Effect of benzo[a]pyrene on the immune status of mice with anxious-depressive syndrome

We studied the effect of benzo[a]pyrene on cells of lymphoid organs, energy metabolism of blood lymphocytes, and immunological reactivity in mice with anxious depressive syndrome produced by social stress. Benzo[a]pyrene exhibited a more pronounced immunotoxic activity in anxious-depressive animals, which was more than a simple sum of the effects produced by adverse ecological and psychic factors.
