The aim of this study was to investigate the protective effect of hydrogen in a rat model of osteoradionecrosis of the jaw (ORNJ). The rats and bone marrow-derived mesenchymal stem cells (BMSCs) were pre-treated with hydrogen before receiving irradiation (7Gy per fraction, five fractions in total once a day for rats, 4Gy for BMSCs). Reactive oxygen species (ROS) and cell …

Degloving injuries represent a challenge in plastic surgery. The aim of this study is to acknowledge the protective effects of hydrogen-rich saline (HRS) solution on a rat hindlimb degloved skin flap. Twenty-one Sprague-Dawley rats were divided into three groups (control, saline and HRS). Degloving injury model was established, and flaps were sutured back following 5 min of ischemia. The control …

Pressure ulcer formation depends on various factors among which repetitive ischaemia/reperfusion(I/R) injury plays a vital role. Molecular hydrogen (H2 ) was reported to have protective effects on I/R injuries of various internal organs. In this study, the authors investigated the effects of H2 inhalation on pressure ulcer and the underlying mechanisms. H2 inhalation significantly reduced wound area, 8-oxo-dG level (oxidative …

Physical exercise induces inflammatory and oxidative markers production in the skeletal muscle and this process is under the control of both endogenous and exogenous modulators. Recently, molecular hydrogen (H2) has been described as a therapeutic gas able to reduced oxidative stress in a number of conditions. However, nothing is known about its putative role in the inflammatory and oxidative status …

Dehydration is one of the intrauterine abnormalities that could lead to fetal growth retardation and to increase the risk of a variety of adult diseases later in life. This study were to determine the impact of hydrogen-rich water (HRW) supplementation on placental angiotensin II type 1 receptor and placental oxidative stress induced by water restriction. Pregnant Wistar rat were randomly …

It is well known that CD4+CD25+Foxp3+Treg cells play an important role in the development of allergic rhinitis (AR); the defect of cell numbers and functions contribute to AR. Hydrogen has been proven effective in alleviating symptoms of AR. The authors herein aim to verify the protective effects of hydrogen on CD4+CD25+Foxp3+Treg cells in guinea pigs with AR and to explore …

Oxidative stress is generated during the pathophysiology of endometriosis (EMT). Hydrogen (H2) has been demonstrated as a gas antioxidant. The aim of the present study is to evaluate the protective effect of H2 on EMT in rats. Sprague Dawley rats with surgically induced EMT were randomly received the inhalation of 67% H2-33% oxygen (O2) mixture (1 h/d, 4 weeks) immediately …

The inability to successfully adapt to stress produces pathological changes that can lead to depression. Molecular hydrogen has anti-oxidative and anti-inflammatory activities and neuroprotective effects. However, the potential role of molecular hydrogen in stress-related disorders is still poorly understood. The present study aims to investigate the effects of hydrogen gas on resilience to stress in mice. The results showed that …

Medical gas hydrogen (H2) has a special role in airway inflammation; however, the effect of H2 on allergic rhinitis (AR) remains unclear. This study explored the possible roles of H2 on the pathogenesis of AR and observed the influences of H2 on cytokines IL-4 and IL-13. An AR guinea pig model was established by nasal ovalbumin sensitisation. Eighteen guinea pigs …

The present study aimed to investigate the effects of hydrogen-rich saline solution (HRSS) in a rat model of ovarian ischemia-reperfusion injury. Thirty-six female Wistar-albino rats were grouped randomly, into six groups of six rats. The groups were classified as: sham (S), hydrogen (H), torsion (T), torsion/detorsion (TD), hydrogen-torsion (HT), and hydrogen-torsion/detorsion (HTD). Bilateral adnexal torsion was performed for 3h in …
