Hydrogen gas reduces HMGB1 release in lung tissues of septic mice in an Nrf2/HO-1-dependent pathway
Background: Lung injury is a vital contributor of mortality in septic patients. Our previous studies have found that molecular hydrogen (H2), which has anti-oxidant, anti-inflammatory, and anti-apoptosis effects, had a therapeutic effect on a septic animal model through increasing expression…
Protective effects of hydrogen inhalation during the warm ischemia phase against lung ischemia-reperfusion injury in rat donors after cardiac death
Background: Successful amelioration of long-term warm ischemia lung injury in donors after cardiac death (DCDs) can remarkably improve outcomes. Hydrogen gas provides potent anti-inflammatory and antioxidant effects against ischemia-reperfusion injury (IRI). This study observed the effects…
Bone regeneration is enhanced by the combined use of acid‐electrolyzed functional water with hydroxyapatite/collagen composite
Hydroxyapatite/collagen (HAP/Col) composite has a nanostructure and composition similar to that of natural bone. Herein, we have evaluated the beneficial effects of acid‐electrolyzed functional water (FW) in combination with HAP/Col composite as an irrigation material in a rat calvarium defect…
Medical Application of Hydrogen in Hematological Diseases
Hydrogen gas has been reported to have medical efficacy since the 1880s. Still, medical researchers did not pay much attention to hydrogen gas until the 20th century. Recent research, both basic and clinical, has proven that hydrogen is an important physiological regulatory factor…
Hydrogen Water on Survival Rate after Fasting in Drosophila Model
In this study, we use a Drosophila model to examine the effect of drinking hydrogen water on survival rate after fasting. The cells produce free radicals to help to absorb nutritious substances due to metabolism, which is a unique phenomenon for biological organisms. But if over the tension of free…
Hydrogen Ion Dynamics of Cancer and a New Molecular, Biochemical and Metabolic Approach to the Etiopathogenesis and Treatment of Brain Malignancies
The treatment of cancer has been slowly but steadily progressing during the last fifty years. Some tumors with a high mortality in the past are curable nowadays. However, there is one striking exception: glioblastoma multiforme. No real breakthrough has been hitherto achieved with this tumor…
Hydrogen gas: from clinical medicine to an emerging ergogenic molecule for sports athletes
H2 has been clinically demonstrated to provide antioxidant and anti-inflammatory effects, which makes it an attractive agent in exercise medicine. Although exercise provides a multiplicity of benefits including decreased risk of disease, it can also have detrimental effects. For example, chronic…
ANTIBACTERIAL, IN VITRO CYTOTOXIC, AND ANTIOXIDANT ACTIVITIES OF ELECTROLYZED OXIDIZING/REDUCING WATER
Objective: Electrolyzed oxidizing/reducing water is popular as health beneficial water in Indonesia. In this study, we examined the level of antibacterial,anticancer, and antioxidant activity of the electrolyzed water.Methods: The efficacy of electrolyzed water produced by Enagic® at six level pH…
Progress in the Use of Molecular Hydrogen for Cancer Treatment
Molecular hydrogen is an effective antioxidant. Numerous studies have demonstrated the therapeutic effects of hydrogen in the treatment of various human diseases. The possibility of using hydrogen in the treatment of cancer was first discovered in 1975, and in recent studies, researchers have…
Hydrogen Gas from Inflammation Treatment to Cancer Therapy
Hydrogen (H2) therapy is a highly promising strategy against several diseases due to its inherent biosafety. However, the current H2 treatment modalities rely predominantly on the systemic administration of the gas, resulting in poor targeting and utilization. Furthermore, although H2 has…
Recent advances in the neuroprotective effects of medical gases
Central nervous system injuries are a leading cause of death and disability worldwide. Although the exact pathophysiological mechanisms of various brain injuries vary, central nervous system injuries often result in an inflammatory response, and subsequently lead to brain damage. This suggests that…
An LCMS-based untargeted metabolomics protocol for cochlear perilymph: highlighting metabolic effects of hydrogen gas on the inner ear of noise exposed Guinea pigs
Introduction Noise-induced hearing loss (NIHL) is an increasing problem in society and accounts for a third of all cases of acquired hearing loss. NIHL is caused by formation of reactive oxygen species (ROS) in the cochlea causing oxidative stress. Hydrogen gas (H2) can alleviate the damage caused…
A green, efficient and precise hydrogen therapy of cancer based on <i>in vivo</i> electrochemistry
Abstract By combined use of traditional Chinese acupuncture Fe needle electrode and in vivo electrochemistry, we achieved in vivo H2 generation in tumors in a controllable manner and exploited it for effective and green therapy of tumors for the first time. The cathodic acupuncture electrodes…
Effects of Hydrogen in Prevention of Corneal Endothelial Damage During Phacoemulsification: A Prospective Randomized Clinical Trial
Purpose: Hydrogen (H2) has been reported to scavenge free radicals, particularly the hydroxyl radical (·OH). Ultrasound oscillation in an aqueous solution produces ·OH. Our recent study demonstrated that H2 dissolved in an irrigation solution prevented corneal endothelial damage during…
Hydrogen gas inhalation enhances alveolar macrophage phagocytosis in an ovalbumin-induced asthma model
Background: Maintaining an airway clear of bacteria, foreign particles and apoptotic cells by alveolar macrophages is very essential for lung homeostasis. In asthma, the phagocytic capacity of alveolar macrophages is significantly reduced, which is thought to be associated with increased oxidative…
Protective effects of a hydrogen-rich solution during cold ischemia in rat lung transplantation
Background: Molecular hydrogen can reduce the oxidative stress of ischemia-reperfusion injury in various organs for transplantation and potentially improve survival rates in recipients. This study aimed to evaluate the protective effects of a hydrogen-rich preservation solution against…
Molecular hydrogen potentiates hypothermia and prevents hypotension and fever in LPS-induced systemic inflammation
Molecular hydrogen (H2) exerts anti-oxidative, anti-apoptotic, and anti-inflammatory effects. Here we 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…
Hydrogen inhibits microglial activation and regulates microglial phenotype in a mouse middle cerebral artery occlusion model
Microglia participate in bi-directional control of brain repair after stroke. Previous studies have demonstrated that hydrogen protects brain after ischemia/reperfusion (I/R) by inhibiting inflammation, but the specific mechanism of anti-inflammatory effect of hydrogen is poorly understood…
