Effect of RD on EC-induced oxidative stress to GSH antioxidant systems in Caco-2 cells. (a) After treatment with 62.5 mM EC in the presence or absence of RE (2 mg/mL) or RD (2 mg/mL) for 24 h. Then cells were collected and incubated with 50 μM NDA at 37°C for 30 min and evaluated by fluorescence microscope. (b) The quantitative data of panel (a) and results were expressed as mean NDA fluorescence intensity (mean ± standard deviations). represents significant difference compared with EC group.
