Abstract

Objectives

The purpose of this study is to examine the effect of water and fermentation extracts of KMS (Kami-Mihudeongsikjang-tang) on AD (atopic dermatitis). Additionally, by applying the fermentation extracts of KMS at the first sensitization and latency period, I investgated whether it could prevent AD.

Methods

In this study, to test the effect and preventive efficacy of KMSs on AD. DNCB-induced BALB/c mice of AD model was used. Through histological observation, epidermis and dermis thickness, the infiltration of eoshiphils and mast cells in epidermis and dermis were examined. We measured the serum level of IgE and IL-6, TNF-alpha, and the expressions of NF-κB and MAPK protein. In order to examine the effect of KMSs on keratinocyte, HaCaT cells were treated TNF-alpha and IFN-gamma to induce an inflammatory response. The KMSs were applied at various concentration in the experimental group. We investigated TARC expression.

Results

The treatment groups were reduced epidermis and dermis thickness, inhibited the infiltration of eosinophils and mast cells, reduced the serum level of IL-6. Moreover, sfKMS group reduced serum level of TNF-alpha, inhibited the protein expressions of NF-κB and the phosphoryllation of ERK, JNK and p38. Especially sfKMS-pre group were reduced the serum level of IgE, show significant inhibition on the protein expression of NF-κB and the phosphoryllation of ERK, JNK and p38. In the experiment on HaCaT cells, sfKMS group were reduced expression of TARC.

Conclusions

These result suggest that wKMS and sfKMS was effective in the treament on AD, and sfKMS would prevent AD.
