목적: 성인 남성과 폐경기 여성에서 철결핍 빈혈의 가장 흔한 원인은 위장관 출혈이며, 출혈 관련 위장관 병변을 발견하기 위해 상, 하부 위장관내시경을 사용한다. 이번 연구는 철결핍빈혈이 있는 환자에서 위장관 내시경 검사를 통해 진단된 위장관 질환의 임상적 특징과 출혈 연관 병변에 대한 예측인자를 알아보고자 하였다. 대상 및 방법: 2001년부터 2004년까지 철결핍빈혈로 진단 받은 189명의 의무기록을 후향적으로 조사하였다. 이들 가운데 상, 하부 위장관 내시경을 시행한 78명의 환자들을 대상으로 하였다. 현성 출혈이 있거나 소화기계 이외의 다른 원인에 의한 빈혈을 가진 경우는 제외하였다. 결과: 총 78명 환자의 평균연령은 49.3세였고 남녀 비는 1:2.7이었으며, 27.7%에서 출혈 연관 병변을 가지고 있었다. 상부위장관 내시경검사에서 확인된 출혈 연관 병변은 소화성 궤양(13.6%), 미란 위십이지장염(12.6%), 위암(5.1%)의 순이었고, 하부위장관내시경검사에서는 대장 용종(11.5%), 염증성 장질환(6.4%), 대장암(3.8%)의 순이었다. 출혈 연관 병변이 있는 환자들의 경우 평균 연령은 54.8세로 병변이 없는 환자들의 평균 연령 43.7세에 비해 의미 있게 높았고(p=0.026), 출혈연관 병변이 있는 환자들의 세망세포비(reticulocyte count)는 2.8%로 없는 환자군의 2.0%에 비해 의미 있게 높았다(p=0.002). 하지만 혈색소, 평균적혈구용적(mean corpuscular volume, MCV), 혈청 철, 페리틴(ferritin), 총철결합능(total iron binding capacity, TIBC)과 상, 하부 위장관 증상의 동반 여부 등은 두 군 간에 차이가 없었다. 결론: 이번 연구에서 상, 하부 위장관 내시경을 통해 발견된 철결핍빈혈 관련 위장관 병변들 중 상부위장관 질환의 유병률이 높았으며 위암이 대장암보다 많이 발견되었다. 고령이거나 세망세포비가 높을수록 출혈 연관 병변을 가지고 있는 경향이 있었다. 향후 국내 실정에 맞는 철결핍 빈혈 관련 위장관 질환의 예측인자를 찾기 위한 대규모 전향적 연구가 필요하다. Background/Aim: Gastrointestinal blood loss is the most common cause of Iron Deficiency Anemia (IDA) in men and postmenopausal women. Thus, esophagogastroduodenoscopy and colonoscopy are widely used to examine the gastrointestinal tract, in search for the cause of IDA. The purpose of this study was to identify clinical and biochemical variables that predicted the outcome of endoscopic findings in patients with IDA. Methods: Patients diagnosed as IDA from 2001 to 2004 were referred and retrogradely analyzed using their clinical, biological, endoscopic, and histological data. Results: 78 patients (21 men, 67 women: mean age 49.3 years) with IDA were enrolled, and 28.9% of patients had bleeding-related lesions. The mean age of patients with evidence of bleeding was 54.8 years, which was significantly higher compared with 43.7 years of the non-bleeding group (p=0.026). The reticulocyte count for the bleeding-related group was 2.8%, which was also significantly higher compared with 2.0% of the non-bleeding group (p=0.002). Conclusions: The prevalence of upper GI lesions were higher than lower GI lesions. Endoscopy revealed a source of IDA in 28.9% of cases. For hospitalized patients with IDA, endoscopy should be recommended to those older than 60 years of age, and those with increased reticulocyte count. (Intest Res 2005;3:68-73)

