematopoietic cells in preleukemic syndromes].
abstract: The Authors have studied bone marrow CFUc and CLFC of 8 cases affected by idiopathic myelofibrosis, 7 by chronic granulocytic leukemia, 6 by polycythemia, and 3 by sideroblastic anemia. The authors studied also C.S.F. activity in peripheral blood of 8 cases. The method of Pike and Robinson for in agar culture was utilized. The results indicated a correlation between increase of clusters/colonies fraction, growth of blasts-like clusters, reduction of C.S.F. activity in peripheral blood and transformation in acute leukemia of preleukemic syndromes.
