1.The Comparison of Endoscopic Variceal Band Ligation (EVL) with and without Over Tube.
Korean Journal of Gastrointestinal Endoscopy 1994;14(4):391-396
Endoscopic variceal band ligation requires the incertion of over tube. Since adopting EVL, we encountered pharyngeal trauma and complaints of severe pain during over tube insertion. So We compared the safety and efficacy of EVL according to the method of scope insertion, as over tube and free hand method. We studied 49 patients who require EVL due to grade 3 esophageal varices. The group l consist of 26 patients who undergone EVL without over tube and group 2 consist of 23 patients who undergone EVL with over tube. There were no differences in basal arterial oxygen saturation by pulse oxymeter, basal heart rate and EKG by EKG monitor, hemoglobin concentration, and Child class between 2 groups. The changes of arterial oxygen saturation and EKG were not different between 2 groups during EVL. And the symptom score and speed of single band ligation were similar in over tube and free hand method of EVL. The complication induced by scope insertion methods is minor pharyngeal trauma only in over tube group. We suggest that over tube method of EVL can be replaced by free hand method in patients who complain of severe pain during over tube insertion, and with anatomical abnormality of oropharynx and urgent cases in which require good vision.

2.Fixation of Properdin and Factor B by Bullous Pemphigoid Antibody (in vitro Study).
Korean Journal of Dermatology 1980;18(1):81-86
Ten serum samples from the patient with bullous pemphigoid with the baseruent mernbrane zone autoantibody titers of 320 or greater were tested, by the method of in vitro complement immunofluorescence, for their ability to fix Factor B and properdin in addition to Clq, C4 and C3. Five samples yielded positive C3 and properdin staining reaciions while four samples demonstrated positive Factor B stainings. All ten samples yieled positive C3, C4 and Clq staining reactions, Heat inactivation or treatment of the complement source with EDTA, MG2-EGTA abolished both C3, properdin and Factor B staining in all ten cases. This result suggest that pemphigoid antibody will fix properdin and Factor B in addition to Clq, C4 and C3, a phenomenon explained by assembly of the C3b amplification mechanism following activation of the classical pathway of complement system.

3.Plasmin and Its Inhibitors in the Lesional Skin of Pemphigus.
Korean Journal of Dermatology 1988;26(3):292-297
The exact pathomechanism of anti-epidermal cell pemphigus antibodies in developing acantholytic changes is unknown. Recent investigations have suggested that pemphigus antibodies, after binding to the antigenic site, induce activation of epidermal plasminogen activator. This increased activity of the plasminogen activator converts plasminogen to plasmin in high level degrades intercellular bridges resulting in loss of adhesion between epidermal cells. Author examined, by modified direct immunofluorescence, the deposition of plasmin and its inhibitor proteins such as alpha 1-antitrypsin and alpha 2-macroglobulin, with the early lesional skin specimens from 5 patients of pemphigus All these lesional skin demonstrated intense deposits of plasmin and aIpha 2-mscrogIobulin, and to a less degree alpha l-antitrypsin, all having indentical patterns to that of IgGautoantibodies. These proteins were also stained at the dermoepidermal junction and upper dermis, but less intensely. The identification of these particular proteins ; plasmin, alpha 1 antitrypsin, and alpha 2 macroglobulin, could be an alternate mean for the enzyme-histologic diagncsis of pemphigus.

5.Hypersensitivity pneumonitis induced by oyster mushroom spores.
Journal of Asthma, Allergy and Clinical Immunology 1998;18(1):84-89
Hypersensitivity pneumonitis due to the inhalation of oyster mushroom(pleurotos ostreatus) was demonstrated in a 44-year-old man who had cultiviated for 4 years. He had suffered from dyspnea, cough, myalgia and fever in the evening after working at first. After them he has experienced dyspnea aggravated. He showed not only positive reaction to the intradermal test but also to the bronchial challenge test such as 6 hr after inhalation falling down of FVC, FEV p, and DLCO in pulmonary function test and leukocytosis with fever upto 38.2C with antigenic extract of oyster mushroom spore. The size of spore was approximately 3.5 when measured by transmission electron microscopy.

