Application of molecular hydrogen as a medical treatment in clinical medicine

In Review papers by CHESS

In recent years, it has become evident that molecular hydrogen is a particularly effective treatment for various disease models such as ischemia-reperfusion injury; as a result, research on hydrogen has progressed rapidly. Hydrogen has been shown to be effective not only through intake as a gas, but also as a liquid medication taken orally, intravenously, or locally. Hydrogen’s effectiveness is …

Molecular hydrogen as a neuroprotective agent

In Review papers by CHESS

Oxidative stress and neuroinflammation cause many neurological disorders. Recently, it was reported that molecular hydrogen (H2) functions as an antioxidant and anti-inflammatory agent. The routes of H2 administration in animal model and human clinical studies are roughly classified into three types, inhalation of H2 gas, drinking H2-dissolved water, and injection of H2-dissolved saline. This review discusses some of the remarkable …

Hydrogen-rich saline as an innovative therapy for cataract?

In Review papers by CHESS

Cataract is the leading cause of irreversible blindness worldwide. Increasing evidence indicates that oxidative stress is an important risk factor contributing to the development of cataract. Moreover, the enhancement of the antioxidant defense system may be beneficial to prevent or delay the cataractogenesis. The term oxidative stress has been defined as a disturbance in the equilibrium status of oxidant/antioxidant systems …

Hydrogen-rich saline may be an effective and specific novel treatment for osteoradionecrosis

In Review papers by CHESS

Hydrogen, a therapeutic medical gas, can exert antioxidant activity via selectively reducing cytotoxic reactive oxygen species such as hydroxyl radicals. Hydrogen-rich saline is an alternative form of molecular hydrogen that has been widely used in many studies, including metabolic syndrome, cerebral, hepatic, myocardial ischemia/reperfusion, and liver injuries with obstructive jaundice, with beneficial results. Osteoradionecrosis of the jaw is a serious …

Convenient methods for ingestion of molecular hydrogen: drinking, injection, and inhalation

In Review papers by CHESS

Molecular hydrogen (H2) is clinically administered; however, in some hospitals, H2 is given to patients without consideration of its safe use. In the present study, we prepared convenient and safe devices for the drinking of super-saturated H2 water, for intravenous drip infusion of H2-rich saline, and for the inhalation of H2 gas. In order to provide useful information for researchers …

Ghrelin-mediated benefits and risks of hydrogen

In Review papers by CHESS

Molecular hydrogen (H2) can scavenge hydroxyl radical and diminish the toxicity of peroxynitrite; hence, it has interesting potential for antioxidant protection. Recently, a number of studies have explored the utility of inhaled hydrogen gas, or of hydrogen-saturated water, administered parenterally or orally, in rodent models of pathology and in clinical trials, oftentimes with very positive outcomes. The efficacy of orally …

Hydrogen Molecular Biology and Medicine

In Review papers by CHESS

This book provides a clearly structured introduction to hydrogen biology and medicine. Hydrogen is the one of the most abundant elements in the universe and has the simplest structure. In 2007, Japanese researchers found that the selective oxidation of hydrogen has a therapeutic effect on various diseases and injuries, sparking widespread interest in the biomedical field. In recent years, hundreds …

Molecular hydrogen and radiation protection

In Review papers by CHESS

Molecular hydrogen (dihydrogen, H(2)) acts as a therapeutic antioxidant by selectively reducing hydroxyl radicals (•OH) and peroxynitrite (ONOO-). It has been well-known that ionising radiation (IR) causes oxidative damage and consequent apoptosis mainly due to the production of •OH that follows radiolysis of H(2)O. Authors reported the protective effect of H(2) in irradiated cells and mice for the first time, …

Hydrogen therapy for diabetic erectile dysfunction?

In Review papers by CHESS

Inhalation of hydrogen gas has been proven to be an effective treatment for ischemia-reperfusion injury by selectively reducing hydroxyl and peroxynitrite radicals. There has been considerable evidence of hydrogen’s protective effect against diseases related to oxidative injury, such as the ischemia-reperfusion injury of the brain, liver and heart. More and more studies suggest that radical oxygen species (ROS) play an …
