Notes:
We have earlier shown that coculture of macrophages and cells from a methylcholanthiene-induced sarcoma (MCI M-AA) in vitro resulted in macrophage activation and production of type II (gamma) interferon. When ascites fluid from the MCIM-AA sarcoma (shown previously to activate macrophages in vitro) was added to spleen cell populations from semisyngeneic C3D2 mice in vitro. NK activity was markedly enhanced. After intraperitoneal injection of MCI M-AA cells or ascites fluid, 4- to 12-fold increased NK cell activity with a peak at 3–5 days could be measured in the spleen cell population and in the non-adherent peritoneal exudate cell population. The mice injected with tumour cells or ascites fluid developed a pronounced splenomegaly, and maximum spleen size coincided with peak NK activity. Injection of tumour cells or tumour ascites fluid resulted in marked changes in the T-cell, B-cell, macrophage, and ‘null’ cell content of ihe peritoneal exudate.
