The aim of this study was to evaluate if a composition of herb extracts, PLX-PLS was effective to treat atopic dermatitis (AD) in mice. SPZZC is a composition of herb extracts containing the roots of Scopolia parviflora and Paeonia lactiflora, the herb of Zizania caudiflora, the fruit of Ziziphus jujuba and the leaf of Chinese arborvitae. AD in BALB/c mouse was induced by patching ovoalbumin on the backside, while it in NC/Nga mouse was induced by repeated application of 1-chloro 2,4-dinitrobenzene (DNCB). Mice were topically treated with SPZZC or Domohorn ointment on the backside for 2 weeks (BALB/c) or 1 week (NC/Nga). Scratching behavior, clinical skin severity and the levels of WBC, neutrophil, eosinophil and total serum IgE were measured. After AD induction, scores of scratching behavior and clinical skin severity and the levels of WBC, neutrophil, eosinophil and total serum IgE were increased. Treatment with SPZZC significantly decreased scores of scratching behavior and clinical skin severity in a dose dependent manner in NC/Nga and BALB/c mice. Treatment with SPZZC 2% significantly decreased also the levels of WBC, neutrophil, eosinophil and total serum IgE. Especially, treatment of SPZZC 2% reduced more rapidly score of clinical skin severity than clobetasol cream. These results suggest that the SPZZC may be an alternative substance for the management of AD.

Inducible nitric oxide synthase (iNOS) are important inflammation enzyme and severe up-nitric oxide (NO) production by this enzyme has been intricate with pathogenesis of atopy dermatitis. The present study was designed in order to determine whether Cheonggi-san could inhibit atopy dermatitis through modulation of iNOS mRNA expression and NO production. We found that iNOS mRNA expression and NO production in RAW 264.7 macrophages stimulated with lipopolysaccharide dose-dependantly decreased by Cheonggi-san extract treatment (0.5 - 2.0 mg/ml). The distribution of iNOS positive reacted cell in NC/Nga mice with atopy dermatitis were decreased by Cheonggi-san extract treatment (2.5 ml/kg/day) and apoptosis were increased. These data likely indicate that Cheonggi-san may act as inflammatory regulator for atopy dermatitis and may be possible to develop useful agent for chemoprevention of NO intricate inflammatory diseases.

Inducible nitric oxide synthase (iNOS) are important inflammation enzyme and severe up-nitric oxide (NO) production by this enzyme has been intricate with pathogenesis of atopy dermatitis. The present study was designed in order to determine whether Lonicera japonica could inhibit atopy dermatitis through modulation of iNOS by NF-${\kappa}B$ suppression. We found that IKK mRNA and iNOS mRNA expression in RAW 264.7 macrophages stimulated with lipopolysaccharide dose-dependantly decreased by Lonicera japonica (0.4 - 1.0 mg/$m{\ell}$) and NO production decreased. The distribution of NF-${\kappa}B$ p65 and iNOS positive reacted cell in NC/Nga mice with atopy dermatitis were decreased by Lonicera japonica (45 mg/kg/day) and apoptosis were increased. These data likely indicate that Lonicera japonica may act as inflammatory regulator for atopy dermatitis through iNOS modulation by NF-${\kappa}B$B suppression and may be possible to develop useful agent for chemoprevention of NO intricate inflammatory diseases.

Objectives : Atopic dermatitis(AD) is a chronic recurrent skin disease which usually developed in infancy or childhood. AD often repeat improvement and relapse. The cause of AD is so indefinite that many methods of therapies(moisturizer, steroid ointment, antihistamine, immunomodulator, immunosuppressant, herbal medicine, alternative medicine, etc.) are tried. Recently, a lot of studies were made. But there is no report about the effect of Samulsopungeum(SM) and Prednisolone(PN) on AD. So, author aimed to investigate the effects of SM and PN on AD of NC/Nga mice. Methods : Thirty two mice(8 Balb/c mice and 24 NC.Nga mice) were divided into four groups; Balb/c mice was normal group. NC/Nga mice were divide into three group : control, PN, SM group. AD was induced in the control, PN, SM group by spreading DNCB. Then normal saline, PN and SM were orally administered three times in a week for 8 weeks to the control, PN, SM group, respectively. We observed changes of clinical skin severity score, serum IgE, IgG1, IFN-$\gamma$, IL-2, IL-4, IL-5, IL-10, IL-13, and so on. We used one-way ANOVA test statistically(p<0.01). Results : The clinical skin severity scores of PN group and SM group in 8th week were decreased compared to the control group. Serum IgE, IgGl levels of PN group and SM group were significantly decreased compared to the control group. Serum IFN-$\gamma$ in SM group was significantly increased compared to the control group. But, Serum IFN-$\gamma$ in PN group was significantly decreased compared to the control group. Serum IL-10 levels of PN group and SM group were significantly decreased compared to the control group. Serum IL-2, IL-4, IL-5, IL-13 levels of PN group and SM group were significantly decreased compared to the control group. mRNA expression levels of IL-2, IL-4, IL-5, IL-13 in the dorsal skin tissues of PN group and SM group were significantly decreased compared to the control group. According to biopsy reports of the ear and skin tissues showed that the tissue damage of PN group and SM group were highly reduced compared to the control group. Creatinine, BUN, ALT, AST levels of PN group and SM group were normal. Conclusion : According to the above results, it is considered that SM is effective treatment for the AD.

