title: [Immunochemotherapy of human gliomas transplanted into nude mice].
abstract: In the first part of this paper, various chemotherapies were performed against oligodendrogliomas subcutaneously transplanted in to nude mice. Vincristine (VCR), adriamycin, and 1000 rads irradiation were effective against this tumors. Concerning these two drugs, dose response effect was observed. And the effect of 1 mg/kg injection of VCR roughly corresponded to that of five weekly injections of 0.2 mg/kg. In the second part of this experiment, single or combined effects of VCR and immunotherapeutic agents including OK-432 (OK), PSK, and recombinant leucocytic interferon (IFN) were examined. Two glioma lines including oligodendroglioma and glioblastoma were used. Following results were obtained from this experiment: 1) Effect of OK and VCR against oligodendrogliomas were as follows: control less than OK local injection (Local) less than OK intraperitoneal injection (IP); VCR; OK (IP X 2) less than VCR + OK(IP) less than VCR + OK (IP X 2). Effects of OK and VCR were expressed in order of their effects against glioblastomas: control less than VCR less than OK (IP); OK(IP X 2); OK(Local) less than VCR + OK (IP); VCR + OK (IP X 2). Effects of PSK and VCR against glioblastomas were as follows: control; PSK (Local) less than VCR less than VCR + PSK (Local) less than VCR + PSK (IP). Effects of IFN and VCR against oligodendrogliomas were as follows: control; IFN (IP) less than VCR less than IFN (Local) less than VCR + IFN (IP); VCR + IFN (Local). Effects of IFN and VCR against glioblastomas were as follows: control less than IFN (IP) less than VCR; IFN (Local); VCR + IFN (IP).(ABSTRACT TRUNCATED AT 250 WORDS)
