Animal StudyHighlightedHydrogen in drinking water attenuates noise-induced hearing loss in guinea pigsMHID-9017895PMID: 208883922010Neuroscience LettersYing Lin, Akinori Kashio, Takashi Sakamoto, Keigo Suzukawa, Akinobu Kakigi, Tatsuya YamasobaIt has been shown that molecular hydrogen acts as a therapeutic and preventive antioxidant by selectively reducing the hydroxyl radical, the most cytotoxic of the reactive oxygen species. In the present study, we tested the hypothesis that acoustic damage in guinea pigs can be attenuated by the consumption of molecular hydrogen. Guinea pigs received normal water or hydrogen-rich water for 14 days
