Primary and secondary myelofibrosis: its relationship to "PNH-like de defect".

Twenty-two patients with primary myeurinary hemosiderin. The defects of lofibrosis and myeloid metaplasia the red cell membrane, as evidenced (MMM) and ten patients with MMM by acid and sucrose lysis tests, were secondary to carcinoma were studied limited to those with primary MMM and for the relationship of MMM to “PNHoccurred in 54#{176}/o of the cases. Another like defect.” Laboratory measurements 10#{176}/o showed decreased haptoglobin included Ham’s test, sucrose hemolylevel, positive sugar-water test, and/or sis test, sugar-water test, leukocyte hemosiderinuria suggestive of the alkaline phosphatase, haptoglobin, and syndrome.
