| Outline of Final Research Achievements |
Acute Traumatic brain injury (TBI) can transform into a chronic condition and be a risk factor for Alzheimer's diseases, probably through induction of oxidative stress and neuroinflammation. Here, we examined the ability of the antioxidant molecular hydrogen given in drinking water (mHW) to alter the acute changes after TBI in mice. We found that mHW reversed CCI-induced edema, completely blocked pathological tau expression, accentuated an early increase seen in several cytokines but attenuated that increase by day 7, reversed changes seen in the protein levels of aquaporin-4, HIF-1, MMP-2, and MMP-9, but not for amyloid beta peptide 1-40 or 1-42. Treatment with mHW also reversed the increase seen 4 h after CCI in gene expression related to oxidation/carbohydrate metabolism, cytokine release, leukocyte or cell migration, cytokine transport, ATP and nucleotide binding. These results suggest that it could be an easily administered, highly effective treatment for TBI.
