목적: 골 육종, 연골 육종은 흔한 질환이 아니므로, 일차 진료 현장에서 명확한 진단이 신속히 이루어지지 않고, 진단의 지연이나 오진으로 인해 문제를 야기할 수 있다. 따라서, 상기 질환에 대한 초기 증상과 임상적 특징을 조사하여 이를 확인하고, 조기 진단에 도움을 주고자한다. 대상 및 방법: 본원에서 진단된 골 육종이나 연골 육종 환자로, 기록 검토와 설문지 조사가 가능한 139명을 대상으로 하였다. 골 육종 환자가 108명, 연골 육종이 31명이었고, 남자가 86명, 여자가 53명이었으며, 평균 연령은 골 육종이 20.2세, 연골 육종이 42.4세이었다. 결과: 병원을 방문하게 된 초기 증상은 두 질병 군 모두에서 동통이 가장 많았는데, 골 육종은 101명(93.5%), 연골 육종은 19명(61.3%)이었다. 이들 중 골 육종의 49명(48.5%), 연골 육종의 1명(5.3%)에서 통증이 외상과 관련되어 시작되었으며, 야간 동통이 골 육종의 77명(76.2%), 연골 육종의 11명(57.8%)에서 있었다. 처음 방문한 진료 기관에서 악성 골 종양으로 진단된 경우는 골 육종에서는 66명(61.1%), 연골 육종에서 20명(64.5%)이었고, 오진된 경우는 골 육종에서는 골절로 본 경우가 18명(16.7%)으로 가장 많았으며, 연골 육종에서는 골 감염으로 본 경우가 6명(19.4%)으로 가장 많았다. 초진 시에 방사선 촬영을 시행한 경우 골 육종과 연골 육종 모두에서 진단율이 유의하게 높았고(p=0.009, p=0.014), 성인 군에서의 진단율이 높았다(p=0.037). 연골 육종에서 골 육종보다 환자와 의사에 의한 지연이 모두 길었다. 진단의 의사 지연을 길게 하는 요소로는 초진 시에 단순 방사선 사진을 촬영하지 않는 것과 골반 등 축성골에 종양이 위치하는 것이었고, 외상과 미성년 환자는 진단의 환자 지연을 단축시킬 수 있는 요소로 파악되었다. 결론: 악성 골 종양의 조기 진단을 위해서는 외상이나 야간 동통 등의 병력 청취를 소홀히 하지 않아야 할 것이며, 초진시의 단순 방사선 촬영과 주기적인 경과 관찰 및 방사선 사진의 비교 등으로 조기 진단의 정확성에 힘써야 할 것이다.
체외충격파치료술(Extracorporeal Shock Wave Therapy, ESWT)은 보존적인 치료가 어려운 근골격계 난치성 통증 치료 뿐 아니라 심혈관계 질환까지 적용 분야가 확대되고 있는 혁신적인 치료술이다. 본 연구에서는 국내에서 사용되는 집속형 ESWT 치료기의 성능을 결정하는 충격파 음향 출력의 분포를 조사했다. 분석에 사용된 데이터는 식약처에 등록된 30개 기술 문서를 통해 수집했다. 조사 결과, ESWT 치료기 충격파의 집속 특성은, 초점 거리가 5 mm ~ 65 mm, 초점 폭이 3 mm ~ 30 mm, 초점 깊이가 4 mm ~ 108 mm 범위에서 변화하고 있다. 충격파의 최대 양압(P+)는 7 MPa ~ 280 MPa, 초점에서 에너지 밀도 Energy Flux Density(EFD)는 0.0035 mJ/㎟ ~ 35 mJ/㎟, 펄스당 에너지(E)는 0.737 mJ ~ 80.86 mJ로 매우 넓은 범위에서 분포하고 있다. P+ 및 EFD 상관성 분석에 포함된 모든 국내산 PE 방식 제품(5개) 및 1개의 EM 방식 국산 치료기는 P+ 및 EFD가 통상적인 범위를 크게 벗어나고 있으며, 예상되는 상관성을 따르지 않고 있어, 데이터의 신뢰성을 인정하기 어려운 상태이다. 음향 출력의 값에 신뢰성을 부여하기 어려운 경우, 식약처에서 인정하는 시험 검사 기관을 통해 사후 시험 검사 및 관리가 요구된다. 충격파 음향 출력에 대한 통과 기준이 치료기의 적응증에 대한 임상 시험 결과를 근거로 설정될 수 있도록 식약처의 규정 및 가이드라인 개선이 필요하다.
