[Some indices of organism reactivity in chronic trichinellosis].

Sixty four patients who had passed the acute phase of trichinellosis 3, 4, 5 and 8 months and 1, 2 and 4 years earlier, have been examined with respect to their clinical condition, persistence of possible subjective complaints which could be associated with the acute phase passed, leucocytosis, absolute number of acidophilic granulocytes in blood, indices of immunological response, both humoral (IgG, IgA and IgM) and cellular (percentage of T and B lymphocytes in blood), serotonin level in blood, monoamino-oxidase activity in blood serum and passive hemagglutination reaction with trichinellosis antigen. It has been found that the frequency of occurrence and intensity of subjective complaints decreases with time. Changes in humoral and cellular reactivity, and long-lasting persistence of antibodies against the trichinellosis antigen, determined with passive hemagglutination method, have been also observed in particular patients.
