  • 경남 산청지방에서 쏘가리를 양식하던 어장에서 대량폐사가 발생하였다. 주요 증상으로 전신 피부에서 궤양이 진행되었고 조직학적으로는 주요 실질 장기에서 세균의 집락과 주변부위로 염증 및 괴사가 관찰되었다. 분리된 세균을 API 20E 및 API 20NE를 이용하여 생화학적 검사를 실시한 결과 Aeromonas salmonicida subsp. salmonicida (typical A. salmonicida)로 진단할 수 있었다. 그러나 atypical A. salmonicida와 typical A. salmonicida로 구분할 수 있는 PCR 기법을 실시한 결과, 본 세균은 atypical A. salmonicida임을 확인할 수 있었다. 본 연구는 우리나라 쏘가리에서 A. salmonicida로 인한 발병의 최초 보고임과 동시에, A. salmonicida의 정확한 진단을 위해선 생화학적 검사가 아닌 PCR 검사를 이용한 진단을 실시해야 함을 제시하였다.

  • 유기농 및 일반재배 대두를 다양한 용매에서 추출하여 그 추출물에 대한 항산화 효과, 항염증 효과, 대식세포의 세포사멸 보호 효과, 그리고 알레르기 저해효과를 비교하였다. DPPH 법과 SOD 효소의 활성 측정으로 항산화 능력을 평가하였으며, 항염증 효과는 LPS로 유도시킨 Raw 264.7 세포주에서 염증 매개 단백질인 Cox-2와 iNOS의 발현량을 western blotting으로 조사하여 분석하였다. 또한 대식세포 보호 효과를 세포사멸 조절 단백질인 Bcl-xl의 발현량 조사로 평가하였고, 1 mM $H_2O_2$ 처리로 유도되는 세포사멸의 보호효과를 세포 수 측정법으로 조사하였다. 항알레르기 효과는 흰쥐의 비만세포인 RBL-2H3 세포주를 사용하여 IgE로 매개되는 비만세포의 탈과립화를 OPT assay로 측정하여 분석하였다. 그 결과, 일반 재배보다 유기 재배 대두 추출물이 더 좋은 항산화, 세포사멸 보호, 항염증 효과를 나타내었다. 특히 유기농 대두의 열수 추출물은 LPS로 유도시킨 염증반응을 효과적으로 억제하는 것으로 나타났다. 그러나 항알레르기 효과는 모든 추출물에서 히스타민 유리량이 약간 감소하는 것으로 나타나 유기농과 일반재배의 차이를 확인할 수 없었다. 대두에는 많은 유용한 생리활성물질 뿐 만 아니라 알레르기 유발 물질도 존재하는 것으로 알려져 있지만 조추출물 상태에서는 특이적인 알레르기 유발보다 오히려 항알레르기 효과가 나타났다. 결론적으로, 만성 염증 및 천식, 그리고 아토피피부염과 같은 염증관련 질환에는 유기재배된 대두가 일반 대두보다 좋은 억제 효과를 가지고 있다고 판단된다.

  • Background : Although the pathophysiology of asthma has been reported, its mechanism has not been fully elucidated. The mast cell is an effector cells in allergic inflammation and secretes a number of chemokines. Chemokines are important for the recruitment of leukocytes to sites of infection, which is essential in host defense. Chemokines also contribute to the pathogenesis of several disorders such as asthma, chronic bronchitis, atopic dermatitis, allergic rhinitis, and rheumatoid arthritis. Objective : In this study, the aim was to identify the effect of Baekryunchihyo-tang(白蓮治哮湯) on expression of chemokines. This was examined by RT-PCR using the human mast cell line (HMC-l) Materials and Methods : HMC-l cells were used, which is known to secrete and express chemokines. In order to investigate the protective effect of Baekryunchihyo-tang(白蓮治哮湯), HMC-l cells were incubated with pretreatment of Baekryunchihyo-tang(白蓮治哮湯) for 24 hrs. RT-PCR analyses of chemokine genes of cells pretreated with Baekryunchihyo-tang(白蓮治哮湯) showed that expressions of IL-8, $MIP-l{\beta}$, and RANTES genes in these cells were lower and $MIP-l{\alpha}$ showed a similar pattern compared to the calcium ionophore-treated group. In addition, cell cytotoxicity concentration measurements were performed by MTT assay method. Results : After stimulation with 1 uM calcium ionophore A23178 for 2 hrs, IL-8, major one of CXC chemokines, was highly expressed, and expression of $MIP-l{\beta}$ and RANTES (CC chemokines) increased, while expression of $MIP-l{\alpha}$ did not change. The cell cytotoxicity of Baekryunchihyo-tang(白蓮治哮湯) with treatments at various concentrations and times was not observed, respectively. Conclusion : This study suggests that Baekryunchihyo-tang(白蓮治哮湯) has dose-dependent effects on mRNA expression of IL-8(CXC chemokines), $MIP-l{\beta}$ and RANTES(CC chemokines) in human mast cellline(HMC-l). So these herbal medicines may inhibit the inflammatory process of asthma. Advanced studies are required to investigate the mechanism of inhibition by herbal medicine in the asthma model. This study provides basic data on the possibility of the clinical treatment of Baekryunchihyo-tang(白蓮治哮湯) for allergic disorders.

