Purpose: To examine the prevalence and clinical manifestations of eosinophilic esophagitis (EoE) in Korea children. Methods: The study was designed as a 1:2 matching case-control study. Using information from the endoscopic database of a tertiary center, we retrospectively reviewed the medical records of patients aged 18 years or younger who underwent upper gastrointestinal endoscopy between January 2014 and December 2017. A total of 21 patients were diagnosed with EoE based on current diagnostic criteria. In addition, 42 controls with normal esophageal biopsy findings matched to each EoE case by sex, age (±1 months), and season were randomly selected during the study period. Results: The mean age of EoE diagnosis was 12.1±4.0 years and the male-to-female ratio was 2:1. The proportion of allergic diseases in patients with EoE (28.6%) was higher than that in the controls (6.8%) (p=0.04). Most EoE patients tested for allergy were positive for at least one antigen, which was significantly different to the controls (88.2% vs. 47.4%, p=0.01). Characteristic endoscopic findings of EoE were noted in 19 patients (90.5%), but 2 patients (9.5%) showed normal esophageal mucosa. The clinical symptoms of EoE were improved by a proton-pump inhibitor in 10 patients (50.0%), and by an H2 blocker in 9 patients (45.0%). Only one patient (5.0%) required inhaled steroids. Conclusion: While EoE is rare in the Korean pediatric population, the results of this study will improve our understanding of the clinical manifestations of the disease.
Bovine lactoferrin is well known as biological activator in defense mechanism related some cells. In this study, we was investigated about the immune modulator as a role of lactoferrin through the transcriptional regulation of genes associated with hypersensitivity such as allergy, athma and inflammatory disease. Effects of inflammatory reaction of bovine lactoferrin was carried out by RT-PCR analysis from isolated total RNA treated with lactoferrin 0, 10, 50, 100, 500 ${\mu}g/mL$ and PMA 100 ng/mL. The expression of the TYROBP, PITPNA, IL-10, SLP1, DC-stamp and ICAM-1 mRNA were increased by synergy effect of bovine lactoferrin and PMA. The results of RT-PCR showed that bovine lactoferrin and PMA had an effect of immune modulator by enhancement of TYROBP, PITPNA, SLP1, DC-stamp, IL-10 and ICAM-1 gene transcription in U937, Mutz-3 and NK92 cells, respectively. Bovine lactoferrin showed a potential of biological function which could be used for industrial applications as a material of food and pharmaceutical.
The dried unripe fruit of Poncirus trifoliata L. is widely used to treat urticaria, itch and indigestion in folk medicine. And recently it was reported the component of the fruit was found to exhibit an inhibitory effect on histamine release from mast cells. So to evaluate the effect of aqueous extract of Poncirus trifoliata L.(PTFE) on compound 48/80-induced histamine release, the study was carried out in rat peritoneal mast cell. PTFE $(10^{-3}{\sim}1mg/ml)$ inhibits the histamine release induced by compound 48/80 $(5{\mu}g/ml)$ in rat peritoneal mast cells. To clarify the mechanism of these inhibition, we investigated the effect of PTFE on cAMP and intracellular calcium content. The increase in cAMP content, when PTFE was added, was transient. At concentration of 1mg/ml, the cAMP content of mast cells was significantly increased at a rate of 53 times of basal cells at 10sec. PTFE inhibits histamine release by augmenting the cAMP content in mast cells. Moreover, PTFE inhibits intracellular calcium release induced by compound 48/80. This result suggests that PTFE may be useful for the prevention and treatment of allergy-related disease.
