Molecular hydrogen (H2) has been widely reported to have benefiicial effects in diverse animal models and human disease through reduction of oxidative stress and inflammation. The aim of this study was to investigate whether hydrogen gas could ameliorate endotoxin-induced uveitis (EIU) in rats. Male Sprague-Dawley rats were divided into a normal group, a model group, a nitrogen-oxygen (N-O) group, and …
Hydrogen attenuates progression of chronic heart failure
Continuous damage from oxidative stress and apoptosis are the important mechanisms that facilitate chronic heart failure (CHF). Molecular hydrogen (H2) has potentiality in the aspects of anti-oxidation. The objectives of this study were to investigate the possible mechanism of H2 inhalation in delaying the progress of CHF. A total of 60 Sprague-Dawley (SD) rats were randomly divided into four groups: …
Hydrogen as a novel therapy for severe pressure ulcer
Pressure ulcer formation depends on various factors among which repetitive ischaemia/reperfusion(I/R) injury plays a vital role. Molecular hydrogen (H2 ) was reported to have protective effects on I/R injuries of various internal organs. In this study, the authors investigated the effects of H2 inhalation on pressure ulcer and the underlying mechanisms. H2 inhalation significantly reduced wound area, 8-oxo-dG level (oxidative …
Neuroprotective effects of hydrogen inhalation
Hydrogen inhalation has been found to be neuroprotective and anti-oxidative in several brain injury models. Building on these studies, we investigated potential neuroprotective effects of hydrogen inhalation in a rat model of intracerebral hemorrhage (ICH), focusing on apoptosis and inflammation. Forty-five 8-week-old male Sprague-Dawley rats were randomly divided into three groups (n = 15 per each group): a sham group, …
Hydrogen inhalation improves outcomes in asphyxia induced-cardiac arrest
Cardiogenic global brain hypoxia-ischemia is a devastating medical problem that is associated with unfavorable neurologic outcomes. Low dose hydrogen gas (up to 2.9%) has been shown to be neuroprotective in a variety of brain diseases. In the present study, the authors investigated the protective effect of water by electrolysis-derived high concentration hydrogen gas (60%) in a rat model of asphyxia …
Hydrogen inhalation during EVLP improved donation after cardiac death
Ex vivo lung perfusion (EVLP) is a system that circulates normothermic perfusate into procured lungs, allowing for improved lung function and lung assessment. The authors investigated whether ventilation with hydrogen gas during EVLP improves the donation after cardiac death lung function and whether this effect persists after actual transplantation. Ten pigs were randomly divided into a control group (n = …
Hydrogen ameliorates chronic neurocognitive impairment
Obstructive sleep apnea (OSA) is a very common breathing and sleep disorder characterized by intermittent hypoxia (IH), which is often associated with behavioral and neurocognitive functions impairment. Hydrogen (H2), as a novel and effective antioxidant, is reported to be a potential neuroprotective agent. The aim of this study is to investigate whether H2 could improve CIH-induced neurocognitive impairment and the …
Protective effects of hydrogen gas against sepsis-induced acute lung injury
Lungs are one of the most common target organs of sepsis [1]. Hydrogen gas (H2), which has selective anti-oxidative effects, can be effectively used to treat septic mice. Mitochondrial dysfunction and dynamics play important roles in sepsis-induced organ damage. By using cecal ligation and puncture (CLP), a classic septic model, the study explored the role of 2% H2 treatment in …
Hydrogen reduces acute exercise-induced stress
Physical exercise induces inflammatory and oxidative markers production in the skeletal muscle and this process is under the control of both endogenous and exogenous modulators. Recently, molecular hydrogen (H2) has been described as a therapeutic gas able to reduced oxidative stress in a number of conditions. However, nothing is known about its putative role in the inflammatory and oxidative status …
Beneficial effects of hydrogen inhalation in allergic rhinitis
Allergic rhinitis (AR) is a common chronic inflammatory condition. It has been previously indicated that oxidative stress may contribute to allergic inflammation, including AR. Although molecular hydrogen (H2), an antioxidative agent, has been effective in treatment of numerous oxidative stress-associated diseases, the effect of inhalation of a high concentration of H2 on AR remains unknown. In the current study, female …
