The percentage of T lymphocytes of atomic bomb survivors showed no change as a function of age or exposure dose. The percentage of T cells was slightly lower in malignant-tumor patients than in the control group, but was significantly higher in the group with chromosomal aberrations than in the control group. The percentages of phytohemagglutinin (PHA)-induced transformation of peripheral lymphocytes decreased significantly with age in the 0 rad control group and the 200+ rad exposure group, particularly so in the latter. The malignant-tumor group also showed lower percentages of PHA-induced transformation than the control group. The percentages of PHA-induced transformation of lymphocytes of the chromosomal-aberration group were significantly depressed as compared with that of the control group.
