[The effect of peripheral cholinergic blockers on the cocarcinogenic action of an experimental influenza infection].

The cocarcinogenic effect of chronic influenza infection was shown to be mediated by M-cholinergic structures. Administration of a M-anticholinergic agent in low dose at the key stages of chronic influenza infection development was followed by a nearly complete suppression of its cocarcinogenic action. N-anticholinergic agents failed to exert such effect.
