Frequency of chromosome aberrations induced by trimethyltin chloride in human peripheral blood lymphocytes in vitro: related to age of donors.
Human peripheral blood lymphocytes of healthy male and female individuals of different age groups were treated with two aqueous doses (0.5 microgram and 1.0 microgram) of trimethyltin chloride in mitogen stimulated and serum supplemented culture medium for 72 h at 37 degrees C. Chromatid and chromosome types of aberrations were observed to be increased in both treated sets in all age groups. Significant variations were observed between age groups (P less than 0.001) and between experimental sets (P less than 0.001). Moreover, interaction of chemical and donors age was statistically highly significant (P less than 0.05-P less than 0.001). However, no linear correlation between the increase of donor's age and aberrations was observed.
