Potentiation of antitumor effect of bleomycin by local electric pulses in mouse bladder tumor.
C3H mice bearing subcutaneously transplanted mouse bladder carcinoma (MBT-2) were treated with intramuscular injection of bleomycin followed by local delivery of electric pulses at the tumor site. The tumors markedly reduced and even disappeared for several days after this treatment. Neither electric pulses nor bleomycin administration alone showed a significant inhibitory effect on the tumor growth. Thus, it is demonstrated that in mouse bladder tumor the antitumor effect of bleomycin can be considerably potentiated by local electric pulses.
