유산균이 활성화된 비만세포에서 발현하는 IL-4와 IL-13을 조절할 수 있는지를 분석하였고, GATA-1, GATA-2, NF-AT1, NF-AT2, NF-κB p65 전사인자의 활성을 억제하는지를 실험적으로 규명하였다. 이전 연구에서 T cell에서 CD4+/CD25+/foxp3+ 증가를 실험하여 항아토피 기능성이 있는 유산균을 탐색하였고, Staphylococcus aureus에 대한 항균력을 증가시키는 유산균의 이중배양법을 확인하였다. 여기서는 RBL-2H3 비만세포를 이용하여 이 배양법으로 배양한 유산균이 아토피 피부염의 원인이 되는 allergy 염증반응에서 얼마나 억제능을 갖는지 알아보았다. 그 결과 Lc. lactis culture with medium containing Lb. plantarum supernatants > Lc. lactis > Lc. lactis culture broth with medium containing Lb. plantarum culture broth > Lb. plantarum의 순으로 나타났다. 이 cell 수준(level of mast cells)에서의 순서는 이전 연구의 level of microorganisms (anti-S. aureus)에서의 아토피 유발인자 억제능 순서와 같다. 따라서 세포수준에서도 Lb. plantarum 배양상층액을 첨가한 배지에 Lc. lactis 배양한 경우가 활성화된 비만세포의 allergy 반응으로의 분화 및 활성을 가장 잘 억제하고 관련 유전자 발현을 선택적으로 조절하는 anti-allergy 효과를 나타낸다고 사료된다.

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.

Atopic dermatitis is one of the most common skin disease in children and a characteristic chronically recurrent form of dermatitis with a hereditary tendency, affecting infants and may extend to the childhood or th the adult age. Environmental factors, stress, and foodstuffs such as milk, egg may cause atopic dermatitis. Nc/Nga mice were used as an animal model for human atopic dermatitis. The divided by 4group such as normal group, BMAC group, FK506 group, MR group for this study raised in conventional conditions. To investigate effect of Chamomile German on atopic dermatitis in NC/Nga mice, the serum IgE and IgG1 level were measured while the severity degree of the skin lesion was examined by the naked eyes of two volunteers who were unaware of the treatment status. The results were the followings. 1. The score on the severity degree of skin dermatitis in FK 506 and MR group was lower than that in control group. 2. The serum IgE level in control group was higher 25% than that in normal group. 3. The serum level of IgE in FK506 and MR group compares to control group was decreased. 4. The serum IgG1 level was decreased more than 3.5 times in FK506 compared to control group while MR group had significantly less the serum IgG1 than control group. From the above results, treatment of Chamomile German oil had the effect on atopic dermatitis in NC/Nga mice. If scientific researches on aroma oil are performed in various way, aroma oil will be used to cure skin dermatitis as a alternative therapy in the future.

The purpose of this study is to investigate the prevalent allergens causing canine atopic dermatitis in Daejeon area. Twenty two dogs were diagnosed with atopic dermatitis by an using intradermal skin test (IDST). Allergens used for the IDST included 33 allergen extracts from nine allergen groups: house dust mites (HDM), house dust, moulds, trees, weeds, grasses, insects/fleas, epithelia and others. The 22 purebred dogs with atopic dermatitis enrolled in this study included Shi-tzus (10/22, 45.5%), Yorkshire terriers (5/22, 22.7%), Miniature pinschers (4/22, 18.2%), Pugs (2/ 22, 9.1 %) and Cocker spaniels (1/22, 4.5%). The age of onset of atopic dermatitis ranged from 5 months to 5 years old (median: 1.79 years). The males (12/22, 54.5%) and females (10/22, 45.5%) were almost equal. The number of positive reactions to allergens recorded in each dog with atopic dermatitis was 3 (9/22, 40.9%), 2 (8/22, 36.4%), 1 (3/ 22, 13.6%) and 4 (2/22, 9.1 %), respectively. The most common positive allergen reaction was HDM (52.6%). The other positive allergen reactions recorded were from house dust (17.5%), insects/fleas (15.8%), trees (5.3%), moulds (3.5%), kapok (3.5%), silk (3.5%), epithelia (1.8%), weeds (0%) and grasses (0%), respectively. Positive reactions recorded to Dermatophagoides farinae and D. pteronyssinus were in 53.3% and 46.7%, respectively. The IDST results demonstrate that the most common causative allergens in canine atopic dermatitis in Daejeon area were HDM.

