Kefir peptides decrease oxidative stress in HFD-induced atherosclerotic ApoE−/−mice. (A) DCF assay to evaluate ROS levels in aortic tissues. Concentrations of (B) nitric oxide (NO) and (C) ox-LDL in serum were detected. Data are displayed as the mean ± SEM (n = 8). The statistical analysis was performed according to Duncan’s multiple-range method. The labels at the top of columns without the same letters indicate significant differences between groups (P < 0.05).
