Effects of cigarette smoke extract (CSE) and ginsenoside Rg1 on the viability of pulmonary fibroblasts. (a) Cytotoxicity of CSE to MRC5 cells was measured using the CCK-8 assay. (b) Effect of ginsenoside Rg1 on cell viability. Values are expressed as the mean ± SD of three independent experiments, each performed in triplicate. and versus the corresponding Sham group.
