국내 중증 만성정신질환자 수를 추정하기 위하여 일 농촌 및 대도시 지역의 지역의료보험 및 의료보호 대상자 중 1993년 1년간 의료기관에서 정신증 상병(ICD-9 code 상 290-299) 및 알콜 남용/중독, 성격장애 및 정신박약 진단하에 치료를 받은 적이 있는 사람에 대해 설문조사를 실시하였다. 연구자들이 개발한 진단도구를 이용하여 진단을 평가하고, Strauss-Carpenter scale 등을 이용하여 기능 장애를 평가하고 유병기간 등을 조사하였다. 결과를 요약하면 다음과 같다. 1) 진단평가상 정신분열병군(61.1%)이 가장 많았으며, 정동장애군(23.7%), 알콜장애군(11.2%), 기질성 정신장애군(4.0%)의 순서이었다. 2) 직업활동정도는 진단군별로 차이가 많았다. 지난 1년간 직업활동이 6개월 미만이거나 전혀 없는 환자 비율이 정신분열병군은 67.2%, 알콜장애군 52.0%, 정동장애20.8%의 순으로 정신분열병군이 가장 불량하였다. 3) 사회활동도 진단군별로 차이가 많아서 지난 1년간 의도적, 사회활동이 없는 비율이 정신분열병군이 가장 높았고(72.3%), 알콜장애군(32.0%), 정동장애군(20.7%)의 순이었다. 4) 국내 의료보험 및 사회복지시설 이용 자료 등을 토대로 본 조사 결과를 적용한 결과 국내중증 만성 정신질환자의 수는 약 8만 7천명으로 추산되었다. Objectives: The purpose of this study was to estimate the number of serious and persistent mentally ill patients in Korea. Methods : Study populations were recruited from medical insurance data of two district areas ; one rural and the other urban areas. Subject were all mentally ill who had ever visited any hospital in 1993 and were diagnosed as having psychosis, personality disorder and drug abuse. We conducted a home visiting survey applying semi-structured diagnostic interview, assessing the level of social adjustment with Strauss-Carpenter Scale, and past psychiatric history by the trained researchers, in October and November,1994. Results : According to diagnostic assessment schizophrenic patients constituted the major portion(61.1%) of study subjects. The distribution of occupational functions and social contacts was variable according to diagnosis. Most schizophrenic patients were unemployed or worked less than 6 months in the previous year(67.2%), and showed poor social contact(72.3%). But affective disorder patients were relatively independent in job maintenance and social relationship. Alcoholic patients lay between those of schizophrenic and affective disorder groups. It was estimated that about 87,000 adult Koreans were suffering from chronic mental disorders which seriously interfere with their daily life. Conclusions : Serious and persistent mentally ill patients were common in Korea. Community support program should be provided for them.

The purpose of this study was to investigate the distribution of CGRP immunoreactive nerve fibers in rat squamosomandibular joint with postnatal development. Squamosomandibular joint with adjacent tissue of 8 groups of rats(1,5,10,15,20,25,35-postnatal day and adult groups) were removed en bloc and processed for immunohistochemistry and were subjected to light microscopic examination. The results obtained were as follows; 1. The anterior portion of the articular disk was most densely innervated, followed by the posterior, lateral, and medial portions in each group. 2. Increase of CGRP immunoreactive nerve fibers was evident in 10,15,20 postnatal day groups. 3. Almost no CGRP immunoreactive nerve fibers were observed in articular surface of disk proper, mandibular fossa and condyle head of each group. These result suggest that CGRP immunoreactive nerve fibers increased in synovial membrane and peripheral portion of articular disk during 10-20 postnatal day may play a important role in squamosomandibular joint function after weaning period.

Background and Objectives : Epistaxis is a common disease from which approximately 10% of the normal population have suffered in their life. Most bleeding sites of epistaxis are located anteriorly and easily controlled. However posterior epistaxis presents significantly great problems. A number of different treatment modalities are used to control the posterior epistaxis. Although not widely practiced, the nasal endoscopic electrocautery has also been effective. The purpose of this article is to report on the efficacy of nasal endoscopic electrocautery as an alternative and adjuvant to the standard approach for control of posterior epistaxis. Materials and Methods: We conducted retrospective chart review about 19 cases of posterior epistaxis treated from January 1998 to December 1999. Group I patients were managed by nasal packing only and group II patients were managed by nasal packing and endoscopic electrocautery. Results: Hospital days were 5.9 days in the group I and 3.6 days in the group II. The duration of nasal packing was 4.1 days in the group I and 1.8 days in the group II. The results were significant statistically Conclusion: Nasal endoscopic electrocautery was an effective treatment modality for control of posterior epistaxis.

