Effect of Taklisodok-um and Hwangryunhaedok-tang on Atopic Dermatitis

Abstract

Objective:This Experimental study was done to investigate the Effect of Taklisodok-um and Hwangryunhaedok-tang(TH) on Atopic Dermatitis. Methods : We assessed effects of TH on the IgE, IL-4, IL-5, IL-6, IgM, IgG1, IFN-γ in vivo, on the IL-4, IL-5, CCR3 in the skin tissues of ear and dorsum with NC/Nga mice. And we assessed effects of TH on the COX-2, IL-1β, TNF-α, IL-6 with RAW 264.7 cell. ResultsandConclusion: 1.IgE, IL-4, IL-5, IL-6, IgM, IgGl levels in the serum of TH treated NC/Nga mouse group were decreased compared to the untreated control mice. IFN-r showed a increase in the experimental group compared to the untreated control group. The spleen weight of TH treated NC/Nga mice was decreased compared to the untreated control group. 2.mRNA expression levels of IL-4, IL-5 and CCR3 in the skin tissues of TH treated NC/Nga mice were decreased, and expression levels of IL-6 in the skin tissues of TH treated NC/Nga mice were decreased compared to the untreated control group. IFN-γ mRNA expression levels were increased compared to the untreated control group. 3.Judged from that IL-1β, TNF-α, IL-6 express of gene, effect of inflammatory Cytokines revelation were decreased compared to the untreated control group. 4.Depend on the strength of TH, inflammatory RAW 264.7 in the serum of TH were inhibited compared to the untreated control serum that leaded a COX-2 activity model. 5.Histological observation of the ear and skin tissues showed that the extents of inflammation and infiltrated immune cells in the epidermis and dermis of TH treated NC/Nga mice were highly reduced compared to the untreated control group.Keywords:Taklisodok-um(Tuōlǐxiāodu-yǐn), Hwangryunhaedok-tang(Huanglianjiědu-tāng), Anti-allergy, Anti- inflammatory, Atopic dermatitis
