PG - 391-9 AB - The antitumor activity of lipopolysaccharide (LPS) was investigated in BCG-treated mice. C3H/He mice and CDF1 mice were injected with BCG and then were inoculated with syngeneic mouse hepatoma MH134 and mastocytoma P815 respectively. Hemorrhagic necrosis and retarded growth of tumor were observed after an intravenous (i.v.) injection of LPS, when tumor cells had been inoculated subcutaneously (s.c.). However an intraperitoneal (i.p.) injection of BCG plus LPS did not increase the mean survival time of mice that had been inoculated with tumor cells i.p. Sera from mice that had been treated with BCG plus LPS i.v. were cytotoxic for cultured tumor cells. These results seemed to indicate that growth-inhibitory effects of LPS on tumors inoculated s.c. were mediated by a humoral factor.