$\gamma$-PGA는 우리 전통 콩 발효식품인 청국장의 끈적끈적한 점액성의 성분으로, 매우 다양한 기능을 가지고 있는 천연 소재이다. 이러한 $\gamma$-PGA가 아토피발진 억제 가능성을 알아보기 위해 NC/Nga 생쥐를 사용하여 in vitro 실험을 실시하였다. $\gamma$-PGA(PGA-HM, 분자량 300 kDa)를 초음파처리로 저분자화시킨 30 kDa 이하의 저분자 PGA-LM를 만들고, 고분자 PGA-HM과 PGA-LM을 사용하여 실험하였는데 동일한 결과를 얻어 PGA-LM 실험결과 중심으로 보고한 것이다. 아토피 피부발진 NC/Nga 생쥐의 비장에서 B 세포와 T세포를 순수 분리하여 항알레르기 작용에 대한 in vitro 실험을 실시하였다. PGA-LM은 hFCs에 대한 세포독성 실험에서 모든 농도에서 세포독성을 나타내지 않았다. PGA-LM이 B 세포 분화 및 활성화에 미치는 영향을 관찰하기 위하여, NC/Nga 생쥐의 비장에서 순수 분리한 B 세포에 anti-CD40/rmIL-4로 자극한 결과, 대조군은 전사인자인 NF-${\kappa}B$의 활성화로 IL-$1\beta$, IL-6, 그리고 TNF-$\alpha$ mRNA의 발현이 증가되었다. 그러나 PGA-LM과 양성대조군인 rmIL-10 투여군은 염증사이토카인 IL-$1\beta$, IL-6 그리고 TNF-$\alpha$ mRNA 유전자 발현이 감소하였고, IL-10 mRNA 유전자 발현은 증가하였으나 TGF-$\beta$ mRNA의 유전자 발현은 대조군과 큰 차이가 나타나질 않았다. 또한 CD4+ T 세포에 PGA-LM $100\;{\mu}g/ml$를 처리한 후 4일간 동시 배양하여 CD4+IFN-$\gamma$+와 CD4+CD25+foxp3+ Treg 세포를 세포내 염색으로 분석한 결과에서는 CD4+IFN-$\gamma$+인 Th1 세포의 증가와 CD4+CD25+foxp3+ Treg 세포를 증가시켜 알레르기반응에서 우위한 Th2 세포에서 Th1 세포로 전환시키는 면역조절 역할을 나타내었다. 이상의 결과로 NC/Nga 생쥐에서 PGA-LM은 염증유전자 발현을 억제시키고 IFN-$\gamma$+의 증가 및 조절 T 세포의 유도로 아토피피부염의 피부발진을 치료하는 면역조절제로 사용될 수 있을 것으로 생각된다.

