Objective: The pathogenesis of pulmonary arterial hypertension (PAH) involves reactive oxygen species and inflammation. Beneficial effects of molecular hydrogen, which exerts both anti-inflammatory and antioxidative effects, have been reported for various pathologic conditions. We therefore hypothesized that molecular hydrogen would improve monocrotaline (MCT)-induced PAH in rats.
Methods: Nineteen

Therapeutic effects of molecular hydrogen for a wide range of disease models and human diseases have been investigated since 2007. A total of 321 original articles have been published from 2007 to June 2015. Most studies have been conducted in Japan, China, and the USA. About three-quarters of the articles show the effects in mice and rats. The number of clinical trials is increasing every year. I

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 using these

Molecular hydrogen (H2) is an agent with po- tential applications in oxidative stress-related and/or in- flammatory disorders. H2 is usually administered by inhaling H2-containing air (HCA) or by oral intake of H2- rich water (HRW). Despite mounting evidence, the mole- cular mechanism underlying the therapeutic effects and the optimal method of H2 administration remain unclear. Here, we investigate

Atopic dermatitis (AD) is a chronically relapsing, pruritic, eczematous skin disorder accompanying al- lergic inflammation. AD is triggered by oxidative stress and immune imbalance. In the present study, we in- vestigated the effect of drinking hydrogen water (HW) on 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis in NC/Nga mice and found that HW ameliorated DNCB-induced AD-like clinical

Molecular hydrogen (H2) has been accepted to be an inert and nonfunctional molecule in our body. We have turned this concept by demonstrating that H2 reacts with strong oxidants such as hydroxyl radical in cells, and proposed its potential for preventive and therapeutic applications. H2 has a number of advantages exhibiting extensive effects: H2 rapidly diffuses into tissues and cells, and it is m

A new medical gas, molecular hydrogen (H2), has been reported to be effective for a variety of disorders and clinical trials have shown promising results. Though the precise mechanism is still unknown, it is obvious that H2 has multiple effects. The first prominent effect of H2 was as antioxidant or reactive oxygen species (ROS)-scavenger, though it blocks only hydroxyl radicals (•OH), which are t

Hydrogen exerts beneficial effects in disease animal models of ischemia-reperfusion injury as well as inflammatory and neurological disease. Additionally, molecular hydrogen is useful for various novel medical and therapeutic applications in the clinical setting. In the present study, the hydrogen concentration in rat blood and tissue was estimated. Wistar rats were orally administered hydrogen su

Neuropathic pain remains intractable and the development of new therapeutic strategies are urgently required. Accumulating evidence indicates that overproduction of oxidative stress is a key event in the pathogenesis of neuropathic pain. However, repeated intra-peritoneal or intrathecal injections of antioxidants are unsuitable for continuous use in therapy. Here we show a novel therapeutic method

Traumatic brain injury (TBI) in its various forms has emerged as a major problem for modern society. Acute TBI can transform into a chronic condition and be a risk factor for neurodegenerative diseases such as Alzheimer’s and Parkinson’s diseases, probably through induction of oxidative stress and neuroinflammation. Here, we examined the ability of the antioxidant molecular hydrogen given in drink

Background: Aplasitc anemia (AA) is a bone marrow failure syndrome characterized by an immune-mediated destruction of hematopoietic stem cells. Though clinical symptoms could be ameliorated by bone marrow transplantation and/or immunosuppressive therapy, frequent recurrence and especially evolution of clonal hematologic diseases remains problematic clinically.

Molecular hydrogen (H2) metabolism in bacteria and algae has been well studied from an industrial perspective because H2
is viewed as a potential future energy source. A number of clinical trials have recently reported that H2 is a therapeutic

biological effects remain unclear. In th

It is well known that most of the ionizing radiation-induced damage is caused by hydroxyl radicals (·OH) follows radiolysis of H2O. Molecular hydrogen (H2) has antioxidant activities by selectively reducing ·OH and peroxynitrite(ONOO-).

The therapeutic potential of molecular hydrogen (H2) is emerging in a number of human diseases and in their animal models, including in particular Parkinson’s disease (PD). H2 supplementation of drinking water has been shown to exert disease-modifying effects in PD patients and neuroprotective effects in experimental PD model mice. However, H2 supplementation does not result in detectable changes

Studies on molecular hydrogen have evolved tremendously from its humble beginnings and have continued to change throughout the years. Hydrogen is extremely unique since it has the capability to act at the cellular level. Hydrogen is qualified to cross the blood brain barrier, to enter the mitochondria, and even has the ability to translocate to the nucleus under certain conditions. Once in these i

Whether or not alkaline reduced water (ARW) has a positive effect on obesity is unclear. This study aims to prove the positive effect of ARW in high-fat (HF) diet-induced obesity (DIO) in C57BL/6 mice model. Toward this, obesity was induced by feeding the C57BL/6 male mice with high-fat diet (w/w 45% fat) for 12 weeks. Thereafter, the animals were administered with either ARW or tap water. Next, t
