Viability changes of L-02 cells after arsenic or grape seed procyanidin extract treatment (mean and 95% CI). Cell viability was detected by MTT assay. &12 h versus the control group, ; 24 h versus the control group, ; #48 h versus the control group, . CI: confidence interval. Cell viability decreased significantly with increase in concentration and intervention time of arsenic. GSPE had no significant effect on cell viability.
