Objective To investigate a new approach of the combined use of trichosanthin (TCS) and recombinant interferon alpha - 2b (rIFN α - 2b) against digestive system cancer cells. Methods Detect separately the cytotoxicity of TCS, rIFN α-2b and their combination against digestive system cancer cell SGC-7901.Results In the experiment in vitro, TCS, rlFN α-2b both had direct, dose dependent cytotoxicity against SGC- 7901. Their combined use demonstrated a toxicity significantly higher than that of the two drugs used alone,showing a significant synergic effect. This synergic cytotoxicity was confirmed in the animal experiment.Conclusion Combined use of TCS and rIFN α- 2b decreases the therapeutic dose of TCS and its toxic adverse effect, and this synergic effect is favorable to the clinical use of TCS protein against gastric cancer.
