G-banding analysis of chromosome aberrations in Hiroshima atomic bomb survivors (in Japanese and English)

Technical Report ·
OSTI ID:5932425
; ; ;
A total of 896 metaphases obtained from 2-day culture of peripheral blood lymphocytes of 23 heavily exposed atomic bomb survivors of Hiroshima were examined first by an ordinary staining method, and then reexamined after trypsin-G-banding stain. There were 348 metaphases identified as having abnormal karyo-types by either one or both methods. Of these aberrant cells, 293 were found to have chromosome aberrations by the ordinary stain, and 6 of the 293 were identified as normal by G-banding stain, 4 of which were misjudged in the ordinary preparation due to the presence of partially distorted chromosomes. Furthermore, there were 55 metaphases in which abnormalities were detected only by G-banding, including paracentric inversions, and intra- and interchanges of chromosome segments with equal lengths.
