BACKGROUND: Eotaxin, a CC chemokine specific for eosinophils, is implicated in the pathogenesis of asthma recruiting eosinophils into the airways. Theophylline has been used for the treatment of asthma and rece was proposed to have an anti-inflammatory action. The aim of this study is to examine whether theophylline may inhibit the eosinophilic airway inflammation by reducing the expression of eotaxin. METHODS: The expression of eotaxin mRNA was assessed by Northern analysis in A549 cells 4 h after stimulation with TNF-α or IL-1β And then, theophylline was added to A549 cells stimulated with 0.1 ng/ml IL-1β. RESULTS: Eotaxin mRNA expression rates induced by 0.1, 1, 10 ng/mL TNF-α as compared with β-action were 7%, 22%, 28%, respectively. Eotaxin mRNA expression rates induced by 0.01, 0.1, 1, 10 ng/ml IL-1β as compared with β-action, were 10%, 42%, 63%, 72%, respectively. Eotaxin mRNA expression rates after addition of 0, 0.001, 0.01, 0.1 µM dexamethasone induced by 10 ng/mL TNF-α, as compared with β-action were 27%, 18%, 8%, respectively. Eotaxin mRNA expression rates after the addition of 0.001, 0.01, 0.1 mM dexamethasone induced by 0.1 ng/mL IL-1β, as compared with β -action, were 43%, 47%, 12%, 8%, respectively. Eotaxin mRNA expression rates after the addition of 0, 0.001, 0.01, 0.1, 1, 10 mM theophylline induced by 0.1 ng/mL IL-1β, as compared with β-action, were 48%, 40%, 33%, 22%, 16%, 14%, respectively. CONCLUSION: These results suggest that theophylline may reduce eosinophil infiltration of the airway at least in part by reducing the expression of eotaxin under the conditions of these experiments.

CT was found to be highly accurate in predicting tumor size and assessing invasion of the surroundingstructures and distant metastasis. Also CT played an important role for determination of operability of esophagealcarcinoma. The CT findings with barium esophagogram in 21 patients with histologically proven esophageal carciomawere reviewed from Feb. 1985 to Feb. 1986 at the department of Radiology, Yonsei University ,College of Medicine.The results were as follows: 1. Number of patients in each stages were: 2 in stage 1, 6 in stage 2, 4 in stage 3,and 9 in stage 4. 2. Peak age distribution was in its 6th decasedes as 9 patiens (42.9%). Overall mean age was 60.8 years. Number of male patients were 19 and 2 of female. 3. Histologic types of esohageal carcinoma were 19cases of epidermoid (90.5%) and 2 cases of adenocarcinoma(9.5%). 4. The tumor location was 1 case in upper, 14cases(66.7%) in middle and 6 cases in lower one-third. 5. Various types of esophageal carcinoma were as follows: 3cases of fungating, 4 cases of infiltrating, 5 cases of ulcerofungating, and 9 cases of ulceroinfiltrating type.6. Average length of involvement in each stages were 4cm in stage 1, 5.5cm in stage 2, 8.8cm in stage 3, and 8.3cmin stage 4. The involved length was longer in advanced cases. In 11 cases(52.4%), the involved length was between4 and 8cm. 7. Angle of periaortic fat plane obliteration of the aortic circumference were as follows: Below 45degrees( 7 cases 33.3%), 45degrees-90degrees (3 cases 14.3%), over 90 degrees(11 cases, 52.4%). 8. Method oftreatment of esophageal carcinoma were as follows: Only radiotherapy in 11 cases(52.4%), radiotherapy withoperation in 5 cases, only operation in 1 cases, and no treatment in 4 cases. 9. Distant metastatic sites were:brain in 1, pericardium in 5, liver in 5, trachea in 2, bronchus in 9, and distant lymph node in 5 cases.

Epiblepharon is frequently encountered n oriental eyelid, especially in children. It is characterized by a horizontal fold of redundant skin and abundant orbicularis muscle near lid margin, which the lashes vertically, or posteriorly towards the eye. Surgical therapy of epiblepharon in correcting the trichiasis includes lid bracing sutures, burried sutures, skin resection, a Hotz procedure or its modification, and a Jones procedure. In our opinion, these procedures are not sufficient, because these procedures will not correct the epicanthal folds. Epicanthal folds have been a one of the characteristics of Asian over 50 percents of population in Japan and South Korea, and it either reduce the aesthetic result of the double-eyelid procedure or make the correction of the entropion and epiblepharon difficult. Although many surgical procedures are available to eliminate epicanthal folds, scarring on the medial canthus is in still and obstacle for surgeons to overcome. From January of 1998 to October of 1998, we used half z-plasty procedures in 5 cases to correct epicanthal folds in epiblepharon. There were few complications in our series. We believe that half z-plasty can get a good result in the correction of epibolepharon and oriental epicanthal folds.

