there was no difference between plws patients and control individuals in the number of chromosome and chromatid aberrations in cells grown at 48 and/or 96 hr in either 20 ng/ml or 50 ng/ml of mmc or between the plws parents and control individuals in cells grown in 50 ng/ml mmc for 96 hr , although a small increase ( p less than 0.05 ) in chromosome breakage was found in cells from the total plws parental group compared with control individuals exposed for 48 hr in 50 ng/ml mmc .
