  • Although atopic dermatitis (AD) is known to be a representative skin disorder, it also affects the systemic immune response. In a recent study, myoblasts were shown to be involved in the immune regulation, but the roles of muscle cells in AD are poorly understood. We aimed to identify the relationship between mitochondria and atopy by genome-wide analysis of skeletal muscles in mice. We induced AD-like symptoms using house dust mite (HDM) extract in NC/Nga mice. The transcriptional profiles of the untreated group and HDM-induced AD-like group were analyzed and compared using microarray, differentially expressed gene and functional pathway analyses, and protein interaction network construction. Our microarray analysis demonstrated that immune response-, calcium handling-, and mitochondrial metabolism-related genes were differentially expressed. In the Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology pathway analyses, immune response pathways involved in cytokine interaction, nuclear factor-kappa B, and T-cell receptor signaling, calcium handling pathways, and mitochondria metabolism pathways involved in the citrate cycle were significantly upregulated. In protein interaction network analysis, chemokine family-, muscle contraction process-, and immune response-related genes were identified as hub genes with many interactions. In addition, mitochondrial pathways involved in calcium signaling, cardiac muscle contraction, tricarboxylic acid cycle, oxidation-reduction process, and calcium-mediated signaling were significantly stimulated in KEGG and Gene Ontology analyses. Our results provide a comprehensive understanding of the genome-wide transcriptional changes of HDM-induced AD-like symptoms and the indicated genes that could be used as AD clinical biomarkers.

  • 본 연구에서는 DNCB 도포를 통해 아토피 피부염을 유발시킨 NC/Nga mice에 율피 발효물을 각각 0.1%, 1%, 5%로 도포하고 항아토피 효능을 평가하였다. 율피 발효물의 유효성분은 HPLC 분석 결과, gallic acid와 ellagic acid가 각각 10.18 mg/g, 2.14 mg/g 함량을 나타내었다. 실험군 간의 유의적 체중 변화는 관찰되지 않았으며, 육안 평가를 통해 홍반, 가려움과 피부건조, 부종과 혈종, 짓무름 그리고 태선화와 같은 일반적인 아토피 피부염 증상의 심각도를 측정한 점수 결과에서는 DNCB 도포를 통해 아토피 피부염을 유발한 atopic dermatitis(AD)군($13.17{\pm}0.40$)과 비교 시, 아토피 피부염 유발 후 5% 율피 발효물을 도포한 fermented Castanea crenata inner shell(FCS) 5군에서 $7.50{\pm}0.43$ 으로 나타나 아토피 피부염 증상이 빠르게 개선되는 것을 확인하였다(P<0.01). 피부 측정 기기인 MPA5 580을 이용하여 피부멜라닌지수, 피부홍반지수, 피부수분지수를 측정한 결과, AD군은 각각 $296.61{\pm}8.11$, $264.33{\pm}10.15$, $3.15{\pm}0.54$를 나타내었으며 FCS 5군은 각각 $105.86{\pm}2.92$, $199.56{\pm}4.22$, $17.62{\pm}1.75$로 개선효과가 유의적으로 나타났다(P<0.05). 각 실험군 mice의 면역반응을 확인하기 위해 비장 무게(mg)를 체중(g)으로 나누어 산출한 비장 수치의 경우, 아토피 피부염 유발로 인해 AD군에서 증가된 비장 수치($5.55{\pm}0.31$)가 FCS 0.1군, FCS 1군, FCS 5군에서는 각각 $4.53{\pm}0.24$, $3.80{\pm}0.40$, $3.32{\pm}0.24$로 나타나 율피 발효물의 도포 농도에 의존적으로 감소되는 경향을 나타냈으며 특히 FCS 5군에서는 유의적으로 낮게 나타났다(P<0.05). 이는 율피 발효물이 아토피 피부염 상태에서 증가된 비장 내 T-림프구를 효과적으로 억제할 수 있음을 나타낸다. Quantitative real-time PCR을 통해 피부조직에서 IL-$1{\beta}$, TNF-${\alpha}$와 같은 염증 유전자의 발현 변화를 분석한 결과, 두 유전자 모두 정상군의 relative quantification값이 1일 때 AD군은 각각 1.30, 1.26으로 증가되었으며 FCS 5군에서는 1.11, 0.93으로 나타나 율피 발효물 도포에 의한 유의적인 감소(P<0.05)를 확인할 수 있었다. 아토피 피부염의 면역학적 지표인 혈청 내 IgE 함량을 분석한 결과에서는 각 실험군 간의 유의적 차이는 보이지 않았으나 AD군($1,628.71{\pm}202.59ng/mL$)과 비교 시, 율피 발효물을 도포한 FCS 0.1군, FCS 1군, FCS 5군에서 각각 $1,530.15{\pm}198.70ng/mL$, $1,462.15{\pm}83.79ng/mL$, $1,187.47{\pm}140.09ng/mL$로 나타나 율피 발효물 도포에 의해 감소되는 경향을 확인할 수 있었다. 따라서 율피 발효물은 아토피 피부염 증상 개선을 위한 기능성 천연물의 소재로 활용될 수 있을 것이라 생각된다.

