[Disturbances of immune status and cytokine profile caused by chronic intoxication with organophosphorus compounds and their correction by administration of imunofan].

Experiments on noninbred rats showed that the chronic intoxication with organophosphorus compounds sarin and methylparathion (30 days; total dose, 0.9 LD50; single daily dose, 0.03 mg/kg,) significantly decreases the immune responses and reduces the concentrations of blood cytokines IFN-gamma, IL-2, IL-4, IL-6, and IL-10. The damage is more pronounced in Th1 cells than in Th2 lymphocytes. The administration of imunofan (single daily dose, 20 microg/kg) for 5 days partly recovers the immune status and the content of cytokines in the blood.
