BACKGROUND: Bone marrow is extremely vulnerable to damage caused by radiation therapy. Hence, bone marrow suppression is an important side effect of radiotherapy. Effective use of radiotherapy is therefore compromised by radiation-related injuries.MATERIAL AND METHODS: Six Guinea-pigs were recruited for the study of which three were subjected to total body irradiation with Co60 while the other three served as controls. Bone marrow and peripheral blood samples were collected before and at days 9, 14 and 21, post irradiation. Manual and automated counts were performed for bone marrow nucleated cells and peripheral blood cells respectively.RESULTS: Declining bone marrow cellularity was evident immediately post irradiation. Mean ± SD of marrow cell counted per mm3 were 121,924±281, 87,603±772, 121,367±375 and122,750±1000 pre-irradiation and days 9, 14 and 21, postirradiation (p-values 0.10, 0.27 and 0.29 respectively). Significant drops in counts were noticed on day 9 post-irradiation for all red cell parameters (p-values <0.05), for Total White Blood Cell Count and Neutrophil count (p-values <0.05) and also on days 14 and 21 for Lymphocytes (p-values <0.05) and on day 21 for Eosinophil/Basophil/Monocytes (p-value <0.05). A significant drop in platelets counts was also noticed on day 9 (p-value <0.05) which significantly increased above pre-irradiation value on day 21.CONCLUSION: Total body irrradiation with Co60 significantly affects the bone marrow with maximum reductions in marrow nucleated cells and peripheral blood cells counts on day 9 post irradiation.

Marrow Repopulating Ability

Abstract Ten dogs were exposed to 1200 r. of whole body irradiation at a dose rate of 9.2 r./min. Five of these dogs were then given infusions of 21 to 74 x 109 autologous peripheral blood cells which had been previously stored at -80 C. 4.0 to 19.4 x 109 of these cells were lymphocytes, 0.4 to 4.9 x 109 were monocytes and 16.4 to 50.3 x 109 were granulocytes. All five dogs showed clinical or histologic evidence of bone marrow repopulation. The remaining 5 dogs were given 7 to 22 x 109 autologous thoracic duct lymphocytes. In none of these dogs was marrow repopulation observed. It was concluded that hemopoietic stem cells are not present in the thoracic duct lymph of the dog in any appreciable number.

Abstract 1. Adequate chromosome preparations were obtained in 70 per cent of normal rat peripheral blood cell cultures. However, cultures of peripheral blood cells from leukemic rats were almost universally unsuccessful. 2. In x-ray- and 3MCA-induced leukemias direct bone marrow preparations provided adequate metaphases in eight of 12 cases. Failures were attributed in four cases to scanty material obtained from fibrotic marrows. 3. No consistent chromosome abnormalities, such as those reported in human myelogenous leukemia, were found in these leukemic rats. However, the series of cases is small, and species differences and other factors may have influenced the results of these studies.

Histochemical Technique

By means of an indirect histochemical technique, the intracellular lysozyme of the formed elements of the peripheral blood and bone marrow was estimated. Evidence is presented that monocytes, as well as mature neutrophils and their precursors extending back to the progranulocyte, contain significant amounts of this enzyme. A rare mature eosinophil demonstrated a trace of lysozyme activity. There was no evidence of lysozyme activity in basophils, erythrocytes, megakaryocytes, platelets, plasma cells, tissue mast cells or bone marrow reticuloendothelial cells.