개발행위허가제는 계획의 적정성, 기반시설의 확보 여부, 주변 경관 및 환경과의 조화 등을 고려하여 허가 여부를 결정함으로써 난개발을 방지하고 국토의 계획적 관리를 도모하는 제도이다. 그러나 개별적 행위에 대한 허가 여부를 일률적으로 규정할 수 없는 한계가 있어, 세부적인 판단 기준을 설정할 수 있는 재량권을 부여받고 있다. 이러한 재량적 특성은 복잡한 관련 법령, 운용 지원체계 미비, 추상적인 기준 등의 문제점을 가지고 있다. 이에 본 연구는 천안시를 대상으로 개발행위허가의 발생 및 분포특성 분석을 통해 시사점을 모색함으로써 국토의 계획적이고 체계적인 개발 및 관리를 도모하고자 한다. 개발행위허가 분포도를 통해 도출한 개발행위허가의 문제점은 개발이익을 목적으로 한 투기적 성격의 개발행위 우려, 도로·상하수도 등의 기반시설 설치의 미비, 공장의 개별입지로 인한 난개발 우려로 도출하였다. 이에 관계전문가들의 자문 및 다중적 검토 절차 도입과 법령·운영지침의 정비 및 구체화를 통한 제도개선방안을 제시하였다. 따라서 개발행위허가제의 본래 목적인 난개발 방지와 국토의 계획적 관리를 도모하기 위해서는 단순한 지표로써 허가 여부를 판단하는 것이 아닌 합리적인 토지이용 및 도시계획적 측면을 고려한 계획적 개발행위를 유도할 수 있는 제도적·행정적 개선을 시사하는 바이다. The development activity permit system is a system that prevents reckless development and promotes planned management of the country by deciding whether to grant permission in consideration of the adequacy of the plan, whether to secure infrastructure, and harmony with the surrounding landscape and environment. However, there is a limitation in that it is impossible to uniformly stipulate whether to permit individual actions, so discretion to set detailed criteria for judgment is granted. These discretionary characteristics have problems such as complex related laws, insufficient operation support systems, and abstract standards. Therefore, this study aims to promote planned and systematic development and management of the national territory by seeking implications through the analysis of the occurrence and distribution characteristics of development permits in Cheonan-si. The problems of development behavior permission derived through the distribution chart of development behavior were derived from concerns about speculative development activities for development profits, lack of infrastructure installation such as roads and sewage, and concerns about reckless development due to individual locations of factories. Accordingly, a plan to improve the system through the introduction of advisory and multiple review procedures by related experts and the maintenance and concreteness of laws and operating guidelines was presented. Therefore, the development activity permit system does not simply determine whether to grant permission as an indicator, but suggests institutional and administrative improvements that can induce planned development activities considering reasonable land use and urban planning aspects.

N/A Background/Aims: Recent surgical techniques have enabled surgeons to undertake radical operations for a much wider range of liver diseases, but the invasive nature of such operations requires that they be followed up by careful and intensive postoperative management. Since the introduction of the oxidation-reduction(redox) theory in the beginning of 1980s, the significance of the arterial ketone body ratio(acetoactate/g-hydroxybutylate), which reflects hepatic mitochondria] oxidation-reduction potential, has been discussed as one of the metabolic parameters of organ failure. The aim of this study was to assess the significance of arterial ketone body ratio as an early prognostic indicator in liver surgery. Methods: In this study, arterial ketone body ratio and total ketone body concentration were serially measured in 83 patients who underwent liver resection in the department of surgery of Youngnam University Hospital between May 1992 and Feburary 1994. Results: At the postoperative 1 day, arterial ketone body ratio was significantly higher in successful recovery group(n=71, 1.22 0.59) than that of the postoperative complication and mortality group(n=12, 0.66 l 0.34). And patients were classified into three groups by the decrease of ketone body ratio in the postoperative 1 day: group A(70 cases) with ketone body ratio above 0.7, group B(12 cases) between 0.7 and 0.4, and group C(1 case) below 0.4. In group A, 63 patients(90%) were recovered, 6 patients complicated and 1 patient dead. In B group, 8 patients(66.6%) was recovered, 2 patients complicated and 2 patients dead. The only patient of group C(100%) was dead. Conclusions: Postoperative AKBR is useful as an early prognostic indicator in liver surgery, and maintenance of AKBR above 0.7 is crucial to obtain a good surgical outcome.

