Removal of spleen leads to compensatory activation of the function of central immunogenetic organ and increase of hyperplastic processes in it on d 3 postoperatively which is accompanied by growth of biogenic amine concentration, appearance of bioaminergic areas and lobules-satellites as well as formation of new cloe correlative links. Transitory inhibition of immunogenesis occurs on d 15 and d 30 peaking on d 45 following splenectomy. At this period glycosaminoglycan composition of mast cells and their functional activity changes which is manifested by appearance of juvenile T-0 forms and new metachromatic types of mast cells. In 2 months decrease of APUD cells number and their mono- and diamine content and weakening of correlative interconnections is accompanied by true significant disturbance in T lymphocytes differentiation, their release in peripheral blood and further insufficiency of cellular immunity.
