Outline of Final Research Achievements

Disorder or diseases in physiology and/or cognitive function are developed by aging and the oxidative stress is one of the factors to affect and induce these diseases. Hydrogen gas is a antioxidative agent. Hydrogen gas is produced by the fermentation of nondigestible saccharide by intestinal microbes, absorbed, and circulate through liver and peripheral tissues. We hypothesize that the ingestion of nondigestible saccharide brings the delaying effect on the onset of these diseases through the antioxidative potentials of the hydrogen which is the metabolite by intestinal microbes.
In the rat with liver disfunction by the excessive Fe or senescence accelerated model mice, the onset of diseases delayed by the intake of nondigestible saccharide. However, these effects were not significant in the case of normal rats. The results suggest that intestinal microbes- derived hydrogen gas is related.