  • Objectives: The goal of this study was to investigate the short-term effect of ambient air pollution on emergency department (ED) visits in Seoul for asthma according to patients' prior history of allergic diseases. Methods: Data on ED visits from 2005 to 2009 were obtained from the Health Insurance Review and Assessment Service. To evaluate the risk of ED visits for asthma related to ambient air pollutants (carbon monoxide [CO], nitrogen dioxide [$NO_2$], ozone [$O_3$], sulfur dioxide [$SO_2$], and particulate matter with an aerodynamic diameter <$10{\mu}m$ [$PM_{10}$]), a generalized additive model with a Poisson distribution was used; a single-lag model and a cumulative-effect model (average concentration over the previous 1-7 days) were also explored. The percent increase and 95% confidence interval (CI) were calculated for each interquartile range (IQR) increment in the concentration of each air pollutant. Subgroup analyses were done by age, gender, the presence of allergic disease, and season. Results: A total of 33 751 asthma attack cases were observed during the study period. The strongest association was a 9.6% increase (95% CI, 6.9% to 12.3%) in the risk of ED visits for asthma per IQR increase in $O_3$ concentration. IQR changes in $NO_2$ and $PM_{10}$ concentrations were also significantly associated with ED visits in the cumulative lag 7 model. Among patients with a prior history of allergic rhinitis or atopic dermatitis, the risk of ED visits for asthma per IQR increase in $PM_{10}$ concentration was higher (3.9%; 95% CI, 1.2% to 6.7%) than in patients with no such history. Conclusions: Ambient air pollutants were positively associated with ED visits for asthma, especially among subjects with a prior history of allergic rhinitis or atopic dermatitis.

  • 식품알레르기는 알레르기 행진의 시작 단계로 원인 식품의 섭취 제한으로 인하여 성장기 아동의 영양 불균형과 아동을 비롯한 가족구성원의 삶의 질을 저하시키는 원인이 될 수 있다. 이에 본 연구는 2세 이상의 영유아 및 학령기 식품알레르기 아동의 주양육자인 어머니를 대상으로 자녀의 식품알레르기로 인한 양육부담을 정량화하여 자녀의 식품알레르기가 부모의 삶의 질에 미치는 영향을 분석하고자 하였다. 식품알레르기 아동 부모의 양육부담은 정서적 고충, 일상생활 제약에 대한 2개의 하부 요인으로 세분화되며, 자녀의 연령 증가, 섭취 제한 식품의 수, 일부 알레르기질환 진단 여부가 양육부담의 감소 및 증가에 유의한 영향을 미치는 것으로 분석되었다. 이처럼 식품알레르기 아동은 식품알레르기가 다른 알레르기질환으로 이행되지 않도록 전문 의료진에 의한 진단과 증상관리가 필수적이며, 환아를 비롯한 가족 구성원에 대한 주변의 지지와 간호 중재가 동반되어야 한다. 또한 성장기의 식품알레르기 아동은 식품 항원에 대한 식품경구유발시험 등의 정확한 임상 진단을 통해 필수 영양소를 포함한 식품의 과도한 섭취 제한을 방지해야 한다. 지역사회와 의료기관은 식품알레르기의 예방 및 증상완화를 위한 맞춤형 영양교육, 대체 식품에 대한 정보 제공 등의 현실적 지원과 정서적 지지를 병행해야 한다. 이처럼 다양한 형태의 사회적 노력과 제도적 방안을 통해 식품알레르기 아동의 삶의 질을 향상시키고 부모의 양육부담 대처능력을 강화해야 할 것이다.