Purpose: The vascular clipping system (VCS) is beneficial as it is simple and easy to apply formicrovascular suturing. Arteriovenous fistula (AVF) creation is a very basic standard technique ofmicrovascular surgery. In this study the VCS and the conventional suture methods were compared ina rabbit model using the carotid artery and vein to create an AVF. Methods: There were 28 rabbits assigned equally into 2 groups using the AVF creation method(conventional suturing or the VCS procedure). Histopathology was performed on fixed samples. Theprocedure time of the 2 methods and changes in histopathology of tissue samples after surgery werecompared. Results: The VCS procedure showed a lower degree of fibrosis and hyperplasia histologicallycompared with the conventional suture method. The VCS was quicker to perform and no significantanastomosis stricture was observed. Conclusion: In a rabbit model of AVF, the VCS has benefits over the conventional suture method. The VCS provides comparable patency rates, produces fewer side effects such as fibrosis andhyperplasia, and takes less operation time than suturing. The VCS is expected to be useful for caseswhere renal patients need periodic hemodialysis and thus repetitive access to a vessel.

Hepatopulmonary Syndrome Induced by Common Bile Duct Ligation in a Rabbit Model: Correlation between Pulmonary Vascular Dilatation on Thin-Section CT and Angiography and Serum Nitrite Concentration

Hepatopulmonary syndrome consists of a triad of hepatic dysfunction and/or portal hypertension, peripheral pulmonary vascular dilatation, and hypoxemia in the absence of detectable primary cardiopulmonary disease (1-3). Although the disease pathogenesis is not precisely known, reports show that a vasoactive substance imbalance is likely to be responsible (4-9), and the leading contender seems to be nitric oxide (4-12). Increased circulating nitric oxide or nitric oxide synthase may account for the vasodilatation observed in hepatopulmonary syndrome. Moreover, the development of an animal model of hepatopulmonary syndrome, i.e., common bile duct ligation has provided us with a means of investigating the mechanism of intrapulmonary vascular dilatation (4-7, 9-14). However, most investigations have been focused on intrapulmonary vascular dilatation with respect to the microvasculature at the capillary and precapillary levels (4-6, 10-12, 14),though some authors (7, 14, 15) have documented radiologic findings of hepatopulmonary syndrome at the point of the peripheral pulmonary vasculature. However, to our knowledge no study has been undertaken in which pulmonary peripheral vessels were visualized on thinsection CT and pulmonary angiography and correlated with serum nitrite concentration and immunostainings. The aim of this study was to investigate the correlations between the radiologic finding of vascular dilatation with serum nitrite concentration and endothelial nitric oxide synthase (eNOS) expression in a rabbit model of hepatopulmonary syndrome induced by common bile duct ligation(CBDL).

( Ji Oung Kang ),( Hee Jin Kwon ),( Jin Han Cho ),( Jong Young Oh ),( Kyung Jin Nam ),( Seong Kuk Yoon ),( Myong Jin Kang ),( Sung Wook Lee ),( Sang Yeong Han ) 대한소화기학회 2012 Gut and Liver Vol.6 No.3

Background/Aims: The purpose of this study was to as-sess the value of acoustic radiation force impulse (ARFI) for predicting the extent of radiofrequency ablation (RFA) in hepatocellular carcinoma (HCC) by correlating the elastic-ity of HCC and peritumoral parenchyma (as measured by ARFI) with the extent of ablation determined by computed tomography (CT). Methods: From September 2009 to June 2011, 158 patients underwent RFA ablation for HCC (single, ≤3 cm). We evaluated the data of a total of 38 prospectively enrolled patients who underwent both ARFI imaging and contrast-enhanced CT after one session of 12 minutes of RFA without a change in needle position. The ARFI imaging indices, including the mean shear wave velocity (SWV) of HCC, mean SWV of the peritumoral parenchyma and tumor size, were evaluated to determine the statistical correlation with RFA extent after one session of 12 minutes of RFA. Results: A stiffer liver parenchyma in patients with cirrhosis results in a smaller ablation zone. Conclusions: SWV of ARFI in liver parenchyma was well correlated with RFA extent. After evaluating the correlation between ARFI and RFA extent, we suggest that the SWV in liver parenchyma might be a non-invasive supplementary tool for predicting the extent of RFA.
