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.

Osteoporosis is a condition characterized by low bone mass and increased bone fragility. It has become a major problem of senior citizens. The purpose of this study is to experiment the effect of water extract of Forsythiae Fructus (wFF) on osteoclast differentiation; and the other purpose is to examine the effect of wFF on osteoporosis in ovariectomized rat.
Objectives : The purpose of this study is to examine the effects of external application of HC001 on atopic dermatitis. HC001, newly composed herbal medicine combinations contains 9 medicinal herbs which are known to have anti-inflammatory and anti-allergic effects. We investigated the anti-inflammatory effects of HC001 on atopic dermatitis-like skin lesions in mice. Methods : Seven-week-old BALB/c mice were sensitized with DNCB to develop atopic dermatitis. Animals were divide into three group: Normal, DNCB (Negative control group), HC001 (Experimental group, treated with DNCB and HC001). Skin sections were stained with H&E to measure the thicknesses of the epidermis and dermis, respectively. The expression of NF- protein was measured by western blotting analysis in skin lesion. Results : Topical HC001 treatment significantly restored the skin thickening and hyperplasia of the epidermis and dermis compared with DNCB-sensitized group in histopathological analyse. In addition, HC001 inhibited the expression of NF- protein increased in DNCB-induced atopic dermatitis-like skin lesions in mice. Conclusions : These results suggest that HC001 may be useful as an external application agent for atopic dermatitis based on reductions of various inflammatory responses.
Osteoporosis is a common disease in adults with prevalence rate of more than 40%, and occurs more to female than to male. The purpose of this study is to identify the effect of Bia-hwan (Féiér-wán) on the osteoporosis of ovariectomized rats.
