Recently, we published a study on the antioxidant effects of BuOH fraction in experimental models of gastric ulcer [8]; the study shows that BuOH fraction can protect the gastric mucosa through the enhancement of antioxidant mediators and enzymes, such as GSH, GSH-Px, GSH-Rd, SOD as well as diminishing MPO activity and lipid peroxidation. Here, SOD1 is linked to gastric ulcer.
