  • This study is about ionic water generator filter Recently, a lot of people feel deep interest in health and drinking water. Evaluation of the stability of oxidation-reduced potential (ORP) using the filter of the alkaline water. This study utilizes the three filter of activated carbon, UF, carbon block in alkaline reduced water equipment. Passing the water to the filter is evaluated that the OPR values are stability in accordance with the change of the volume in the bucket. Alkaline reduced water equipment is a system that has the function of making the water reduction. This system is the values of the human body beneficial minerals and ORP are made in the functional water has a very low value than general water. Which has passed through the filter the water in the water negative ions and positive ions through the electrolytic. After electrolysis, the cathode side by water, including $Ca^+$, $K^+$, $Mg^+$, $Na^+$ water gets Alkaline Reduced Water containing the minerals beneficial to the human body. A positive electrode side is made of the organic materials that have an anion such as chlorine (Cl), phosphorus (P), sulfur(S). This experiment uses the Alkaline Reduced Water to adjust the magnitude of the voltage of the electrolysis in the Alkaline Reduced Water. That is 1st step(pH8) 2nd step (pH8.5) 3th step (pH9), 4th step (pH9.5) in the Alkaline Reduced Water and -1st step (pH6.0), -2nd step (pH5.0) used as the acidic oxidation water. When the water passes through the three filter in this system was evaluated whether the ORP values are changed and stabilized. When about 100 liters of water passing through the filter was confirmed that the ORP values are stability and evaluation.

  • 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 significantly lower than that of the control group in most periods of the examination (P<0.05). Serum level of triglycerides (p<0.05) and fat deposition in the livers of the MRW group were found to have been significantly reduced. This suggests that MRW down-regulates lipid metabolism, thereby suppressing obesity. Possible mechanisms of MRW related to reactive oxygen species were also discussed. Our results suggest that MRW is effective in the alleviation of obesity in SD rats fed on high-fat diet.

  • Electrolyzed reduced water was known as an alkaline solvent than piped water, natural water and mineral water etc. By means of reduction property, electrolyzed reduced water could dissolve a solute than other kinds of water without chemicals. In this study, serpentine dissolution in electrolyzed reduced water was investigated as a novel pre-treatment of serpentine which was a minerals for carbon dioxide sequestration. The elements (Ca, Si, Mg etc.) of serpentine were dissolved rapidly at early in the dissolvation then after some minutes the solubilities of serpentine elements showed stable state without abrupt changes. In spite of serpentine elements dissolution, chemical bondings and crystallographic structure of serpentine were not changed. It was explained that the dissolution mechanism of serpentine occurred from surface in electrolyzed reduced water and bulk structure sustained without collapse.

  • Due to the intermittency of renewable energy sources, a need to store and transport energy will increase. Hydrogen production through water electrolysis will provide an excellent way to supplement the intermittency of renewable energy sources. While alkaline water electrolysis is currently the most mature technology, it has drawbacks of low current density, large footprint, gas crossover, etc. The PEM water electrolysis has potential to replace the alkaline electrolysis. However, expensive catalyst material used in the PEM electrolysis has been the bottleneck of widespread use. In this review, we have reviewed recent efforts to reduce catalyst loading in PEM water electrolysis. In core-shell nanostructures, the precious metal catalyst forms a shell while heteroatoms form a core. In this way, the catalyst loading can be significantly reduced while maintaining the catalytic activity. In another approach, a corrosion-resistant support is utilized, which provides a stable platform to impregnate precious metal catalyst.

  • pH adjustment would be of advantage in improving the water holding capacity of muscle proteins. The objective of this study was to evaluate the addition of fish sarcoplasmic protein (SP) solution, which was adjusted to pH 3.0 or 12.0, neutralized to pH 7.0, and lyophilized to obtain the acid- and alkaline-treated SP samples, on the functional properties of the chicken myofibrillar protein induced by microbial transglutaminase (MTG). The solubility of alkaline-treated SP was higher than that of the acid counterpart; however, those values of the two pH-treated samples were lower than that of normal SP (p<0.05). All SP solutions were mixed with myofibrillar proteins (MP) extracted from chicken breast, and incubated with MTG. The shear stresses of MP with acid- and alkaline-treated SP were higher than that of normal SP. The thermal stability of MP mixture reduced upon adding SP, regardless of the pH treatment. The breaking force of MP gels with acid-treated SP increased more than those of alkaline-treated SP, while normal SP showed the highest value. The MP gel lightness increased, but cooking loss reduced, with the addition of SP. Smooth microstructure of the gel surface was observed. These results indicated that adjusting the pH of SP improved the water holding capacity of chicken myofibrillar proteins induced by MTG.

