Inhaled hydrogen ameliorates bowel dysfunction

In Animal studies, Gutby CHESS

Gastrointestinal dysmotility frequently occurs during sepsis and multiple organ failure, remaining a major cause of morbidity and mortality in critically ill patients. Previous studies have shown that hydrogen, a new therapeutic gas, can improve various organ damage associated with sepsis. In this study, the authors investigated the protective efficacies of inhaled hydrogen against lipopolysaccharide (LPS)-induced ileus. Sepsis was induced in …

Molecular hydrogen for neuroprotection

In Review papersby CHESS

Oxidative stress and neuroinflammation cause many neurological disorders. Recently, it has been reported that molecular hydrogen (H2) functions as an antioxidant and anti-inflammatory agent. The routes of H2 administration in animal model and human clinical studies are roughly classified into three types, inhalation of H2 gas, drinking H2-dissolved water, and injection of H2-dissolved saline. This review discusses some of the …

Hydrogen gas attenuates myocardial ischemia

In Animal studies, Cardiovascularby CHESS

The aim of this study was to investigate the effect of inhaling hydrogen gas on myocardial ischemic/reperfusion(I/R) injury in rats. Seventy male Wistar albino rats were divided into five groups at random as the sham group (Sham). The I/R group (I/R), The ischemic postconditioning group (IPo), The I/R plus hydrogen group (IH2) and the ischemic postconditioning plus hydrogen group (IPoH2). …

Effects of hydrogen gas inhalation on endometriosis

In Animal studies, Other studiesby CHESS

Oxidative stress is generated during the pathophysiology of endometriosis (EMT). Hydrogen (H2) has been demonstrated as a gas antioxidant. The aim of the present study is to evaluate the protective effect of H2 on EMT in rats. Sprague Dawley rats with surgically induced EMT were randomly received the inhalation of 67% H2-33% oxygen (O2) mixture (1 h/d, 4 weeks) immediately …

Hydrogen ameliorates liver injury through PI3K-Akt pathway

In Animal studies, Liverby CHESS

This study explored the hepatoprotection of high concentrations of hydrogen (HCH) inhalation in a mouse hepatic ischemia/reperfusion (I/R) injury model and the potential mechanism. To explore the role of the PI3K-Akt pathway in the hepatoprotection of HCH, C57BL/6 mice were randomly divided into five groups: Sham, I/R, I/R+HCH, LY294002 (PI3K inhibitor)+I/R+HCH, and LY+I/R groups. Mice received inhalation of 66.7% hydrogen …

Hydrogen slows the development of COPD-like lung disease after smoke exposure

In Animal studies, Lungby CHESS

Chronic obstructive pulmonary disease (COPD) is a progressive pulmonary disease caused by harmful gases or particles. Recent studies have shown that 2% hydrogen or hydrogen water is effective in the treatment and prevention of a variety of diseases. This study investigated the beneficial effects and the possible mechanisms of different hydrogen concentrations on COPD. A rat COPD model was established …

Hydrogen as a radical scavenger and a mitohormetic effector

In In vitro studiesby CHESS

Inhalation of molecular hydrogen (H2) gas ameliorates oxidative stress-induced acute injuries in the brain. Consumption of water nearly saturated with H2 also prevents chronic neurodegenerative diseases including Parkinson’s disease in animal and clinical studies. However, the molecular mechanisms underlying the remarkable effect of a small amount of H2 remain unclear. Here, the authors investigated the effect of H2 on mitochondria …

Hydrogen gas inhalation after myocardial infarction

In Cardiovascular, Human studiesby CHESS

Hydrogen gas inhalation (HI) reduced infarct size and mitigated adverse left ventricular (LV) remodeling in a rat model of acute myocardial infarction (AMI). The authors designed a prospective, open-label, rater-blinded clinical pilot study in patients experiencing ST-elevated MI (STEMI). The 20 patients with an initial diagnosis of STEMI were assigned to either an HI group (1.3% H2with 26% oxygen) or …

Molecular hydrogen inhalation attenuates postoperative cognitive impairment

In Animal studies, Nervous systemby CHESS

Postoperative cognitive decline is a major clinical problem with high morbidity and mortality after surgery. Many studies have found that molecular hydrogen (H2) has significant neuroprotection against acute and chronic neurological injury by regulating inflammation and apoptosis. In this study, the authors hypothesized that H2 treatment could ameliorate the development of cognitive impairment following surgery. Adult male rats were subjected …

Molecular hydrogen increases resilience to stress

In Animal studies, Other studiesby CHESS

The inability to successfully adapt to stress produces pathological changes that can lead to depression. Molecular hydrogen has anti-oxidative and anti-inflammatory activities and neuroprotective effects. However, the potential role of molecular hydrogen in stress-related disorders is still poorly understood. The present study aims to investigate the effects of hydrogen gas on resilience to stress in mice. The results showed that …