Objectives : Smilacis glabrae rhizoma (SG) has been traditionally used as a herbal medication of musculoskeletal disorders like arthritis, pain, convulsions, and syphilis in traditional Korean medicine. This study was investigated anti-oxidative and anti-inflammatory effect of fractionated extracts of Smilacis Glabrae Rhizoma in Human Umbilical Vein Endothelial Cell (HUVEC). Methods : SG extract prepared with methanol, and then fractionated with hexane, dichloromethane, ethylacetate, n-butanol and water. Inhibitory effect of SG onto free radical generation was determined by measuring DPPH, superoxide anions and nitric oxide scavenging activities in vitro. Cytotoxic activity of extracts on RAW 264.7 cells was measured using 5-(3-caroboxymethoxyphenyl)-2H-tetra-zolium inner salt (MTS) assay. Intracelluar oxidation was analysed by DCF-DA assay. The nitric oxide (NO) production was measured by Griess reagent system. The levels of ICAM-1 and VCAM-1 expression were confirmed by western blot. And proinflammatory cytokines were measured by ELISA kit. Results : Our results indicated that fractionated extracts, especially ethyl acetate (EA) extract, significantly inhibited free radical generation, the TNF-
According as the automation of clerical work(OA ; Office Automation) develops, the use of VDT(Visual or Video Display Terminal) is increasing suddenly. But, in proportion to the spread of office automation(OA tendency), the self-conciousness syptom attendant upon the work is appearing also (Kim, Jung Tae, Lee, Young Ook, 1990). The apparatuses of office enable the clerical workers to be convenient and perform mass businesses. But, they are increasing the opportunity to be exposed to VDT syndrom, techno stress, computer terminal disease, pain by muscle strain(RSI), bradycausia of noise nature, and electromagnetic waves, etc. which are referred to as the new type of occupational diseases to the workers. It is the real situation that the workers to use VDT is complaining of the physical inconvenience sense in the recent newspaper and literature, it is the point of time that the sydrome to come from VDT use and computer terminal disease, etc. must be classified into the occupational disease(Lee, Kwang Young 1990, Lee, Kyoo Hak 1990, Lee, Won Ho 1991, Lee, Si Young 1991, Lee, Joon 1991, Choi, Young Tae 1991, Heo, Seung Ho 1989). In addition, it is the real situation that the scientifitic study result about the scope that electromagnetic waves has influence on the human body has not been suggested yet, and criticism on the stable exposure permission standard about electromagnetic waves to be emitted from VDT and on the problem in the health about electromagnetic waves is continuing. (IEEE Spectrum, 1990). In addition according to the experience of nursery business of industry field, it is the real situation that the patients who consult complaining of physical and mental inconvenience sence, among the users of apparatus of office automation, are reaching 10% of the patients coming to doctor's room. Therefore, it is necessary to confirm the self-consciousness symptom that the clerical workers complain of multilaterally with the actual state examination about the use of the apparatuses of offices automaton. Thus, this study was tried as th basic data for the cosultation and education for the maintenance and furtherance of the health of workers as the nurse of industry field, by confirming the contents of self-consciousness symptom attendant upon the use of the apparatus for office outomation making the financial institution in which the spparatus for office automation in most frequently used as the subject, and by examining whether there is the difference according to the subject of study, the data were collected, by using the questionnaire method, making 200 workers who consented to the study participation as the subject, among the persons who have spent over 3 months since they used the apparatuses for office automation and didn't receive the treatment in hospital due to the clerical disease for recent 3 years. The period of data collection was from Oct. 9, 1991 to Oct. 12. As for the measurement instrument about the complaint if self-consciousness symptom attendant upon the use of apparatuses fo office automation, the question item on the complaint symptom of health problem attendant upon the treatment of VDT that Kim(1991) developed and on CMI health problem and the question