The blood picture shows the decrease in whole blood cells, normochromic anemia, reticulocytopenia, thrombocytopenia and increased serum iron. the picture of bone marrow in acute type presents obvious hypoplasia, characterized by the decrease of three blood cell systems and elevation of non-producing blood cells. In chronic type, relatively mild retardation of proliferation may be the feature in bone marrow, associated with right shift of classification.
