BACKGROUND: Since the demonstration of the fact that vascular relaxation by acetylcholine(Ach) results from the release of relaxing factor from the endothelium, the identity and physiology of this endothelium-derived relaxing factor(EDRF) has been the target for many researches. EDRF has been identified as nitric oxide(NO). With the recent evidences that EDRF is an important mediator of vascular tone, there have been increasing interests in defining the role of the EDRF as a potential mediator of hypoxic pulmonary vasoconstriction. But the role of EDRF in modulating the pulmonary circulation is not compeletely clarified. To investigate the endotbelium-dependent pulmonary vasodilation and the role of EDRF during hypoxic pulmonary vasoconstriction, we studied the effects of N(G)-monornethyl-L-arginine(L-NMMA) and L-arginine on the precontracted pulmonary arterial rings of the rat in normoxia and hypoxia. METHODS: The pulmonary arteries of male Sprague Dawley(300~350g) were dissected free of surrounding tissue, and cut into rings. Rings were mounted over fine rigid wires, in organ chambers filled with 20ml of Krebs solution bubbled with 95 percent oxygen and 5 percent carbon dioxide and maintained at 37℃. Changes in isometric tension were recorded with a force transducer(FT. 03 Grass, Quincy, USA). RESULTS: 1) Precontraction of rat pulmonry artery with intact endothelium by phenylephrine(PE, 10(-6)M) was relaxed completely by acetylcholine(Ach, 10(-9) -10(-5)M) and sodium nitroprusside (SN, 10(-9) -10(-5)M), but relaxing response by Ach in rat pulmonary artery with denuded endothelium was significantly decreased. 2) L-NMMA(10-4M) pretreatment inhibited Ach(10(-9) -10(-5)M)-induced relaxation, but L-NMMA(10-4M) had no effect on relaxation induced by SN(10(-9) -10(-5)M). 3) Pretreatment of the L-arginine(10(-4)M) significantly reversed the inhibition of the Ach(10(-9) -10(-5)M)-induced relaxation caused by L-NMMA(10(-4)M). 4) Pulmonary arterial contraction by PE(10(-6)M) was stronger in hypoxia than normoxia but relaxing response by Ach(10(-9) -10(-5)M) was decreased. 5) With pretreatment of L-arginine(10(-4)M), pulmonary arterial relaxation by Ach(10(-9) -10(-5)M) in hypoxia was reversed to the level of relaxation in normoxia. CONCLUSION: It is concluded that rat pulmonary arterial relaxation by Ach is dependent on the intact endothelium and is largely mediated by NO. Acute hypoxic pulmonary vasoconstriction is related to the suppression on NO formation in the vascular endothelium.

Kerion celsi is an inflammatory infection, caused by a vigorous T-cell mediated host response to the dermatophyte infection. In the case of severe inflammation, it can be misdiagnosed as other disease like cellulitis, impetigo, furuncle and epidermal cyst. Microsporum(M.) canis is most likely transmitted by contact of animal hosts such as cats and dogs with humans. We report the 75-year-old female who presented two months history of tender erythematous scaly plaques with pustules, crusts on right scalp area. At first, from the histopathologic findings of the lesion, the patient was diagnosed epidermal cyst because of cyst-like structure in mid-dermis. But the fungal culture revealed M. canis as the causative fungus. Herein we report a educational case of kerion celsi mistaken for ruptured epidermal cyst.

