A condition of unbalanced minerals was found in soil and drinking water from three amyotrophic lateral sclerosis (ALS) foci on Guam, in the Kii Peninsula and in West New Guinea with a low concentration of calcium and magnesium coupled with a high concentration of aluminum and manganese. The current epidemiological studies in the Western Pacific including the Kii Peninsula of Japan, have suggested that environmental factors contribute to the pathogenetic process of ALS and parkinsonism-dementia (PD). Six Kii cases with ALS showed higher Ca and lower Mg contents in the central nervous system (CNS) tissues than those of neurologically normal controls. The author subsequently designed an animal study to experimentally ascertain the mineral or metal deposition in CNS tissues under various dietary regimens using rats. The experimental results suggest that unbalanced minerals and/or metals lead to the accumulation not only of Ca, but also Mn, and Al, and diminution of Mg and Zn in CNS tissues and bones of rats and humans on these dietary regimens, with implication for long-term neuronal degeneration and accumulating CNS deficit.

Hypochlorite waters with alkaline pH were prepared by electrolysis of 0.1% sodium chloride solutions with pH6.5 and 12.0 using ceramics / titanium electrode without diaphragm between the anode and the cathode. These solutions and tap water were examined for their effect on scrubber in terms of the removal of stinking and noxious compounds known to be generated from decomposed foods and smoking gas. It turned out that the hypochlorite waters show markedly higher effect than tap water in terms of removing hydrogen sulfide, methanethiol (methylmercaptane), carbon monoxide, and nitrogen monoxide. In addition, the hypochlorite water with pH9.5 was capable of removing formaldehyde gas. The capability of removing ammonia and ethanol was comparable between the hypochlorite water and tap water. The electrolysis without diaphragm between the anode and the cathode is a relatively safe and handy method to prepare the hypochlorite waters with alkaline pH, which may be applicable as cleaning solution for scrubber.

We tested deodorant capability of alkaline (pH11.2) and acidic (pH2.5, av.Cl2 40ppm) electrolyzed waters. Vaporized 12 compounds known as malodorant substances were sprayed with electrolyzed waters in a mixing chamber. Difference in the concentrations of the vapors before and after the treatment was measured to estimate the deodorant capability. As results acidic electrolyzed water showed high deodorant capability to ammonia, trimethylamine, pyridine, propionic acid, butyric acid and valeric acid, whereas alkaline electrolyzed water showed a specific deodorant capability to hydrogen sulfide. Methyl mercaptane, acetaldehyde, ethyl acetate, and methyl isobutyl ketone were resistant to the deodorant capability of both waters.
