[Biotherapy of experimental tumors with vaccines of Venezuelan encephalomyelitis virus, parotitis and influenza viruses and cytologic evaluation of effectiveness].

Inhibition of experimental tumor growth, life-span, mitotic activity and cytologic damage have been studied in cells of ascitic and solid carcinoma of Ehrlich in the course of biotherapy with vaccines of Venezuelan encephalomyelitis virus, mumps and influenza viruses. Summing up, it is concluded that the vaccine of Venezuelan encephalomyelitis virus looks most promising as far as further research in development of an antitumor viral drug is concerned.
