Effects of oxymatrine on proliferation of Hep-2 cells. (a) Hep-2 cells were treated with oxymatrine at different concentrations for various times and the OD values were obtained through reading plate at 450 nm with 96-well microtest spectrophotometer by CCK-8 assay. (b) Relationship between the percentage of laryngeal cancer cell proliferation inhibition and different concentrations of oxymatrine. (c) Morphological changes induced by various concentrations of oxymatrine for 24 and 72 h in Hep-2 cells (×100).
