Protective effect of hydrogen on osteoradionecrosis

In Animal studies, Other studies by CHESS

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 …

Hydrogen-rich saline ameliorates hippocampal neuron apoptosis

In Animal studies, Nervous system by CHESS

This study aimed to evaluate the potential role of hydrogen in rats after cerebral ischemic/reperfusion (I/R) injury. The experimental samples were composed of sham group, model group of rats that received middle cerebral artery occlusion (MCAO) for 2 hr followed by reperfusion for 24 hr, and the hydrogen saline group treated by hydro¬gen-rich saline (1 ml/kg) after MCAO. Hydrogen sulfide …

Hydrogen-rich solution attenuates coagulation disorders and inflammation

In Animal studies, Inflammation by CHESS

Intestinal ischemia/reperfusion (I/R) injury often causes inflammatory responses and coagulation disorders, which is further promoting the deterioration of the disease. Hydrogen has anti-inflammatory, antioxidative, and antiapoptotic properties against various diseases. However, the effect of hydrogen on coagulation dysfunction after intestinal I/R and the underlying mechanism remains unclear. The purpose of this study was to explore whether hydrogen-rich solution (HRS) could …

Hydrogen-rich saline mitigates cardiac hypertrophy

In Animal studies, Cardiovascular by CHESS

The main aim of this study was to investigate if hydrogen-rich saline (HRS), which has been shown to have antioxidant and anti-inflammatory properties, could mitigate cardiac remodelling and reduce the incidence of atrial fibrillation (AF) in the rat model of cardiac hypertrophy. Pressure overload was induced in rats by abdominal aortic constriction (AAC). The animals were separated into four groups: …

Molecular hydrogen application in stroke

In Review papers by CHESS

Stroke is a major cause of mortality and morbidity worldwide. Effective treatments are limited. Molecular hydrogen is emerging as a novel medical gas with therapeutic potential for various neurological diseases, including stroke. We reviewed the experimental and clinical findings of the effects of molecular hydrogen therapy in stroke patients and models. The underlying neuroprotective mechanisms against stroke pathology were also …

Hydrogen gas as an exotic performance-enhancing agent

In Review papers by CHESS

Hydrogen gas (H2 ) has entered the world of experimental therapeutics approximately four and a half decades ago. Over the years, this simple molecule appears to drive more and more scientific attention perhaps due to a dualism of H2 affirmative features demonstrated in numerous in vitro, animal and human studies on one side, and stillpuzzling mechanism(s) of its biological activity …

Luminal preloading with hydrogen ameliorates intestinal transplantation

In Animal studies, Gut by CHESS

Prolonged intestinal cold storage causes considerable mucosal breakdown, which could bolster bacterial translocation and cause life-threatening infection for the transplant recipient. The intestine has an intraluminal compartment, which could be a target for intervention, but has not yet been fully investigated. Hydrogen gas exerts organ protection and has used been recently in several clinical and basic research studies on topics …

Hydrogen-rich saline restores behavioral deficits

In Animal studies, Nervous system by CHESS

The authors have reported previously that hydrogen-rich saline (HS) plays a neuroprotective role in hypoxia-ischemia (HI) brain damage in newborn mice. However, the mechanisms for this neuroprotection resulting from HS remain unknown. In this study, the authors examined the potential for HS to exert effects upon microglial phagocytosis via involvement of the Akt signaling pathway as one of the neuroprotective …

Hydrogen-rich saline reduces skin tissue injury

In Animal studies, Other studies by CHESS

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 …

Hydrogen in mitigating oxidative-stress-induced radiation injury

In Review papers by CHESS

Uncontrolled production of oxygen and nitrogen radicals results in oxidative and nitrosative stresses that impair cellular functions and have been regarded as causative common denominators of many pathological processes. In this review, we report on the beneficial effects of molecular hydrogen in scavenging radicals in an artificial system of •OH formation. As a proof of principle, we also demonstrate that …
