연구목적: 정신과 전문병원에 입원해 있는 만성정신분열병 환자들을 대상으로 첫째 지연성 운동장애의 유병율과 위험인자들을 조사하고, 둘째 지연성 운동장애와 정신분열병의 음성증상 및 인지기능 장애와의 상관성을 조사하고자 한다. 방법: 연구대상자는 마산동서병원에 입원 중인 환자 중 DSM-IV의 정신분열별 진단기준에 부합하며, 최근 3개월 이상 동일 용량의 항정신병약물 복용한 271명(남자 174명, 여자 97명)의 환자들이었다. 지연성 운동장애에 대한 평가는 Abnormal Involuntary Movement Scale(AIMS)을 이용하였고, DSM-IV와 Sc-hooler와 Kane(1982)의 진단기준 양자에 부합하는 환자들만을 지연성 운동장애군으로 분류하였다, 정신 분열병 정신병리에 대한 평가는 Brief Psychiatric Rating Scale(BPRS)와 Schedule for the Deficit Syndrome(SDS)을 이용하였고, 인지기능에 대한 평가는 Mini-Mental Status Examination(MMSE)을 이용하였다. 결과: 지연성 운동장애의 유병율은 50.9%이었고, 50세 이상, 남자에서 높았다. 그러나 입원기간과 항정신병 약물의 일일 사용량에 따른 차이는 없었다. 지연성 운동장애의 호발부위는 혀, 상지, 입술과 입 주위의 순이었다. BPRS 총점 및 소항목 척도점수와 SDS 척도점수는 지연성 운동장애의 유무에 따른 차이가 없었다. MMSE 총점 및 소항목 점수도 지연성 운동장애의 유무에 따른 차이가 없었다. 결론: 평균입원기간이 9년 이상인 만성정신분열병 환자들에게서의 지연성 운동장애의 유병율은 50.5%이었고, 연령이 가장 의미있는 위험인자임을 확인했다. 만성정신분열병 환자들이 주 대상인 본 연구에서는 지연성 운동장애와 정신분열병의 음성증상 및 인지기능 장애와의 상관성은 입증하지 못했다. Objectives: The purpose of present study was to determine the prevalence rate of tardive dyskinesia and to search for its risk factors in chronically institutionalized schizophrenic subjects. We also examined the relationship between tardive dyskinesia and both negative symptoms and cognitive impairments in the same subjects. Methods: Subjects were 271 in-patients(174 males, 97 females) at Masan Dongsuh Hospital. They met DSM-IV criteria for schizophrenia and had been taking fixed doses of antipsychotics for at least 3 months. Tardive dyskinesia was assessed by Abnormal Involuntary Movement Scale(AIMS). Cases of tardive dyskinesia were ascertained by the criteria of Schooler and Kane (1982) and DSM-IV. The rating of psychopathology was acquired using Brief Psychiatric Rating Scale(BPRS) and Schedule for the Deficit Syndrome(SDS) and the assessment of cognitive function using Mini-Mental State Examination(MMSE). Results: The prevalence of tardive dyskinesia is 50.9% and the frequency of tardive dyskinesia was high est in male above the age of fifty. But there was no statistically significant relationship between the frequency of tardive dyskinesia and both the length of hospitalization and the daily dose of antipsychotics. The frequency order of abnormal movement in the patients with tardive dyskinesia was as follows : tongue, upper extremities, lips and perioral area. We couldn't find any significant difference in the total and subscale scores of BPRS between the groups with and without tardive dyskinesia. There were no differences in MMSE scores between the groups with and without tardive dyskinesia. Conclusion: This study gave us that the prevalence of tardive dyskinesia was high in chronically institutionalized schizophrenic inpatients and that age was the most significant risk factor of tardive dyskinesia. The relationship between tardive dyskinesia and both negative symptoms and cognitive impairment, however, was not revealed.

A facultative anaerobe Enterococcus faecium 19-46-4 was used to study the production of an antimicrobial substance in anaerobic conditions. Major part of the antibiotic activity was found in the culture filtrate of the bacterium. The active compound was extracted by an equal volume of iso-butanol and concentrated in vacuo (at 50℃) before purification by C-18 liguid column chromatography and HPLC. A chromatographically pure compound was obtained by two passages of HPLC columns, The compound appeared as a pale-yellow powder. The yield was about 2.5 mg l^-1 culture filtrate. The compound was named as KIST 194. KIST 194 were identified as cholic acid (3α, 7α, 12α-trihydroxy-5β-cholan 24-oic acid) based on its physico-chemical properties determined by UV, IR, ^1H-NMR, ^13C-NMR, EI-MS and LC-MS.

