In an attempt to elucidate the mechanism of production of macrocytosis in acute anemia, we studied changes in red cell volume and hemoglobin content, the RNA level of normoblasts and reticulocytes and RNA synthesis in reticulocytes of rabbits made anemic by blood loss or phenylhydrazine administration.

Although an elevated erythrocyte mean corpuscular volume has been noted in many conditions, the relative frequency of various causes of macrocytosis in the pediatric population has not been defined. Therefore, the different medical conditions associated with red cell macrocytosis were retrospectively reviewed.
