Neuroprotective Effect of Hydrogen-Rich Saline against Neurologic Damage and Apoptosis in Early ...

Year Published: 2014

Backgrounds: Early brain injury (EBI) plays a key role in the pathogenesis of subarachnoid hemorrhage (SAH). Neuronal apoptosis is involved in the pathological process of EBI. Hydrogen can inhibit neuronal apoptosis and attenuate EBI following SAH. However, the molecular mechanism underlying hydrogen-mediated anti-apoptotic effects in SAH has not been elucidated. In the present study, we aimed to ...

Hydrogen-rich saline improves survival and neurological outcome after cardiac arrest and ...

Year Published: 2014

Background: Sudden cardiac arrest is a leading cause of death worldwide. Three-fourths of cardiac arrest patients die before hospital discharge or experience significant neurological damage. Hydrogen-rich saline, a portable, easily administered, and safe means of delivering hydrogen gas, can exert organ-protective effects through regulating oxidative stress, inflammation, and apoptosis. We ...

Electrochemically reduced water protects neural cells from oxidative damage

Year Published: 2014

Aging-related neurodegenerative disorders are closely associated with mitochondrial dysfunction and oxidative stresses and their incidence tends to increase with aging. Brain is the most vulnerable to reactive species generated by a higher rate of oxygen consumption and glucose utilization compared to other organs. Electrochemically reduced water (ERW) was demonstrated to scavenge reactive oxygen ...

Molecular hydrogen attenuates neuropathic pain in mice

Year Published: 2014

Neuropathic pain remains intractable and the development of new therapeutic strategies are urgently required. Accumulating evidence indicates that overproduction of oxidative stress is a key event in the pathogenesis of neuropathic pain. However, repeated intra-peritoneal or intrathecal injections of antioxidants are unsuitable for continuous use in therapy. Here we show a novel therapeutic method ...

Year Published: 2014

To evaluate protective effects of inhaled hydrogen gas (H2) on cognitive function in a murine model of sepsis-associated encephalopathy (SAE). A total of 84 male ICR mice, weighing 20-25 g, aged 6-8 weeks, were randomly divided into 4 groups of sham, sham+H2, sepsis and sepsis+H2. Sepsis was established by cecal ligation and puncture (CLP). Mice in sham+H2 and sepsis+H2 groups received 2% H2 ...

Inhalation of hydrogen gas attenuates brain injury in mice with cecal ligation and puncture via ...

Year Published: 2014

During the development of sepsis, the complication in central nervous system (CNS), appearing early and frequently relative to other systems, can obviously increase the mortality of sepsis. Moreover, sepsis survivors also accompany long-term cognitive dysfunction, while the ultimate causes and effective therapeutic strategies of brain injury in sepsis are still not fully clear. We designed this ...

Oral intake of hydrogen-rich water ameliorated chlorpyrifos-induced neurotoxicity in rats

Year Published: 2014

Chronic exposure to low-levels of organophosphate (OP) compounds, such as chlorpyrifos (CPF), induces oxidative stress and could be related to neurological disorders. Hydrogen has been identified as a novel antioxidant which could selectively scavenge hydroxyl radicals. We explore whether intake of hydrogen-rich water (HRW) can protect Wistar rats from CPF-induced neurotoxicity. Rats were gavaged ...

Hydrogen-rich saline controls remifentanil-induced hypernociception and NMDA receptor NR1 subunit ...

Year Published: 2014

Background: Although NMDAR trafficking mediated by GSK-3β involvement in transmission of pronociceptive messages in the spinal cord has been confirmed by our previous studies, whether NMDAR trafficking is implicated in peripheral sensitization remains equivocal. It is demonstrated that inflammation is associated with spinal NMDAR-containing nociceptive neurons activation and the maintenance of ...

Hydrogen-rich saline prevents remifentanil-induced hyperalgesia and inhibits MnSOD nitration via ...

Year Published: 2014

Remifentanil administration may subsequently cause paradoxical hyperalgesia in animals and humans, but mechanisms remain unclear. MnSOD nitration and inactivation caused by generation of reactive oxygen species and activation of NMDA receptors are involved in the induction and maintenance of central neuropathic pain. Hydrogen which selectively removes superoxide has gained much attention in recent ...

Year Published: 2013

Most of the results regarding hydrogen (H2) therapy for acute cerebral ischemia are derived from in vitro studies and animal experiments, with only a few obtained from human trials with a limited number of subjects. Thus, there is a paucity of information regarding both the beneficial therapeutic effects as well as the side effects of H2 on acute cerebral ischemia in humans. We designed a pilot ...
