      • 흰쥐에서 음경발기 평가의 척도로서 음경해면체내압측정술 확립

        송윤섭,김용준,이광우,김준모,문기혁,박영호,민영기,유형균,김형건 순천향의학연구소 2001 Journal of Soonchunhyang Medical Science Vol.7 No.1

        Purpose: Because studies about the control of penile erection at the entral nervous system was dependent on the animal experiments, establishment of measuring penile erection is important to evaluate the effects changes at the central nervous system on the penile erection. Intracavernous pressure measurement in rats has been introduced as a suitable index for the evaluation of penile erection but this method is invasive and technically difficult. So, we established the intracavernous pressure measurement in rats as the experimental index for penile erection. Materials and Methods: 42 male adult Sprague-Dawley rats (250-300gm) were divided to saline or papaverine treated group. Rats were placed on a heating table to maintain their body temparature and anesthetized with 50mg/kg of pentobarbital sodium by intraperitoneal injection. A cannula was inserted to the left carotid artery to measure systemic blood pressure. Saline (0.05, 0.1ml), papaverine(0.05, 0.1, 0.25, 0.5, 1.0, 2.0mg) were injected intracavernously via 26 guage needle filled with saline or papaverine which connected to pressure transducer and polygraph was inserted into the corpus cavernosum on one side to inject the drug and to measure intracavernous presure. Results: Properly executed insertion and intracavernous administration produced a instantaneous but transient rise in intracavernous pressure that substantially stabilized and maintained at 5.4±0.4mmHg. Intracavernous pressure and duration of penile blood flow following intracavernous injection of papaverine are increased comared to those of saline. Conclusions: Monitoring intracavernous pressure in rats represents a suitable index for the evaluation of penile erection in small laboratory animals.

        연구목적 : 본 연구는 전산화 평가도구를 개발하고, 신뢰도와 타당도를 검증하며, 표준화 자료를 얻기 위하여 수행되었다. 방 법 : 숫자 따라하기검사, 시각 단기기억력검사, 한글언어청각학습검사, 시각도형학습검사를 전산화하였으며, 27명의 정상인을 대상으로 하여 검사-재검사 신뢰도를 검증하였다. 타당도를 검증하기 위하여 48명의 정상인을 대상으로 검사 성적을 기존의 인지기능 검사 성적과 비교하였으며, 또한 본 연구에서 개발된 검사들의 내적 일치도를 평가하였다. 20세부터 50세까지 고졸이상의 학력을 가진 한국 남녀 성인 150명을 대상으로 표준화 자료를 얻었다. 결 과 : 전산화 기억력 검사들의 검사-재검사 성적은 paired t-test 결과 차이가 없었으며, Pearson 상관계수 0.405∼0.873의 높은 상관관계를 보였다. 숫자 따라하기검사, 시각 단기기억력검사, 언어청각학습검사는 기존의 지필 혹은 전산화 검사 결과와 높은 상관관계를 보였다. 시각도형학습검사는 유용한 검사이나, 향후 방법론적 개선이 필요한 것으로 생각된다. 전산화 기억력 검사 성적은 학력이 높을수록 우수하였으며, 성별과 연령도 결과에 영향을 미쳤다. 전산화 기억력 검사의 표준화 자료와 해석기준을 제시하였다. 결 론 : 20세부터 50세까지 고졸 이상의 학력을 가진 한국 성인 남녀에서 신뢰성 있고 타당성 있게 사용할 수 있는 전산화 언어 및 시각 기억력 검사도구가 개발되었으며, 표준화 자료와 해석기준이 마련되었다. Objectives : This study was conducted to develop the computerized memory tests for Korea adults. It also aimed at evaluating the reliability and validity of these tests and providing their normative data. Methods : Computerized versions of digit span, visual span, auditory applications and correction. The test-retest reliabilities of each test was evaluated by the paired t-test and Pearson's correlation coefficient using the data from 27 normal persons. The validity of each test was evaluated by the Pearsons's correlation coefficient between the computerized test scores and the pre-existing cognitive function tests using the data from 48 normal persons. The normative data were obtained from the 150 Korean adults, age 20 to 50, whose educational levels were higher than high school graduate Results : There were no statistical difference between the means of the test and retest scores. High correlations were also observed between the tests and the retest scores(r ranged from 0.405 to 0.873). The computerized digit span, visual span, and auditory verval learning tests scores were highly correlated with the pre-existing memory measures. The computerized memory test scores were greatly influenced by the educational level. The visual learning test seems useful, however, it requires methodological refinement. The normative data and guidelines for interpretation were provided. Conclusions : Clinically applicable computerized memory assessment tools with high reliability and validity were developed. The normative data for the Korean adults aged 20 to 50 were obtained and the guidelines for the interpretation were provided.

