摘要: A total of 1328 atomic bomb survivors in Hiroshima were studied to determine alterations the number blood lymphocytes belonging T-cell subpopulations, CD19 antigen-positive B cells and Leu 7 CD16 lymphocytes. Overall, with increasing age, significant decreasing trends numbers some subpopulations observed. Furthermore, positive for CD5 antigen was significantly lower people exposed radiation (greater than 1 Gy) older age group (more 30 years old at time bombing). similar tendency decreases CD4, CD8, observed these survivors, although differences not statistically significant. These results suggest that aging related immune system is accelerated irradiated advanced age. This may be explained by age-related decrease thymic function those subjects who bombing resulting a decreased functional ability after injury. On contrary, or found increased compared younger group, there little dependence on dose.
