Engystol-N at the doses of 10(-4) and 10(-8) in isolated human leukocytes stimulates the superoxide anion generation by neutrophils and the cytokine(s) production by T lymphocytes. In whole blood the same concentrations of the drug produce the decrease of the superoxide anion generation of neutrophils, this inhibiting activity appears 6 h after the administration of the drug and persists only in presence of lymphocytes. Culture media of T lymphocytes treated with Engystol-N show the same inhibiting effect on superoxide anion generation by neutrophils. From these data it is possible to conclude that the drug stimulates the secretion of lymphokine(s) with inhibiting action on superoxide anion generation of neutrophils that prevail over the direct stimulating effect, confirming and extending the immunomodulatory ability of the drug.
