Impact of molecular hydrogen on the innate immune activity and survival

In Animal studies, Inflammation by CHESS

Recently, molecular hydrogen has been reported to have a suppressive effect on inflammation in human and rodent models. The aim of this study was to evaluate the preventive effects of hydrogen-rich water (HRW) on zebrafish challenged by Aeromonas hydrophila. The authors have found an increased survival rate of bacteria-challenged zebrafish subjected to the HRW immersion treatment. Furthermore, they have revealed …

Hydrogen-rich water decreases anxiety-related behaviors and oxidative stress

In Animal studies, Nervous system by CHESS

In Japan, the effects of reduced water, such as hydrogen-rich electrolyzed reduced water and natural reduced water, like Hita Tenryosui water®, have been examined. The purpose of the present study was to identify the role of natural reduced water in anxiety and blood biochemical analysis. Natural reduced water and distilled water were administered to rats for 180 consecutive days, and …

Hydrogen-rich saline prevents bone loss in diabetes

In Animal studies, Metabolism by CHESS

As an antioxidant molecule, hydrogen has been received much more attention and reported to be used as the treatment strategy for various diseases. In this study, the authors hypothesize that systemic delivery of hydrogen saline water may improve the reservation of bone tissue in the tibias and femurs of osteoporotic rats caused by diabetes mellitus (DM), which is characterized by …

Hydrogen-rich water prevents cigarette smoke-induced pulmonary emphysema

In Animal studies, Lung by CHESS

Chronic obstructive pulmonary disease (COPD) is predominantly a cigarette smoke (CS)-triggered disease with features of chronic systemic inflammation. Oxidants derived from CS can induce DNA damage and stress-induced premature cellular senescence in the respiratory system, which play significant roles in COPD. Therefore, antioxidants should provide benefits for the treatment of COPD; however, their therapeutic potential remains limited owing to the …

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 …
