  • Abstract
  • Look Inside

A rat brain tumor model was prepared by im-planting RG-C6 tumor cells in the brain of inbred WKA rat by soft agar technique (Sobue et al., 1977). Tumoricidal effect of peritoneal macrophages from this model was studied in vitro by 3H-uridine technique at various stages of the tumor growth.

Tumoricidal effect (cytotoxicity index) of perito-neal macrophages was rather higher in 12 cases(25.92±9.83: tumor growth index, 11-20) than in 6 cases of the control group (14.00±14.18). It was revealed that its rising tendency came later than the rising phase of cytotoxicity of peripheral blood lymphocytes (tumor growth index, 0-10) which was already reported by authors. This observation has a strong resemblance to other animal tumor models.

On the other hand, comparing the tumoricidal effects of peritoneal macrophages and peripheral blood lymphocytes from rat brain tumor modelwith those from i. p. or s. c. immunized rats, un-doubtedly the former was lower than the latter. In view of these facts, some results were obtained as follows. 1) The induction of killer T cell (effector T cell) was incomplete and 2) differ-entiation of SMAF (Specific Macrophage Activating Factor) producing cell (sensitized T cell) was difficult in the brain. And then I came to a con-clusion that the antigen recognition system of the brain was handicapped.
