  • Abstract
  • Look Inside

Mouse interferon (IFN) induced in L 929 cells by Newcastle disease virus was examined for its effect on the growth of mouse brain tumor cell line. In this study, we used subcutaneously trans-planted 203 Glioma model, which had been origi-nally induced by methylcholanthrene in C 57 BL mice. After subcutaneous transplantation, intrape-ritoneal administration of IFN was started byfollowing schedule ; 5×103 IU twice a week, 5×104 IU twice a week, 2.5×105 IU twice a week, 5×103 IU every day and 2.5×105 IU every day. In all groups treated by IFN intraperitoneally, no inhi-bition of the tumor growth was seen. On the other hand, natural killer (NK) activity was aug-mented by IFN treatment. Therefore, we consi-dered that augmentation of NK activity was not directly correlated with the antitumor effect ofIFN.

Then, local administration was examined. After subcutaneous tumor was recognized, 2.5×104 IU of IFN was injected intratumorally every day. About 20 days later, the tumor decreased its size less than that treated by local injection of saline. It was suggested that the local administration of IFN might be better than the systemic administration.
