Hyperoxic lung injury is a major concern in critically ill patients who receive high concentrations of oxygen to treat lung diseases. Successful abrogation of hyperoxic lung injury would have a huge impact on respiratory and critical care medicine. Hydrogen can be administered as a therapeutic medical gas. We recently demonstrated that inhaled hydrogen reduced transplant-induced lung injury and induced heme …
Hydrogen-rich saline provides protection against hyperoxic lung injury
Hydrogen has been proven to be a novel antioxidant through its selectively reducing of the hydroxyl radical. In this study, we investigated the effects of hydrogen-rich saline on the prevention of acute lung injury induced by hyperoxia (HALI) in rats. Physiologic saline, hydrogen-rich saline, or nitrogen-rich saline was administered through intraperitoneal (i.p.) injection during exposure to hyperoxia (10 mL/Kg), respectively. …
Saturated hydrogen saline protects the lung against oxygen toxicity
Exposure to high oxygen concentrations leads to acute lung injury, including lung tissue and alveolar edema formation, congestion, intra-alveolar hemorrhage, as well as endothelial and epithelial cell apoptosis or necrosis. Several studies have reported that molecular hydrogen is an efficient antioxidant by gaseous rapid diffusion into tissues and cells. Moreover, consumption of water with dissolved molecular hydrogen to a saturated …
