Hydrogen-rich saline provides a high concentration of hydrogen, which selectively reduces levels of hydroxyl radicals and alleviates acute oxidative stress in many models. Authors investigated the protective effects and mechanisms of three different hydrogen-rich liquid resuscitation preparations on lung injury-induced uncontrolled-hemorrhagic shock (UHS) in rats. A UHS rat model was prepared using the method of Capone et al. of arterial bleeding …
Hydrogen-rich saline exerts protective effects in acute lung injury induced by smoke inhalation
The present study explored the protective effects of hydrogen-rich saline on rats with smoke inhalation injury. 36 healthy male Sprague-Dawley rats were randomly divided into 3 groups (n = 12 per group): sham group (S), inhalation injury plus normal saline treatment group (I+NS), and inhalation injury plus hydrogen-rich saline treatment group (I+HS). 30 min after injury, normal saline and hydrogen-rich saline …
Hydrogen-rich saline ameliorates lung injury and puncture-induced sepsis
Although hydrogen has been proved to be a novel therapeutic medical gas in several lung injury animal models, to our knowledge, it has not been tested yet in acute lung injury (ALI) induced by cecal ligation and puncture (CLP). This study was to investigate the hypothesis that hydrogen could ameliorate CLP-induced lung injury in rats. Our experiments exhibited that gas …
Combined early fluid resuscitation and hydrogen inhalation attenuates lung and intestine injury
This study evaluated the effects of combined early fluid resuscitation and hydrogen inhalation on septic shock-induced lung and intestine injuries. Wistar male rats were randomly divided into four groups: control group (Group A, n = 15); septic shock group (Group B, n = 15); early fluid resuscitation-treated septic shock group (Group C, n = 15); and early fluid resuscitation and …
Hydrogen exerts protective effects on lung grafts
The process of brain death induces acute lung injury in donors and aggravates ischemia-reperfusion injury (IRI) in grafts. Hydrogen, a new anti-oxidant, attenuates IRI in several organ transplant models. Authors examined whether 2% inhaled hydrogen would show favorable effects on lung grafts from brain-dead donor rats. Brain-dead donor rats inhaled mixed gases with either 50% oxygen and 50% nitrogen or …
Hydrogen inhalation ameliorates acute lung injury
Acute lung injury (ALI) is a serious illness, the incidence and mortality of which are very high. Free radicals, such as hydroxyl radicals (OH) and peroxynitrite (ONOO(-)), are considered to be the final causative molecules in the pathogenesis of ALI. Hydrogen, a new antioxidant, can selectively reduce OH and ONOO(-). In the present study, we investigated the hypothesis that hydrogen …
Attenuation of cigarette smoke-induced airway mucus production by hydrogen-rich saline
Over-production of mucus is an important pathophysiological feature in chronic airway disease such as chronic obstructive pulmonary disease (COPD) and asthma. Cigarette smoking (CS) is the leading cause of COPD. Oxidative stress plays a key role in CS-induced airway abnormal mucus production. Hydrogen protected cells and tissues against oxidative damage by scavenging hydroxyl radicals. In the present study authors investigated …
Hydrogen reduces airway remodeling in asthma
Recent studies suggest that hydrogen has great therapeutic and prophylactic potential against organ injury caused by oxidative stress and inflammation. Here authors investigated the effect of hydrogen-rich saline on airway inflammation and remodeling in a murine model of asthma. Asthma was induced by ovalbumin (OVA) sensitization and challenge. Then mice were treated with normal saline or hydrogen-rich saline at low …
Hydrogen-rich saline attenuates lung ischemia-reperfusion injury in rabbits
Hydrogen gas, an antioxidant agent, was found to protect against cerebral and myocardial ischemia-reperfusion (I/R) injury. In the present study, authors investigated the effect of hydrogen-rich saline (HRS) on the I/R-induced lung injury. Left lung of male New Zealand White rabbits rendered normothermic ischemia for 60 min and reperfused for up to 240 min. Treated animals received intraperitoneal injection of …
Protective effects of hydrogen-rich saline on pulmonary hypertension
Hydrogen-rich saline has been reported to have antioxidant and anti-inflammatory effects and effectively protect against organ damage. Oxidative stress and inflammation contribute to the pathogenesis and/or development of pulmonary hypertension. In this study, we investigated the effects of hydrogen-rich saline on the prevention of pulmonary hypertension induced by monocrotaline in a rat model. In male Sprague-Dawley rats, pulmonary hypertension was …
