Experiments were conducted on rabbits immunized intraperitoneally with corpuscular typhoid vaccine; the number of antibody-forming cells in the spleen proved to increase after tha administration of bacterial lipopolysaccharide (LPS)--pyropeneal, and endogenous serum pyrogen (EPS) together with theopylline. The data obtained indicated that the adenylcyclase system played a certain role in the mechanism of the stimulating action of LPS and EPS.
