Abstract

|
It is a well known fact that tumor immunity is mediated by cell-mediated immune reaction and that in the cell-mediated immune raction a small thymus-dependent lymphocyte transforms into a large pyroninophilic cell at the thymus-dependent area-paracortical area of the lymph node and periarterial sheath of the spleen in response to an antigen, which will elicit either a delayed hypersensitivity reaction or an allograft rejection response (Baker et al. , 1962; Parrott et al. , 1966).
Littman et al. (1968) reported that a high level of immunity of a long duration against Ehrlich carcinoma was produced in CFA white Swiss mice by UV-irradiated homologous Ehrlich carcinoma ascites tumor cells and suggested that the immunity produced by irradiated, killed tumor cell vaccine was primarily cell mediated. Kwon and Kim (1972) observed a high level of immunity was produced in mice against subctaneously implanted Ehrlich carcinoma by intraperitonal mounting of diffusion chamber containing live tumor cells.
In this paper an attempt was made to observe the response of thymus-dependent area both of spleen and lymph node of the mice following active immunization with live Ehrlich ascites tumo- cells in diffusion chamber mounted in the peritoneal cavity.
The results were as follows:
In the immune mice, the appearance of large lymphoid cells both in the paracortical area of the lymph node and the periarterial sheath of the spleen was prominent.