  • Effects of alkaline reduced water (ARW) on the scavenging of reactive oxygen species (ROS) and diabetes were recently reported. However, no studies have yet been investigated on general drinking effects. In this study, we examined 100 patients hospitalized for senile disease treatment and recuperation. All examines received the ARW for 2 months. WBC level was decreased from $6.34\pm1.9(\times10^9/L)$ to $5.66\pm1.7(\times10^9/L)$. SGPT level was decreased from 27.47$\pm$14 Ut to 23.95$\pm$8.8 U/L. Cholesterol level was increased from 167.9$\pm$32 mg/dl to 176.21$\pm$42 mg/dl within normal range. However, the levels of potassium, adiponectin, SGOT and blood pressure showed no significant difference. The levels of growth hormone and homocysteine and mini-mental state examination also showed no significant difference. We suppose that the slight blood parameter trends indicate an improved physical condition induced by the ARW. Furthermore, we could found no harmful effect of the ARW in this study.

  • Alkaline reduced water (ARW) has been used for drinking widely in several countries of Asia. The safety and clinical effects of ARW has been reported including anti-oxidative effect and intestinal abnormal fermentation. To confirm the effect of ARW on DSS-induced acute inflammatory bowel disease (IBD) mouse model, we observed the length of total large intestine and the histopathological changes after supplying mineral induced-ARW (MARW) for 2 weeks and oral administration of 4% DSS (dextran sulfate sodium). As the result, the length of total large intestine and the disease scores by macro and microscopical access in the ARWsupplied group showed no significant differences compared with those in the control group. This result suggests that the supply of ARW for 2 weeks exerted no effect on amelioration in the DSS-induced acute IBD model. However, in consideration of the effect of ARW on the improvement of intestinal environment and gastrointestinal disease, this result seems that acute IBD animal model is not suitable or the period of ARW supply is not enough to prove the effect of ARW. The ameliorative effect of ARW on the intestinal abnormal fermentation has been confirmed by some researchers, but the precise mechanism also remain unclear. In conclusion, although MARW had no effect on the DSS-induced acute experimental colitis model, further studies on the verification of the effects of ARW by using other intestinal disease model and by long-term supply of ARW will be required. Also, It needs to clear the mechanism of ARW on the intestinal environment.

  • An anatase TiO2 nanotube array (NTA) was fabricated by anodization and successive heat treatments. When the anatase TiO2 NTA was cathodically polarized, its color changed to blue, and it could be used as an electrochemically active anode for an oxygen evolution reaction (OER) in alkaline water electrolysis. The structure of the blue anatase TiO2 NTA was controlled by the anodization conditions and its catalytic activity increased with an increase of the surface area. The activity of the blue anatase TiO2 NTA gradually reduced with the continued OER because of the partial oxidation of Ti3+ to Ti4+. However, an intermittent cathodic regeneration process could significantly slow its reduction rate. The blue anatase TiO2 NTA could be an alternative anode for alkaline water electrolysis.

  • Experiments were performed on mice to investigate the effect of Panax ginseng petroleum ether fraction on the immunotoxicity of lead acetate. Lead acetate was administered in the drinking water and ginseng p-ether fraction was injected intraperitoneally, Mice were sensitized and challenged with sheep red blood cell. Humoral immune responses were evaluated by antibody production and Arthus reaction. Pathotoxicological influences were measured by serum protein, alkaline phosphatase and total cholesterol. The weight of liver, spleen and thymus were measured. Lead acetate exposure significantly decreased hemagglutination titer, hemolysin titer, Arthus reaction, spleen and thymus weight. Ginseng p-ether fraction administration significantly restored or potentiated reduced humoral immune response, spleen and thymus weight. Reduced serum A/G ratio, total cholesterol and alkaline phosphatase activity were restored or increased by ginseng p-ether fraction administration.

  • Balneotherapy has been widely used for the treatment of skin diseases in the world. The purpose of this study was to determine the bath effect of the alkaline reduced spring water with the properties of high pH and low oxidation reduction potential (ORP) on the skin injury induced by ultra violet (UV) irradiation. For this purpose, hairless mice were irradiated with UV-B to cause skin injury, and individually taken a bath in spring water (experimental group) and tap water (control group) once a day for 40 min during 21 days. We observed histological changes of the back skin through macro- and microscopic methods compared to the control group. We found that skin injury of the experimental group was more quickly recovered than that of the control group. Under the light microscope, the experimental group showed that epidermal thickening (p<0.01) and the mast cell activation (p<0.001) were lower compared with the control group, in addition infiltration of inflammatory cells and degranulation of mast cells were less observed. These results suggest that regular bath in the spring water with the properties of high pH and low ORP has a positive effect on the skin injury induced by UV irradiation.
