Cytotoxic effects of 5-FU with or without CDHP on UC cell lines. (A) Cytotoxic effects of various concentrations of 5-FU and (B) 5-FU (10.0 μg/ml) in combination with CDHP (1μg/ml) on 3 bladder cancer cell lines (a; T24, b; UMUC-3 and c; 5637). Cell viability was measured by WST assay. Each value represents the mean derived from at least three individual experiments; bars ± S.E.*, more statistically significant than controls (p < 0.05).
