Mouse Thymocyte Beta-Glucuronidase Activity after Whole-Body X-Irradiation

摘要

Beta-glucuronidase activity of mouse thymocytes, at various time intervals after a single whole-body sublethal dose of X-rays (600 rad), was studied. Activity per cell showed an initial peak at day 2, a maximum by day 7 and returned to normal levels by day 11. Concomitant cell volume distribution analyses were carried out; the data were interpreted to indicate a positive correlation of changes in B-glucuronidase activity with changes in the medium and large thymocyte populations.
