ELECTRON MICROSCOPIC STUDY OF THE INFLUENCES OF X-IRRADIATION ON BONE MARROW CELLS
In rats receiving LD50 doses of x irradiation, the sensitivity to x rays were generally high in young cells, next in mature normoblasts, then lymphocytes and granulocytes, and low in monocytes and plasmocytes. The sensitivity to x rays of the fine structural cell components was highest in mitochondria followed by microsomes, external nuclear membrane, Golgi bodies, and nucleus. Vacuole formation after x irradiation was observed in the cytoplasm or nuclear membrane or both. In the mitochondria, irregularity of the crista, pyknosis, vacuole formation, deformation and swelling were observed. In the Golgi bodies enlargement of the Golgi field and increase in number of vacuoles were observed. In the nucleus transparency due to nodulation of chromatin or pyknosis was observed. In the nuclei of myelocytes and metamyelocytes, nucleoli with string- shaped irregular boundary membranes appeared. In eosinophils the crystalline inner ends of the eosinophilic granules disappeared.