items on the fatigue degree due to industry were used by previous examination to 25 persons. Collected data were analyzed with the statistical method such as percentage, arithmetic mean, Person correlation coeffient, Kai square verfication, t-test, ANOVA, etc. by using SPSS/PC+ program, and the result is as follows : 1. The self-consciousness symptom that the clerical workers complained of most frequetly appeared high in 'My eyes are tired'(99.4%), 'I feel fatigue and weariness'(99.4%), 'I feel that my head is heavy5(90.0%), 'eyesight fell'(88.8%), 'I have a stiff neck'(88.8%), 'I fell pain in the shoulder'(85.0%), 'I feel cold and painful in the eyes'(76.9%), 'I feel the dry sense of eyeball'(76.2%), 'My nerves are edgy, and I an fretful, (75.6%), 'I feel pain in the waist'(73.2%) and 'I fell pain in the back'(72.8%). It emerged that the subject use the apparatuses for office automation complained of self-consciousness symptoms related to visual symptoms and musculoskeletal symptoms. 2. As for the general feature of examination subjects, the result to see the distribution by classifying into sex, age, school career, use career of apparatuses for office automation, skillfulness degree of the use of apparatus for office automation, use hours of the apparatuses for office automation per 1 day, type of business of the apparatus for office automation, rest hours during the use of apparatus for office automation, satifaction degree of business of office automation, and work circumstance, etc. emerged as follows : As for the sex of subjects, the distribution showed that men were 58.8% and women were 41.3%, Age was average 26.9. As the distribution of school career, the distribution showed that4below the graduation of high school' was 58.8%, 'graduation from junior college-university' was 35.0%, and 'over graduate school' was 6.3%. In the question to ask the existence or non-existence of experience of health consultation in connection with the work of office automation, the response that I had the consultation exprience and I feel the necessity emergerd as 90.1% And, the case that the subject who didn't wear the glasses or lens before using the OA apparatus wear glasses or lens after using OA apparatus emerged as 28.3% of whole. As for the existence or non-existence of use career of OA apparatus, the case under 3 years was highest as 52. 7%. As for the skillfulnness degree about the use of apparatus for office automation, most of them are skillful with the fact that 'common' was 44.4%, 'skill' was 42.5%, and 'unskillful' was 13.1% As for the use average hours of the apparatus for office automation per 1 day, the distribution showed that the case under 3-6 hours was 33.1%, the case under 6-9 hours was 28.1%, the case under 3 hours was 30.6%, and the case over 9 hours was 8.1% Main OA business and the use hours for 1 day showed in the order of keeping and retrieval, business of information transmission(162min), business of information transmission(79.3 min), business of document framing(55.5 min), and business of duplication and printing(25.4min). as for the rest during the use of apparatus for affice automation, that I take rest occasion demands the major portion, but that I take after completing the work emerged as 33.8%. Though the subiness gets to be convenient by the use of the apparatus for of office automation, respondents who showed the dissatisfaction about the present OA business emergd high as 78.1%. The work circumstances of each office was good with the fact that the temperature of office was 21.8, noise was average 42.7db, and the illumination was average 364.4 lx, in the light of ANSi/HFS 100 Standard. 3. Sight syptom, musculoskeletal symptom, skin and other symptoms showed the significant difference according to the extent of skillfulness of the apparatus for office automation. All the symptoms exept skin symptom showed the difference according to the use hours of the apparatus for office automation. All the question items exept the sytoms of digestive organs and the rest hours during the apparatus for office automation showed the signicant difference. The question item which showed the signicant difference from the satisfaction degree of present OA business showed the significant difference from all the question item classified into 6 groups. But, age and school career didn't significant difference from the complaint of any self-consciousness symptoms.
