Abstract

Atopic dermatitis induced NC/Nga mice were used to investigate the efficacy of HYT on the recovery of dermatitic symptoms by how HYT influenced the immune related factors. The results are as below: 1. Compared to the control, HYT treated group showed recovery of atopic dermatitis by the naked eye observation, and significant reduction of dermatits index was observed after 14 weeks. 2. HYT treated group showed significant decrease of the ratio of CCR3+, B220+/IgE+, and Gr-1+/CD11b+ immune cells in dorsal skin by 40.5%, 34.2%, and 48.1%, respectively. 3. HYT treated group showed increase in the ratio of CD19+ immune cells within PBMC by 10.8%, as well as decrease in CD3+, CD3+/CD69+, NKT+ ratios by 5.3%, 35.2%, and 44.9%, respectively. 4. HYT treated group showed increase in the expression of IFN-γ in serum by 589.3%, whereas the expression of IL-4, IL-5, IL-6, IL-13, TNF-α, MCP-1 and RANTES were decreased by 31.4%, 82.1%, 97.1%, 39.5%, 83.7%, 26.1%, 48.6%, respectively. A 47.2% decrease in IgE expression was also observed. The results above strongly supported the improvement of atopic dermatitis by HYT treatment through immune modulation. Further studies on the synergistic effect of each ingredients of HYT and therapeutic effects according to the dosage of each ingredient should be followed for clinical applications. This work was (partly) supported by the RIC program of MKE(Ministry of Knowledge Economy) in Daejeon University.
