The aim of this study was to study the possible anti-inflammatory effect of hydrogen-rich saline (H(2) saline) on rat hearts with regional myocardial ischemia and reperfusion (I/R). Sixty-six rats were equally randomized to three groups: sham-operated group, I/R group (control group) and I/R plus H(2) saline treatment group. Myocardial I/R was established by occlusion of the left anterior descending (LAD) …
Amelioration of rat cardiac ischemia injury with inhaled hydrogen
Recent advances in novel medical gases, including hydrogen and carbon monoxide (CO), have demonstrated significant opportunities for therapeutic use. This study was designed to evaluate the effects of inhaled hydrogen or CO, or both, on cold ischemia/reperfusion (I/R) injury of the myocardium. Syngeneic heterotopic heart transplantation was performed in rats after 6 or 18 hours of cold ischemia in Celsior …
The potential cardioprotective effects of hydrogen in irradiated mice
Most ionizing radiation-induced damage is caused by hydroxyl radicals, and the selective reduction of hydroxyl by hydrogen in vitro has been demonstrated previously. Irradiation of the heart can cause chronic cardiac disease. This study was designed to test the hypothesis that hydrogen-rich water (pure water saturated with molecular hydrogen), which is easy to use, induces cardioprotection against ionizing irradiation injury …
Hydrogen-rich saline protects myocardium against ischemia/reperfusion injury
Protective effect of hydrogen (H(2)) gas on cardiac ischemia-reperfusion (I/R) injury has been demonstrated previously. This study was designed to test the hypothesis that hydrogen-rich saline (saline saturated with molecular hydrogen), which is easy to use, induces cardioprotection against ischemia (30 min) and reperfusion (24 h) injury in rats. Adult male Sprague-Dawley rats underwent 30-min occlusion of the left anterior …
Consumption of hydrogen water prevents atherosclerosis in apolipoprotein E knockout mice
Oxidative stress is implicated in atherogenesis; however most clinical trials with dietary antioxidants failed to show marked success in preventing atherosclerotic diseases. Authors have found that hydrogen (dihydrogen; H(2)) acts as an effective antioxidant to reduce oxidative stress [I. Ohsawa, M. Ishikawa, K. Takahashi, M. Watanabe, K. Nishimaki, K. Yamagata, K. Katsura, Y. Katayama, S, Asoh, S. Ohta, Hydrogen acts …
Hydrogen gas reduces infarct size in the rat model of myocardial ischemia
Inhalation of hydrogen (H(2)) gas has been demonstrated to limit the infarct volume of brain and liver by reducing ischemia-reperfusion injury in rodents. When translated into clinical practice, this therapy must be most frequently applied in the treatment of patients with acute myocardial infarction, since angioplastic recanalization of infarct-related occluded coronary artery is routinely performed. Therefore, we investigate whether H(2) …
