1) OX substance showed marked cytotoxicities in cell suspension culture of Yoshida sarcoma cells, celothelioma cells, and Ehrlich ascites tumor cells. It has become clear that the cytotoxicities have two aspects; one, nuclear shrinkage and karyolisis as seen with Carzinophilin and the other, cytoplasmic swelling as seen with Nitromin. 2) OX substance was effective by its contact action on patients with peritonitis carcinomatosa, celothelioma and rectal carcinoma. 3) Esterified OX substance was injected intravenously or intraperitonealy into CBA mice with ascites leukemia. The substance prolonged their life span and inhibited the progression of leukemia. As it was possible to give the substance repeatedly into mouse tail veins in this experiment, in the future, OX substance might become intravenously injectable for the treatment of patients with leukemia and solid malignant tumors.
