Hydrogen and lung injury in sepsis

In Animal studies, Lung by CHESS

The aim of this study was to investigate the key role of nuclear factor E2-related factor 2 (Nrf2) in the treatment of lung injury in sepsis mice by regulating Nrf2/heme oxygenase-1 (HO-1)/high mobility group protein B1 (HMGB1) pathway. 120 male wild type (WT) and 120 Nrf2 knockout (Nrf2-KO) ICR mice were randomly divided into Sham group, H2 control group (Sham+H2 …

Hydrogen in mitigating oxidative-stress-induced radiation injury

In Review papers by CHESS

Uncontrolled production of oxygen and nitrogen radicals results in oxidative and nitrosative stresses that impair cellular functions and have been regarded as causative common denominators of many pathological processes. In this review, we report on the beneficial effects of molecular hydrogen in scavenging radicals in an artificial system of •OH formation. As a proof of principle, we also demonstrate that …

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 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 …

FoxO1 and neuroprotective effects of hydrogen in vascular dementia

In Animal studies, Nervous system by CHESS

Vascular dementia (VD) is a heterogeneous group of brain disorders in which cognitive impairment is attributed to cerebrovascular pathologies. Autophagy, a self-cannibalization mechanism, has been demonstrated to be involved in VD progression. Molecular hydrogen is known for its powerful anti-oxidative, anti-apoptotic, and anti-inflammatory activities, and it is also involved in autophagy. However, the effects of hydrogen on VD remain unclear. …

Hydrogen-rich water affects antioxidant activity and gut flora in soccer players

In Exercise, Human studies by CHESS

Expending a considerable amount of physical energy inevitably leads to fatigue during both training and competition in football. An increasing number of experimental findings have confirmed the relationship between the generation and clearance of free radicals, fatigue, and exercise injury. Recently, hydrogen was identified as a new selective antioxidant with potential beneficial applications in sports. The present study evaluated the …

Hydrogen protects against hepatic injury

In Animal studies, Liver by CHESS

Hydrogen-rich saline (HRS) has antioxidative, anti-inflammatory and anti-apoptotic properties. The authors investigated the effects of hydrogen on hepatic ischemia-reperfusion (I/R) and laparoscopic hepatectomy in swine. Twenty-one healthy Bama miniature pigs were randomly divided into the sham group, ischemia-reperfusion injury (IRI) group, HRS-5 (5 mL/kg) group, and HRS-10 (10 mL/kg) group. HRS was injected through the portal vein 10 min before reperfusion and at …
