研究发现外周血淋巴细胞胞浆分裂阻滞微核（ＣＢ微核）和常规培养微核、化学比色法测定的血清过氧化脂质、超氧化物歧化酶及总抗氧化活性在飞行人员均明显增高． 其中ＣＢ微核与宇宙辐射年均有效剂量、年均飞行小时呈线性关系． 血清过氧化脂质水平也有随二者的增加而增加的趋势， 并和ＣＢ微核一样能灵敏反应近期内飞行负荷的变化． 结果说明： 在宇宙射线的作用下， 飞行人员染色体和基因组的稳定性受到损害， 体内脂质受到氧化损伤； 淋巴细胞ＣＢ微核及血清过氧化脂质可作为飞行人员辐射防护的监测指标．
Study found that peripheral blood lymphocyte cytoplasm division micronuclei (CB micronucleus) and conventional culture micronuclei, serum lipid peroxidation, superoxide dismutase and total antioxidant activity measured by the chemical colorimetry were in flight personnel Significantly higher. Among them, the average effective dose of CB micronuclei and cosmic radiation and the annual average flight hours are linear. Serum lipid peroxidation also increased with both increasing trend, and the same as the CB micronucleus can sensitive response to changes in the recent flight load. The results show that under the action of cosmic rays, the stability of the chromosomes and genomes of pilots is impaired, and the lipid in the body is oxidatively damaged. The micronucleus of lymphocytes and the lipid peroxidation of serum can be used as the monitoring indicators for the radiation protection of pilots.