Purpose: This study is conducted to investigate the relationships among sports commentators’ attributes, media engagement, and continuous watching intention in consideration of the new media platform era. Method: The survey was conducted on 350 viewers who watched the KBO league online more than once using the Google questionnaire. Of the 350 questionnaires collected, 26 inappropriate questionnaires were excluded, and 324 copies were selected as the final valid sample and used for data processing. Results: First, as a result of examining the relationship between sports commentators’ attributes and media engagement, it was found that among the sub-factors of commentators’attributes, professionalism had a negative effect on media engagement, and reliability had a positive effect. Moreover, attractiveness and technology & smart did not appear to affect media engagement. Second, media engagement was found to have a positive effect on the intention of continuing watching. Conclusion: It is necessary to find a way to make viewers more immersed in sports commentators’ commentary, and ultimately, it is reasonable to think that how to elicit a high level of immersion and empathy for viewers affects actual ratings.

송봉근,전용철,김선애,심안나,성기문,이언정,Song, Bong-Keun,Jeon, Yong-Cheol,Kim, Sun-Ae,Shim, An-Na,Seong, Kee-Moon,Lee, Eon-Jeon 대한약침학회 2011 Journal of pharmacopuncture Vol.14 No.3

Objectives : Gliosis becomes physical and mechanical barrier to axonal regeneration. Reactive gliosis induced by middle cerebral artery occlusion is involved with up-regulation of CD81 and GFAP (Glial fibrillary acidic protein). The current study is to examine the effect of the Angelica gigas Nakai(intravenous injection. 100 mg/kg twice in a day) on CD81 and GFAP of the rat in the brain after middle cerebral artery occlusion. Methods : Cerebral infarction was induced by middle cerebral artery occlusion. And after intravenous injection of water extract of Angelica gigas Nakai, the size of cerebral infarction was measured. Examination of optical microscope were also used to detect the expression of CD81 and GFAP in the brain of the rat. Results : The following results were obtained : We found that size of cerebral infarcion induced by MCAO (Middle Cerebral Artery Occlusion) in rats were decreased after intravenous injection of Angelica gigas Nakai. We injected the extract of Angelica gigas Nakai to the MCAO in rats, and the optical microscope study showed that Angelica gigas Nakai had effect on protecting the cells of hippocampus. We found that GFAP, CD81 and ERK of the brain in rats with cerebral infarction after MCAO were meaningfully decreased after intravenous injecting Angelica gigas Nakai. We found that c-Fos expression of the brain in rats with cerebral infarction after MCAO were significantly increased after intravenous injecting Angelica gigas Nakai. Conclusions : These results indicate that Angelica gigas Nakai could suppress the reactive gliosis, which disturbs the astrocyte regeneration in the brain of the rat with cerebral infarction after MCAO by controlling the expression of CD81 and GFAP. And the effect may be modulated by the up-regulation of c-Fos and ERK.

A psoas abscess (PA) is a rare clinical entity but is potentially serious condition which presents diagnostic and therapeutic challenges. The diagnosis is frequently delayed due to its variable and nonspecific features and occult clinical course. The delay in diagnosis and treatment of PA is the major poor prognostic factor. We describe herein a case of the sterile psoas abscess complicating Cronh`s disease which presented as hip flexion contracture. A 29-year-old man, at remission stage of CD involving ileocolic segment, was admitted due to pain from hip contracture. He had no bloody diarrhea and no abdominal pain. PA was confirmed by abdominal ultrasound. PA with hip contracture was completely treated with surgical excision, irrigation, drainage, and antibiotics. PA was sterile and there was no evidence of a fistulous communication from the bowel. Once suspected, aggressive diagnostic work up and definitive operative intervention is needed.

Intestinal tuberculosis is a common disease of extrapulmonary tuberculosis and should be differentiated from the inflammatory bowel diseases and malignancy such as Crohn`s disease, ulcerative colitis, amebic colitis, and colon cancer. Most frequently involved sites (75% of cases) are the terminal ileum and cecum. Other sites of involvement, in order of frequency, are ascending colon, jejunum, appendix, duodenum, stomach, esophagus, sigmoid colon, and rectum. Intestinal tuberculosis simultaneously involving the stomach and colon has been very rarely reported. Recently, we experienced a case of synchronous gastric and colonic ulcers with granulomatous inflammation. Although we did not find acid fast bacilli and the culture test was negative, empirical anti-tuberculosis therapy resulted in dramatic clinical and endoscopic improvement. We report a rare case of multifocal gastrointestinal tuberculosis with a review of literature. (Korean J Gastroenterol 2008;52:320-324)
