Abstract
A review of techniques; general metabolic activity of bone marrow cells (the synthesis of deoxyribosenucleic acid, and the metabolism of ribose nucleic acid and protein); special metabolic functions (hemoglobin synthesis in normo-blasts, myeloid cells, mast cells, eosinophil granulocytes, plasma cells, and megakaryocytes); the problems of megaloblasts and leukemic cells; and the physiological and therapeutic agents influencing marrow function.
