title: Alpha1- and beta-adrenoblockers effects on immunogenesis in rats under thermoneutral conditions and after cooling of various extent.
abstract: Experiments with rats showed that ionophoretic delivery of alpha1-adrenoblocker into the skin does not change effects of superficial and deep cooling and did not affect the amount of the antibody producing cells in spleen and a blood level of circulating antibodies under thermoneutral conditions. Meanwhile alpha1-adrenoblocker abolished inhibitory effect of fast deep cooling on antigen-binding properties of spleen cells and peritoneal extraction cells, and markedly stimulated it. beta-Adrenoblocker had no effect on immunogenesis under thermoneutral conditions and changes modulating effect of cooling on immune response. It abolished immunosuppressive effect of deep cooling and enhanced the stimulating effect of superficial cooling. It was true both for antigen-binding processes in spleen and peritoneal cavity and for antibody production in spleen. The results obtained indicate an involvement of alpha1--and beta-adrenoreceptors in immune response inhibition after deep cooling. Adrenoblockers effects on various immune competent cells are ambiguous and depend on temperature.