건이행술

상지의 말초신경 손상에 의한 건이행술은 수술 전의 전제조건으로 구축에 의한 조직의 변형을 먼저 교정하여야 하고, 건이행술을 시책할 시기에는 관절들이 수동적으로 정상에 가까운 운동성이 있어야 하며, 건이행의 방향을 가능한한 직선이 되게하여야 한다. 이행건의 선택은 건이행술을 받는 근육과 비슷한 힘과 excursion을 갖는 공력근을 선택하여야 하며, 또한 neuropraxia등에 의해 일시적으로 마비가 왔다가 그 기능이 회복되었더라도 이러한 근육은 건이행술에 사용하여서는 안된다. 수술시기는 손상 받은 신경의 종류, 신경봉합의 방법, 연부조직 및 골조직의 상태에 따라 다르므로 경우에 따라 적절한 시기를 선택하여야 한다. 수술 후 처치는 단순 건봉합의 경우와는 달리 좀 더 세심한 관찰이 요하며, 적절한 보조기 착용과 물리치료가 필요하다.

EMS하의 유럽공동통화정책 성과분석

정철호,강영훈 釜山外國語大學校國際通商硏究所 2002 國際經營論集 Vol.17 No.-

In this study I investigated the stability of the EMS during the period of 1979-1998 and gave several suggestions to the single currency of the EU. In this study, several conclusions are reached: First, the EMS succeeded in creating a monetary stability zone but if compared to the volatility of the Bretton Woods System in the 1960s, the exchange rate in EMS were found to be more volatile. Second, at a glance it might appear that the EMS was very successful with regard to the internal dimension. Average inflation within the system decreased from about 10 percent in 1979-1980 to 2 percent in 1987. But it increased to about 4 percent throughout the 1989-1990 period. Comparing inflation rates of other countries, such as the USA and Japan, to those of EMS members, the disinflation effect can be found to some extent during the early period of EMS. Especially, inflation rates of EMS members were higher than during the Bretton Woods era. Thirdly, the shock absorbing function was not effected by the EMS. National monetary policy always has had spillover effects on other countries. These external effects made a coordination of monetary policy desirable, but an explicit coordination might be difficult to be achieved. A large asymmetric shocks and a different specialization would tend to cause partial exchange rate coordination. Therefore, it is implied that the EMS is not a useful substitute for full coordination. Finally, the most direct way to measure the degree of asymmetry in a fixed exchange rate system is to assign the obligation to intervene in the foreign exchange markets to the EU members. The EMS was designed to be symmetric in this respect, since both central banks have to intervene if any one bilateral exchange rate reaches the limits imposed by the parity grid. Especially the Bundesbank intervened only if it was obliged to do so by the main symmetric feature of the EMS, that is, the obligation to control at the margin. This analysis tells us that the EMS has not functioned as initially intended. Most EU members employed their own policy targets. Accordingly, the bilateral exchange rates of EU members in the EMS were volatile and went beyond the margins. And, the original intention ito stabilize exchange rates of members included at the early period of the EMS did fade away. In conclusion, EU members realized that the fixed exchange rate system did not guarantee for the stability of exchange rates in the internal degree and, therefore, led to the decision to introduce the single currency.

Adult polycystic kidney disease(APKD) usually accompanies with renal and extrarenal manifestations and liver cysts are present in aproximately 30% of patients with APKD. Kidney cysts often accompany with hemorrhage, rupture, infection, however, liver cysts are usually asymptomatic and do not impair liver function. Rare complication of liver cysts in patient with APKD include portal hypertension with bleeding esophageal varices and hepatic failure with encephalopathy. But, in APKD patient, infection of liver cysts without infection of renal cysts is extremely rare. We report a case of infected liver cyst in a patient with APKD who has complained generalized abdominal pain and high fever which was confirmed by ultrasound and aspiration. The patient was treated successfully with repeated aspiration and systemic antibiotics.

