Electrolyzed-reduced water (ERW) produced by electrolyzing water in cathode side has the ability to scavenge reactive oxygen species (ROS). Here, we investigated the effect of ERW on oxidative stress-induced neural cell death by glutamate. When cell viability assay was performed using primary rat cerebral cortical culture as neural model, ERW suppressed neural cell death by glutamate. Furthermore, ...
We evaluated the properties and real existence of an electrolyzed-reduced water, which we prepared, and three commercially purchased water goods, that are advertised to have antioxidant activities by the action of 'active hydrogen,' on the basis of the results of examinations for inhibitory effects on the oxidative reactions of biomolecules, quantitative analyses of the minerals, and the ESR ...
We examined the suppressive effect on lipid peroxidation of electrolyzed reduced water (ERW), which exhibited reactive oxygen species (ROS)-scavenging activity in vitro and in cultured cells. The oxidation of linoleic acid by 2, 2’-azobis (2-amidinopropane) hydrochloride (AAPH) was suppressed by ERW in vitro. ERW also suppressed the lipid peroxidation in cell membrane of mouse lymphoblast YAC-1 ...
The purpose of this study was to determine the efficacy and the tolerability of the Charme™ system, a hand-held device that electrolyzes a water-based sodium chloride solution and delivers electrolyzed oxidized water (EOW) to the skin, in the treatment of mild to moderate acne. A total of 31 patients with mild to moderate acne vulgaris were enrolled in this 8-week, open-label, split-face pilot ...
We reported that reduced water produced by electrolysis enhanced the antioxidant effects of proton donors such as ascorbic acid (AsA) in a previous paper. We also demonstrated that reduced water produced by electrolysis of 2 mM NaCl solutions did not show antioxidant effects by itself. We reasoned that the enhancement of antioxidant effects may be due to the increase of the ionic product of water ...
A new type of electrolyzed hydrogen-saturated (EHS) water was produced using a water-electrolyzing device equipped with a special cation exchanger. Use of the EHS water for drinking in a feeding test with rats elicited an antioxidative effect. After intraperitoneal injection of 2,2-azobis-amidinopropane dihydrochloride, urinary secretion of 8-hydroxydeoxyguanosine and hepatic formation of ...
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 ...
Recent studies have demonstrated that reactive oxygen species9ROS9and the resulting oxidative stress play an important role in apoptosis. Apoptosis is implicated in pathophysiology of diabetes mellitus. Antioxidants can block or delay apoptosis. We have demonstrated that reduced water (RW) such as hydrogen-rich electrolysed-reduced water (ERW) and natural reduced waters (NRW) like Hita Tenryosui ...
In the two-stage cell transformation theory, cancer cells first receive initiation, which is mainly caused by DNA damage, and then promotion, which enhances transformation. Murine Balb/c 3T3 cells are widely used for transformation experiments because they lose contact inhibition ability when transformed. Electrolyzed reduced water (ERW), which is produced near a cathode during electrolysis of ...
According to the two-stage cell transformation theory, cancer cells first receive initiation, which is mainly caused by DNA damage and then promotion, which enhance transformation. Since murine Balb/c 3T3 cells lose contact inhibition by cell transformation, the cells have been widely used for transformation experiments. Electrolyzed reduced water (ERW) is a health beneficial alkaline drinking ...
The purpose of this study was to evaluate the cleaning effect of root canal walls using strong acid electrolytic water (SAEW) as a root canal irrigant, and to investigate the influence of SAEW on the root canal dentin by micro-hardness test. Forty-three single-rooted, single-canaled teeth were instrumented using standard step-back technique with K-files. Irrigation was performed using distilled ...
The generation of reactive oxygen species is thought to cause extensive oxidative damage to various biomolecules such as DNA, RNA, and protein. In this study, the preventive, suppressive, and protective effects of in vitro supplementation with electrolyzed-reduced water on H2O2-induced DNA damage in human lymphocytes were examined using a comet assay. Pretreatment, cotreatment, and posttreatment ...
