Objective To observe the effects of electromagnetic acute irradiation on PC12 cells. 目的 探讨电磁辐射急性辐照对PC12细胞的影响。
LFA-1 of the BMMNC is high expressed after acute irradiation on the early phase of hematopoietic recovery. 急性放射损伤早期骨髓单个核细胞 L FA 1呈高表达 ;
In the M2 and M3 generation, the average frequencies of mutation in chionic irradiation had increased by 23% and 70% over the acute irradiation of dry seeds respectively. 慢照射M_2、M_3代的平均突变频率比照射种子的分别高23%25
Results The values of D_q,D_0 and SF_2 were 1.54Gy,0.82Gy and(0.448) in acute irradiation group,1.74Gy,0.89Gy and 0.548 in 15 minute irradiation group,1.72Gy,1.00Gy and 0.558 in 30 minute irradiation group,respectively. D0值分别为0.
The total cumulative dose for each groupwas 2.0 Gy. It was found that the types of chromosome aberrations were mainly dicentric abe-rrations and acentric fragments in single acute irradiation. 慢性连续照射以0.
