[Characteristics of interferon production from the enteral administration of inducers].

When interferon inducers are administered to animals, autonomous local production of interferon by organs (intestine, liver) occurs alongside with the production of serum interferon. After oral administration of a low molecular interferon inducer, tilorone, the intestine is the main site of interferon synthesis. Here the peak of interferon production precedes that in the serum by 20 hours and exceeds it 16-fold. The sequence of events follows the scheme: intestine--liver--serum. Upon oral administration of high molecular inducers incorporated into liposomes (polyguacyl, lafarin) the predominant site of interferon production is the liver where over 80% of the administered inducer is localized and interferon production is 2-4-fold higher than in the intestine. The sequence of events follows the scheme: liver--intestine--serum.
