作者应用玫瑰花结形成试验的方法观察了人淋巴细胞各亚群的辐射敏感性,试图寻找更敏感的生物剂量测定指标。方法:血液样品采自11名21～25岁的男性供血者。应用葡聚糖-泛影葡胺梯度密度离心的方法从外周血中分离淋巴细胞。细胞悬液分为两部分,一部分照射X线,另一部分作生物对照。照射剂量为100～2500伦。照后2、4、24、48、72小时进行检查。予定照后 The authors used the rosette formation test to observe the radiosensitivity of human lymphocyte subsets and tried to find more sensitive biodosimetry indicators. Methods: Blood samples were collected from 11 male blood donors aged 21 to 25 years. Separation of lymphocytes from peripheral blood using dextran-diatrizoate gradient density centrifugation. The cell suspension was divided into two sections, one was irradiated with X-rays and the other was used as a biological control. The irradiation dose is 100 to 2500 μm. Follow the inspection for 2, 4, 24, 48, and 72 hours. After given photos
