In the anaphase of mitosis, many chromosome bridges were observed, some acentric fragments of chromosme lagged behind and were left in cytoplasm. 在细胞分裂后期相中,有较多的染色体桥和无着丝点染色体落后以至散失在细胞质中的现象。
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.
This was mor obvious in the anaphase and telophase, especially in the former phase laggard chromosomes,chromosome bridges,acentric fragments and polypolar distrbution could be seen frequently. 后期主要表现为部分染色体滞后、染色体桥和断片的出现以及染色体不均等的多极分布。末期的主要变化是细胞质的分裂受阻而形成多核体(多核细胞)。
