  • Title: Human sister chromatid exchange caused by methylazoxymethanol acetate.
    Author: Evans LA, Kevin MJ, Jenkins EC.
    Journal: Mutat Res; 1977 Sep; 56(1):51-8. PubMed ID: 593294.
    Abstract:
    The incidence of sister chromatid exchange was determined in human leucocyte cultures treated with methylazoxymethanol acetate. In all individuals examined, treated cultures manifested a significantly higher frequency of sister chromatid exchanges than controls. Two concentrations of MAM AC were tested in blood cultures from nine individuals. The concentrations varied from individual to individual since they were determined by means of individual dose-response curves, which involved [3H]-thymidine incorporation in PHA-stimulated short-term lymphocyte cultures versus MAM AC contraction. The lower concentration was less than the TD50 dose. Compared to control cultures, the lower concentration caused a higher incidence of sister chromatid exchange in eight of nine individuals. The cumulative mean value for all control cultures was 5.32 exchanges per cell while that for cultures treated with the higher concentration was 10.73.
