It was established that allergic diseases of poultry farmers were characterized by the shifts in immunoregulation expressed in terms of the decrease of the number of T-lymphocyte-suppressors, precursors of effectory and immunoregulatory T-lymphocytes, reduction of functional actifity of T- and B-cells along with an increase in the content of B-lymphocytes with antibody-dependent killers' sensitization and suppression of nonspecific protective factors. The results suggested that the use of immunomodulatory drugs helped to improve clinicoimmunologic indicators.