8.Increased CD5 + B Cells in Neonatal Infections.
Korean Journal of Immunology 1997;19(3):399-406
PURPOSE: CD5+ B (B1) cell is a subpopulation of B cells and CD5+ B cells constitute a large fraction of B cells in neonates. CD5 B cells are closely related with autoimmune diseases but the roles and functions in neonates are still unknown. The quantitative changes of CD5+ B cells in neonatal infections were examined to investigate the involvement of CDS+ B cells in neonatal immune reaction to general immunologic stimuli such as infections. Methods: Ten normal neonates and eight neonates with acute febrile diseases were studied. Venous blood was drawn and mononuclear cells were separated by Ficoll-Hypaque. Half was double-stained with FITC-conjugated anti-CD5 and PE-conjugated anti-CD19, and another half with FITC-conjugated anti-CD4 and PE-conjugated anti-CD8. Stained samples were analyzed using fluorescent-activated cell sortor. ...continue...

9.The Effects of Local Radiation using Ho-166 Balloon on Porcine Coronary Restenosis.
Korean Circulation Journal 2000;30(9):1139-1148
BACKGROUND: Restenosis remains one of major clinical problems in the coronary intervention. The effects of local radiation using radioactive balloon loaded with Ho-166 on coronary restenosis in the porcine model were observed. METHODS: Overdilation injury was performed in porcine coronary arteries using control balloon [Group I, n=, left anterior descending artery (LAD)=, left circumflex artery (LCX)=, right coronary artery (RCA)=] and Ho-166 loaded polyurethane-coating balloon [Group II; n=0, 21.98.1 mCi (20 Gy at 0.5 mm in depth), LAD=, LCX=, RCA=] at 5 atm for 3 min. Follow-up quantitative coronary angiogram (QCA) and histopathologic findings were compared at 4 weeks after balloon injury between two groups. RESULTS: Acute or late thrombotic arterial occlusion was not observed in both groups. Diameter stenosis measured by QCA was not different between two groups (Group I: 11.61.6%, II: 7.68.4%, P=.44). On histopathologic study, injury score, external and internal elastic lamina area, and media area were not different between two groups. Neointimal area and histopathologic area stenosis were significantly higher in Group I (0.320.86mm2, 20.677.01%) than those of Group II (0.150.26mm2, 12.032.44%). By immunocytochemistry, proliferating cell nuclear antigen indices in neointima and media were 8.244.44%, 7.972.46% in Group I, and 7.172.25%, 5.471.44% in Group II, which were not different between two groups(P=.587, 0.089). CONCLUSION: Local radiation using Ho-166 balloon is effective in reducing neointimal proliferation in a porcine model.

10.Diagnostic Usefulness of Immunoblot Assay in Autoimmune Bullous Dermatoses.
Korean Journal of Immunology 1997;19(1):129-134
Immunologic or immunopathologic assays are neccesary for the diagnosis of autoimmune bullous dermatoses including pemphigus vulgaris (PV), bullous pemphigoid (BP), and epidermolysis bullosa acquisita (EBA). The objectives of this study is to compare the sensitivity and usefulness of indirect immunofluorescence 0F) with that of immunoblot assay using amplified alkaline phosphatase staining system in the diagnosis of the above diseases; detection of disease-specific IgG autoantibodies. We selected 4 patients in each bullous dermatosis of PV, BP, and EBA, who had serum levels of IgG autoantibodies at a titer of 1:80 or higher. In each three disease, 2 patients with negative serum antibodies or serum titer lower than 1:20, were also enrolled. Among the former 4-patient groups the titers of IgG antibodies found on indirect IF were in the range of 1:80 to 1:160, whereas the titers recognized by immunoblot assay were 1 or 2 dilutions higher in most of these patients. In the latter 2-patient groups, 4 out of the 6 cases revealed antibody-positive on immunoblot-staining membrane. The indirect IF can be performed easily and seems favorable in the aspect of cost-effectiveness. However, immunoblot assay with sensitive staining method would be warranted in cases of antibody-negative or atypical clinical variants of autoimmunebullous dermatoses to confirm the diagnosis.
