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.

Antibiotics are frequently administered during pregnancy. Although necessary to address acute infections, their use facilitates antibiotic resistance. Other associations have also been found with the use of antibiotics, such as perturbations of gut bacteria, delays in microbial maturation, and increased risks of allergic and inflammatory diseases. Little is known about how the prenatal and perinatal administration of antibiotics to mothers affects the clinical outcomes of their offspring. A literature search was conducted of the Cochrane, Embase, and PubMed engines. The retrieved articles were reviewed by two authors and verified for relevance. The primary outcome was the effect of pre- and perinatal maternal antibiotic use on clinical outcomes. Thirty-one relevant studies were included in the meta-analysis. Various aspects are discussed, including infections, allergies, obesity, and psychosocial factors. In animal studies, antibiotic intake during pregnancy has been suggested to cause long-term alterations in immune regulation. In humans, associations have been found between antibiotic intake during pregnancy and different types of infections and an increased risk of pediatric infection-related hospitalization. A dose-dependent positive association between pre- and perinatal antibiotic use and asthma severity has been reported in animal and human studies, while positive associations with atopic dermatitis and eczema were reported by human studies. Multiple associations were identified between antibiotic intake and psychological problems in animal studies; however, relevant data from human studies are limited. However, one study reported a positive association with autism spectrum disorders. Multiple animal and human studies reported a positive association between pre- and perinatal antibiotic use by mothers and diseases in their offspring. Our findings have potentially significant clinical relevance, particularly considering the implications for health during infancy and later in life as well as the related economic burden.

Eosinophilic gastrointestinal disease (EGID), a chronic allergic condition characterized by dense infiltration of eosinophils in the digestive tract, is classified into two types, eosinophilic esophagitis (EoE), which features dense infiltration of eosinophils in the esophageal epithelial layer, and eosinophilic gastroenteritis (EGE), in which the entire digestive tract including the esophagus may be involved. Patients with EoE only have esophageal symptoms, since the other parts of the digestive tract are not involved. On the other hand, 80% of EGE patients have lesions in the small intestine. The esophageal epithelial layer in healthy individuals has no or negligible infiltration by eosinophils, while the small intestinal mucosal layer, especially the distal small intestinal mucosa, can show dense eosinophil infiltration even in the absence of disease. Therefore, histological changes observed in cases of EGE are not qualitative but rather quantitative, as compared to EoE, which has qualitative histopathological changes, indicating important pathogenetic differences between the types. Comparisons of clinical, laboratory, and morphological characteristics between EoE and EGE have revealed several interesting differences. Both EoE and EGE patients are frequently affected by atopic diseases, such as bronchial asthma and allergic rhinitis, and elevated plasma levels of Th2 type cytokines and chemokines are also similarly seen in both. On the other hand, age at diagnosis differs, as the former is generally found in individuals from 30 to 50 years old, while the latter appears in all age groups. Additionally, 80% of patients with EoE are male as compared to only 50% of those with EGE. Furthermore, approximately 60% of patients with EoE respond favorably to proton pump inhibitor (PPI) administration, whereas EGE patients rarely show a response to PPIs. Nevertheless, both diseases show a similarly favorable response to a six foods elimination diet and glucocorticoid administration. These similarities and differences of EoE and EGE provide important clues for understanding the pathogenesis of these EGID types.

Objectives : The purpose of this study is to analyze the current trends of various herbal medicine research on allergic disease with dysbiosis. Methods : Electronic searches were performed using Pubmed, Research Information Sharing Service(RISS), Korean studies Information Service System(KISS), Oriental medicine Advanced Searching Integrated System(OASIS). Results : We analyzed ten studies on the effect of herbal medicine on allergic disease with dysbiosis. Eight studies were animal experimental studies, and two were randomized clinical trial(RCT) study and one-group pretest-posttest research, respectively. Among the studies, three studies were on atopic dermatitis, two on allergic rhinitis, and five on asthma. All different herbal medicines were used in the studies. Changes in gut microbiota composition were observed in nine studies except for 1 RCT study. In eight animal experimental studies, there was significant reduction in allergy-related inflammatory markers. Six studies evaluated the change of metabolites related to gut microbiota and three of them showed significant increase in short-chain fatty acids(SCFA). Conclusion : This study provides current trends of studies on herbal medicine research on allergic disease with dysbiosis. Most research is conducted using animal experiments, and this is a relatively recent trend. These studies offer basic knowledge on the correlation between herbal medicine, gut microbiota, and anti-inflammatory effects in allergic disease.

