We experienced a case of Reiter's syndrome. A 20-year-old Korean male patient of Reiter's syndrome was reported. He had been suffered from mucopurulent urethral discharge, followed by white scaly patches on the skin, fever, transient conjunctivitis and arthralgia. Initially he was treated with sodium salicylic acid (Aspirin), indomethacin 150 mg/day for arthralgia and prednisolone 30mg/day. In accordance with improvement of symptom., prednisolone was tapered to 12. 5mg, when methotrexate 20mg/wk was added for the prevention of side effects of long term use of corticosteroids, Conjunctivitis, arthritis, and skin lesions cleared within 7 months. With improvement of symptoms, prednisolone was tapered and methotrexate also was tapered slowly. Physical therapy for joint stiffness was done.

A case of epidermodysplasia verruciformis associated with squamous cell carcinoma occurred in 21 years old male. He had extensive flat-topped papules on the face, neck and the upper trunk, and verrucous lesions on the extremities, especially on the dorsa of hands and feet for 15 years. Several peanut sized ulcerative lesions on the forehead were noticed for 1 year and identified as squarnous cell carcinomi. The akin test with dinitrochlorobenzene, tuberculin, phytohemagglutinin, candidin and dermatophytin showed alI negative. T and B-cell counts were within norrnal limits, but IgG and IgD levels in serurn were incresed.

Nevus sebaceus is an ozganoid nevus of sebaceous differentiation first described by Jydassohn in 1895 and commonly develops on scalp or face as a single lesion. But it may be multiple end extensive, and often associated with abnormallities-convulsion, megtal retardation, neurological defects, skeletal defects, or ocular abnormalities. We have experienced a case of 22-year-old male who has since birth had- multiple nevus sebaceus on she left side of face and trunk, epidermal nevi on parts of the face, and wide nevus spilus and numerous pigmenteri nevi on the left side of trunk and the left upper extremity. He has histories of convulsions and mental retardation. EEG showed minimal abnormality. Skull x-ray and other routine examinations were within normsl limits. We report a case of nevus sebaceus syndrome which may be considered as a neurocutaneous syndrome.

Drowning is a leading cause of accidental deaths worldwide, but its pathological diagnosis remains a challenge for forensic pathologists owing to a lack of pathognomonic findings in drowning deaths and inconclusive autopsy findings caused by postmortem changes. The aim of the present study was to investigate the pathway taken by inhaled drowning medium through the airway after death in a variety of experimental conditions, including underwater pressurization. We used methylene blue dye to monitor the spread of drowning medium to the lungs. Results of theses experiments demonstrated that it is possible for a significant amount of downing medium to enter the airway during immersion after death. Our results suggest that autopsies of immersed bodies and interpretation of these findings should be performed with special care.

Isolated rat thoracic aorta which is pharmacologically precontracted by phenylephrine induces photorelaxation when exposed to long wave length UV-light. The aim of the present study was to characterize the mechanism of UV-light induced by photorelaxation in the rat aorta. 1. UV light relaxed both endothelium-intact and -denuded rat aortic rings contracted by phenylephrine. The magnitude of relaxation on UV light was dependent on the exposure time and slightly greatly in endothelium-denuded rings than in endothelium-intact preparations. 2. L-NAME (10 nM-100 uM) but not D-NAME completely inhibited the photorelaxation in a concentration dependent manner. 3. The UV-induced relaxation was inhibited by methylene blue (1 -100 uM), and verapamil (100 nM), and removal of extracellular Ca2+. In contrast, UV-light induced photorelaxation was potentiated by N(w)-nitro-Larginine (L-NOARG) treatment. 4. In immunocytochemical analysis of UV-light induced iNOS and eNOS expression in rat aortas, at which expression levels were increased in a time-dependent manner on UV-irradiation in aortic endothelium and smooth muscle, respectively. These results suggest that UV light-induced photorelaxation may be due to nitric oxide from exogenously administered L-arginine as well as endogenous nitric oxide donors such as amino acid and arginine derivatives. Additional suggestion is that UV light stimulates the expression of nitric oxide synthases, and its activity for nitric oxide generation is dependent on cytosolic Ca2+ originated from extracellular space.

