Table 2 Correlation between inhibition effects and hydrogen concentrations in pH 8.5 electrolyzed water

From: Dose-dependent inhibition of gastric injury by hydrogen in alkaline electrolyzed drinking water

Group Erosion MPO MDA 8-OHdG
C: H2(6.8 μg/d/kg) 2.1% 1.6% 32.6% −2.3%
D: H2(20.1 μg/d/kg) 13.6% 36.8% 36.8% 41.9%
E: H2(80.6 μg/d/kg) 38.6% 77.3% 61.9% 41.4%
Pearson coefficient 0.990 0.952 0.999 0.633
  1. Mucosal protective effect at each hydrogen concentration was calculated by (damage level in group F – damage level in group C or D or E)/(damage level in group F - damage level in group G).
  2. In serum, since the gastric damage did not affect serum 8-OHdG level, the protective effect was calculated by (damage level in group F – damage level in group C or D or E)/damage level in group F.
