Animal StudyIn VitroHighlightedHydrogen acts as a therapeutic antioxidant by selectively reducing cytotoxic oxygen radicalsMHID-7700658PMID: 174860892007Nature MedicineIkuroh Ohsawa, Masahiro Ishikawa, Kumiko Takahashi, Megumi Watanabe, Kiyomi Nishimaki, Kumi Yamagata, et al.Acute oxidative stress induced by ischemia-reperfusion or inflammation causes serious damage to tissues, and persistent oxidative stress is accepted as one of the causes of many common diseases including cancer. We show here that hydrogen (H2) has potential as an antioxidant in preventive and therapeutic applications. We induced acute oxidative stress in cultured cells by three independent methods.