  • Purpose: The aim of the present study was to investigate the clinical features and outcome of eosinophilic gastroenteritis (EGE) in children. Methods: Our study enrolled 24 children who were diagnosed with EGE from 1993 to 2014 at the Department of Pediatrics, Seoul National University Children's Hospital. The patients' clinical manifestations, treatments, and outcomes were reviewed from the medical records. Results: The mean age at diagnosis was 5.3 years. Most patients had gastrointestinal symptoms including diarrhea (54.2%) and abdominal pain (45.8%). Peripheral eosinophilia was present in 91.7% of the patients. Thirteen patients (54.2%) showed anemia, and 15 patients (62.5%) had hypoalbuminemia. EGE was classified as mucosal, subserosal, or muscular in 75.0%, 20.8%, and 4.2% of cases, respectively. Three patients showed gastroduodenal ulcers upon endoscopic analysis. A history of allergy was reported in 13 patients, including atopic dermatitis, allergic rhinitis, and asthma. Five patients (20.8%) improved with food restrictions. Among the 19 patients treated with steroids, 11 (57.9%) discontinued steroid treatment without subsequent relapse, 4 (21.1%) relapsed after ceasing steroid treatment, and 4 (21.1%) showed no response to steroids. Two patients who were resistant to steroids underwent therapeutic surgery. The presence of gastroduodenal ulcers was significantly associated with relapse and steroid resistance. Conclusion: A high suspicion of EGE is warranted when children have nonspecific gastrointestinal symptoms and peripheral eosinophilia. Most patients improved with food restrictions or steroid treatment, although one-third of patients showed a relapse or steroid resistance.

  • The purpose of this study was to evaluate the general features of allergic patients in northwestern Chungcheongnamdo who visited Soonchunhyang University Cheonan Hospital. The subjects in this study were 1692 suspected allergic patients. After their allergic symptoms were checked and a MAST-CLA test was conducted, the following results were obtained: 1. The mean age of the subjects was 23.1 years old. The male patients represented 56.2% and the female patients accounted for 43.8%. 1387 (82.0%) patients of those investigated suffered from allergic disease. 2. Among the 1387 patients, 1022 (73.7%) patients showed an increased total IgE level. The positive rate of those who were in their 40s (87.0%) was the highest, but their age made no difference to their positive rate of total IgE. 3. Concerning the positive rate for allergen specific antibody by age, those who were in their teens (73.5%) topped the list and similar in all age group except in their 40s. By gender, the positive rate of the male and female were 56.3% and 43.9% respectively. Regarding the positive rates by allergic disease, those who suffered from allergic rhinitis (60.4%) were most vulnerable, followed by the patients with allergic dermatitis (47.4%), with bronchial asthma (47.2%) and with urticaria (39.4%). 4. As for seasonal positive rates, they were most susceptible in April (77.2%) and May (71.1%). We discovered a significant difference according to seasons; Spring (60.1%), Winter (45.4%) and Summer (39.2%). 5. In case of Korean inhalent panel, the most dominant allergen-specific antibodies were "Cockroach mix" (31.1%), followed by "D. pteronyssius" (23.8%) and "Dog" (14.3%). In the event of food panel, the most popular allergen-specific antibodies were "D. farinae" (25.0%), followed by "D. pteronyssinus" (19.8%) and "Hose dust" (12.0%). 6. The residential type made no difference to the positive rates of "House dust", "Cockroach mix" and "Dog" as major antigen but compared with others, positive rates for "Tick" were somewhat higher in apartment buildings.

