Abstract:

Oxidative stress and inflammation play an important role in hypertensive animals and patients. Hydrogen plays a role of antioxidation and anti-inflammation. Calcium and magnesium play an important role in reducing hypertension and antioxidant. Filtered water contains abundant hydrogen and a large number of other essential elements of the human body. We investigated the protective effects of filtered water on hypertensive mice. To establish hypertension model, ICR mice were administered with N-nitro-L-arginine methyl ester (L-NAME) hydrochloride 64 mg/kg per day for 1 month. The hypertensive mice were, respectively, administered with pure water, tap water, and filtered water for 2 months. Lipid peroxidation, antioxidant enzymatic activity, endothelin-1 (ET-1), angiotensin II (Ang II), and pro-inflammatory cytokines (TNF-α, IL-6, and IL-1β) were assessed. Expressions of phosphorylated NF-κB P65 in the kidney were analyzed by western blot. qRT-PCR analysis was adopted to determine the expression levels of the pro-inflammatory cytokines and NF-κB P65. The results demonstrated that filtered water can reduce the blood pressure. Filtered water treatment restored the activity of antioxidant enzymes, downregulated ET-1, and Ang II in the serum of mice. Filtered water treatment suppressed pro-inflammatory cytokines and decreased the mRNA expression of TNF-α, IL-6, IL-1β, and NF-κB P65. Consumption of filtered water inhibited the expression of NF-κB P65. This suggests that filtered water can reduce the blood pressure. The protection mechanisms include downregulating oxidative stress and inhibiting inflammation, which is partly due to the inhibition of the NF-κB signaling pathway.
