Molecular hydrogen consumption in the human body during the inhalation of hydrogen gas

In Human studies, Metabolism by CHESS

Inhaling or ingesting hydrogen (H2) gas improves oxidative stress-induced damage in animal models and humans. It has been previously reported that H2 was consumed throughout the human body after the ingestion of H2-rich water and that the H2 consumption rate (VH2) was 1.0 ╬╝mol/min/m(2) body surface area. To confirm this result, authors evaluated VH2 during the inhalation of low levels …

Transperitoneal administration of hydrogen suppress peritoneal and systemic oxidative stress

In Human studies, Kidney by CHESS

Oxidative stress (OS) related to glucose degradation products such as methylglyoxal is reportedly associated with peritoneal deterioration in patients treated with peritoneal dialysis (PD). However, the use of general antioxidant agents is limited due to their harmful effects. This study aimed to clarify the influence of the novel antioxidant molecular hydrogen (H2) on peritoneal OS using albumin redox state as …

Hydrogen-rich water as ergogenic agent

In Exercise, Human studies by CHESS

Possible appliance of effective and safe alkalizing agent in the treatment of metabolic acidosis could be of particular interest to humans experiencing an increase in plasma acidity, such as exercise-induced acidosis. In the present study authors tested the hypothesis that the daily oral intake of 2L of hydrogen-rich water (HRW) for 14 days would increase arterial blood alkalinity at baseline …

Hydrogen-rich water affected rate of acidosis induced by exercise in young healthy men

In Exercise, Human studies by CHESS

Metabolic acidosis is a clinical disturbance characterized by low pH in body tissues and blood and a variety of neuromuscular and cardiorespiratory responses. Besides treating the initial disorder, the main goal for patients with acidosis is to increase the systemic pH with alkalizing agents. The main aims of this study were to investigate whether daily oral administration of 2 L …

Hydrogen-rich water and quality of life in cancer patients receiving radiotherapy

In Cancer, Human studies by CHESS

Cancer patients receiving radiotherapy often experience fatigue and impaired quality of life (QOL). Many side effects of radiotherapy are believed to be associated with increased oxidative stress and inflammation due to the generation of reactive oxygen species during radiotherapy. Hydrogen can be administered as a therapeutic medical gas, has antioxidant properties, and reduces inflammation in tissues. This study examined whether …

Acute brain stem infarct sites treated with edaravone and hydrogen

In Human studies, Nervous system by CHESS

In acute stage of cerebral infarction, MRI indices (rDWI & rADC) deteriorate during the first 3-7 days after the ictus and then gradually normalize in approximately 10 days (pseudonormalization time), although the tissue is already infarcted. Since effective treatments improve these indices significantly and in less than the natural pseudonormalization time, a combined analysis of these changes provides an opportunity …

Drink with hydrogen improves exercise performance in physically active men and women

In Exercise, Human studies by CHESS

In the current study we tested the hypothesis that an acute (7 days) intake of an alkaline negative oxidative reduction potential formulation (NORP) drink would reduce the rate of blood lactate accumulation during and after exercise, increase time to exhaustion, increase serum buffering capacity and not increase prevalence of adverse effects as compared to the control drink. Eleven participants (9 …

Effects of drinking hydrogen-rich water on muscle fatigue in elite athletes

In Exercise, Human studies by CHESS

Muscle contraction during short intervals of intense exercise causes oxidative stress, which can play a role in the development of overtraining symptoms, including increased fatigue, resulting in muscle microinjury or inflammation. Recently it has been said that hydrogen can function as antioxidant, so we investigated the effect of hydrogen-rich water (HW) on oxidative stress and muscle fatigue in response to …

Hydrogen-helium-oxygen mixture in humans during an open sea dive

In Exercise, Human studies by CHESS

Six commercial divers were investigated for neurological and psychosensorimotor responses during an open sea dive to 500 m with a hydrogen-helium-oxygen mixture containing 49% hydrogen. Results showed only moderate neurological symptoms of high-pressure nervous syndrome, whereas the narcotic effect of hydrogen was detectable, as investigated by psychosensorimotor tests. Nevertheless, the divers successfully carried out the main purpose of the operational …

Molecular hydrogen reduces oxidative stress and disease activity in patients with rheumatoid arthritis

In Human studies, Inflammation by CHESS

Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by the destruction of bone and cartilage. Although its etiology is unknown, the hydroxyl radical has been suggested to be involved in the pathogenesis of RA. Recently, molecular hydrogen (H2) was demonstrated to be a selective scavenger for the hydroxyl radical. Also, the method to prepare water containing extremely high concentration …
