본 연구에서는 카모마일, 라벤더, 샌달우드를 혼합한 아로마 혼합오일(CLS)과 면역억제제(FK506)의 아토피 피부염 치료효과를 알아보기 위하여 혈청 중 IgE(Immunoglobulin E)와 IgG1(Immunoglobulin G1)의 수준의 감소효과, 피부 임상지수를 이용한 육안평가 등을 실시하였다. 그 결과 IgE 수준을 낮추는데는 CLS가 더 효과적이었고, IgG1 수준을 감소시키는 데에는 FK506이 더 효과적인 것으로 나타났다. 육안평가 결과를 통하여 아토피 피부염을 가진 마우스에 FK506과 CLS를 도포한 후 2주까지는 아토피 증상을 더 악화시켰으며 4주후부터는 증상완화가 현저하게 나타남을 확인할 수 있었다. 특히 FK506의 효과가 두드러졌는데 이는 IgG1 수준감소와 관련이 있는 것으로 사료되며 이와 관련하여 보다 심도있는 실험 조사가 필요하겠다. 이상의 결과로부터 카모마일 저먼, 라벤더, 샌달우드의 아로마 혼합오일이 아토피 피부염의 개선에 효능이 있음이 인정되었고 이와 같이 장기간 피부에 도포하여 치료하는 경우 CLS가 아토피 치료의 한 방법으로서 가능성이 보임을 확인하였음에 본 연구의 의의가 있다.

아토피 피부염(Atopic dermatitis, AD)은 주로 5세 이전에 발병하여 심한 가려움을 동반하는 만성 염증성 피부질환이다. 본 연구의 목적은 NC/Nga 마우스를 AD 유사 증상에 대한 405 nm+ 850 nm LED 광선 치료의 효과를 조사하는 것이다. 마우스는 Normal (Vehicle), 아토피성 피부염 유발군 (CON), 405 nm+ 850 nm LED 광선 치료군 (LED)으로 나누어 난괴법을 이용하여 무작위 배치하여 실험을 진행하였다. LED 실험군은 하루 10분씩 405 nm+ 850 nm 파장의 LED 치료를 7일 간 실시하였다. LED 광선치료 연구는 Dermatics 점수의 개선을 측정하고 피부염으로 인한 표피조직 두께 감소를 관찰하였다. LED 광선 요법으로 인한 혈청 IL-1𝛽의 현저한 감소와 경피 수분 손실 및 혈청 IgE 농도 결과를 바탕으로 LED 광선 치료는 아토피 유발 생쥐의 정상적인 피부 상태 회복에 도움을 주었다. 본 연구 결과는 아토피 피부염 마우스 모델에서 적외선 영역의 광선과 blue light 영역의 광선의 동시 조사치료가 아토피 피부염 치료에 뛰어난 효능을 가지며, 두 파장의 LED의 동시 사용 가능성에 대하여 시사하였다.

본 실험에서는 CGT의 항염증과 관련한 다양한 실험을 실시하였다. In-vitro 실험에서 MTT, NO, ROS와 같은 염증 매개 물질 실험은 RAW 264.7 세포를 이용하여 실시하였다. In-vivo 실험은 아토피피부염 동물 모델인 NC/Nga 생쥐에서 항염증과 관련한 인자 및 조직학적 변화 등을 관찰하였다. CGT는 RAW 264.7 세포에서 100% 이상의 생존율을 나타냈으며, LPS를 이용한 NO와 ROS의 검사에서도 효과를 나타내었다. CGT 처치 그룹은 혈청 내 IL-$1{\beta}$와 IL-6, TNF-흰 에서 53%, 43%, 57%의 유의성 있는 감소를 나타내었고, IgE 역시 56%의 감소를 보였다. 또한, 피부에 지방세포의 침윤을 억제하고, 표피 및 진피의 두께 역시 감소하였다. 그 결과 CGT는 NC/Nga 생쥐에서 항염증에 효과를 나타내었다. 따라서 CGT는 아토피피부염과 염증 치료에 좋은 효과가 있다고 제안하는 바이다.

Objectives : In this study, Samhwangsaejaegami extract was tested to prove its anti-atopic dermatitis effect on NC/Nga mice. Methods : In order to evaluate the external use effects of Samhwangsaejae extract on anti-atopic dermatitis, the expression of filaggrin, serine palmitoyltransferase(SPT), and COX-2 were analyzed. In vivo study, clinical skin severity score, IgE, IL-4, IL-5 and IL-6 level were analyzed through NC/Nga atopic mice model after 12 weeks external treatment. Results : In vitro study results showed the reduction in the expression of filaggrin, SPT, and COX-2. In vivo study results demonstrated the significant reduction in clinical skin severity score, IgE, IL-4, IL-5, IL-6 expression level. Conclusions : These results showed Samhwangsaejaegami extract can be a promising candidate for anti-atopic dermatitis treatment.

