“…In the group of treated children, there are some (2,3,4,6,7,8,15,23,26, 28, 32) who fall into the same range as one-third of the non-treated patients; however, all those who had at least one CTE exhibited higher numbers of aberrations. Although there are three nontreated patients (3,5,9) with relatively high numbers of aberrations, mainly CTG and CSG, no exchange-type CA were observed in 900 mitoses of the control cultures.…”
