The modified ADC method which can be used in measuring the survival fraction of L,7712, cells was established using horse serum instead of calf serum. It demonstrated the obvious radiosensitizing effect of metronidazole derivative (CM)on in vitro hypoxic L,7712, cells. Its SER was about 2, and was about 67 percent higher than SER (1.2) of the original compound, metronidazole. CM was found to be stronger under hypoxic condition than under aerated condition in the inhibition of cell survival fraction. It was consistent with the results of the preceeding paper that CM showed a strong ability to sensitize sarcoma 180 to radiation and to inhibit the growth of sarcoma 180 under hypoxic condition. Using trypan blue staining method and the ADC method to observe cell survival were compared.