Atopic dermatitis, caused by immune hyper-responsiveness, is wide spread in humans as well as in the dogs, especially in industrialized condition. Pet dogs are generally exposed to the same environment as their owners, and a significant portion of these animals are also known to suffer from this allergic disease. However, diagnosis and treatment methods of atopic dermatitis in animals have not been well established. We explored the possibility of using recently developed PG102 for the treatment of atopic dermatitis in the canine population. PG102 is a water soluble extract prepared from Actinidia arguta, and has been shown to produce significant therapeutic effect in variable allergy animal models. After oral administration of PG102 at a dose of 12.5 mg/kg daily for 4 weeks, severity of disease was greatly improved. IgE is one of representative members used to diagnose allergic diseases in humans. However, it is not well established whether there is any correlation between the serum level of IgE and atopic dermatitis. Our data indicated that dogs diagnosed to have atopic dermatitis contained higher level of serum IgE than the normal dogs and that treatment of dogs with PG102 significantly lowered the serum level of IgE. Taken together, this study demonstrated that PG102 treatment yielded significant amelioration of canine atopic dermatitis and down-regulation of serum IgE and that the serum level of IgE can be used as a convenient member for diagnosis of atopic dermatitis in dogs.

Background and Purpose : Oncheongeum(溫淸飮) composed of Samultang(四物湯) and Hwangryunhaedoktang(黃連解毒湯) was mainly used for healing metrorrhagia in the Qing dynasty of China. At present, Oncheongeum is used for treating a broad spectrum of diseases such as skin disease, stomatitis, behcets disease, diabetes mellitus and, especially in Japan, atopic dermatitis. To our knowledge, however, neither the precise constituents and their effects of Oncheongeum nor the criteria for the prescription of Oncheongeum were defined. To address this issue, we searched and performed analysis of Korean, Chinese and Japanese articles reporting the clinical and experimental studies of Oncheongeum. Methods : We searched articles in the national assembly library of Korea by using keyword 'Oncheongeum' korean. Similarly, we did chinese articles in the CNKI and japanese ones in the CiNii, respectively. Results : We found 13 korean articles about Oncheongeum in the national assembly library, 34 chinese articles in the CNKI, and 23 japanese in the CiNii. The papers were divided into clinical and experimental articles. The clinical articles were mainly published from China and Japan, and their subjects were predominantly on skin diseases. Conclusions : There were a lot of case reports about Oncheongeum used in the clinical studies. In order to better understand the effects of Oncheongeum, systematic review of the studies seems essential. The efficacy of Oncheongeum reported in the clinical studies should be supported by experimental data. Not much were clinical reports in Korea, although we are expecting more to come. It is possible to not only analyse but compare Oncheongeum with other prescriptions used for atopic dermatitis. More comprehensive and comparative analysis of three countries' prescriptions might provide a way of how to standardize prescriptions, which leads oriental medicine to an evidence based medicine.

This study investigated the clinical parameters of atopic dermatitis and evaluated the inhibitory effects of Black currant seed oil for atopic dermatitis by using a Dinitrochlorobenzene(DNCB) induced BALB/c mice model. Five-week-old BALB/c mice were divided into four groups: normal group (N, non-treated), control group (C, atopic dermatitis-induced), positive control group (PC, Tacrolimus ointment-treated against induced atopic dermatitis, PC), experiment group (E, Black currant seed oil-treated against induced atopic dermatitis). After induction of atopic dermatitis by DNCB, the erythema, edema, eschar, and scratching were severely observed. The symptoms of atopic dermatitis were improved after 2 weeks, and almost disappeared after 4 weeks in PC and E group. The increased frequencies of scratching in C group were decreased in PC and E group. Transepidermal water loss, erythema index and serum IgE level were significantly decreased in E and PC compared to that in C after 4 weeks of the treatment. The results indicated that Black currant seed oil can relieve atopic dermatitis symptoms effectively, and may be possibly used as a functional material for suppression of atopic dermatitis.

Atopic dermatitis (AD), a chronic inflammatory skin disease, is characterized by itchy and age-dependent lesions. Previous studies have shown that pulsed electromagnetic field (PEMF) significantly improved chronic ulcers and ununited fractures, providing an evidence for the application of PEMF in resolving inflammation caused by AD. This study investigated the anti-inflammatory effect of PEMF on DNCB-induced AD in animal models. Five male hairless mice (6 weeks old) per group were assigned to a normal group, a sham group, and two PEMF groups (15Hz, 75Hz). Mice were treated with 2,4-Dinitrochlorobenzene (DNCB) to induce uniform AD among all groups excluding a normal group. To examine the inflammatory progress and the improvement of AD after the PEMF stimulation, images are taken with various cameras for non-invasive evaluation and the results are expressed using principal component analysis (PCA) for visualization. The results of this study demonstrated that PEMF effectively improved skin lesions without the use of drugs.
