Effect of HHQ on a serum and b urinary hydrogen peroxide (H2O2) levels in mice that were provided with drinking water [control: white bars, low-HHQ (0.01% HHQ): gray bars, and high-HHQ (0.05% HHQ): black bars] for 4 weeks. Values are the mean ± SEM of N = 7 − 8 mice. Lower-case letters above the bars represent significant differences between the treatment groups (P < 0.05, one-way ANOVA followed by Bonferroni’s post hoc test), and P values of the black bars indicate the significance level relative to the control. The P value for the trend (Ptrend) was calculated using the Jonckheere trend test
