Abstrakt: We studied the effects of benzo(a)pyrene on lymphocyte chromatin in mice with experimental desynchronosis. Desynchronosis altered chromatin structure in immune system cells and suppressed the immune response. In mice with experimental desynchronosis, benzo(a)pyrene produced more pronounced changes in the chromatin structure compared to the control. It was inferred that light-dark cycle disturbances impair the resistance of organs and systems to damaging environmental factors.
