<P>PROBLEM TO BE SOLVED: To provide electrolytic water containing dissolved hydrogen which can prevent or suppress DNA lesion. <P>SOLUTION: Pure water is obtained from tap water, and NaCl is added to the pure water. Electric conductivity of the solution is adjusted to at least 100 μS/cm. The solution is electrolyzed, and produced cathodic water is taken out and neutralized. The cathodic water contains dissolved hydrogen (H<SP>+</SP>, H free radical, H<SB>2</SB>) of at least 0.1 ppm, and the dissolved hydrogen prevents or suppresses DNA lesion. <P>COPYRIGHT: (C)2003,JPO |
