Beneficial effects of hydrogen inhalation in allergic rhinitis

In Animal studies, Inflammation by CHESS

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 …

Breathing hydrogen-oxygen mixture decreases inspiratory effort

In Cardiovascular, Human studies by CHESS

Hydrogen-oxygen mixture (H2-O2) may reduce airway resistance in patients with acute severe tracheal stenosis, yet data supporting the clinical use of H2-O2 are insufficient. The authors evaluated the efficacy and safety of breathing H2-O2 in acute severe tracheal stenosis. Thirty-five consecutive patients with severe acute tracheal stenosis were recruited in this prospective self-control study. Air, H2-O2 and O2 inhalation was …

Hydrogen prevents left ventricular hypertrophy in hypertension

In Animal studies, Cardiovascular by CHESS

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

In Animal studies, Inflammation by CHESS

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 …

Inhalation of hydrogen in Parkinson’s disease

In Human studies, Nervous system by CHESS

Hyposmia is one of the earliest and the most common symptoms in Parkinson’s disease (PD). The benefits of hydrogen water on motor deficits have been reported in animal PD models and PD patients, but the effects of hydrogen gas on PD patients have not been studied. The authors evaluated the effect of inhalation of hydrogen gas on olfactory function, non-motor …

Hydrogen gas reduces chronic hypertension

In Animal studies, Cardiovascular by CHESS

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 …

Hydrogen-controlled cancer

In Cancer, Human studies by CHESS

Advanced cancer treatment is a huge challenge and new ideas and strategies are required. Hydrogen exerts antioxidant and anti-inflammatory effects that may be exploited to control cancer, the occurrence and progression of which is closely related to peroxidation and inflammation. The authors conducted a prospective follow-up study of 82 patients with stage III and IV cancer treated with hydrogen inhalation …

Microbiota response to oral administrations of hydrogen-rich water

In Animal studies, Gut by CHESS

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

In Animal studies, Nervous system by CHESS

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

In Animal studies, Nervous system by CHESS

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 …
