Purpose: The use of soy-based infant formula has increased widely in infants with cow's milk allergy (CMA). This study aimed to provide evidence on the growth pattern of CMA infants fed with soy-based infant formula in an Indonesian setting. Methods: A multi-site, intervention study was conducted among full-term and normal birth weight CMA infants. Within six months, the subjects were provided with a soy-based infant formula. Weight, height, and head circumference were measured at baseline, weeks 4, 8, 12, 16, 20, and 24. Adverse events were recorded by scoring atopic dermatitis and symptom-based clinical scores. Results: Based on the World Health Organization growth chart, we found that most of subjects had normal nutritional status for weight-for-age, length-for-age, weight-for-length, and head-circumference-for-age. There were statistically significant differences between baseline and end-line for weight-for-age, length-for-age, weight-for-length, and head circumference-for-age nutritional status. No allergic symptoms or intolerance toward soy formula were observed at the end of the intervention period. Conclusion: These results show that infants fed with soy-based infant formula have a normal pattern of growth.

Objectives : Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by eczematous inflammtion of the skin. The chestnut inner shell extracts (CI) has been used as a cosmetic material for a long time in Korea. However, the precise anti-allergy effects of CI have yet to be clearly elucidated. In this study, we attempted to evaluate the effect of CI on mast cell-mediated allergy inflammation. Methods : To find the anti-allergy and inflammatory effect of CI, we investigated the inhibitory effect of CI on the production of inflammatory mediators using by enzyme-linked immunosorbent assay in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore (A23187) stimulated-human mast cell (HMC-1). Results : In this study, we found that CI did not show cytotoxic effect at up to 10 ug/ml on HMC-1. CI inhibited the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6 and IL-8 in stimulated HMC-1. Maximal rate of TNF-${\alpha}$, IL-6 and IL-8 inhibition by CI (10 ug/ml) were about 47.6%, 44.1% and 22.5% respectively. In addition, we showed that Fr.3 isolated from n-Butyl alcohol layer of CI attenuated the production of TNF-${\alpha}$, IL-6 and IL-8 in HMC-1. Conclusion : Taken together, the findings of this study provide us with a novel insight action of CI as a potential molecule for use in the treatment of allergic inflammation diseases.

Objectives : Cudrania tricuspidata (C. tricuspidata) is well-known traditional herbal remedy and its root, leaf and fruit were used for treatment of inflammation, tumor and painkilling. However, effect of C. tricuspidata fruit on tight junction is still unknown. The aim of this research was to determine the effect of C. tricuspidata fruit extract on human keratinocyte HaCaT cells. Methods : The antioxidant effects of water extract of C. tricuspidata (WECT) and ethanol extract of C. tricuspidata (EECT) were analyzed by using an ABTS assay. To confirm the cytotoxicity of WECT and EECT, MTS assay was performed. The mRNA expression levels of tight junction related genes were analyzed using quantitative RT-PCR analysis. Furthermore, dispase assay was used to investigate the alteration of cell-cell adhesion strength of EECT treated HaCaT cells. Results : WECT and EECT showed strong antioxidant activity. No obvious cytotoxicity was observed in both WECT and EECT until $2.0mg/m{\ell}$ concentration. The mRNA expression level of Claudin 6 were significantly increased by EECT treatment, whereas the WECT did not affect the expression of Claudin 6. Furthermore, EECT treatment enhances cell-cell adhesion strength. Conclusions : In this study, we investigated the physiological activities of the extracts of Cudrania tricuspidata fruit extracts on human keratinocytes by two different extraction methods. EECT might have an anti-aging activity on the skin by reducing oxidative stress. Moreover, it may be a useful ingredient in atopic dermatitis and skin-moisturizing, given its effects of altering Claudin 6 gene expression and enhancing cell-cell adhesion strength.

