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.

Digital subtraction angiography(DSA) was made in 72 patients at department of radiology, Seoul National University hospital from February 1982 to January 1983 with our system, SRM-II, developed by cooperation of department of medical engineering, Seoul National University Hospital. The results were as follows; 1. In the total 72 cases, vascular disease was 28 cases in which aortic disease including Takayasu's aortitis was 18 cases. Others were vascular tumors in 32 cases and various conditions such as renal donor and artificial arteriovenous shunt. 2. Extent of the lesion was well delineated especially in aortic disease in cluding 8 cases of Takayasu's aortitis, 6 cases of aortic aneurysm and 2 cases of Behcet's syndrome. 3. DSA can be done to outpatient without admission because of its simplicity and non-invasiveness. DSA is useful especially in the evaluation and follow-up of vascular disease and the diagnostic value is expected to grow continuously according to the renewal of system.

Recently, technical developments in digital electronics and imge intensifier have improved the electronicrecording and processing of images. Both departments of radiology and of medical engineering of Seoul National Univeristy Hospital jointly developed idgital subtraction angiography system(SRM-I) and performed DSA in patients. The system was composed of angiography equipments, computer, video image storage and logarithmic amplifier. Fluoroscopic images were taken before and after 40-60 ml of contrast media were intravenously injected with speedfo 12-15 ml/sec. The images were recorded by V.T.R. with normal speed. The recorded images were processed with digitization, amplification, sutraction, enhancement, position manipulation and image smoothing. Arteriography of neck vessels, abdominal aorta and its branches and extremities were performed successfully by above mentioned methods in 20 cases and results were reviewed.

Hailey-Hailey disease(benign familial chronic pemphigus) is a rare autosomal dominant disorder characterized by blisters at sites of friction such as the neck, axillae and groin which are caused by suprabasal epidermal acantholysis. We report two cases of Hailey-Hailey disease in the one family. One of the two cases has asymptomatic multiple longitudinal white bands in the fingernails associated with typical skin lesions. The nail lesions have not been described until reported by Burge in 1992 and it may be a characteristic finding in Hailey-Hailey disease.

The monoclonal antibody Ki-1(CD30) was first described in 1982 and was reported to react selectively with Reed-Sternberg cells in Hodgkins disease, highly activated B and T cells and large cell lymphomas of both T-and B-cell origin. Lymphomatoid papulosis(LyP) is characterized by recurrent erythematous papules or nodules that undergo spontaneous healing with hyperpigmentation and scarring. Histologically, two major types of LyP can be distinguished: type A is characterized by the presence of variable numbers of Ki-1+ large, atypical lymphocytes with some Reed-Sternberg like cells and type B is characterized by Ki-1- atypical cerebriform mononuclear cells similar to those in mycosis fungoides. We report a case of Ki-1+ lymphomatoid papulosis which was histopathologically recognized as a type B lesion but represented a Ki-1 positive reaction.

Kaposis sarcoma is a multicentric neoplastic vascular tumor involving the skin or internal organs. We report a case of classic Kaposis sarcoma in a 69-year-old male who had positive serum cytomegalovirus antibodies and disseminated multiple erythematous to purplish colored confluent papules and edema on both lower legs. The histopathological finding showed abnormally proliferated and dilated vessels, vascular spaces, spindle cells, and extravasated erythrocytes. He was treated with radiotherapy, but died due to ventricular tachycardia.

We report two cases of recurrent extramarnmary Pagets disease after wide local excision. Both cases involved the scrotum and the penoserotal junction, respectively. On histopathological examination, we could observed many Paget cells confined to the epidermis and the hair follicle, but not invading the underlying dermis in both cases. There was no evidence of internal malignancy. Both cases were treated with wide local reexcision.

OBJECTIVE: Biomarkers of attention deficit hyperactivity disorder (ADHD) are crucial for early diagnosis and intervention, in which the identification of biomarkers in other areas of the body that represent the immature brain of children with ADHD is necessary. The present study aimed to find biomarkers of ADHD in the retina and assessed the relationship between macular thickness of the retina and cortical thickness of the brain in children with ADHD. METHODS: Twelve children with ADHD and 13 control children were recruited for the study. To find ocular markers of ADHD, we investigated the correlation between clinical symptoms of ADHD assessed with the Korean ADHD Rating Scale (K-ARS), cortical thickness of the brain, and macular thickness measured with the mean thickness from the Early Treatment Diabetic Retinopathy Study (ETDRS). RESULTS: Children with ADHD showed increased macular thicknesses quantified as an ETDRS ring in both eyes, compared to control subjects. Moreover, the right inner ETDRS ring had a positive correlation with K-ARS scores. The ADHD group had an increased ratio of thickness of the right frontal lobe to that of the parietal cortex, compared with the control group. There were positive correlations between the means of the inner ETDRS ring (right) and the left paracentral/right isthmus cingulate thicknesses in the control group. However, there were negative correlations between the means of the inner ETDRS ring (right) and the left frontal pole/right pars triangularis thicknesses in the ADHD group. The results of both groups were at the uncorrected level. CONCLUSION: The different patterns of macular thickness might represent the immature cortical thickness of the brain in children with ADHD.

'Num-chin syndrome', isolated mental neuropathy, is a rare manifestaion of malignant hernatologic diseases, but important sign for early diagnosis and prediction of clinical course and prognosis. Here we report 7 cases of numb-chin syndrome; one in leukemic transformation of malignant lymphoma, one in blastic crisis of chronic myelogenous leukemia and 5 in acute leukemia Two cases of acute leukemia revealed the 'numb-chin sign' in early course of disease before the diagnosis of leukemia and other three in aggravating state of acute leukemia. The therapeutic response and prognosis was poor and 5 cases expired in a few months.