BACKGROUND: It is well known that when macrophages are stimulated with endotoxin, they produce a wide variety of cytokine mediators, including TNF-α and IL-1β. However, there is an alterationnin the macrophages responsiveness when they are challenged with repeated bouts of endotoxin, termed 'endotoxin tolerance' which is regarded as a self-protective phenomenon from continuous stimulation. In this study, endotoxin tolerance in the peripheral blood monocytes of sepsis patients was evaluated. METHODS: Fourteen patients with organism-documented sepsis were included. The severity of illness was evaluated by APACHE IIscore. Peripheral blood monocytes were isolated from the patients and diluted to 1×105/well. After stimulation with endotoxin(LPS of E. coli O114:B4, 100 ng/ml), they were incubated at 37℃ in 5% CO2 incubator for 24 hours. Supernatant was collected for the measurement of TNF-αand IL-1β with ELISA method. Peripheral blood monocytes of seven healthy volunteers were used as control. RESULTS: The APACHE IIscore(mean±SD) of the patients at the time of blood sampling was 12.2±5.7. The primary infection foci were urinary tract infection, pneumonia, subacute bacterial endocarditis, and catheter related infection, etc. The causative organisms were gram negative rods(10 cases), gram positive cocci(6 cases) with two cases of mixed infection. Serum TNF-α could be measured in 4 cases with 29.9±27.7 pg/ml. Serum IL-1β was measureable in only one patient. The TNF-α level of supernatant of cultured peripheral blood monocytes was 2,703±2,066 pg/ml in patients and 2,102±1,914 pg/ml in controls. The IL-1β level of supernatant was 884±1,050 pg/ml in patients and 575±558 pg/ml in controls. There was no difference of TNF-α and IL-1β level between patients and controls. CONCLUSION: We cannot prove the phenomenon of endotoxin tolerance in this study. Future study needs to be focused on the more severe sepsis patients who were taken for sampling earlier. Addition of serum to the culture medium could be an another valuable option for the success of this study.

A 64-year-old male was admitted due to weight loss of 5kg during a month. Chest X-ray showed two large, lobulated masses on both lower lobe. Chest CT showed ill-defined, multilobulated mass on left lower lobe and r-regular, relatively homogenous mass with air-bronchogram on right lower lobe. Left lower lobectomy and right lower lobectomy was performed sequentially with three months intervaL Microscopic findings showed squamous cell carcinoma of both mass. It was thought that this patient had synchronous double primary lung cancer.

PURPOSE: Prader-Willi syndrome (PWS) is a complex genetic disorder, caused by the deletion of the paternally derived 15q11-13 region or the maternal uniparental disomy of chromosome 15 (mUPD(15)). In this study, we compared phenotypic differences between those patients whose disease was caused by microdeletion and those caused by mUPD(15). In addition, a comparison of the efficacy of growth hormone (GH) therapy between these two PWS genotypes was analyzed. METHODS: Fifty-three patients were diagnosed as having PWS based on molecular and cytogenetic analyses and clinical features. Data that included maternal age, birth weight, a feeding problem in the neonatal period, cryptorchidism, developmental delay or mental retardation, short stature, hypopigmentation, changes in height, weight, and body mass indexes (BMI) before and after GH treatment were obtained by a retrospective review of medical records. The data from the patients with microdeletion were compared with those from the patients with mUPD(15). RESULTS: Of the 53 patients with genetically confirmed PWS, 39 cases had microdeletion and 14 mUPD(15). Maternal ages were significantly higher in the mUPD(15) group, and hypopigmentation and a feeding problem in the neonatal period were more frequent in the microdeletion group. Growth hormone was administered to 20 patients [14 with microdeletion, 6 with mUPD(15)]. There were no differences between the two groups in height velocity, weight and height SDS, and BMI after GH therapy. CONCLUSION: Phenotype and genotype correlations were observed in Korean PWS patients, such as more advanced maternal ages in the mUPD(15) group and more feeding problems and hypopigmentations in the microdeletion group. Further long-term prospective studies are needed to correlate other aspects of the phenotypes.
