Effects of HHQ on the plasma levels of a NO metabolites (NOx; NO2− and NO3−) and b eNOS mRNA expression in the liver and the thoracic aorta. Mice 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). The P value for the trend (Ptrend) was calculated using the Jonckheere trend test
