Abstract
For the purpose of study of haematopoesis of pregnancy anaemia, relation of erythrocytes' volume and diameter with reticulocytes' maturation was investitated in about 50 cases (17 of them were of Hb. value of 60% or less).
Results were as follows:
1) Group of cases of which Hb, value was more than 60%: Most of them were not so different from normal non-pregnant case in dimension of erythrocytes and maturation of reticulocytes at their initial stages of pregnancy. However, after mid stages of pregnancy, microcytosis and delay of reticulocyte's maturation were found slightly, but maturation was observed partly.
2) Group of cases of which Hb. value was less than 60%: Most of them showed more abnormality in M. C. V., Price-Jone's curve, and in delay of reticulocytes' maturation. Macrocytic anaemia cases showed most remarkable delay of maturation.
3) Grade of anisocytosis was generally parallel to the delay of reticulocytes' maturation.
