Abstract

When a bacterial immunopotentiator, OK-432, was injected to intact DDI mice, a viral inhibitor with the properties of immune interferon (IF) was induced in the circulation. The maximum titer of antiviral activity (10,240 units/ml) was observed 24 h after intraperitoneal (IP) injection of 50 KE OK-432/kg body weight. The possibility that the induction of immune IF may depend upon the action of thymus-derived (T) lymphocytes and macrophages was inferred from experiments with thymus-defective nude mice and DDI mice treated with either X-rays or immunosuppressive agents.
