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 …
Hydrogen prevents left ventricular hypertrophy in hypertension
Hypertension is an important risk factor for death resulting from stroke, myocardial infarction, and end-stage renal failure. Hydrogen (H2) gas protects against many diseases, including ischemia-reperfusion injury and stroke. The effects of H2 on hypertension and its related left ventricular (LV) function have not been fully elucidated. The purpose of this study was to investigate the effects of H2 gas …
Hydrogen potentiates hypothermia and prevents hypotension and fever
Molecular hydrogen (H2) exerts anti-oxidative, anti-apoptotic, and anti-inflammatory effects. Here, the authors tested the hypothesis that H2 modulates cardiovascular, inflammatory, and thermoregulatory changes in systemic inflammation (SI) induced by lipopolysaccharide (LPS) at different doses (0.1 or 1.5 mg/kg, intravenously, to induce mild or severe SI) in male Wistar rats (250-300 g). LPS or saline was injected immediately before the beginning …
Hydrogen gas reduces chronic hypertension
Molecular hydrogen is reported to be used medically to ameliorate various systemic pathological conditions. This study aimed to investigate the effect of hydrogen (H2 ) gas on hypertension induced by intermittent hypoxia in rats. The adult rats were exposed to chronic intermittent hypoxia (CIH) 8 hours/day for 5 weeks and/or H 2 gas 2 hours/day. The authors found that the …
Microbiota response to oral administrations of hydrogen-rich water
The objective of the current experiment was to explore the intestinal microbiota ecological response to oral administrations of hydrogen-rich water (HRW) and lactulose (LAC) in female piglets fed a Fusarium mycotoxin-contaminated diet. A total of 24 individually-housed female piglets (Landrace × large × white; initial average body weight, 7.25 ± 1.02 kg) were randomly assigned to receive four treatments (six …
Hydrogen attenuates oxidative stress in traumatic brain injury
Several studies have recently found that oxidative stress plays a pivotal role in the pathogenesis of traumatic brain injury (TBI) and may represent a target in TBI treatment. Hydrogen-rich water was recently shown to exert neuroprotective effects in various neurological diseases through its antioxidant properties. However, the mechanisms underlying its effects in TBI are not clearly understood. The purpose of …
Hydrogen-rich water ameliorates autistic-like behavior
Due to its anti-inflammatory and anti-oxidative effects, recent research has demonstrated that molecular hydrogen can serve as a new medical approach for depression, anxiety and traumatic brain injury. However, its potential effects on neurodevelopmental diseases, such as autism are still elusive. The present study aims to investigate the potential effects of hydrogen-rich water (HRW) administration on valproic acid (VPA)-induced autistic-like …
Hydrogen protects the neurons against lead-induced oxidative stress
Despite the well-known toxicity and the efforts to control its exposure, lead still has a serious health concern, particularly in young ages. Chelation therapy cannot correct the neurocognitive effects of chronic exposure. So, there is a requirement to test different protective agents for lead intoxication. Hydrogen-rich water (HRW) has gained attraction recently as an antioxidant. Four groups of rats received …
Hydrogen-rich saline can alleviate the acute kidney injury after severe burns
The main aim of this study was to explore the influences of hydrogen-rich saline on acute kidney injury in severely burned rats and to analyze the related mechanism. Fifty-six Sprague Dawley rats were divided into sham injury group (n=8), burn group (n=24), and hydrogen-rich saline group (n=24) according to the random number table. Rats in sham injury group were treated …
