[Effect of sensitization and delayed hypersensitivity reaction on tumor growth in mice].

Mice BALB/c during 8--10 weeks were sensitized by percutaneous injections of BCG vaccine or living B-243 staphylococci weekly, and after 10 days they were inoculated isogenic adenocarcinoma "Akatol". Compared with the control animals the tumor growth was found to be retarded. A more considerable retardation of the growth and in 50% the complete tumor regression was noted in sensitized mice, which repeatedly, since the day of inoculation, were injected subcutaneously or intratumorously alttuberculin or staphylococcic phagolysate, respectively.
