Changes of 8-OHdG expressions in the biopsied gastric tissue (A) Change of 8-OHdG in placebo control group [48]. Though H. pylori was successfully eradication with triple therapy, biopsied tissue obtained after 10weeks of H. pylori eradication showed the remaining of gastric inflammatory activities. Therefore, 8-OHdG expressions were decreased in a scant level compared to the levels before eradication. This finding suggest that simple removal of bug was not so efficient in attenuating 8-OHdG levels, biomarker of oxidative stress related to H. pylori infection (B) Change of 8-OHdG in Korea red ginseng treated group. In contrast to placebo group, the levels of 8-OHdG expression were significantly decreased in case, who were administered with supplementary red ginseng after eradication regimen, in spite of failure in eradication. These finding necessitates the supplementation of Korea red ginseng to tackle the oxidative stress imposed by H. pylori infection.
