Intraperitoneally administered, hydrogen-rich physiologic solution protects against postoperative ileus and is associated with reduced nitric oxide production
Background: Postoperative ileus, a transient impairment of bowel motility initiated by intestinal inflammation, is common after an abdominal operation and leads to increased hospital stays and costs. Hydrogen has potent anti-inflammatory and antioxidant properties and potential therapeutic value…
Protective effect and mechanism of hydrogen treatment on lung epithelial barrier dysfunction in rats with sepsis
This study aimed to explore the protective effect of hydrogen and to investigate the underlying mechanism of its preliminary effect on the alveolar epithelial barrier function in septic rats. Forty-five male Sprague-Dawley rats were divided randomly into three groups (N = 15): control [saline…
Hydrogen Inhalation is Superior to Mild Hypothermia in Improving Cardiac Function and Neurological Outcome in an Asphyxial Cardiac Arrest Model of Rats
Background: Non-shockable rhythms represent an increasing proportion of reported cases of out-of-hospital cardiac arrest but with an associated poor prognosis. In the present study, we investigated the effects of hydrogen inhalation on cardiac and neurological function after cardiopulmonary…
Hydrogen-rich saline protects against mitochondrial dysfunction and apoptosis in mice with obstructive jaundice
Previous studies have demonstrated that hydrogen-rich saline (HS) protects against bile duct ligation (BDL)-induced liver injury by suppressing oxidative stress and inflammation. Mitochondria, which are targets of excessive reactive oxygen species and central mediators of apoptosis, have a pivotal…
The Effects of Molecular Hydrogen and Suberoylanilide Hydroxamic Acid on Paraquat-Induced Production of Reactive Oxygen Species and TNF-α in Macrophages
The aim of this study is to investigate the effects of molecular hydrogen (H2) and suberoylanilide hydroxamic acid (SAHA), a histone deacetylase inhibitor, on paraquat (PQ)-stimulated production of reactive oxygen species (ROS) and tumor necrosis factor alpha (TNF-α) in macrophages. First, the PQ…
Hydrogen does not Exert Neuroprotective Effects or Improve Functional Outcomes in Rats After Intracerebral Hemorrhage
Aim: Increasing evidence suggests that reactive oxygen species damage the blood-brain barrier and increase brain edema after intracerebral hemorrhage (ICH). Recently, strong clinical and experimental evidence has shown that hydrogen has potent protective cellular effects in various diseases…
Hydrogen-rich water improves neurological functional recovery in experimental autoimmune encephalomyelitis mice
Multiple sclerosis (MS) is a chronic autoimmune demyelinating disease of the central nervous system (CNS). The high costs, inconvenient administration, and side effects of current Food and Drug Administration (FDA)-approved drugs often lead to poor adherence to the long-term treatment of MS…
Hydrogen-Rich Medium Ameliorates Lipopolysaccharide-Induced Barrier Dysfunction via Rhoa-Mdia1 Signaling in CACO-2 Cells
Gastrointestinal barrier dysfunction is associated with the severity and prognosis of sepsis. Hydrogen gas (H2) can ameliorate multiple organ damage in septic animals. Ras homolog gene family member A (RhoA) and mammalian diaphanous-related formin 1 (mDia1) are important to regulate tight junction…
Effect of different acidities of electrolyzed water on dentin surface roughness, decalcification and microhardness —a preliminary study
This study investigated the exposed coronal superficial dentin of 28 human molars were immersed in strongly acidic electrolyzed water (AW group), neutral electrolyzed water (NW group), 5% sodium hypochlorite (negative control, NL group), or deionized water (positive control, DW group)…
Molecular hydrogen affords neuroprotection in a translational piglet model of hypoxic-ischemic encephalopathy
Hypoxic-ischemic encephalopathy (HIE) is the major consequence of perinatal asphyxia (PA) in term neonates. Although the newborn piglet is an accepted large animal PA/HIE model, there is no consensus on PA-induction methodology to produce clinically relevant HIE. We aimed to create…
Effects of Hydrogenized Water on Intracellular Biomarkers for Antioxidants, Glucose Uptake, Insulin Signaling and SIRT 1 and Telomerase Activity
Hydrogen has been shown in several clinical trials to be completely safe without adverse events and there are no warnings in the literature of its toxicity or adverse effects during long-term exposure. Molecular hydrogen has proven useful and convenient as a novel antioxidant and modifier of gene…
Inhibitory Effects of Hydrogen on Proliferation and Migration of Vascular Smooth Muscle Cells via Down-Regulation of Mitogen/Activated Protein Kinase and Ezrin-Radixin-Moesin Signaling Pathways
Molecular hydrogen (H₂) has recently attracted considerable attention for the prevention of oxidative stress-related vascular diseases. The purpose of this study is to evaluate the effects of hydrogen on proliferation and migration of vascular smooth muscle cells (VSMCs) stimulated by angiotensin…
Hydrogen Gas Ameliorates Hepatic Reperfusion Injury After Prolonged Cold Preservation in Isolated Perfused Rat Liver
AbstractHydrogen gas reduces ischemia and reperfusion injury (IRI) in the liver and other organs. However, the precise mechanism remains elusive. We investigated whether hydrogen gas ameliorated hepatic I/R injury after cold preservation. Rat liver was subjected to 48‐h cold storage in University…
Hydrogen, a potential safeguard for graft-versus-host disease and graft ischemia-reperfusion injury?
Post-transplant complications such as graft-versus-host disease and graft ischemia-reperfusion injury are crucial challenges in transplantation. Hydrogen can act as a potential antioxidant, playing a preventive role against post-transplant complications in animal models of multiple organ…
Hydrogen-Rich Saline Attenuates Acute Hepatic Injury in Acute Necrotizing Pancreatitis by Inhibiting Inflammation and Apoptosis, Involving JNK and p38 Mitogen-Activated Protein Kinase–dependent Reactive Oxygen Species
Objectives: The objective of this study was to study the role of hydrogen-rich saline (HRS) on acute hepatic injury (AHI) in acute necrotizing pancreatitis (ANP). Methods: Rats were used for this study and an ANP model was induced by injecting 5% sodium taurocholate into the biliary-pancreatic…
Molecular hydrogen: a therapeutic antioxidant and beyond
Molecular hydrogen (H2) medicine research has flourished since a landmark publication in Nature Medicine that revealed the antioxidant and cytoprotective effects of hydrogen gas in a focal stroke model. Emerging evidence has consistently demonstrated that molecular hydrogen is a promising…
Hydrogen-Rich Water Intake Accelerates Oral Palatal Wound Healing via Activation of the Nrf2/Antioxidant Defense Pathways in a Rat Model
The wound healing process attempts to restore the integrity and function of the injured tissue. Additionally, proinflammatory cytokines, growth factors, and oxidative stress play important roles in wound healing. The aim of this study was to determine whether hydrogen-rich water intake induces…
Oral administration of lactulose: a novel therapy for acute carbon monoxide poisoning via increasing intestinal hydrogen production
It has been known that the pathophysiology of carbon monoxide (CO) poisoning is related to hypoxia, the increased production of reactive oxygen species (ROS) and oxidative stress. Studies have shown that the novel, safe and effective free radical scavenger, hydrogen, has neuroprotective effects…
