Inhibition by Lycium barbarum polysaccharides (LBP) on the increase of reactive oxygen species (ROS) in RGC-5 cells induced by cobalt chloride.
Cells were treated with LBP (0.5 mg/mL) for 24 hours and then incubated with 200 μM of CoCl2 for 24 hours. (A) Flow cytometry to detect dichlorofluorescein (DCF) fluorescence intensity; (B) DCF fluorescence intensity chart. Data were presented as the mean ± SD (n = 5) and analyzed by one-way analysis of variance followed by Student-Newman-Keuls test. **P < 0.01.
