Hydrogen-Rich Water Intake Accelerates Oral Palatal Wound Healing via Activation of the Nrf2/Antioxidant Defense Pathways in a Rat Model

Figure 3

Effects of hydrogen-rich water on iNOS expression in rat palatal tissue. (a) Relative mRNA levels of iNOS were detected by real-time PCR. Bars represent mRNA expression levels normalized to GAPDH levels and relative to the control group at 3 days. (b) Representative western blots are shown for iNOS and β-actin. (c) Densitometry results for the bands (iNOS) were normalized to those for β-actin. Data are expressed as mean ± SEM (). , : significantly different from control group at each time point.