PURPOSE: The purpose of this study is to evaluate the outcome of treatment for patients with Type IIIb open tibial fractures. MATERIALS AND METHODS: This study targeted 35 adult patients for whom follow-up was possible over one year after undergoing surgical treatment. There were 29 males and six females with an average age of 45 years. RESULTS: Fracture location was proximal in 10 cases, midshaft in 13 cases, and the distal part of the tibia in 12 cases. An average of 10 days was observed for definitive fixation with soft tissue coverage of the injury. The mean time to radiographic union was 27 weeks. Sixteen cases (45.7%) of complications were observed. Three cases of superficial infection, two cases of deep infection, four cases of partial flap necrosis, three cases of mal-alignment, three cases of joint stiffness, and one case of hardware breakage were observed. The mean lower extremity functional scale score was 68.5 and the factors influencing the clinical results were severity of open wound (p=0.000) and occurrence of complications (p=0.000) according to results of multiple regression analysis. CONCLUSION: In treatment of Type IIIb open tibial fractures, good clinical results can be expected provided that complications are prevented through proper reduction, firm fixation, early soft tissue reconstruction, and early rehabilitation.

A hemangioma is a common soft tissue tumor, usually affecting the cutaneous regions of the head and neck in infancy and childhood. A hemangioma in the gastrointestinal tract is rare occurrence which is usually found in the submucosa of the small and large intestine, but rarely in the stomach. Infrequently, multiple cavernous hemangiomas have been reported on skin and in the intestines. A 23-year-old man was admitted with hematemesis. An upper endoscopy revealed a purple colored sessile lesion at the posterior wall side of the fundus which had surface erosion and erythema. This lesion was easy to bleed when the patient retched. Another sessile lesion was detected at the greater curvature side of the upper body. The patient had two intradermal soft masses at the back and left forearm. An X-ray revealed a phebolith that suggested a cavernous hemangioma. An abdomen CT and angiography revealed that these lesions were highly suggestive of hemangioma. Gastric wedge resection was performed and the histological diagnosis was gastric cavernous hemangiomas.

OBJECTIVE: The purpose of the study was to develop the Korean version of the Stage of Change Readiness and Treatment Eagerness Scale for Smoking Cessation (K-SOCRATES-S) based on the Korean version of the Stages of Readiness for Change and Eagerness for Treatment scale (K-SOCRATES). This paper also demonstrates its reliability and validity among patients with nicotine dependence in South Korea. METHODS: At seven healthcare promotion centers in Gyeonggi-do, 333 male smokers aged 20 to 70 who visited smoking cessation clinic were recruited for this study and the K-SOCRATES-S was administered. After three months, the number of respondents who successfully stopped smoking was assessed by testing their urine cotinine level. Subsequently, exploratory factor analysis was performed to verify the reliability and validity of the K-SOCRATES-S. Also, a logistic regression analysis was performed to examine the variables that can predict the successful cessation of smoking on subscales of the K-SOCRATES-S. RESULTS: Exploratory factor analysis of the K-SOCRATES-S showed that the scale consisted of three factors: Taking Steps, Recognition, and Ambivalence. The scales measuring Taking Steps and Recognition in this scale had a significantly positive correlation with the scores observed on Kim's smoking cessation motivation scale. The scales measuring Taking Steps and Recognition had a significantly negative correlation with Ambivalence. Overall, the results indicate that the K-SOCRATES-K scale showed high validity. CONCLUSION: The K-SOCRATES-S developed in the present study is highly reliable and valid for predicting a patient's likelihood of success in quitting smoking among patients who want to cease smoking.

While angina pectoris is not uncommonly seen in hyperthyroidism, only rare case reports have proved that the myocardial ischemia was induced by coronary artery spasm. A 62 year-old man with a prior diagnosis of hyperthyroidism presented with repeated episodes of syncope and chest pain. The coronary angiogram showed normal coronary arteries. Severe diffuse spasm of both coronary was spontaneously induced and normalized after intracoronary nitroglycerin injection during the procedure of coronary angiography. For one year, he was on simultaneous antianginal and antithyroidal medicines with accomplishment of euthyroid state. He did not experience and anginal symptom for the last six months. The followup coronary angiogram performed 1 year later revealed a newly developed atherosclerotic lesion (about 50% stenosis in diameter) at the proximal left anterior descending artery. However provocative challenge test with intracoronary acetylcholine infusion failed to induce coronary spasm at the lesion. We report a case of coronary artery spasm associated with hyperthyroidism with a review of literatures.