Objectives The purpose of this study is to investigate the effect of SPDJTK(SoPungDoJeokTangKami) and concurrent administration of AJ(Atopy cream, Jawoongo)+SPDJTK on atopic dermatitis-like skin lesions by using in NC/Nga atopic dermatitis mouse induced by BMAC-induced mice. Methods Clinical skin score, hematology and Serum total IgE and IgG1 of NC/Nga atopic dermatitis mice were evaluated. Moreover, the cytokine level, total cell number, Immunohistochemical staining and Histological features of axillary lymph node(ALN), draining lymph node(DLN), peripheral blood mononuclear cells(PBMCs) and dorsal skin tissue were used in NC/Nga mice. Results Orally administrated SPDJTK with concurrent administration of SPDJTK and AJ decreased the clinical skin score, total cell number of WBC, eosinophils in blood, serum total IgE & IgG1, IL-5, IL-13, IFN-$\gamma$. Also, total cell number of ALN and dorsal skin tissue, absolute cell number of CD4+, CD8+, CD3+CD69+, CD3+CCR3+, CCR3+, CD4+CXCR5+ in ALN, absolute cell number of CD3+CCR3+, CCR3+ in DLN, granulocytes in PBMCs, activation cell number of CD3+CD69+, CCR3+, total cell number of CD3+ T cell in dorsal skin tissue were significantly decreased. Furthermore, thickness of epidermis, infiltrated inflammatory immune cell and mast cell in dermis, amount of Eotaxin2 mRNA, CCR3 mRNA in dorsal skin tissue, gene expression of IL-5, IL-13 mRNA in ALN, CD4+ Th cell in dorsal skin tissue and CCR3+ eosinophils in ALN were all significantly decreased. However, total number of DLN, absolute number of CD3e+ T cell and CD19+ B cell, absolute number of CD4+, number of Th cell in DLN and gene expression of foxp3 mRNA were significantly increased significantly. Conclusions Concurrent administration of SPDJTK and AJ on atopic dermatitis in NC/Nga atopic dermatitis mouse was very effective treatment for atopic dermatitis.

To examine the effects of HHCP on atopic dermatitis and its various immunopathologic parameters was induced by DNCB in NC/Nga mice and the animals were orally administrated with HHCP. We summarized the results obtained from serum levels of IgE and the numbers of various immune cells as follow. HHCP has no cytotoxic effects at the range of concentration (1-400 ${\mu}g$/ml) on fibroblast isolated from lung of BALB/c mice. HHCP significantly lowered the serum levels of IgE compared with control at 16 and 20 week. HHCP significantly reduced the number of CD19$^+$ cell in spleen and DLN, as well as the number of B220$^+$ /IgE$^+$ cell in DLN compared with control. HHCP significantly reduced the number of ${\alpha}$${\beta}$ TCR$^+$ in spleen and DLN, the number of CD8$^+$ in spleen compared with control, and also significantly reduced the number of CD3$^+$, CCR3, CD3$^+$/CD69$^+$, CD3/ CCR3, CD4$^+$, CD3$^+$/ CD4$^+$/CD45$^+$ cell in DLN. HHCP increased the number of NK$^+$ cells in spleen compared with control, in contrast significantly decreased the number of CD11c$^+$/ Classll$^+$ cell and CD11b$^+$/Gr-1$^+$ cell in DLN. Taken together, these results suggested that HHCP has suppressive effects on atopic dermatitis through the inhibition of IgE production and modulation of immune cell population in NC/Nga mice.

Objectives : Atopic dermatitis accompanies with severe pruritus and collapse of skin barrier, inflammation. Maifanite could be used as an ointment for skin disease. However, there have been few studies about maifanite uses for atopic dermatitis. We report the anti-inflammatory and promoting skin recovery effects of ionized maifanite on damaged skin barrier with experimentally elicited atopic dermatitis. Methods : Nc/Nga mice were divided into 3 groups: control group(CON), atopic dermatitis elicited group(AE group), ionized maifanite treated group after atopic dermatitis elicitation(MT group). After 5% SDS was applied D. pteronyssinus crude extract also applied for 3 weeks to elicit atopic dermatitis-like skin disease. MT group was treated for 3 weeks with ionized maifanite. Ionized maifanite was applied once a day and voluntarily administrated. AE group and control group were treated with normal saline in the same way. Results : In MT group, skin lesions like eczema were more improved than AE group. p-ERK1/2 positive reaction was reduced in MT group. MMP-9 and substance P positive reaction at dermal papillae was also reduced in MT group. With skin angiogram, capillary vessel decreased in MT group. Also, IL-4 positive reaction cell and STAT-6 positive reaction cell reduced more in MT group than in AE group. $NF-{\kappa}B$ p65 positive reaction cell and iNOS positive reaction cell also declined more in MT group than in AE group. Conclusions : It is supposed that ionized maifanite has anti-inflammatory effects on NC/Nga mice's atopic dermatitis with suppressing IL-4 production and Th2 cell differentiation, and controlling $NF-{\kappa}B$ activation.
