The frequency of chromosome aberrations was studied in peripheral blood lymphocytes of 29 workers occupationally exposed to a mixture of pesticides and in 14 age- and sex-matched healthy controls. There was a significant increase in chromosome aberrations in sprayers when compared to unexposed persons (2.39% compared to 0.54%). No positive correlation(More)

We describe a case of leukemia relapse in a 16-year-old girl 1 year after BMT from her histocompatible brother. Relapse in donor cells was initially suspected on the basis of cytogenetic analysis and confirmed by DNA in situ hybridization in blast(More)
