[Laboratory and clinical study of biological activity of poly G-poly C complex]

Poly(G).poly(C) inoculated intravenously to mice in a dose of 100 microgram induced interferon in the blood in amounts comparable to those induced by poly(I).poly (C). In contrast to rapid accumulation (within 2 hours after induction) and rapid disappearance of interferon in response to poly(I).poly(C) inoculation, the interferon induced by poly(G).poly(C) reached the maximum titer by 6 hours and remained at a high level for 24 hours after inoculation. When given to human volunteers intranasally in a dose of 6 mg, the poly(G).poly(C) complex induced interferon in the blood serum in 70% of the subjects in a titer of 85 units/ml within 24 hours.