BACKGROUND AND OBJECTIVE: House dust mites have been known as the most important allergens in respiratory allergic disease. Since environmental factors may have influences on the pathogenesis of allergic disease, the study using Korean house dust mites for immune and biologic reactions in house dust mite-sensitive allergic disease is considered as significant. MATERIAL AND METHOD: We made two in-house allergenic extracts of Korean house dust mites (D. farinae and D. pteronpsssinus) and performed this study for the allergen standardization by in vivo methods and for the evaluation of the reliabilities for clinical applications. RESULT: As a results of biologic standardization using skin prick test teachnique, the activity of 1: 1,500w/v of D. farinae extract was estimated 1,000 biology unit(BU), concentration that elicits a wheal of the same size as that of histamine dihydrochloride 1mg/ml. The activity of 1: 1,000w/v of D. pteronyssinus was condiered as 1,000BU. The activity of 1:100w/v of both D. farinae and D. pteronpssiuns extracts were considered as 100,000 Allergy Unit(AU), based on intradermal skin testing of 30 subjects with strong sensitive reaction. The concordant rates between results of skin prick test done with 5,000BU/ml concentration of in-house allergenic extracts and thoae with the commercially available allergen(Bencard Co., UK) were 84.6% and 81.0% for D. farinae and D. pteronpssinus, respectively. The wheal erythema size and A/H ratios induced by in-house extracts were significantly correlated with those induced by Bencard allergen. CONCLUSION: This results suggest that in-house extracts of the whole bodies of two house dust mites have good allergenic activities in vivo. It is considered to be clinically useful and reliable allergenic extracts.

In this study, clinical effectiveness of Pharmacia CAP system for determination of allergen specific IgE was evaluated depending on the results of Bencard skin prick tests in 100 atopic and 18 nonatopic asthmatics. The Pharmacia CAP specific IgE positive rates were higher as the SPT grades were increased : negative (n=623) (17.8%); + (n=81) (34.6%); 2+ (n=223) (56.5%); 3+ (n=106) (70.8%); and 4+/-< (n=127)3+ (92.1%), respectively. The overall concordant rate between Bencard SPT and Pharmacia CAP system was 81.7% with range of 70.7~92.1%. The Overall sensitivity of Pharmacia CAP system was 80.7%. The sensitivities for 10 allergens, which ranged from 57.5% to 100 %, were as followed; D.pteronyssinus (96.1%), D.farinae (96.7%), cat dander (61.5%), cockroach (65.2%), Aspergillus fumigatus (57.1%), ragweed (62.5%), mugwort (75.0%), Meadow fescue (100%), birch (62.4%), and oak (80.0%), respectively. Overall specificity of Pharmacia CAP system was 82.2%. The specificity of CAP system in nonatopic subjects (n=18, 160 test) was 94.4% which was quite different with the 77.6% of atopic subjects (n=100, 463 test). SPT A/H ratios were significantly correlated with Pharmacia CAP specific IgE concentration (KU/L) in D.pteronyssinus (r=0.520, p<0.001), D.farinae (r=0.490, p<0.001), A.fumigatus (r=0.315, p<0.01), mugwort (r=0.210, p<0.05), ragweed (r=0.213, p<0.05), birch (r=0.232, p<0.05), M.fescue (r=0.410, p<0.001). But, in cockroach (r=0.192, p<0.1), cat dander and oak pollen, SPT A/H ratios were not correlated with the concentration of specific IgE. These results suggest that Pharmacia CAP system is useful for etiologic evaluation of immediate hypersensitivity and quantitative evaluation of specific IgE in atopic asthma.

BACKGROUND AND OBJECTIVES: Ischemic preconditioning (IP) has been shown to reduce the infarct size and severity of arrhythmia in a post-ischemic reperfused heart. Angina before myocardial infarction reflects brief episodes of myocardial ischemia and may be a marker of ischemic preconditioning. We studied the effect of a history of previous angina on early outcomes (infarct size, left ventricular (LV) function and residual myocardial ischemia) for patients with acute myocardial infarction (AMI) after thrombolytic therapy. MATERIALS AND METHOD: We examined prospectively 58 consecutive patients who had AMI and arrived hospital within 6 hours after chest pain developed. IP was defined as prodromal angina within 24 hours before myocardial infarction. Patients were divided 2 groups:Group I (Gr I, 30 cases) without IP, Group II (Gr II, 28 cases) with IP. Thrombolytic therapy was done 23 cases (77%) and 21 cases (75%) respectively in each groups. Thereafter, electrocardiographic findings, infarct size on the basis of peak creatine kinase, LV function on the 2-D echocardiographic findings, recurrent myocardial ischemia were examined between 2 groups. RESULTS: In predischarge 2-D echocardio-graphic findings, LV dilatation and normal regional wall motion did not differ between two groups. But, there were significantly smaller creatine kinase (CK)-determined infarct size in Gr II than that in Gr I (peak CK level, Gr I:1566.3+/-960.0 IU/L vs Gr II:1066.9+/-773.2; p<0.05). The time interval between the onset of infarction and peak CK level was shorter in Gr II than that in Gr I (Gr I:18.3+/-8.3 vs Gr II:10.7+/-3.4 hours; p<0.001). There were significantly more common incidences of residual myocardial ischemia in Gr II (Gr I:26.7% vs Gr II:60.7%; p<0.01). CONCLUSION: Patients with a history of prodromal angina preceding myocardial infarction had small infarct size and earlier reperfusion of infarct related artery. However, there were significantly more common residual myocardial ischemia in these patients and a trend toward re-infarction on same previous infarction sites.