Purpose: Data on eosinophilic esophagitis (EoE) in South America is scarce. Moreover, no studies are available in Ecuador. We evaluated the clinical, endoscopic, and histological characteristics of Ecuadorian children with EoE. Methods: Medical records of 2,711 children who underwent upper gastrointestinal endoscopy (UGE) between 2009 and 2020 at Hospital Metropolitano de Quito, Ecuador were reviewed. Esophageal mucosal biopsies were obtained from 72 patients and the features of 35 children with EoE were described. EoE was diagnosed when there were more than 15 eosinophils in the esophagus, per high power field. Results: EoE was diagnosed in 35 children (9.4±4.5 years) with a male predominance (74%). Abdominal pain (51.4%) and vomiting (31.4%) were dominant symptoms. A history of allergic diseases was noted in 47.1% of the children, which mainly included allergic rhinitis (37.1%) and atopic dermatitis (11.4%). The most common endoscopic findings were furrowing (82.9%) and edema (74.3%). All patients were initially treated with proton-pump inhibitors (PPIs). Those who did not respond to PPIs received steroids (5.7%) and diet therapy (5.7%), and five patients were referred to an allergist. Clinical and histological resolution was observed in 65% of the patients who underwent a second UGE after 6-8 weeks of PPI. Conclusion: Our study describes the clinical features of pediatric EoE in Ecuador. This is the first retrospective study in Ecuador that describes the clinical, endoscopic, and histological manifestations of EoE in a small pediatric population. Almost half of the children who underwent a biopsy had EoE.

In this study, we assessed anti-oxidant activity, anti-microbial, inhibition of biofilm formation and inflammatory factors(nitric oxide, interleukin-6, interleukin-8) inhibitory effect of Perillae semen hydrothermal extract(PSW) and three kinds of Perillae semen supercritical fluid extract(PSSs) extracted by controlling temperature with no variation of pressure. Compared with PSW, PSSs had significantly lower minimal inhibitory concentrations(MICs) against Staphylococcus aureus(S. aureus) and the ability of PSSs to inhibit formation of biofilm was also superior. PSSs reduce the production of inflammatory mediator and inflammatory cytokines significantly compared to PSW. We suggest, therefore, Perillae semen supercritical fluid 45℃ extract which showed the best anti-microbial, inhibition of biofilm formation, and inhibition of inflammatory factors production among the supercritical fluid extracts could be used for protecting patients with atopic dermatitis from pruritus and transepidermal water loss as a functional ingredient from nature.

In this study, oregano was extracted by supercritical extraction and hydrothermal extraction method. In vitro experiments such as antimicrobial and antioxidant activity test were performed. As a result of the disc diffusion method, only the supercritical extracts formed a clear zone. The MIC for S. aureus was found only in the supercritical fluid extracts and it was 1000 ㎍/mL. The hydrothermal extract's MIC is 125 ㎍/mL for C. acnes. Through biofilm inhibition assay, we found that the supercritical fluid oregano extracts inhibit the biofilm of S. aureus by more than 70% even at low concentrations of 125 ㎍/mL. On the other hand, the antioxidant ability of the hydrothermal extract was better than that of the supercritical fluid extracts. Furthermore, we tried to make a skincare ingredient for atopic dermatitis by utilizing the S. aureus biofilm inhibitory ability of oregano supercritical fluid extracts. Liposome was used to overcome the low solubility of the oregano supercritical fluid extracts and increase stability.

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.

The purpose of this study was to identify the influencing factors of Korean adolescents' consumption of convenience foods based on a bio-psycho-social model. Data were obtained from the 15th (2019) Korea Youth Risk Behavior Survey, which involved a nationwide representative sample of 57,303 middle- and high-school students. As a result of the study, gender, grade, and atopic dermatitis were biological factors of convenience food intake in adolescents. The psychological factors were perceived stress level, experience of depression, suicidal ideation, subjective sleep sufficiency, perceived health status, physical activity, and current smoking and drinking. And nutrition and meal education, breakfast frequency, subjective academic achievement, subjective economic status, and family living together were sociological factors that affected adolescents' convenience food intake experience. Therefore, it is necessary to provide effective nutrition education programs and provide emotional support to manage healthy eating habits of adolescents. In addition, family members of adolescents should be included in education.