This study investigated the antibacterial effect of electrolyzed water on oral bacteria both in vitro and in vivo. Tap water was electrolyzed in a water vessel using platinum cell technology. The electrolyzed tap water (called Puri-water) was put in contact with five major periodontopathogens or toothbrushes contaminated with these bacteria for 30 sec. In addition, Puri-water was used as a ...
Mineral-induced alkaline-reduced water (MRW) is generated by the chemical reaction of water with alkaline earth metals and characterized by high pH and low oxidation-reduction potential. As ROS are believed to have a role in the pathogenesis of obesity, we attempted to determine the effect of MRW on obesity in Sprague-Dawley (SD) rats fed on a high-fat diet. The body weight of the MRW group was ...
Oxidative stress is produced under diabetic conditions and is likely involved in progression of pancreatic beta-cell dysfunction found in diabetes. Both an increase in reactive oxygen free radical species (ROS) and a decrease in the antioxidant defense mechanism lead to the increase in oxidative stress in diabetes. Electrolyzed reduced water (ERW) with ROS scavenging ability may have a potential ...
Chronic hemodialysis (HD) patients increase erythrocyte susceptibility to hemolysis and impair cell survival. We explored whether electrolyte-reduced water (ERW) could palliate HD-evoked erythrocyte impairment and anemia. Forty-three patients undergoing chronic HD were enrolled and received ERW administration for 6 month. We evaluated oxidative stress in blood and plasma, erythrocyte methemoglobin ...
Alkalin-reduced water (ARW) is known to exert several anti-cancer effects, as well as to scavenge reactive oxygen species (ROS) and reduce blood-glucose levels. This study was performed in order to determine the effects of ARW on the control of spontaneous diabetes in Otsuka Long-Evans Tokushima Fatty (OLETF) rats. We assigned 16 male OLETF rats (4 wk) to two groups: an experimental group, which ...
The study examined changes in the relevant tests parameters of 320 diabetes patients (176 female, 144 male) drinking natural reduced water from the 'Nordenau Spring' in Nordenau, Germany as well as the correlation of these changes with the fluctuation of the reactive oxygen species concentration in their blood. The average age of the test persons was 71.8 years old and the daily consumption of ...
The in vivo effects of drinking a water product, which had been confirmed to have antioxidant activi- ties in vitro, were preliminarily studied by monitoring the blood concentrations of oxidative stress marker substances in the two group subjects who ingested the same quantity of the water product and a tap water solution during the same time. The results indicated that hydrogen gas and reductive ...
Acute oxidative stress induced by ischemia-reperfusion or inflammation causes serious damage to tissues, and persistent oxidative stress is accepted as one of the causes of many common diseases including cancer. We show here that hydrogen (H(2)) has potential as an antioxidant in preventive and therapeutic applications. We induced acute oxidative stress in cultured cells by three independent ...
The analysis using the DBNBS reduction method and the DCFH-DA intracellular reactive oxygen species (ROS) determination method revealed that ERW and diseases-improvable natural waters such as Nordenau water in Germany and Hita water in Japan were all reduced waters (RWs) which could function as active hydrogen donors and intracellular ROS scavengers. RWs suppressed the activity of protein tyrosine ...
Oxidative stress is produced under diabetic conditions and involved in progression of pancreatic beta-cell dysfunction. Both an increase in reactive oxygen free radical species (ROS) and a decrease in the antioxidant defense mechanism lead to the increase in oxidative stress in diabetes. Electrolyzed reduced water (ERW) with ROS scavenging ability may have a potential effect on diabetic animals, a ...
Electrolyzed water (EW) generated on the cathode side reportedly displays anti-oxidative properties, and application of EW to hemodialysis (HD) systems supposedly suppresses oxidative markers in patients on HD. However, most of the chemical properties and biological effects of such solutions remain unclear. This study aimed to examine those issues to clarify the scientific background for the ...
Vascular endothelial growth factor (VEGF) is a key mediator of tumor angiogenesis. Tumor cells are exposed to higher oxidative stress compared to normal cells. Numerous reports have demonstrated that the intracellular redox (oxidation/reduction) state is closely associated with the pattern of VEGF expression. Electrolyzed reduced water (ERW) produced near the cathode during the electrolysis of ...
