Cytogenetic effects in peripheral blood lymphocytes in descendants of chernobyl disaster liquidators under the impact of mitomycin c in vitro and folic acid in vivo

Data on cytogenetic examinations of the descendans of Chernobyl disaster liquidators (cleanup personnel) have been obtained. It has been established that the level of spontaneous chromosomal aberrations before folic acid administration was 1.8 times higher than that value after its employment (4.45 vs 2.42%, p < 0.01). In lymphocyte cultures treated with mitomycin C accompanied by folic acid, it was 4.5 times higher before their administration (23.95 vs 5.36%, p < 0.001). The data obtained confirm the possibility of stabilizing the genetic apparatus in the descendans of Chernobyl disaster liquidators after folic acid administration.
