Electrochemically reduced water exerts superior reactive oxygen species scavenging activity in HT1080 cells than the equivalent level of hydrogen-dissolved water

Result of DPPH assay and ORAC assay of H2-dissolved water and ERW.

A. DPPH assay of sample water. B. ORAC assay of sample water. MQ, MilliQ water; FW, filtered pure water; +Mixed gas, H2, O2 and N2 mixed gas was bubbled to obtain DO and DH concentrations equal to those of LV4. The pH was adjusted using sodium hydrate. LV1 and LV4, ERW at electrolysis levels of 1 and 4, respectively. H2Sat, hydrogen saturated water. * indicates p values of < 0.01 when compared with the value for MQ.