  • Background and Objectives: Subacute necrotizing lymphadenitis or Kikuchi's disease has now become recognized in many parts of the world as a well-defined clinicopathologic entity. It typically affects cervical lymph nodes of young women, and subsides spontaneously within a few months without recurrences. The purpose of this study is to report the clinicopathologic finding, radiologic finding and many laboratory tests to elaborate the criteria that are useful in distinguishing this entity from inflammatory disease, granulomatous disease, lymphoma, malignant disease. Material and Methods: Authors evaluated 22 patients, who were diagnosed as subacute necrotizing lymphadenitis on excisional biopsy or fine needle aspiration cytology with retrospective chart review. Results: The patient population consisted of 21 women and 1 men. The mean age was 25 years old(range 17 to 42 years). All patient had palpable neck mass and associated fever, headache, weight loss, otalgia, diarrhea, night sweating. and associated disorder is dermatitis, hepatitis B, SLE, Hashimoto's thyroiditis, albinism et al. The multiple bilateral involvement of cervical lymph node was 20 cases(91%) and multiple unilateral 18 cases(82%), multiple bilateral 2 cases(9%). Solitary involvement was 2 cases(9%), mean size of involved lymph node was 2.0cm. In laboratory tests, leukopenia 17 cases(72%), elevated ESR 12 cases(54%), elevated GOT, GPT 3 cases(13%). In CT finding, lymph nodes enhanced in homogeneous fashion, and there was no evidence of central necrosis. Conclusion: Subacute necrotizing lymphadenitis, Kikuchi's disease may be easily confused clinically, pathologically, radiologically with malignant lymphoma, inflammatory disease, granulomatous disease. We should consider open biopsy of lymph node in the patient which had unilateral multiple cervical lymph node and in laboratory tests, were leukopenia, elevated ESR, especially in young women. otherwise, result of fine needle aspiration biopsy is nonspecific, excisional biopsy is recommended in order to differentiate other disease.

  • 수세미오이(Luffa cynlindrica)는 박과 채소작물로 우리나라에서는 주로 관상용으로 재배되어 왔다. 그러나 최근에는 미용소재, 한방약재, 건강보조용 등으로 수요가 증가하면서 재배면적이 증가하고 있다. 따라서 본 실험은 수세미오이의 기능성을 구명하기 위하여 재래종 수세미오이를 사용하여 수액의 무기성분을 분석하고 수액과 식물체 부위별 항산화 효소 활성과 항균활성을 측정하였다. 수세미오이 수액은 K, Ca, P, Mg이 주요 성분이었으며, K의 함량이 $470mg{\cdot}L^{-1}$으로 가장 높았다. Ca과 Mg의 함량은 오이의 약 2배와 1.7배로 높게 나타났다. 수세미오이의 조직별 항산화효소 활성을 분석한 결과 전체적으로 APX 활성이 CAT와 SOD 활성보다 높았다. 식물체 부위별로 비교해 볼 때 항산화효소 활성은 잎, 뿌리, 꽃, 과실, 종자, 수액보다 줄기에서 가장 낮게 나타났다. 수세미오이 수액의 식품유해균 10종에 대한 항균 활성은 Vibrio parahaemdyticus와 Propionibacterium acne에 대하여 미미한 활성을 보였을 뿐 그 외 8종의 균에 대해서는 효과가 없었다. 피부염 등 인체 감염을 일으키는 Candida albicans와 Malassezia furfur에 대한 수세미오이의 부위별 항균활성 분석 결과, 수액의 항균활성이 식물체의 다른 부위보다 높게 나타났다. 전체적으로 Malassezia furfur에 대한 항균활성이 Candida albicans에 대한 항균활성보다 높은 것으로 나타났다.