Background: Nasal polyps are benign mass of nasal mucose, chronic sinusitis are swelling of nasal mucose, so nasal polyps and chronic sinusitis take a place at the same time. Nasal polyps are located lateral wall of nose, middle meatus, between middle nasal concha and inferior nasal concha. Objective: To demonstrate the effect of herbal medicine therapy in the chronic sinusitis and nasal polyps before and after treatment using computed tomography (CT). To compared before and after treatment of otitis media using earscope. Materials and methods: Five patients (4 mail and 1 femail) treated in our hospital between August 1998 and July 1999 were studied. Ages ranged from 9 to 23 years (mean age:13 years). All patients had a underlying family history, and past history(allergy or sinusitis of parents or brothers). Illness period was from 1 to 36 months (mean period:10.5 month). To ascertain the efficacy of treatment, CT were checked out. In the CT, three images were obtained 2cm interval on the coronal and axial plan. We classified treatment period into the type of allergic disease. Gamihyunggyeyungyo-tang was administered mainly. Gamigwaghyangjeungki-san, Gamizwakwi-eum and Gamihyangso-san were administered for through oral route additional symptoms. Results: Treatment period was from 126 to 157 days (mean period:140.7 days). To 3 patients with chronic sinusitis and nasal polyp, treatment period was 140.7 days, to 2 patients with otitis media and chronic sinusitis and nasal polyp, treatment period was 141.5 days. So they had no significance. Not nasal polyp from middle meatus, but also polypoid mucosal change of maxillary sinus is polyps Conclusion: We know that herbal medicine therapy is the effective treatment of pediatric chronic sinusitis and otitis media using earscope and CT. Herbal medicine therapy was effective in increasing immunity, inhibiting allergic reaction and inflammation of respiratory system. we practice ECP(eosinophil cataionic protein) and MAST examination, objectify herbal medicine therapy.
The purpose of this study was to identify the influence of living factors on TVOC(Total Volatile Organic Compounds) concentrations and personal factors to reduce the Sick House Syndrome for newly-built apartments. The field measurements of TVOC concentrations were made totally 30 times(5 times per one subject house) in six apartment units in which residents recently moved. Those apartments authorized its business approval before May 2004, the Act of Indoor Air Quality Management for multi-use facilities. The Questionnaire surveys of residents' subjective responses on the Sick House Syndrome were carried out in 2nd measurement of each house. Respondents consisted of 20 residents living in the measured houses. The findings were as follows: The TVOC concentrations of the measured subject apartments ranged from about 1/10 of the recommended standard for multi-use facilities($400{\mu}g/m^3$) to up to 90 times as high as the standard. Since then, the Recommended Standard of Indoor Air Quality Management for newly-built apartment house was announced in December 2005. In accordance with this standard($2390{\mu}g/m^3$) it ranged from about 1/100 to up to 15 times as high as the standard. The subject house whose TVOC concentrations reduced below the recommendation standard in the shortest period had the largest amount of ventilation (all the windows were open for ventilation in the past three months) among all measured houses. The reason of another house whose TVOC concentrations were much higher than the rest was fronted with new furniture in the room. There turned out to be no apparent relations between the TVOC concentrations and the residents' individual responses of Sick House Syndrome. The responses were serious in those who stayed in their new houses for a long period or had disease like allergy. It's recommended that they should open all the windows for at least three months for ventilation in newly-built houses, and it would be better to avoid remodeling than needs be.
Asthma is an inflammatory airways disease characterized by bronchial hyperresponsiveness and airways obstruction, which results from a complex interaction of genetic and environmental factors. Interleukin (IL)-13 and IL-4 are important in IgE synthesis and allergic inflammation, therefore genes encoding IL-13 and IL-4 are candidates for predisposition to asthma. In the present study, we screened single-nucleotide polymorphisms (SNPs) in IL-13 and IL-4 and examined whether they are risk factors for asthma. We resequenced all exons and the promoter region in 12 asthma patients and 12 normal controls, and identified 18 SNPs including 2 novel SNPs. The linkage disequilibrium(LD) pattern was evaluated with 16 common SNPs, and haplotypes were also estimated within the block. Although IL-13 and IL-4 are localized within 27 kb on chromosome 5q31 and share many biological profiles, this region was partitioned into 2 blocks. One SNP and three SNPs were determined as haplotype-taggingSNPs (htSNPs) within IL-13 and IL-4 haplotype-block, respectively. No significant associations were observed between any of the SNPs or haplotypes and development of asthma in small number of Korean subjects. However, the genetic variants of IL-13 and IL-4 would provide valuable strategies for the genotyping studies in large population.

