[Morpho-functional characteristics of normal and pathological human megakaryocytes studied by selective silver staining of cell nucleoli].

The activity of nucleolar organizer (NO) in megakaryocytes (MG) from 8 donors, 10 patients with immune thrombocytopenias (IT), 17 patients with chronic myelocytic leukemia (CML) and 14 patients with multiple myeloma (MM) was studied by silver staining. The average number of nucleoli in MG of normal donors comprised 21.8 per nucleus with a range from 16.
