Arecoline reduces the cell viability of HGFs. The cells were treated with different concentrations of arecoline (0, 10, 100, 200, 500, and 1 000 μmol·L⁻¹). The cell viability was monitored by MTT assay, and the optical densities (OD) at 570 nm were measured (n=6). The data are shown as the mean±standard deviation. *P<0.05 relative to the control treatment group (0 μmol·L⁻¹). HGF, human gingival fibroblast.
