Inhibition of the mean-effect of combination treatment on BGC-823, MKN-45, MGC-803 and HGC-27 cell lines. After exposed to combination of WOG and CDDP/PTX at a fixed ratio (WOG IC50:CDDP/PTX IC50 were 1:1) for 48 h. The values of CI were calculated by the predescribed method. A and B were WOG combined with CDDP and PTX, respectively. CI <1 indicates synergism.
