  • 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.

  • Objectives : A bibliometric approach using network analysis was applied to explore the global trends of research on herbal medicine for atopic treatment. Methods : Articles related to herbal medicine on atopic treatment from 2003 to 2022 were retrieved from Web of Science Core Collection. Extracted records were analyzed according to the publication year, research area, journal title, country, organization, author and keyword. The VOSviewer program was used to visualize the trends and the research hotspots in herbal medicine for atopy. Results : Analysis of 406 articles indicated the consistent increase of using herbal medicine for atopic treatment over the last 20 years. The most productive country and research organization in issuing articles were South Korea and Kyunghee university. Many articles have been published in research areas such as 'integrative complementary medicine' and 'pharmacology pharmacy'. By evaluating the total link strength, the average publication year and the average citations of countries and authors, the influential countries and authors were identified. A network analysis based on the co-occurrence and the publication year of keywords revealed the relevant characteristics and trends of herbal medicine for atopy. The most up-to-date keywords were 'topical application', 'skin barrier' and 'care'. Conclusions : This bibliometric study examined the overall trends and the time-based development of herbal medicine for atopic treatment. The current study would be useful not only for grasping the global network hub of research on herbal medicine for atopic treatment, but also to explore the new directions for future research.

  • Fifteen dogs with superficial pyoderma were investigated clinically. Dermatological signs were mainly consisted of papule (66.6%), pustule (86.6%), epidermal collrarette and patchy (40%), and hyperpigmentation (53.3%). Distribution of skin lesion were consisted of back (35.5%), abdomen (29.0%), axillary (6.4%), leg (3.2%), neck (3.6%) and foot (16.1%), respectively. In pustular cytology PMN cells and cocci were examined. Cephalexin was very effective antibiotics on superficial pyoderma at administration of 30mg/kg bid P.O. for 3 weeks. Hyperadrenocorticism and atopy were diagnosed as a primary cause on pyoderma in 2 dogs.

  • Severe childhood asthma is a complicated and heterogeneous disorder with distinct phenotypes. Children with severe asthma have more persistent symptoms despite receiving treatment, more atopy, greater airway obstruction, and more air trapping than those with mild-to-moderate asthma. They also have higher morbidity and substantial airflow limitations that persist throughout adulthood. Identification of the phenotype clusters and endotypes of severe asthma can allow further modulation of the natural history of severe asthma and may provide the pathophysiologic rationale for appropriate management strategies.

  • Objective : We wished to examine closely effect that Kami-KangHwalSan medicines used to atopy dermatitis disease patient get in atopy eruption control experimentally. Materials and Methods : Atopic dermatitis (AD) usually develops in patients with an individual or family history of allergic diseases, and is characterized by chronic relapsing inflammation seen specially in childhood, association with IgE hyperproduction and precipitation by environmental factors. However, the exact etiology of AD has been unclear. To further explore the pathogenesis and treatment of AD, a suitable animal model is required. We found that skin lesions, which were chnically and histologically very simlar to human AD, mite antigen-induced dermatitis on the face, neck, ears and dorsal skin of inbred NC/Nga mice.

  • Objectives : The aim of this study is to investigate anti-inflammatory activity using various extracts of rice straw (DaoCao) extract (RS).Methods : To investigate the anti-inflammatory effect of RS, we examined the effect of RS on cytokines production on THP-1 cell. Cells were cultured in incubator (37℃, CO25%, 0.5% FBS-RPMI, 1X106cells/ml). One hour after,Dermatophagoides pteronissinus(Dp., 10 ug/ml) was treated into cell and at 6 hour after, each different concentrations(0.1, 1 and 10 ug/ml) of RS were treated. The cells were incubated for 16 hours and harvest the supernatant. The levels of IL-4, IL-5, IL-6, IL-8, MCP-1 and TNF-αwere determined using a commercially available ELISA kit.Results : We investigated whether RS has the inhibition of inflammatory response in Jurkat cells and THP-1 cells. RS suppressed secretion of IL-4, IL-5, and TNF-αinduced by house dust mites in Jurkat cells. It showed significant effects for all concentrations. RS suppressed the increased expression of IL-6, IL-8 and MCP-1 after treatment with mite in THP-1 cells. These results suggest that RS may be used as a valuable agent for treating allergic diseases such as atopy due to its anti-inflammatory property.Conclusions : RS showed significant biological activities with anti-inflammatory in the human T cells. These results suggest that RS may be used as a valuable agent for treating allergic diseases such as atopy due to its anti-inflammatory property. In terms of Korean traditional medicine, we expect the results to contribute to building of EBM (Evidence-Based Medicine).

  • The purpose of this study was to investigate the anti-allergy activities of persimmon leaf extract (PLE) on a phthalic anhydride (PA)-induced allergic mouse model. A human leukemic mast cell line (HMC-1) was used to examine the inhibitory activity of PLE on the histamine release by human leukemic mast cells. PLE inhibited histamine release from HMC-1 cells in response to cross-linkage of high-affinity IgE receptor-${\alpha}$ ($Fc{\varepsilon}RI{\alpha}$). Additionally, a PA-induced allergic mouse model was used to investigate the effects of PLE in vivo. Mice were orally administrated with or without PLE of single dose (250 mg/kg/day) for 31 days. Oral intake of PLE significantly inhibited passive cutaneous reactions. Oral administration of PLE to PA-induced allergic mice also led to a striking suppression of the development of contact dermatitis, ear swelling and lymph node weight. In addition, PA-specific IL-4 production of draining lymph node cells was markedly diminished by PLE oral administration, but not IFN-${\gamma}$. Furthermore, PLE treatment suppressed PA-induced thymus and activation-regulated chemokine (CCL17) and cutaneous T cell-attracting chemokine (CCL27) expressions in ear tissues. Based on these results, we suggest that PLE may have therapeutic potential as an effective material for management of irritant contact dermatitis or related inflammatory diseases.

  • Objectives: This study was performed in order to determine airborne fungi levels in homes and find related factors that may affect airborne fungi concentration. Methods: Fifty homes were study subjects for measuring airborne fungi. For sampling airborne fungi, the impaction method on agar plates was used and samples were counted as colony forming units per cubic meter of air ($CFU/m^3$). In addition, information regarding housing characteristics and atopic disease in each home were collected via questionnaire. Results: The geometric means (GM) of airborne fungi concentrations in fifty living rooms and bedrooms were 68.03 and 62.93 $CFU/m^3$, respectively. The GM of airborne fungi concentration in atopy homes was 78.42 $CFU/m^3$. This was higher than non-atopy homes' 54.34 $CFU/m^3$ (p-value=0.051). In the results of the multiple regression analysis, outdoor airborne fungal concentration proved a strong effective factor on indoor airborne fungal concentration. Also, construction year, floor area of house, indoor smoking and frequency of ventilation were factors that showed a significant association with indoor airborne fungi concentration. Conclusions: The results of this study show that some housing and living characteristics may affect the development and increase of airborne fungi. In addition, exposure to airborne fungi may be a risk factor for the prevalence of childhood atopic diseases.