The most common local cause of active gingival bleeding is the vessel engorgement and erosion by severe inflammation. Abnormal gingival bleeding is also associated with the systemic disturbances. Hemorrhagic disorders in which abnormal gingival bleeding is encountered include the following: vascular abnormalities (vitamin C deficiency or allergy), platelet disorders, hypoprothrombinemia (vitamin K deficiency resulting from liver disease), and other coagulation defects (hemophilia, leukemia). There are many conventional methods for gingival bleeding control, such as, direct pressure, electrocoagulation, direct suture, drainage, application of hemostatic agents and crushing and packing. If the active continuous gingival bleeding is not stopped in spite of the application of all conventional bleeding control methods, the life of patient is threatened owing to upper airway obstruction, syncope, vomiting and hypovolemic shock. Therefore, the rapid and correct hemostatic method is very important in the emergency dental care. This is a case report of active gingival bleeding care via dental crown removal and emergency primary endodontic drainage as a last method in liver cirrhosis patient with advanced periodontitis.
The prevalence of Atopic Dermatitis (AD), a non-infective chronic inflammatory skin disease, is increasing worldwide. Avoiding the allergen is the basic principle in the treatment of AD. However, when the allergen is food, excessive restriction can lead to nutrition deficiency. The objective of the study was to examine the status of the dietary restriction and compare the caregiver's restriction practice with doctor's recommendation in Korean children with AD. A total of 158 children diagnosed with Atopic Dermatitis were recruited for this study. Information about foods that aggravate AD symptoms and food restriction were collected from the mothers of 158 children aged 6 month-5 year with AD using questionnaires. Food restriction recommendation by doctor was collected through medical chart. McNemar and Margianl homogeneity tests were used to detect a relationship between food restriction recommended by doctor and current practice by mother. There were significant proportion differences of food restriction for each food between by doctor and mother. We found 75.9% of children were avoiding eggs although only 61.4% were recommended for egg restriction by a doctor. Children with restriction of more than 4 kinds of food were 53.2% compared to 13.3% by doctor. Excessive restrictors tended to be younger and diagnosed at younger age. The caregivers of excessive restrictors had trends of "being older" and "having higher income". Avoidance of common foods in children without food allergy could result in malnutrition or impaired growth. Nutrition education is needed for sound practice and nutrition care in children with Atopic Dermatitis as well as interactive communication between caregivers and experts.

Herbal mixture water extract of (Chrysanthemum morifolium, Portulaca oleracea, Sanguisorba officinalis, Sophora flavescens, Phellodendron amurense, Cnidium monnieri) which exhibit several beneficial effects including acne and skin diseases, was tested for anti-microbial activity and anti-inflammation effects. The herbal mixture extract showed antimicrobial activity against Stapylococcus epidermis, and Propionibacterium acne. The growth of Stapylococcus epidermis, and Propionibacterium acne was inhibited completely by addition of 1.0% of the extract. Also in the present study we examined the mixture extract on compound 48/80 induced allergy and LPS induced cyclooxygenase-2(COX-2) gene expression in RAW 264.7 macrophage. The results indicated the ear swelling and histamine release induced by compound 48/80 were dose-dependently reduced, ranging 28-60%, and 48-72% , respectively. Furthermore the extract inhibited the expression of LPS-induced COX-2 proteins and mRNAs without an appreciable cytotoxic effects on RAW 264.7 cells. The LPS-induced cytokine gene expression including IL-$1{\beta}$, TNF-$\alpha$, and IL-6 were dose-dependently suppressed by the mixture extract. Based on these results, it is concluded that the herbal mixture water extract can be applied to the acne and skin diseases therapy.
Cluster of differentiation 1 (CD1) is a family of cell-surface glycoproteins that present lipid antigens to T cells. Humans have five CD1 isoforms. CD1a is distinguished by the small volume of its antigen-binding groove and its stunted A' pocket, its high and exclusive expression on Langerhans cells, and its localization in the early endosomal and recycling intracellular trafficking compartments. Its ligands originate from self or foreign sources. There are three modes by which the T-cell receptors of CD1a-restricted T cells interact with the CD1a:lipid complex: they bind to both the CD1a surface and the antigen or to only CD1a itself, which activates the T cell, or they are unable to bind because of bulky motifs protruding from the antigen-binding groove, which might inhibit autoreactive T-cell activation. Recently, several studies have shown that by producing TH2 or TH17 cytokines, CD1a-restricted T cells contribute to inflammatory skin disorders, including atopic dermatitis, psoriasis, allergic contact dermatitis, and wasp/bee venom allergy. They may also participate in other diseases, including pulmonary disorders and cancer, because CD1a-expressing dendritic cells are also located in non-skin tissues. In this mini-review, we discuss the current knowledge regarding the biology of CD1a-reactive T cells and their potential roles in disease.
