Effect of Korean Red Ginseng extract (RGE) on Helicobacter pylori-induced mRNA expression of keratinocyte chemoattractant factor (KC), interleukin (IL)-1β, and inducible nitric oxide synthase (iNOS), in gastric mucosal tissues of Mongolian gerbils. Real-time quantitative RT-PCR was performed on reverse-transcribed RNA isolated from gastric mucosa. mRNA level of (A) KC, (B) IL-1β, and (C) iNOS was normalized to β-actin. None, animals without H. pylori infection that were fed the control diet; H. pylori control, animals with H. pylori infection that were fed the control diet; and H. pylori + RGE, animals with H. pylori infection that were fed a diet supplemented with RGE. *p < 0.05 versus none. **p < 0.05 versus H. pylori control.
