title: [Accidental involution of the thymus after splenectomy (an experimental study)].
abstract: Using immunological, general clinical and luminescent histochemical methods experimental study of immunological status and bioamine-containing thymus structures was performed on third, seventh and fifteenth postsplenectomy days in 90 outbred albino male rats. Splenectomy leads to significant changes in blood immunological parameters and morphofunctional state of thymus bioamine-containing structures. Significant increase of biogenic amines content in all thymus structures, leukocyte number, complement activity neutrophilic granulocytes phagocytic activity, were registered in 3 days. Further growth of bioamine content, decrease of cortical and medullary substances diameter, significant number growth of juvenile forms of mast cells were observed in 7 days. Essential decline in erythrocyte number, hemoglobin and IgG and IgA content, leukocytosis with leukemoid reaction development were defined in blood formula. On 15th postsplenectomy day maximal biogenic amine concentration, especially histamine was reached and further reduction in cortex and medulla as well as decline of all the immunoglobulins and decrease of neutrophilic granulocytes phagocytosis were determined. Thus, splenectomy and subsequent development of accidental involution leads to secondary immunodeficiency and severe anemia.
