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.

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...

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.

During the summer season(July-August) in 1967, the insecticide tests for resistance on adult A. sinensis and C. tritaeniorhynchus were carried out in Gobu-Myun Jeongup-Gun, Chollapuk-Do, where many Japanese encephalitis cases occur every year. The mortality by 4.0% DDT in A. sinensis was 88.9% and by 4.0% dieldrin was 84.4%. Therefore the LC-50 of DDT for A. sinensis was 1.75%, while LC-50 of dieldrin was 1.1%. The mortality by 4.0% DDT in C. tritaeniorhynchus was 36.7%, and by 4.0% dieldrin was 6.0% The result indicates that A. sinensis in Korea is susceptible to DDT and resistant to dieldrin. C. tritaeniorhynchus is highly resistant to both DDT and dieldrin.

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.

1. Using the kidney of the rabbit weighing approximately 1.5kg the LDH isozymes, LDH-l through 5, were analyzed on the acetate strip by electrophoresis and it was found that the LDH-3 was the least active isozyme followed by the LDH-2, -4, -1, and -5 in increasing order of activity both in that cortex and the medulla, showing a specific distribution pattern in the two tissues. 2. The difference in the isozymic distribution pattern between the cortex and the medulla was confirmed by separating the H-and M-LDH by DEAE-cellulose, the ratio of M-/H-LDH being l. 441t the medulla and 3. O3 in the cortex, showing more active anaerobic metabolism in the latter than in the former. 3. The total activity of LDH in the 20% homogenate of the total kidney tissue was 10. 55 units/ml the cortical 2.98 units/ml. and the medullary 7. 37 unite/ml. 4. In the unilaterally nephrectomized rabbit. the cortex of the remaining kidney showed increased activities of both H- and M-LDH, but the medullary H-LDH decreased, resulting in increases of the ratio M-,H-LDH both in the cortex and in the medulla 5. In the unilaterally pedicle-clamped rabbit, LDH of the clamped kidney medulla decreased while that of the cortex increased, and LDH of the unclamped kidney showed elevated activity both in the cortex and in the medulla, yielding an increase in the ratio of M-/H-LDH. 6. The specific difference in distribution pattern of LDH igozymes between the cortex and the medulla of the rabbit kidney and an increase of the ratio of M-/H.LDH resulting from functional compensation following unilateral nephrectomy or pedicle clamping have been briefly discussed.
