Clinical application of molecular hydrogen in hemodialysis

In Review papers by CHESS

Increased oxidative stress and pro-inflammatory conditions, commonly present in chronic dialysis patients, are thought to be enhanced during hemodialysis (HD) and to be associated with the excess morbidity and mortality seen in these patients. The hydrogen molecule (H2) has a unique biological capacity to act as an antioxidative and anti-inflammatory substance. In light of accumulating evidence from animal studies showing …

Hydrogen as a therapeutic strategy against photoreceptor degeneration

In Review papers by CHESS

Retinitis pigmentosa (RP) is a heterogeneous group of inherited retinal dystrophies characterized by progressive photoreceptor apoptosis. Reactive oxygen species (ROS) have been recognized as critical initiators of the photoreceptor apoptosis in RP. Photoreceptor survival in RP mutants will not only require the inhibition of effectors of apoptotic machinery, but also the elimination of the initiating upstream signals, such as ROS. …

Hydrogen as a therapeutic strategy against ocular diseases

In Review papers by CHESS

Hydrogen, one of the most well-known natural molecules, has been used in numerous medical applications owing to its ability to selectively neutralize cytotoxic reactive oxygen species and ameliorate hazardous inflammations. Hydrogen can exert protective effects on various reactive oxygen species-related diseases, including the transplantation-induced intestinal graft injury, chronic inflammation, ischemia-reperfusion injuries, and so on. Especially in the eye, hydrogen has …

Melanin as a possible source of bioactive molecular hydrogen

In Review papers by CHESS

Molecular hydrogen (dihydrogen; H2) has traditionally been described as a biologically inactive gas, with low capacity to react with most biomolecules. However, in the past two decades hydrogen emerged as a potent therapeutic agent, with antioxidant, anti-inflammatory and anti-apoptotic effects demonstrated in a plethora of animal disease models and human studies. Prominent effects of supplemental H2 in clinical environment are …

Molecular hydrogen therapy ameliorates organ damage induced by sepsis

In Review papers by CHESS

Since it was proposed in 2007, molecular hydrogen therapy has been widely concerned and researched. Many animal experiments were carried out in a variety of disease fields, such as cerebral infarction, ischemia reperfusion injury, Parkinson syndrome, type 2 diabetes mellitus, metabolic syndrome, chronic kidney disease, radiation injury, chronic hepatitis, rheumatoid arthritis, stress ulcer, acute sports injuries, mitochondrial and inflammatory disease, …

Hydrogen therapy: from mechanism to cerebral diseases

In Review papers by CHESS

The medicinal value of hydrogen (H2) was ignored prior to research illustrating that inhalation of 2% H2 can significantly decrease the damage of cerebral ischemia/reperfusion caused by oxidative stress via selective elimination of hydroxyl freebase (OH) and peroxynitrite anion (ONOO-). Subsequently, there have been numerous experiments on H2. Most research and trials involving the mechanisms underlying H2 therapy show the …

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 …
