Effects of three hydrogen-rich liquids on hemorrhagic shock in rats
Background Hydrogen-rich saline provides a high concentration of hydrogen which selectively reduces levels of hydroxyl radicals and alleviates acute oxidative stress in many models. We investigated the protective effects and mechanisms of three different hydrogen-rich liquid resuscitation…
Risks associated with unrestricted consumption of alkaline-reduced water
Consumption of alkaline reduced water produced by domestic electrolysis devices was approved in Japan in 1965 by the Minister of Health, Work and Wellbeing, for the treatment of gastrointestinal disorders. Today, these devices are also freely available in France. The commercial information provided…
Protective effects of hydrogen-rich saline in uncontrolled hemorrhagic shock
Hydrogen is considered to be a novel antioxidant as it inhibits inflammation, removes oxygen-derived free radicals and reduces oxidative damage. This study investigated the effects of hydrogen-rich saline on plasma interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), superoxide dismutase (SOD)…
Multiple Effects of Molecular Hydrogen and its Distinct Mechanism
Molecular hydrogen (H2) has been reported to be effective for a variety of disorders and its effect has been ascribed to a selective scavenge of hydroxyl radicals (•OH) at the beginning. Consumption of H2 was either by inhalation, drinking H2-containing water (H2 water), or infusion…
A review of experimental studies of hydrogen as a new therapeutic agent in emergency and critical care medicine
Hydrogen is the most abundant chemical element in the Universe, but is seldom regarded as a therapeutic agent. Recent evidence has shown that hydrogen is a potent antioxidative, antiapoptotic and anti-inflammatory agent and so may have potential medical applications in cells, tissues and organs…
Intrathecal Infusion of Hydrogen-Rich Normal Saline Attenuates Neuropathic Pain via Inhibition of Activation of Spinal Astrocytes and Microglia in Rats
Background Reactive oxygen and nitrogen species are key molecules that mediate neuropathic pain. Although hydrogen is an established antioxidant, its effect on chronic pain has not been characterized. This study was to investigate the efficacy and mechanisms of hydrogen-rich normal saline induced…
Hydrogen Inhalation During Normoxic Resuscitation Improves Neurological Outcome in a Rat Model of Cardiac Arrest Independently of Targeted Temperature Management
Background— We have previously shown that hydrogen (H 2 ) inhalation, begun at the start of hyperoxic cardiopulmonary resuscitation, significantly improves brain and cardiac function in a rat model of cardiac arrest. Here, we examine the effectiveness of this therapeutic approach when H 2…
Neuroprotective Effect of Hydrogen-Rich Saline against Neurologic Damage and Apoptosis in Early Brain Injury following Subarachnoid Hemorrhage: Possible Role of the Akt/GSK3β Signaling Pathway
Backgrounds: Early brain injury (EBI) plays a key role in the pathogenesis of subarachnoid hemorrhage (SAH). Neuronal apoptosis is involved in the pathological process of EBI. Hydrogen can inhibit neuronal apoptosis and attenuate EBI following SAH. However, the molecular mechanism underlying…
Hydrogen-rich saline attenuates ischemia–reperfusion injury in skeletal muscle
Background: To investigate the potential beneficial effect of hydrogen-rich saline (HRS) in ischemia-reperfusion (IR) injury of skeletal muscle. Methods: Three experimental groups were established in male Sprague-Dawley rats: (1) sham group, (2) IR with normal saline group, (3) and IR with HRS…
Regulative effect of hydrogen on oxidative stress level of placental ischemia-reperfusion cell model of preeclampsia
Objective To investigate the effects of hydrogen on cell protection of placental ischemia-reperfusion cell model of preeclampsia and its possible mechanism. Methods JAR cells cultured in vitro were divided into five groups, i.e. the blank control group, saturated hydrogen group under normal oxygen…
Medical applications of breath hydrogen measurements
In this article, technical developments in breath analysis and its applications in the field of clinical diagnosis and the monitoring of various symptoms, particularly molecular hydrogen in breath, are introduced. First, a brief overview of the current uses of the hydrogen breath test is provided…
Hydrogen gas presents a promising therapeutic strategy for sepsis
Sepsis is characterized by a severe inflammatory response to infection. It remains a major cause of morbidity and mortality in critically ill patients despite developments in monitoring devices, diagnostic tools, and new therapeutic options. Recently, some studies have found that molecular hydrogen…
A novel fluid resuscitation protocol: Provide more protection on acute kidney injury during septic shock in rats
Objective: To investigate the therapeutic effects of a novel fluid resuscitation protocol (early fluid resuscitation plus 2% hydrogen inhalation) on acute kidney injury during septic shock induced by lipopolysaccharide in rats. Methods: Sixty male Wistar rats were randomly divided into four groups…
Hydrogen-rich saline improves survival and neurological outcome after cardiac arrest and cardiopulmonary resuscitation in rats
Background: Sudden cardiac arrest is a leading cause of death worldwide. Three-fourths of cardiac arrest patients die before hospital discharge or experience significant neurological damage. Hydrogen-rich saline, a portable, easily administered, and safe means of delivering hydrogen gas, can exert…
Electrolyzed acid water nasal irrigation after functional endoscopic sinus surgery
Background Electrolyzed acid water (EAW) has been recognized to have strong bactericidal activity, and the feasibility and safety of EAW irrigation in body cavities has been reported in the literature. This study was conducted to evaluate the effect of EAW nasal irrigation on the postoperative care…
Electrochemically reduced water protects neural cells from oxidative damage
Aging-related neurodegenerative disorders are closely associated with mitochondrial dysfunction and oxidative stresses and their incidence tends to increase with aging. Brain is the most vulnerable to reactive species generated by a higher rate of oxygen consumption and glucose utilization compared…
Beneficial Effects of Hydrogen Gas on Porcine Liver Reperfusion Injury With Use of Total Vascular Exclusion and Active Venous Bypass
Background Liver ischemia/reperfusion (I/R) injury is a high risk factor in liver transplantation and it influences graft survival. One of the major events during I/R injury is the generation of cytotoxic oxygen radicals. Recently, hydrogen gas has been reported to have antioxidant properties…
Hydrogen gas attenuates embryonic gene expression and prevents left ventricular remodeling induced by intermittent hypoxia in cardiomyopathic hamsters
The prevalence of sleep apnea is very high in patients with heart failure (HF). The aims of this study were to investigate the influence of intermittent hypoxia (IH) on the failing heart and to evaluate the antioxidant effect of hydrogen gas. Normal male Syrian hamsters ( n = 22)…
Hydrogen extends Caenorhabditis elegans longevity by reducing reactive oxygen species
At present, a large number of studies have reported that hydrogen has antioxidant functions and prevents oxidative stress damage. However, it is not clear whether hydrogen can prolong longevity based on these effects. Therefore, we studied and explored the antiaging potential of exogenous hydrogen…
Hydrogen protects auditory hair cells from cisplatin-induced free radicals
Cisplatin is a widely used chemotherapeutic agent for the treatment of various malignancies. However, its maximum dose is often limited by severe ototoxicity. Cisplatin ototoxicity may require the production of reactive oxygen species (ROS) in the inner ear by activating enzymes specific…
