Data are shown as mean ± SD (n = 10). 1.000 cells for MN and CAs numbers and 10.000 cells for MI were analyzed in each group. Control and treatment group data were compared with each other and there was a statistically significant difference between the values indicated with * sign (p < 0.05), there was no significant difference between the values indicated with ** sign (p > 0.05). MI: mitotic index, SC: sticky chromosome, VC: vagrant chromosome, B: bridge, NB: nucleus bud, UDC: unequal distribution of chromatin, FRG: fragment, NV: nucleus with vacuole, MN: micronucleus.
