Abstract

Objective: The aim of this study was to investigative the effects of Gagambojungikgi-tang (GBT), a Korean herbal medicine, on the immune mediators, T cell proliferation and wound healing in the recombinant Sj26 (rSj26) antigen induced atopic dermatitis(AD) model mice.
Methods: GBT is the water extracts prepared from mixture of Ginseng Radix, Astragali Radix, Angelicae gigantis Radix, Atractylodes Rhizoma alba, Aurantii nobilis Pericarpium, Glycyrrhizae Radix, Artemisia iwayomogi Herba, Scutellaria Radix, Lonicera japonica Flos. This is a modified prescription of Bojungikgi-tang, which has been used for the treatment of indigestion, and immunological disease in east-asian countries. GBT was orally administered or externally applied at difference doses. The levels of immune mediators [(IgE, IgG1, prostaglandin E2 (PGE2), Th1/Th2 cytokines], T cell proliferation, and wound healing in the rSj26 or chemical antigen induced AD model BALB/c were investigated.
Results: GBT dose-dependently suppressed the release of TNF-α, IL-1β (Th1 cytokines), IL-4, IL-10
(Th2 cytokines), PGE2 (inflammatory mediators) and T cell proliferation. But GBT increased the production of IFN-γ (Th1 cytokine). Furthermore, A wound healing effect of GBT was similar to external application of dexamethasone.
Conclusions: These results suggest that GBT suppresses the inflammatory mediators and regulates the
Th1/Th2 cytokines, and promotes the wound healing. Therefore, these properties may contribute to the
strong anti-AD effect of GBT.
