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

Background: Early acute kidney injury (AKI) in severely burned patients predicts a high mortality that is multi-factorial. Hydrogen has been reported to alleviate organ injury via selective quenching of reactive oxygen species. This study investigated the potential protective effects of hydrogen against severe burn-induced early AKI in rats.
Methods: Severe burn were induced via immersing the sha

H2 has been suggested to act as an antioxidant when administered just before the reperfusion phase of induced oxidative stress. These effects have been reported, for example, for the heart, brain, and liver. It is hypothesized that this beneficial effect may be due to selective scavenging of HO⋅ and ONOOH by H2. The reaction of H2 with HO⋅ has been studied by pulse radiolysis in the past and is too

Molecular hydrogen (H2) has been reported to be effective for a variety of disorders and its effect has been
ascribed to a selective scavenge of hydroxyl radicals (•OH) at the beginning. Consumption of H2 was either by
inhalation, drinking H2-containing water (H2 water), or infusion of H2-containing saline. Among various disorders,

Molecular hydrogen (H2) scavenges hydroxyl radicals. Recently, H2 has been reported to prevent a variety of diseases associated with oxidative stress in model systems and in humans. Here, we studied the effects of H2 on rat fetal hippocampal damage caused by ischemia and reperfusion (IR) on day 16 of pregnancy with the transient occlusion of the bilateral utero-ovarian arteries.

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-).

Hyperoxic lung injury is a major concern in critically ill patients who receive high concentrations of oxygen to treat lung diseases. Successful abrogation of hyperoxic lung injury would have a huge impact on respiratory and critical care medicine. Hydrogen can be administered as a therapeutic medical gas. We recently demonstrated that inhaled hydrogen reduced transplant-induced lung injury and in

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

Background: There is accumulating evidence that obesity is closely associated with an impaired free fatty acid metabolism as well as with insulin resistance and inflammation. Excessive fatty acid uptake mediated by fatty acid translocase CD36 plays an important role in hepatic steatosis. Molecular hydrogen has been shown to attenuate oxidative stress and improve lipid, glucose and energy metabolis

Background: Molecular hydrogen (H2) as a new medical gas has an anti-inflammatory effect. In the present study, we investigated whether heme oxygenase-1 (HO-1) contributes to the anti-inflammatory effect of H2 in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages.
Methods: RAW 264.7 macrophages were stimulated by LPS (1 mg/mL) with presence or absence of different concentrations of H2. Cell
