In this study, we tested the protective effect of hydrogen-rich saline on the brain in a global cerebral I/R model. Materials and methods: We used a four-vessel occlusion model of global cerebral ischemia (15 min) ...

Protective Effect of Hydrogen Gas Therapy After Germinal Matrix Hemorrhage in Neonatal Rats

Year Published: 2011

Germinal matrix hemorrhage (GMH) is a neurological disease of very low birth weight premature infants leading to post-hemorrhagic hydrocephalus, cerebral palsy, and mental retardation. Hydrogen (H2) is a potent antioxidant shown to selectively reverse cytotoxic oxygen-radical injury in the brain. This study investigated the therapeutic effect of hydrogen gas after neonatal GMH injury. Neonatal ...

Hydrogen Inhalation is Neuroprotective and Improves Functional Outcomes in Mice After Intracerebral ...

Year Published: 2011

Oxidative stress contributes significantly to the development of secondary brain injury after intracerebral hemorrhage (ICH). It has been previously demonstrated that hydrogen gas can decrease oxidative stress by scavenging reactive oxygen species. We hypothesized that hydrogen therapy will reduce brain oxidative stress in mice after ICH and thereby will lead to reduced brain edema and improved ...

Improved brain MRI indices in the acute brain stem infarct sites treated with hydroxyl radical ...

Year Published: 2011

In acute stage of cerebral infarction, MRI indices (rDWI & rADC) deteriorate during the first 3-7 days after the ictus and then gradually normalize in approximately 10 days (pseudonormalization time), although the tissue is already infarcted. Since effective treatments improve these indices significantly and in less than the natural pseudonormalization time, a combined analysis of these changes ...

Hippocampal gene network analysis suggests that coral calcium hydride may reduce accelerated ...

Year Published: 2011

Recent studies strongly support the hypothesis that an antioxidant diet inhibits the pathologic aging process as shown in senescence-accelerated mouse prone 8 (SAM/P-8). In our previous study in coral calcium hydride (CCH), we reported that a diet rich in antioxidants inhibited the pathologic aging process, increased the endogenous antioxidant ability, and contributed to prolonging the lifespan of ...

Hydrogen is neuroprotective and preserves cerebrovascular reactivity in asphyxiated newborn pigs

Year Published: 2010

Hydrogen (H2) has been reported to neutralize toxic reactive oxygen species. Oxidative stress is an important mechanism of neuronal damage after perinatal asphyxia. We examined whether 2.1% H2-supplemented room air (H2-RA) ventilation would preserve cerebrovascular reactivity (CR) and brain morphology after asphyxia/reventilation (A/R) in newborn pigs. Anesthetized, ventilated piglets were ...

Drinking hydrogen water ameliorated cognitive impairment in senescence-accelerated mice

Year Published: 2010

Hydrogen has been reported to have neuron protective effects due to its antioxidant properties, but the effects of hydrogen on cognitive impairment due to senescence-related brain alterations and the underlying mechanisms have not been characterized. In this study, we investigated the efficacies of drinking hydrogen water for prevention of spatial memory decline and age-related brain alterations ...

Year Published: 2010

Traumatic brain injury (TBI) is a leading cause of mortality and disability among the young population. It has been shown that hydrogen gas (H(2)) exerts a therapeutic antioxidant activity by selectively reducing hydroxyl radical (OH, the most cytotoxic ROS). Recently, we have found that H(2) inhalation significantly improved the survival rate and organ damage of septic mice. In the present study, ...

Year Published: 2009

Molecular hydrogen serves as an antioxidant that reduces hydroxyl radicals, but not the other reactive oxygen and nitrogen species. In the past year, molecular hydrogen has been reported to prevent or ameliorate eight diseases in rodents and one in human associated with oxidative stress. In Parkinson's disease, mitochondrial dysfunction and the associated oxidative stress are major causes of ...

Hydrogen gas is ineffective in moderate and severe neonatal hypoxia-ischemia rat models

Year Published: 2009

Hydrogen gas (H(2)) has been shown to ameliorate brain injury in experimental adult rat focal ischemia and in a mild neonatal hypoxia-ischemia (HI, 90 min hypoxia) rat model. In this study we tested H(2) in moderate (120 min hypoxia) and severe (150 min hypoxia) neonatal HI rat models. We hypothesized that H(2) would improve outcomes after neonatal HI by scavenging free radicals. Two hundred (200) ...

Year Published: 2009

We have reported that hydrogen (H(2)) acts as an efficient antioxidant by gaseous rapid diffusion. When water saturated with hydrogen (hydrogen water) was placed into the stomach of a rat, hydrogen was detected at several microM level in blood. Because hydrogen gas is unsuitable for continuous consumption, we investigated using mice whether drinking hydrogen water ad libitum, instead of inhaling ...

We have proposed an active hydrogen reduced water theory that active hydrogen produced by electrolysis of water is stabilized in the form of hydrogenated metal nanocolloids in electrolyzed reduced water (ERW) and scavenges intracellular reactive oxygen species (ROS). Because various brain diseases are caused by oxygen stress, we examined the effect of ERW on oxidative stress-induced apoptois of ...