목 적 : 본 연구는 소아, 청소년에게 행해지는 보완대체요법 사용실태에 대한 구체적이고, 다각적인 연구의 필요성이 있었기에 보완대체요법을 접할 기회가 많은 만성질환을 가진 소아, 청소년에서 보완대체요법이 어느 정도 사용되고 있는지, 보완대체요법의 종류에 따른 사용실태를 알아보고, 보완대체요법 사용에 영향을 미치는 인자가 있는지 알아보고자 하였다. 방 법 : 2004년 3월부터 8월까지 관동의대 부속병원 소아과에서 지속적 추적관찰을 해오던 입원 경험이 있는 환아들 중에 만성질환(기관지 천식, 아토피, 간질, 뇌성마비 등)을 앓고 있는 환아(160명)를 대상으로 하였고, 환아와 동행한 보호자에게 설문양식에 따라 면담설문을 실시하였다. 결 과 : 설문 조사에 응답한 만성질환을 앓고 있는 환아는 252명이었고, 그 중 보완대체요법을 시행한 160명(63.5%)을 대상으로 삼았다. 각 질환별 보완대체요법 이용률은 선천성 근병증(100%), 아토피성 피부염(91.1%), 만성 반복성 복통(73.5%), 기관지 천식(72.5%), 만성 설사(50.0%), 뇌성 마비(42.1%), 만성 기관지염(37.5%), 간질(17.1%) 순으로 이용률의 차이를 보였다. 시행한 종류는 식이요법(31.1%), 생약요법(23.4%), 수치요법(16.3%), 마사지(14.2%), 방향요법(8.9%), 침술요법(4.6%), 동종요법(1.3%) 순이었다. 64명(40.0%)이 2가지 이상의 보완대체요법을 동시에 시행하였고, 보완대체요법을 권유받은 경로는 비의사처방에 의한 경우가 133명(83.1%)이었으며, 99명(61.9%)이 보완대체요법의 효과에 대해 긍정적으로 답변했다. 보완대체요법 시행군에 있어서 보완대체요법 사용에 영향을 미치는 인자들 중 부모 연령, 자녀 연령이 통계학적 의의가 있었으며, 부모의 연령이 높을수록 시행경험이 많았고(P=0.001), 자녀의 나이가 어릴수록 보완대체요법을 시행하지 않는 경향을(P=0.002) 보였다. 결 론 : 만성질환을 앓는 환아들은 치료에 있어서 현대의학에 의존하는 반면, 상당수가 보완대체요법을 이용하고 있었으며, 2가지 이상을 동시에 사용하는 경우가 많았고, 그 효과에 대해 긍정적으로 평가하고 있었다. 이와 같은 결과는 국내에서 보완대체요법의 접근성이 용이하고, 긍정적인 측면이 강조되고 있기 때문이므로 무분별한 보완대체요법의 사용을 피하기 위해서는 보완대체요법의 효과와 부작용에 대한 현대의학적인 연구가 더 필요할 것으로 사료된다.

아토피성 피부염은 주로 천식과 비염 등을 동반하는, 주위에서 흔히 볼 수 있는 만성 염증성 피부질환으로 유전학적, 환경적, 면역학적 요인이 복잡하게 연관되어 발병한다. 해수에 포함된 마그녜슘염은 피부에 작용하여 피부장벽을 보호하는 것으로 알려지고 그에 대한 면역학적인 연구와 조직학적 연구는 아직 부족한 실정이다. 이번 연구에서는 피부염을 인위적으로 일으키는 hapten 형성물질인 DNCB를 hairless mice에 도포하여 아토피 피부염 동물 모델로 만든 후, 마그네슘이 다량 함유된 해양 미네랄수를 처리한 후 피부장벽에 미치는 영향을 관찰하였다. DNCB로 피부염을 유발한 hairless mice에 해양미네랄수를 국소적으로 도포하였을 때 유의한 피부수분함량이 증가와 경피수분손실의 감소를 확인하였다 (p<0.01). 피부측정에서 피부거칠기(skin roughness, p<0.05)와 스케일생성(skin scaliness, p<0.01)은 실험군에서 유의한 개선효과를 나타내었으며 조직학적 검사에서도 피부손상지수의 유의한 감소(p<0.01)와 비만세포와(p<0.01) 호산구의 감소(p<0.05) 소견을 보였고 또한 혈청 IgE의 감소를 관찰할 수 있었다(p<0.01). 이상과 같이 마그네슘이 다량 함유된 해양 미네랄수 도포는 피부장벽의 손상을 줄이고 피부수분손실을 효과적으로 줄임으로 아토피성 피부염 증상 유발을 억제할 수 있음을 확인하였다. 현재까지 아토피성 피부염의 관리를 위하여 세라마이드나 식물성 오일의 보습제가 주로 활용되고 있는 상황에서 부가적인 피부장벽의 보호를 위하여 탈염 해양 미네랄수의 활용이 가능할 것으로 판단되며 장기적으로 아토피 피부염 치료의 대체, 혹은 보조적 물질로 활용될 수 있을 것으로 기대된다.

