Abstract:
Objective To investigate the effects of long-term ionizing radiation on T,B and NK lymphocyte subsets in peripheral blood of male roentgenography workers.
Methods The T,B and NK lymphocyte subsets in the peripheral blood lymphocyte of 32 male roentgenography workers were examined and compared among stratified groups with gradient radiation dose.
Results There were significant difference (t=2.430,P<0.05) between the percents of CD3+CD8+T cells in lymphocyte of ≤ 20 mSv group(24.91& #177;7.21)%versus >20 mSv group(18.68& #177;6.99)%.The percents of CD8+CD45RO+T cells in lymphocyte between ≤ 20 mSv group(6.54& #177;2.65)%versus>20 mSv group(4.15& #177;1.93)% were significantly different also (t=2.780,P<0.01).
Conclusion Reduction of CD3+CD8+T and CD8+CD45RO+T subsets of lymphocyte may be resulted in long-term ionizing radiation in male roentgenography workers.Attention in monitoring on these changes should be enforced.