  • Objectives: The aim of this study was to investigate airborne pollen counts, inhalant allergen sensitization rate, and allergic disease prevalence among elementary school children in Ulsan, South Korea during 2012-2018. Methods: Burkard samplers for pollen were installed on rooftops in suburban and urban areas in Ulsan. A 24-hour sampling of airborne allergens was conducted six days/week from January 1, 2013 to November 31, 2018. Skin prick tests were done with a total of 4,246 primary school students residing in urban and suburban areas in 2012, 2014, 2016, and 2018. This study examined sensitization to 20 major inhalant allergens. Results: The highest monthly counts of airborne pollen were observed in April and September each year. Among the pollen identified over the six years, pine showed the highest pollen counts (44.3%), followed by oak (22.3%), alder (6.3%) and Japanese hops (4.3%). Tree pollen predominated from March to June, and weed pollen predominated from August to October. Higher sensitization rates for inhalant allergens were observed in Dermatophagoides farinae (42.4%), Dermatophagoides pteronyssinus (43.6%), cat fur (12.1%), birch (9.9%), oak (9.6%), and alder (8.7%). The inhalant allergen sensitization rate was highest in the group with comorbidity (asthma and/or rhinitis and atopic dermatitis), and respiratory allergic disease (asthma and/or rhinitis) was higher than that of atopic dermatitis. Conclusion: Both the counts of tree pollen in the air and the sensitization rate for tree pollen were high in Ulsan. The temporal change in respiratory allergic diseases was similar to that for the sensitization rate of tree pollen, such as oak. In the future, it is considered that additional continuous research on various inhalant allergens and pollen should be conducted.

  • Background : Allergic rhinitis is found in approximately 20% of the general population. And the prevalence of allergic rhinitis in the pediatric population also appears to be rising. Despite allergic rhinitis reportedly occurs very frequently, this disease is often overlooked or undertreated. The oriental medicine, allergic rhinitis is belong to the BiGu, BunChe. The symptoms are watery rhinorrhea, sneezing and nasal obstruction. The cause of disease is the weak of lung, spleen and kidney, and invasion in to nasal cavity of Poong Han etc a wrong air. Objective : To allergic rhinitis patients, we use herbal medicine and acupuncture treated. To demonstrate the effect of oriental medicine therapy in the allergic rhinitis before and after treatment. Materials and methods: Thirty five patients (18 male and 17 female) treated in our hospital between February 2001 and October 2001 were studied. Ages ranged from 10 to 56 years (mean age : 27 years). Seventy seven patients had a underlying family history (allergy or sinusitis of parents or brothers). In the past history, 63% patients have atopic disease. Illness period was from 1 month to 20 years (mean period : 5.7 year). Mean duration of treatment were 39 days. Gamihyunggyeyungyo-tang was administered mainly. Result : The symptoms of allergic rhinitis were nasal obstruction(94%), rhinorrhea(86%), itching(80%), sneezing(60%), eye itching(17%), headache(11%), nose bleeding(8%) and nose pain(6%). Compared with before and after treatment, the fourth symptoms of allergic rhinitis - sneezing, rhinorrhea, nasal obstruction and itching- improved significant statistically. (significant <0.005) Conclusion : We know that herbal medicine therapy and acupuncture were the effective treatment of Allergic rhinitis.

  • Paranasal sinusitis, especially chronic is one of the most common diseases in the field of otolaryngology. It is similar to Bee Yeun(鼻淵) in oriental medicine. Most cases of sinusitis are due to anatomical abnormalities within ostiomeatal unit or disturbed mucocilliary flow. The ostiomeatal unit is the first place of contact with bacteria and allergens during aspiration, and it can be obstructed easily by minute mucosal swelling due to anatomical narrowness. Therefore the treatment of paranasal sinusitis is not easy and often leads to recurrences in spite of long term treatment or surgical therapy. We studied 83 patients who had visited our hospital with complaints of nasal symptoms; they had been diagnosed as having paranasal sinusitis through an endoscopy or CT scan in another hospital and were diagnosed as the paranasal sinusitis through a PNS series. The results were as follows: 1. Age and sex distribution: The most common occurence was found between 6-10 and 1-5 years old. The Males Were 52($62.7\%$) and Females were 31($37.3\%$). 2. By residence 58 cases lived in apts: 25 lived in houses. 3. The longest duration of disease varied from a lower of 13 to a higher of 36 months in 22 cases and from 7 to 12 months in 21 cases. 4. The most common complication & past history with otolaryngologic or allergic disease were adenoid or tonsil hypertrophy & tonsillectomy and adenoidectomy (21 cases). In decreasing order the others were atopic dematitis, otitis media with effusion and allergic rhinitis. 5. Distribution of paranasal sinus disease was most common in both maxillary sinuses in 52 cases. 12 cases showed a normal PNS X-ray series but these had been diagnosed as paranasal sinusitis with an endoscopy or CT scan in another hospital. 6. Common sinusitis - related symptoms were from highest incidence to lowest nasal obstruction, postnasal drip rhinorrhea, frontal headache, cough with sputum. 7. The most administered of prescription was Gamibangpoongtongsungsan and Sunbangpaedoksan extract. 8. In 26 cases the subjects showed significant improvement symptoms in PNS X-ray series : In 21 case showed partial improvement symptoms.

