EFFECT OF REPEATED WHOLE-BODY X-IRRADIATION ON THE PERIPHERAL WHITE BLOOD CELL COUNT OF RABBITS

摘要

Then followed a third application of the same doses with subsequent observation of white counts J Statistical analysis of data yielded the following results: In the three exposures, radiation-induced leukopenia showed no significant difference with respect to rate of development, maxima degree, and rate of disappearance. Therefore, as judged by the white blood cell count, susceptibility to ionizing radiation appeared unaltered by previous exposure to appreciable doses when the interval between exposures was sufficiently long to permit complete hematopoietic recovery.
