Preliminary investigations showed high preventive activity of two of three aerosol preparations of Abies sibirica polyprenols with nonionic surface active substances towards influenza infection. At least 2 aerosol administrations are needed to attain a high protective effect, the second dose depending on the first. Relationship between animal reaction to influenza virus infection changed in a nonmonotonous mode, depending on the drug dose injected during the first treatment: as the dose increased, the death rate first decreased and reached the minimum and then increased again. Such a reaction to aerosol treatment can be explained by the hypothesis of hyperstimulation followed by exhaustion of the host defense systems after high doses of the preparation.
