[Inhibitory effect of electrochemotherapy on S180 tumor growth and angiogenesis and the possible mechanism].
This study evaluated the effects of electric pulses combined with antitumor drugs on S180 tumor cells. It was found that the growth of S180 sarcoma was inhibited with a maximum inhibition ratio of 95.5% after the use of electric pulses in combination with the injection of bleomycin (BLM), and the blood vessels of tumor were obviously fewer than those of the untreated tumor in vivo. The mitochondria of S180 tumor cells were swollen after the use of electric pulses in combination with adriamycin. The results showed that electrochemotherapy has evident inhibitory effect on the growth of S180 sarcoma and the mechanism may involve the suppression of tumor angiogenesis and changes in the ultrastructures of tumor cells.
