[Nonspecificity of antiviral protein action].

The authors studied the antiviral activity of the informative RNA of antiviral protein (M-RNA AVP) isolated from the cells following superinduction of interferon in them for the purpose of ascertaining the action specificity of the product of their translation--AVP. Following the administration of M-RAN AVP a marked (from 1 to 5 lg PFU/mil) reduction of the infectious titres was observed in the homologous and heterologous cells. RNA preparations from control (noninduced) cells possessed a weak (0.4--0.1 lg PFU/mil) antiviral activity.
