[The frequency of chromosome aberrations in the lymphocytes of children with thyroid diseases living in Bryansk Province].

The number of unstable chromosome aberrations was determined in peripheral blood lymphocytes from 15 children with thyreopathology living in Klintsy (Bryansk Province); the mean age was 14 years. The number of dicentric chromosome is determined to be (0.18 +/- 0.07) per 100 cells and is significantly higher than that in cells from healthy children of Klintsy and Moscow (control). There was no differences in the frequency of other types of chromosome aberrations as well as of aberrant cells.
