DIURNAL FLUCTUATION OF LEUCOCYTE COUNTS OF SUBJECTS WITH RADIATION HAZARDS
To test the supposition that during the day changes occurred in the blood picture of people subject to occupational radiation exposures, workers with marked decreases of leukocyte counts and workers who had recovered from the effects of excessive radiation were selected for study from radiological employees and x-ray techniciane. In the cases of long-standing service with persistent leukopenia, the fluctuations in the counts of total leukocytes, neutrophil cells, and lymphocytes were at the same hour every day and within the day very small. In the cases of comparatively short professional service but with persistent leukopenia, the total leukocyte count showed some perceptible increase in the afternoon and the daily fluctuation in the afternoon hours was also somewhat notable. These changes were always predominantly influenced by the neutrophil cells, for the lymphocyte count remained essentially unchanged. In cases newly diagnosed as leukopenia, the daily difference in the total leukocyte count at the same hours was markedly large, especially in the afternoon hours, in some cases amounting to 3000. This fluctuation showed an increase with the lapse of time. These changes were always under the predominant influence of the neutrophil cells, the lymphocyte count remaining nearly unchanged. In cases recovered from radiation effects, the leukocyte counts at the same hour every day and within the day were found to be nearly at the same level throughout. In these changes the neutrophil cell count changed little, and the change in lymphocyte count was rather large, so that these slight fluctuations of the total leukocyte count seemed to be determined by the behavior of lymphocytes. In exposure cases on the way to recovery, the total leukocyte count steadily increased with the lapse of time, and the daily difference at the same hour was large in the afternoon, with the difference sometimes amounting to 2000. The neutrophil cells were mainly involved in these changes of the total leukocyte count, but the change in lymphocyte counts was also comparatively large. (Absts. Japan. Med., 1: No.7, 1960.)
