Background: Molecular hydrogen (H2) as a new medical gas has an anti-inflammatory effect. In the present study, we investigated whether heme oxygenase-1 (HO-1) contributes to the anti-inflammatory effect of H2 in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages.
Methods: RAW 264.7 macrophages were stimulated by LPS (1 mg/mL) with presence or absence of different concentrations of H2. Cell

Background: Recent studies show that molecular hydrogen (dihydrogen, H2) has potential as an effective and safe radioprotective agent through reducing oxidative stress. The aim of this study was to investigate whether H2 is able to protect spermatogenesis and hematopoiesis from radiation-induced injuries.

Background: Radiation often causes depletion of immunocytes in tissues and blood, which results in immuno suppression. Molecular hydrogen (H2) has been shown in recent studies to have potential as a safe and effective radioprotective agent through scavenging free radicals. This study was designed to test the hypothesis that H2 could protect immunocytes from ionizing radiation (IR).

Background—We previously demonstrated that donor treatment with inhaled hydrogen protects lung grafts from cold ischemia/reperfusion (I/R) injury during lung transplantation. To elucidate the mechanisms underlying hydrogen’s protective effects, we conducted a gene array analysis to identify changes in gene expression associated with hydrogen treatment.
Methods—Donor rats were exposed to mechanica

Effects of molecular hydrogen on various diseases have been documented for 63 disease models and human diseases in the past four and a half years. Most studies have been performed on rodents including two models of Parkinson’s disease and three models of Alzheimer’s disease. Prominent effects are observed especially in oxidative stress-mediated diseases including neonatal cerebral hypoxia; Parkinson

Acute lung injury (ALI) is still a leading cause of morbidity and mortality in critically ill patients. Recently, our and other studies have found that hydrogen gas (H2) treatment can ameliorate the lung injury induced by sepsis, ventilator, hyperoxia, and ischemia-reperfusion. However, the molecular mechanisms by which H2 ameliorates lung injury remain unclear. In the current study, we investigat

Background: Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by the destruction of bone and cartilage. Although its etiology is unknown, the hydroxyl radical has been suggested to be involved in the pathogenesis of RA. Recently, molecular hydrogen (H2) was demonstrated to be a selective scavenger for the hydroxyl radical. Also, the method to prepare water containing extrem

Ionizing radiation (IR) is a well-known carcinogen, however the mechanism of radiation in- duced thymic lymphoma is not well known. Moreover, an easy and effective method to protect mice from radiation induced thymic lymphoma is still unknown.

Purpose: Cisplatin is a widely used anti-cancer drug in the treatment of a wide range of tumors; however, its application is limited by nephrotoxicity, which is affected by oxidative stress. We have reported that molecular hydrogen (H(2)) acts as an efficient antioxidant (Ohsawa et al. in Nat Med 13:688-694, 2007). Here we show that hydrogen efficiently mitigates the side effects of cisplatin by r

Molecular hydrogen reacts with the hydroxyl radical, a highly cytotoxic species produced in inflamed tissues. It has been suggested therefore to use gaseous hydrogen in a new anti-inflammatory strategy. We tested this idea, with the aid of the equipment and skills of COMEX SA in Marseille, a group who experiments with oxygen–hydrogen breathing mixtures for professional deep-sea diving.
