MHID-5889693PMID: 257075802015Molecular and Cellular Biochemistry

Sayaka Sobue, Kazuaki Yamai, Mikako Ito, Kinji Ohno, Masafumi Ito, Takashi Iwamoto, et al.

Molecular hydrogen (H2) is an agent with po- tential applications in oxidative stress-related and/or in- flammatory disorders. H2 is usually administered by inhaling H2-containing air (HCA) or by oral intake of H2- rich water (HRW). Despite mounting evidence, the mole- cular mechanism underlying the therapeutic effects and the optimal method of H2 administration remain unclear. Here, we investigate

ONOOH does not react with H2: Potential beneficial effects of H2 as an antioxidant by selective reaction with hydroxyl radicals and peroxynitrite

MHID-6682168PMID: 250864382014Free Radical Biology and Medicine

Jelle Penders, Reinhard Kissner, Willem H. Koppenol

H2 has been suggested to act as an antioxidant when administered just before the reperfusion phase of induced oxidative stress. These effects have been reported, for example, for the heart, brain, and liver. It is hypothesized that this beneficial effect may be due to selective scavenging of HO⋅ and ONOOH by H2. The reaction of H2 with HO⋅ has been studied by pulse radiolysis in the past and is too

MHID-0477754PMID: 247690812014Pharmacology & Therapeutics

Shigeo Ohta

Molecular hydrogen (H2) has been accepted to be an inert and nonfunctional molecule in our body. We have turned this concept by demonstrating that H2 reacts with strong oxidants such as hydroxyl radical in cells, and proposed its potential for preventive and therapeutic applications. H2 has a number of advantages exhibiting extensive effects: H2 rapidly diffuses into tissues and cells, and it is m

Mami Noda, Kyota Fujita, Ikuroh Ohsawa, Masafumi Ito, Kinji Ohno

Molecular hydrogen (H2) has been reported to be effective for a variety of disorders and its effect has been ascribed to a selective scavenge of hydroxyl radicals (•OH) at the beginning. Consumption of H2 was either by inhalation, drinking H2-containing water (H2 water), or infusion of H2-containing saline. Among various disorders, animal model of ischemic injury and Parkinson’s disease showed sig

A new medical gas, molecular hydrogen (H2), has been reported to be effective for a variety of disorders and clinical trials have shown promising results. Though the precise mechanism is still unknown, it is obvious that H2 has multiple effects.

Masanori Kawaguchi, Yasushi Satoh, Yukiko Otsubo, Tomiei Kazama

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

Studies on molecular hydrogen have evolved tremendously from its humble beginnings and have continued to change throughout the years. Hydrogen is extremely unique since it has the capability to act at the cellular level. Hydrogen is qualified to cross the blood brain barrier, to enter the mitochondria, and even has the ability to translocate to the nucleus under certain conditions. Once in these i
