Prevention of ischemia-induced hearing loss by hydrogen-rich saline

In Animal studies, Eye / Ear by CHESS

Hydrogen-rich water, which is a potent antioxidant agent, was investigated for its protective effects against ischemic damage of the cochlea in gerbils. The animals were subjected to transient cochlear ischemia by occluding the bilateral vertebral arteries for l5min. Five milliliters of hydrogen-rich saline was then intravenously administered immediately after the insult. Saline without hydrogen was used as a control. Effects …

Neuroprotective potential of molecular hydrogen against perinatal brain injury

In Animal studies, Nervous system by CHESS

Exposure to inflammation in utero is related to perinatal brain injury, which is itself associated with high rates of long-term morbidity and mortality in children. Novel therapeutic interventions during the perinatal period are required to prevent inflammation, but its pathogenesis is incompletely understood. Activated microglia are known to play a central role in brain injury by producing a variety of …

Immersing lungs in hydrogen-rich saline attenuates ischaemia–reperfusion injury

In Animal studies, Lung by CHESS

Anti-oxidant effects of hydrogen have been reported in studies examining ischaemia–reperfusion injury (IRI). In this study, the authors evaluated the therapeutic efficacy of immersing lungs in hydrogen-rich saline on lung IRI. Lewis rats were divided into three groups: (i) sham, (ii) normal saline and (iii) hydrogen-rich saline. In the first experiment, the left thoracic cavity was filled with either normal …

Molecular hydrogen decelerates rheumatoid arthritis progression

In Animal studies, Inflammation by CHESS

Rheumatoid arthritis (RA) is a chronic inflammatory disease which results in progressive destruction of the joint. In this study, the authors examined if the hydrogen could inhibit inflammation in a mouse model of collagen-induced arthritis (CIA) via oxidative stress on RA-FLSs. Moreover, to identify the mechanisms of action, the authors evaluated the effect of hydrogen on RA-FLSs development and the …

Protective effects of hydrogen against low-dose long-term radiation

In Animal studies, Other studies by CHESS

Molecular hydrogen (H2) has been previously reported playing an important role in ameliorating damage caused by acute radiation. In this study, the authors investigated the effects of H2 on the alterations induced by low-dose long-term radiation (LDLTR). All the mice in hydrogen-treated or radiation-only groups received 0.1 Gy, 0.5 Gy, 1.0 Gy, and 2.0 Gy whole-body gamma radiation, respectively. After the last time of …

Neuroprotective effect of hydrogen gas on brain injury

In Animal studies, Nervous system by CHESS

Hydrogen gas is widely considered to be a novel antioxidant. It has been demonstrated that inhalation of hydrogen gas reduced ischemic cerebral injury in several investigations. However, it remains unclear whether the neuroprotective effect of hydrogen gas is reproducible in a rat transient forebrain ischemia model. The current study was conducted to evaluate the effect of hydrogen gas on histological …

Lung inflation with hydrogen reduced lung injury

In Animal studies, Lung by CHESS

Lung ischemia-reperfusion injury (IRI) may be attenuated through carbon monoxide (CO)’s anti-inflammatory effect or hydrogen (H2)’s anti-oxidant effect. In this study, the effects of lung inflation with CO, H2, or both during the cold ischemia phase on graft function were observed. Rat donor lungs, inflated with 40% oxygen (control group), 500ppm CO (CO group), 3% H2 (H2 group) or 500ppm …

Gaseous hydrogen improves myocardial dysfunction

In Animal studies, Cardiovascular by CHESS

Immediate inhalation of hydrogen (H2) has been demonstrated to improve post-resuscitation (PR) myocardial dysfunction. In this study, the authors investigated the effects of delayed treatments with H2 on myocardial dysfunction in a porcine model of cardiac arrest (CA). Twenty male pigs weighing 39 ± 2 kg were utilized. Ventricular fibrillation was electrically induced and untreated for 10 min. All the …

Hydrogen inhalation improves survival in hemorrhagic shock

In Animal studies, Cardiovascular by CHESS

Hemorrhagic shock is a life-threatening condition. In addition to conventional treatments such as hemostasis and fluid resuscitation, further investigations are warranted to develop more effective treatments. The study investigated the effectiveness of hydrogen (H2) gas inhalation in a fixed-pressure model of hemorrhagic shock in rats. Hemorrhagic shock is induced by withdrawing blood from the left carotid artery until the mean …

Inhaled hydrogen ameliorates bowel dysfunction

In Animal studies, Gut by CHESS

Gastrointestinal dysmotility frequently occurs during sepsis and multiple organ failure, remaining a major cause of morbidity and mortality in critically ill patients. Previous studies have shown that hydrogen, a new therapeutic gas, can improve various organ damage associated with sepsis. In this study, the authors investigated the protective efficacy of inhaled hydrogen against lipopolysaccharide (LPS)-induced ileus. Sepsis was induced in …
