H3-thymidine and H3-DL-leucine incorporation in the erythroblasts of the
bone marrow from a case of acute and one of chronic Di Guglielmos disease
was studied. A similar investigation was also carried out with bone marrow
from 4 normal subjects. The high resolution of the radioautographic technic
employed allowed a comparative study at the cellular and subcellular level.
A definitely lowered thymidine uptake was observed in the cells of acute
erythremic myelosis, while increased incorporation of DL-leucine was detected
in both the acute and the chronic form of this disease.