  • Objectives: Stress is considered a causal factor in many diseases, allergic disease being one of them. The prevalence of allergic disease is increasing in Korea, but the relationship between allergic symptoms and stress is not empirically well known. We aimed to evaluate the relationship between allergy-related symptoms and stress in children and adolescents. Methods: We investigated 698 children and adolescents living in Gwangyang Bay, Korea, using a multi-stage cluster sampling method. Using the International Study of Asthma and Allergies in Childhood and the Psychosocial Well-being Index, these subjects were surveyed on allergy-related symptoms and psychosocial stressors in their lives, respectively. We used a multivariate logistic analysis for odds ratios for the complaint rate of allergic symptoms, after adjusting for age, gender, household income, body mass index, and residence. Results: After adjustments, lifetime rhinitis (odds ratio [OR], 1.024), rhinoconjunctivitis (OR, 1.090), diagnosis of itchy eczema (OR, 1.040), treatment of itchy eczema (OR, 1.049), 12-month allergic conjunctivitis (OR, 1.026), diagnosis of allergic conjunctivitis (OR, 1.031), and treatment of allergic conjunctivitis (OR, 1.034) were found to be significantly associated with stress. Conclusions: Our results support the notion that there is a relationship between stress and allergic symptoms in children and adolescents. Further research into any causal relationship between stress and allergies, as well as preventative public health plans for decreasing stress in children and adolescents are needed.

  • Purpose: Celiac disease (CD) is an autoimmune disorder of the small intestine caused by an abnormal immune response to gluten proteins and is often characterized by gastrointestinal symptoms. Food allergy (FA) is an adverse immune sensitivity to ingested food proteins leading to inflammation in various organs including the gastrointestinal tract. The relationship between CD and FA remains unclear. This study aimed to assess the prevalence and clinical relevance of immunoglobulin E (IgE)-mediated food sensitization in children with CD. Methods: Fifty-nine children diagnosed with CD were reviewed for clinical symptoms and evidence of IgE-sensitization to food and airborne allergens using the PolyCheck method. Results: IgE-mediated sensitization has been diagnosed in 20.3% of children with CD (CD/A). In the CD/A group, 58.3% of children were sensitized to food and 66.7% to airborne allergens. Further, 41.7% of patients with CD and allergy reported gastrointestinal tract symptoms associated with the ingestion of sensitizing foods. Analysis of the clinical status revealed that the incidence of other allergic disorders in the CD/A group was as follows: atopic dermatitis (33.3%), asthma (25.0%), and allergic rhinitis (16.7%). The percentage of eosinophils was significantly higher in the CD/A group than in the CD group (0.33±0.25 vs. 0.11±0.09; p=0.006). Conclusion: The diagnosis of CD does not exclude FA. The gastrointestinal symptoms in children with CD may be the result of both CD and FA; therefore, children with CD should be evaluated for the presence of FA regardless of age.

  • This study was conducted on the nutritional status of 1,805 patients with allergic diseases (atopic dermatitis, allergic rhinitis, and asthma) aged 19 to 64 years according to their state of depression, based on the data from the Korea National Health and Nutrition Examination Survey (KNHANES). The Patient Health Questionnaire-9 (PHQ-9) was used to diagnose depression. Subjects with a score of 10 or more were categorized into the depression group (n=152) and the rest into the non-depression group (n=1,653). The results of this study were as follows: The proportion of women (75.7%) was higher than that of men (24.3%) in the depressed group (P<0.01). In terms of energy intake per 1,000 kcal, both men and women in the depressed group showed a lower energy intake than the non-depressed group and this intake was less than the estimated energy requirement (EER). The nutrient intakes of protein, calcium, phosphorus, iron, vitamin A, thiamine, riboflavin, niacin, folic acid, and vitamin C were below the estimated average requirement (EAR). Also, the intakes of fiber and potassium were less than the adequate intake (AI) (P<0.001). In the lifestyle parameters, the ratio of eating alone at lunch was 54.1%:33.1%, indicating that more than half of the depression group ate alone. In conclusion, it was observed that the nutritional status of allergic disease patients was imbalanced. The nutritional imbalance was due to insufficient energy intake and inadequate intake of nutrients, which was below the average requirements of vitamins and minerals and this was more evident in the depression group than in the non-depression group.