        원형섭,황성연,박정배,이준형,박철완,이근 대한응급의학회 1996 대한응급의학회지 Vol.7 No.2

        It has been known that sternal fracture increases the risk of potentially life-threatening injuries, such as myocardial, pulmonary, and thoracic vascular injuries, and it has 25% to 45% of mortality, primarily resulting from these underlying injuries. The authors reviewed retrospectively the medical records and radiographic findings of the patients who admitted with sternal fracture at Chung Ang Gil Hospital from 1 June 1994 to 31 December 1995 to evaluate the significance and clinical course of sternal fracture. The results were followings: 1. The male to female ratio was 3:2 and the mean age was 43.1 and 45.4 years old in male and female, respectively. 2. Motor vehicle occupant accident was the most common cause of sternal fracture. 3. Of 33 cases, there was no death, but common associated injuries which were rib fracture, hemothorax, lung contusion, vertebral fracture, penumothorax, long bone fracture, myocardial contusion, flail chest, facial chest, facial bone fracture, and pericardial effusion, in order. 4. The clinical course of sternal fracture was determined primarily by associated injuries except for communited sternal fracture. 5. The patients with isolated sternal fracture, who had an otherwise normal chest x-ray, normal electrocardiogram, no other significant associated injuries and are hemodynamically stable, had a benign clinical course.

        신준섭,최옥경,정구영 대한응급의학회 1996 대한응급의학회지 Vol.7 No.2

        Paraquat(1,1-dimethyl-4,4-bipyridium dichloride) is lethal herbicide and it is thought to act by turning into superoxide and peroxide free radical in the presence of reducing agents. Among the multiple organ failure, the pulmonary complication is always fatal. We present the case of a patient with subcutaneous emphysema and pneumomediastinum without pneumothorax on 6days later after acute paraquat ingestion. A 28 years old female patient was admitted ED at 10:40 on September 8, 1995(Day 1) after ingestion of 10cc-15cc of paraquat (20% solution) at 20:00 on yesterday. By the sodium dithionite test, the presence of paraquat was negative in the urine. She was alert without oropharyngeal ulceration and had stable vital signs. Her hepatic function was moderately deteriorated (SGOT/SGPT 389/867, ALP 233, TB 5.7) and the others laboratory findings were normal limits. She was transferred to ICU and treatment was according to a our protocole(Table 1). On day 6, she complainted numbness on the right lateral neck and respiratory difficulty. The chest X-ray showed subcutaneous emphysema, pneumomediastinum and pneumomediastinum without pneumothorax. Day after day, the size of subcutaneous emphysema and pneumomediastinum were decreased on chest x-ray and it was not found inflammatory signs. The chest CT showed pulmonary fibrosis on the both lower lung field(onday 10) and the esophagography showed no specific findings without dye leakage(on day 14). On day 16, The high resolution chest CT was showed diffuse pulmonary opacity with cystic lesions and peribronchovascular air densities were found with pericardial emphysema and pneumomediastinum. At 4:30 a.m. on day 18, the respiratory arrest was developed and she was expired at 4:35 a.m. under DNR.
