PURPOSE: Right middle lobe symdrome is characterized by a spectrum of disease from recurrent atelectasis and pneunomitis to brobchiectasis of the Right middle lobe symdrom. It was first reported gy Grahm describing 12 patients with middle loge atelectasis and bronchiectasis due to enlarged lymph nodes. The incidence of Right middle lobe syndome seems tobe increasing in children, byt there have been only a few studies of right middlelobe syndrome in Korea. METHODS: Twenty-five children with RMLS who had been admitted during the last 10 years were evaluated with particular attention to clinical features, laboratory results, bronchographic findings, and treatment RESULTS: All patients were symptomatic and complained of chronic cough(25), sputum(20), fever(16), dyspnea(3), vomiting(2), and foreign body in the bronchus(2). Most of the patients had recurrent pneumonia: 6 patients had Mycoplasma pneumonia, and 6 patients had ashma and allergic disorders. Only 5 out of the 25 patients showed sufficient obstruction on bronchography and 6 patients took computed tomography scans. Chest radiography, bronchography and computed tomography scans were evaluated for review in 25 patients showing consolidation(17), patchy infiltration(14), atelectasis(12), hyperinflation(5), bronchiectasis(2), and air bronchogram(2). Most patients were improved by conservative medical management and only 2 patients had closed thoracostomy. CONCLUSION: These 25 patients who had been diagnosed as Right middle lobe syndrome were improved after 2 week treatment of antibiotics and conservative management and their prognosis were good during the follow-up period.

PURPOSE: A Cow's milk allergy (CMA) is one of common problems during first year of life. Though milk caused allergic problems, their parents didn't know it, and gave milk to their children. But the parents don't give milk to their children if they know it. Therefore it may cause problems of growth and development in children. The purpose of this study is to analyze those clinical features of milk allergy confirmed by oral provocation test. METHODS: We carried out the retrospective study on 21 patients who had been performed oral milk provocation test at Yonsei university children's allergic clinic. RESULTS: 9 out of 21cases (43%) showed positive milk oral provocation test. The most common clinical symptom & sign was urticaria, followed by respiratory symptoms and abdominal symptoms. The rate which past history and positive skin test corresponded to oral provocation test was very high (100%). CONCLUSION: The most valuable diagnosis of food allergy is oral provocation test. However, predictive value of allergy skin test and past history was very high in milk allergy.

PURPOSE: Buckwheat is one of the most common food allegen in Korea and frequently elicit severe allergic reactions. However, up to now, only few reports on buckwheat allergens have been reproted. The purpose of this study was to isolate mRNA for the production of recombinant buckwheat allergens. METHODS: After the isolation of mRNA from ripening buckwheat seeds, in vitro translation was performed. The proteim patters of in vitro traslate products were identified using SDS-PAGE. RESULTS: A260/A260 ratio total RNA was 1.9 and mRNA was 2.0. In vitro translate products showed towered molecular buckwheat proteins such as 1, 3, and 14kD, while other high molecular weight protein of buckwheat seed were not shown in SDS-PAGE. CONCLUSION: mRNA of buckwheat was purified only from ripening seeds. The composition of mRNA was different according to the ripening periods. It is believed that this finding can give a clue to the basic research of buckwheat allergen.

BACKGROUND AND OBJECTIVE: Buckwheat is considered one of the most important food allergens in Korea. Although a very small amount is ingested or inhaled, it can cause serious allergic reactions. However, the major allergens of buckwheat still remain to be elucidated. The aim of our study was to identify and characterize the major allergen of buckwheat seed. MATERIAL AND METHOD: Dialysis membrane with a cut-off MW 1kD was used for the preparation of crude buckwheat seed allergen extract. SDS-PAGE under reducing conditions and IgE immunoblotting were performed using sera from 15 buckwheat sensitive subjects. Isoelectric focusing and lectin blotting assay were done. RESULT: Western blot analysis showed more than 15 IgE-reactive buckwheat proteins. Among them, a 24kD protein was shown to be the most frequently bound to sera from allergic subjects (54%). Isoelectric point of 24kD protein was around 5.9. In lectin blotting assay, 24kD protein did not bind to Con A nor five other lectins. CONCLUSION: A 24kD protein was the most frequently recognized allergenic component in buckwheat seed. Isoelectric point was around 5.9. Glycosylation was not detected in 24kD of buckwheat protein.

PURPOSE: Cat is the pet which many of us quite frequently contact without any specific precautions. According to the allergy skin tests conducted in children, cat antigen shows a comparatively high positive reaction, and past history also shows that there are many patients who suffer allergies from cat contacts. Therefore, once it is diagnosed as an allergy caused by cat, it is important that patients be isolated in order to restrict their contact with cat. In this context, this study was conducted for the purpose of finding out how serious and how frequent the allergies by cat contacts are. METHODS: Forty five children patients who visited to the Allergy Clinic for Children, Severance Hospital annexed to the Medical College, Yonsei University were enrolled in this study. Some of patients had shown a positive reaction against cat antigen in the allergy skin test, and others had a past history of developing symtoms when contacted by cat. The patients were isolated from cat for seven days, and then contacted with cats for 30 minutes and observed the provocated symptoms. RESULTS: 1) Among the tested patients, the number of cases who were provocated by the symptoms after cat contact were 18 (40%). 2) Among those patients who were shown to be positive only in allergy skin test, only 24.2% proved to be provocated by the symptoms, while 90.0% of those who had a past history in addition to allergy skin test proved to be provocated by the symptoms. 3) Symptoms provocated after cat contact showed allergic rhinitis patients 88.2% which was the highest ratio, bronchical asthma, 35.3%, urticaria, 29.4%, and allergic conjunctivitis, 23.5%, respectively. 4) The onset and duration of symptoms provcated were under 10 minutes and from 30 to 60 minutes, which included most cases in the test. 5) Total IgE and eosinophil count of patients did not show any meaningful differences between the group which was provocated and that which was not provocated. CONCLUSION: It was shown that 40% patients who were suspected of cat allergy had a positive reaction to the cat contact provocation test. Ninety percents of patients who showed both positive allergy skin test and past history were provocated after cat contact.
