Solid intraperitoneal Landschütz tumour in mice: implications in cancer chemotherapy and immunology studies.
Multiple intraperitoneal injections of various normal sera into BALB/c mice inoculated intraperitoneally with Landschütz ascites tumour cells abrogated the development of ascitic syndrome in almost all the animals. In a large proportion of the survivors solid intraperitoneal tumours developed, composed of characteristic ascites tumour cells engulfed and encapsulated in connective tissue. The effect of serum on the development of the solid tumour was diminished if the donor had been immunized against mouse IgG. Inoculated animals treated with serum hyperimmune against mouse IgG showed accelerated ascitic tumour growth. Cyclophosphamide or arabinosylcytosine strongly inhibited growth of solid tumours. Simultaneous administration of arabinosylcytosine and its antagonist cycloheximide did not interrupt tumour growth.
