THE RADIOSENSITIVITY OF THE PROCESSES OF DNA-SYNTHESIS IN MOUSE SPLEEN

Journal Article · · Intern. J. Radiation Biol.
The effect of different doses of x rays on DNA-synthesis in mouse-spleen lymphocytes during the synthetic period was studied in vivo and in vitro. DNA- synthesis was measured by the incorporation of H/sup 3/ or C/sup 14/-thymidine. The data confirmed that the radiosensitivity is markedly greater in vivo. The discrepancy was not readily remedied by fortification of the incubation medium by energy-producing substances, and the increased depression did not seem to be due to the release of DNA-metabolites or an inhibitor of DNA-synthesis by the intact spleen. A triphasic response for lymphocytes in vivo is postulated to explain the greater radiosensitivity. (auth)
