Efficacy of SLN-GSE on oxidative stress. H441 cells were incubated with three different doses of SLN-GSE and free GSE 24 h (a) 48 h (b) and 72 h (c) before treatment with H2O2, and the relative mean fluorescence (%) was measured by flow-cytometry after incubation with H2DCFDA. d Time course of % MFI at each time point respect to fluorescence obtained in presence of treatment with H2O2 (considered as 100%). Data are shown as mean ± standard deviation of three experiments conducted each in duplicate. *p < 0.05 **p < 0.01 ***p < 0.001 for H2O2 vs all conditions
