Effect of SMT on IL-2- induced IgG (A) and IgM (B) production in PBMC cultures. Cultures established at the indicated time intervals after the treatment were activated at initiation with human recombinant IL-2 (200 U/ml). The levels of immunoglobulin in supernatants collected after 7 days of cultivation were determined by a specific immunoassay. The results are presented as untransformed means of values ± SEM for each of the study groups.
