For instance, Xie, Y.J. et al. demonstrated that Dioscoreae Rhizoma significantly increased the levels of antioxidant enzymes such as GPx, CAT, and SOD, while concurrently reducing malondialdehyde (MDA) levels and inhibiting nuclear factor (NF)-κB phosphorylation in ethanol-induced gastric ulcers (48). This evidence concerns the gene CAT and gastric ulcer.