Objectives : The aim of this study is to report the effect of Capsosiphon fulvescens(Maesangi) extract(MSE) on contact dermatitis(CD). Methods : CD induced by Dermatophagoides farinae body(Dfb) in NC/Nga mice. 4% sodium dodecyl sulfate(SDS) $150{\mu}l$ and Dfb(10mg/ml) ointment 100mg were topically treated twice a week for four weeks. MSE 200 mg/kg was topically treated every 4weeks. Every week, we examined the skin lesions, weight of spleen and lymph node, epidermal thickness, production of Tumor necrosis factor-alpha($TNF-{\alpha}$) and interleukin-6(IL-6). Results : MSE reduced features of Dfb-induced skin lesions, weight of spleen and production of $TNF-{\alpha}$. MSE significantly reduced weight of lymph node, epidermal thickness, number of mast cells and production of IL-6. Conclusions : MSE may have a potential therapeutic effects for CD by suppressing allergic inflammation.

Objective : This study was carried out to compare Saengmaeksan-gamibang(SG) to Saengmaeksan(SM) on the efficacy of moisturization, skin whitening, anti-inflammation, and anti-allergy in atopic dematitis using NC/Nga mice model. Methods : We assessed the effects of SG and SM on tyrosinase, filaggrin, serine-palmitoyl transferase(SPT), COX-2, AP-1 in vitro, on IgE, IL-4, IL-5, IL-6, IgM, IgG1, IFN-${\gamma}$ in vivo with NC/Nga mice. Results : 1. SG increased the tyrosinase inhibition activity and the levels of filaggrin and SPT, decreasing the level of COX-2. 2. On the other hand, SM decreased the tyrosinase inhibition activity and the levels of filaggrin and SPT, increasing the level of COX-2. 3. Serum IgE, IL-4, 5, 6, IgM, and IgG1 were decreased in both SG group and SM group compared to the control group. The decrease degree in these factors was higher in SG than in SM. 4. Serum IFN-${\gamma}$ was increased in both SG group and SM group compared to the control group. The increase degree in IFN-${\gamma}$ was higher in SG than in SM. Conclusion : As the result of the above experiments, it was proved that SG has the moisturization, skin whitening, anti-inflammation, and anti-allergy effects, which are greater than those of SM, and provides the significant efficacy on atopic dermatitis treatment.

This study was conducted to determine if YJ-1, a novel herbal complex from a mixture of six oriental herbs (Hydnocarpi Semen, Sesami Semen, Dictamni Radicis Cortex, Momordicae Semen, Xanthii Fructus, and Sophorae Radix), has therapeutic properties for the treatment of atopic dermatitis (AD). Using AD like symptom-induced NC/Nga mice by 1-chloro 2,4-dinitrobenzene (DNCB), the effectiveness of YJ-1 on AD was evaluated. Elidel cream$^{(R)}$ (1% pimecrolimus) was used as a control. Dermal application of YJ-1 reduced major clinical signs of AD such as erythema, pruritus, lichenification, edema/escoriations, and dryness. Interestingly, YJ-1 more improved AD-related symptoms including decrease of spleen weight, IL-4, and IgE level in the serum as well as reduction of scratching counts and clinical skin severity in the NC/Nga AD mouse model. Especially, treatment of YJ-1 at 20% in NC/Nga mice more effected than Elidel cream. These results suggest that the ointment of YJ-1 may enhance the process of AD healing by alleviating allergic reaction and has potential for therapeutic reagent for the treatment of AD.

Background: Allergic inflammation was induced by activated Th2 lymphocytes, leading to IgE production and eosinophil activation. A Th2 disproportion was shown in atopic children soon after birth. During specific allergen stimulation, an increase of Th2 cells was observed in most cases. In this study, we prepared new screening "whole blood" system for searching the anti-atopic materials. Cytokine production and IgE secretion from whole blood system were assessed and we confirmed the results by using animal system. Methods: Pathological features in NC/Nga mice are similar to those observed in human atopic dermatitis. Whole blood from NC/Nga mouse was stimulated by using TNCB (Th2 activator) or candidate materials of anti-atopic dermatitis, and the production of cytokines (IL-4, IL-12, and IFN-${\gamma}$) were measured by ELISA. In order to confirm the results of whole blood system, in vivo test was done by using NC/Nga mice. Results: In whole blood system, LPS and extracts of green tea, hardy orange and onion induced the production of IL-12 and IFN-${\gamma}$ while they reduced the production of IL-4. Also, LPS and extracts of onion reduced IgE production. Though atopic dermatitis was observed from a mouse stimulated with TNCB, it was not when a mouse was co-stimulated in LPS or extracts of onion. The results are same as those observed in whole blood system. Conclusion: Whole blood system was simple and speedy methods for searching a materials compared with the conventional high-cost animal system. And the results using whole blood system was proved to be reliable in our experiments for screening anti-atopic material. We expect that the system can be applied to other experiments for searching similar materials.
