Cytotoxicity of CDDP and CFC in combination on (A) HeLa, (B) CaSki and (C) Vero. The cells were treated with the appropriate concentrations of CDDP (2, 4, 6, 8, 10,12, 14, 16, 18 and 24 µM) and CFC (20, 50, 100, 200, 400 and 800 µM) for 24 h. Plots of the combination index vs. fraction of cells affected were obtained using the median-effect analysis program. Dashed lines indicate a CI of 1. CDDP, cisplatin; CFC, caffeic acid.