The objective of the study which utilised population based data was to determine the respiratory condition of elementary school children in Gangneung. From October 9th to December 14th, 2006, Pulmonary Function Tests (PFT) including Forced Vital Capacity (FVC) and Forced Expiratoy Volume in I Second $(FEV_1)$ were conducted on the target group of children using a spirometer. The prevalence of asthmatic symptoms was 29.8% among boys and 39.6% among girls. By using logistic regression, we found that family history of allergic rhinitis (OR=3.90, CI=1.05-14.51), experience of allergic conjunctivitis (OR=4.67, CI=1.54-14.16) and atopic dermatitis (OR=2.86, CI=1.17-7.05) significantly increased the asthmatic symptoms. Also, a family history of asthma and food allergy were associated with asthmatic symptoms. In relation to housing and environmental risk factors, residences under the ground (OR=3.59, CI=1.35-9.51) and big-size dolls (OR=2.71, CI=0.86-8.53) significantly increased the prevalence of asthmatic symptoms. For PFT, above four families, exposure of passive smoking and pets significantly reduced FVC in both groups (p<0.05). In girls, a big-size doll was significantly associated with decreased lung function (FVC and $FEV_1$). In boys, using bed significantly reduced $FEV_1$. Also, the risk of asthmatic symptoms was found to increase when the house has been built for 5 years or more, the house is close to a road $({\leq}100m)$, a gas/Kerosene heater or carpet is utilized within the house. However, their differences were not significant. It is concluded that genetic factor such as a family history of respiratory disease, allergic symptoms and housing risk factor are related to asthmatic symptoms. These results were worth noting because the findings will help address risk factors related respiratory symptoms especially in relation to housing and environment.

Background: Allergic diseases like such as atopic dermatitis, asthma, and rhinitis have recently increased both domestically and globally. The present study was undertaken to select candidates with anti-allergic activity from plant resources. Methods and Results: Fifty-six plant extracts at $20{\mu}g/m{\ell}$ were screened against ${\beta}$-hexosaminidase production and interleukin (IL)-4 release in degranulated rat basophilic leukemia (RBL)-2H3 cells. The anti-allergy activity of three plant extracts selected from the preliminary screening experiment, Polygonatum sibiricum F. Delaroche (root), Pyrus pytifolia var. culta (Makino) Nakai (leaf), and Rehmannia glutinosa (Gaertn.) Libosch. ex Steud (root) were measured at concentrations of $2-250{\mu}g/m{\ell}$ in three cell lines as RBL-2H3, HaCaT and Jurkcat T cells. The assay showed the root extract of R. glutinosa to have an inhibitory activity of 4.2% - 28.6% on ${\beta}$-hexosaminidase production from IgE-sensitized RBL-2H3 cells. Each extract of P. sibiricum and R. glutinosa reduced IL-4 release in IgE-sensitized RBL-2H3 cells, respectively. The leaf extract of P. pyrifolia var. culta showed a significantly potent suppressive effect of 10.2% - 74.7% on the mRNA expression of tumor necrosis factor (TNF)-${\alpha}$ in HaCaT cells sensitized with TNF-a and INF-g, and showed inhibitory effect of -8.6% - 90.9% on the mRNA expression of IL-2 in Jurkat T cells sensitized with PMA and A23187. Conclusions: The results showed that the root of R. glutinosa and leaf of P. pyrifolia var. culta could be useful candidates as antiallergy materials.

Objectives: Exposure to bioaerosols in the indoor environment could be associated with a variety adverse health effects, including allergic disease such atopy. The objectives of this study were to assess children's exposure to bioaerosol in home indoor environments and to evaluate the association between atopy and bioaerosol, environmental, and social factors in Ulsan, Korea. Methods: Samples of viable airborne bacteria and fungi were collected by impaction onto agar plates using a Quick Take TM 30 and were counted as colony forming units per cubic meter of air (CFU/$m^3$). Bioaerosols were identified using standard microbial techniques by differential stains and/or microscopy. The environmental factors and possible causes of atopy based on ISAAC (International Study of Allergy and Asthma in Childhood) were collected by questionnaire. Results: The bioaerosol concentrations in indoor environments showed log-normal distribution (p < 0.01). Geometric mean (GM) and geometric standard deviation (GSD) of airborne bacteria and fungi in homes were 189.0 (2.5), 346.1(2.0) CFU/$m^3$, respectively. Indoor fungal levels were significantly higher than those of bacteria (p < 0.001). The concentration of airborne bacteria exceeded the limit recommended by the Korean Ministry of Environment, 800 CFU/$m^3$, in three out of 92 samples (3.3%) from 52 homes. The means of indoor to outdoor ratio (I/O) for airborne bacteria and fungi were 8.15 and 1.13, respectively. The source of airborne bacteria was not outdoors but indoors. GM of airborne bacteria and fungi were 217.6, 291.8 CFU/$m^3$ in the case's home and 162.0, 415.2 CFU/$m^3$ in the control's home respectively. The difference in fungal distributions between case and control were significant (p = 0.004) and the odds ratio was 0.996 (p = 0.027). Atopy was significantly associated with type of house (odds ratio = 1.723, p = 0.047) and income (odds ratio = 1.891, p = 0.041). Some of the potential allergic fungal genera isolated in homes were Cladosporium spp., Botrytis spp., Aspergillus spp., Penicillium spp., and Alternatia spp. Conclusions: These results suggest that there this should be either 'was little' meaning 'basically no significant association was found' or 'was a small negative' mean that an association was found but it was minor. It's a very improtant distinction. Association between airborne fungal concentrations and atopy and certain socioeconomic factors may affect the prevalence of childhood atopy.