Renal ischemia is one of the most common causes of acute renal failure. Four factors related to the pathogenesis of acute renal failure are vasoconstriction, decreased glomerular filtration rate, tubular back leak of filtrate, and intratubular obstruction. The cellular response to renal ischemic insults include decreased content of adenosine trihosphate, lipid peroxidation induced membrane degradation, alteration in cellular pH, and calcium or phospholipase induced mitochondrial dysfunction. Much attention has been given to the role of increased cellular calcium as a pathogenetic contributor to cell injury during ischemia. Author studied the protective effects of calcium antagonists on cellular injury during renal ischemia in rat. To investigate the protective role of these agents, author measured the amount of malondialdehyde(MDA) and the enzyme activities of free radical scarvengers-superoxide dismutase(SOD), catalase and glutathione peroxidase from non-pretreated group and calcium antagonists pretreated groups in control, ischemia and reflow subgroups. The results were summerized as follows: 1) The amount of MDA in non-pretreated group was higher in the reflow compared with the control(<p<0.01). But, in all pretreated groups, there was no statistically difference in the amount of MDA. 2) The SOD activity in non-pretreated group was lower in both the ischemia and the reflow compared with the control (P<0.05). But, in both verapamil and trifluoperazine-pretreated groups, there was no statistically difference in the SOD activity. 3) Both catalase and glutathione peroxidase activities in non-pretreated group were lower in both the ischemia and the reflow compared with the control (P<0.05). But in all pretreated groups, there was no statically difference in both catalase and glutathione peroxidase activities. These results suggest that free radical mediated ischemic injury by renal artery clamp in rat can be protected by intraperitoneal pretreatment with calcium antagonists. As trifluoperazine has a protective effect in renal ischemia, the calcium activated calmodulin dependent enzyme may play a role in renal ischemic injury.

Five items among neurobehavioral core test battery of World Health Organization, including Santa Ana dexterity, pursuit aiming, digit symbol, simple reaction time, and Benton visual retention, were administered to the workers occupationally non-exposed to neurotoxic agents by operational guide for the WHO neurobehavioral core test battery. Subjects were volunteers from the industrial workers(117) and clerks(40). Detailed occupational history such as exposed agents including noise or vibration, educational level, residence, smoking and drinking habit were recorded. Most of the neurobehavioral tests were correlated with age and educational level. Smoking was correlated with pursuit aiming and digit symbol. Vibration affected pursuit aiming. Job type(industrial workers vs. clerks) and noise exposure did not affected among tested items. Multiple regression analysis was done for establishing predict equation to estimate normal ranges of the tests for male workers. Age was shown to be main independent variable affected for all tests except wrong dot of pursuit aiming. Educational level was also shown to affected most of the tests except Santa ana dexterity and wrong dot of pursuit aiming. Alcohol consumption affected Santa Ana dexterity, non-preferred hand, and smoking affected only wrong dot of pursuit aiming after multiple regression analysis.

This study was carried out to assess of knowledge(K). attitude(A) and practice(P) on general health risk factors in small and medium scale industry workers in Kimpo area. We used self-administered questionnaire regarding the physical exercise, smoking, drinking, intake of fatty diet, mental stress, diet habit, hypertension management, hepatitis, sleep, personal hygiene. The results obtained were as follows : 1. There were significant differences among age groups in attitude and practice but not significant in knowledge, and above 40 years old age group took the higest scores in KAP. 2. There were significant differences between male and female subjects on total mean scores of KAP. 3. There were not significant differences among groups in size of enterprise and work duration. 4. The white collar workers had high scores than blue collar workers but there were no significant differences on attitude and practice. 5. When stepwise multiple regression analysis was done, work status and sex were significantly attributed to knowledge, age and sex were attributed to attitude, and sex was attributed to practice, but the coefficient of determination were very low. In conclusion in small and medium scale industry workers, there were weak or no effects of age, sex, size of enterprise, work duration and work status on knowledge, attitude and practice regarding general health risk. So it suggested that the health promotion program including health education had to be carried out on all members of workers not on specific group.

교근 절개술을 이용한 관골골절의 관혈적 정복술

Open reduction with internal fixation of the displaced zygoma fractures is necessary to avoid facial asymmetry, ocular dysfunction, and masticatory impairment. Generally the tripod malar fractures have been treated with two-point fixation. But secondary malposition can develop as a result of masseter pull. Masticatory forces can both rotate and displace zygoma. So the two-point rim fixation may be indadequate to stabilize the tripod malar fracture against the tonic downward pull of the masseter muscle, especially if the thin lateral wall of the maxillary antrum has been damaged. Authors attempted to treat the tripod malar fractures with the simultaneous use of the three-point or four-point fixation and the masseter muscle myotomy at the origin. Postsurgical depression did not recur in follow-up, which was common in the standard Open Reduction and internal fixation procedures.
