연골육종은 비교적 서서히 자라며 늦게 전이하는 악성 연골 종양으로 알려져 있다. 골 연골종에서 발생한 속발성 연골육종은 발생빈도는 드물며 타부위로의 전이가 적고 악성도가 낮은 경우가 많아 적합한 수술적 치료로서 좋은 예후를 보이는 것으로 보고되고 있다. 본 동국대학교 정형외과학 교실에서는 우측 대퇴골 원위부 골간단부에 생긴 고립성 골 연골종에서 이차적으로 발생한 연골육종을 치험한 바 문헌고찰과 함께 보고하는 바이다. A case of Secondary Chondrosarcoma Arising from Solitary Osteochondroma of the Distal Femur Department of Orthopaedic Surgery, College of Medicine, DongGuk University Phil Hyun Chung M.D., Jung Su Hwang M.D., Suk Kang M.D., Yang Mln Kim M.D., Hyung Ho Oh M.D., Dong Ju Chae M.D., Jong Pil Kim M.D. Chondrpsarcoma is a malignant cartilage-forming tumor that grows slowly and metastasis of this tumor occurs in late stage. Secondary chondrosarcomas arising from a solitary osteocartilaginous exostosis are rare and those have a better prognosis than other chondrosarcomas, and they rarely metastasize. We present our experience with a case of secondary chondrpsarcoma arising in solitary osteochondroma of distal metaphysis of right femur with clinical details.

오동열,서현주 大韓神經精神醫學會 1996 신경정신의학 Vol.35 No.4

본 연구는 첫째, 국립서울정신병원 입원환자의 다음증유병율과 그 측정방법에 관하여 알아보고 둘째, 다음증환자의 특성을 알아보기 위해 다음증군과 대조군의 임상특성 및 생물학적 지표를 비교하였다. 국립서울서울정신병원에 입원중인 환자 634명을 대상으로 다음의 진단 기준 (1)(2)(3)중 하나라도 만족시키는 환자를 다음증 환자로 결정하였다. (1) 치료진의 보고상 입원 중 다음증으로 인한 물중독의 삽화가 명백히 있는 경우 (2) 3회 연속 뇨비증이 1.008이하이면서 하루 3리터 이상의 물을 섭취하는 경우 (3) 3회 연속 뇨비증이 1.008이하이면서 혈중 나트륨 농도가 135mEq/L이하인 경우 위 진단기준을 만족시키는 환자는 총 24명으로 전체 환자의 3.79%였다. 다음증군 20명과 대조군 20명의 임상특성 및 생물학적 지표의 비교를 통하여 다음증 환자의 특성을알아보았다. 연구 결과는 다음과 같다. 1) 유병기간, 항정신병약물 용량, 경련, 전기경련치료, 흡연, 기타 약물 사용은 두 군간에 차이가 없었다. 2) 다음증군에서 대조군보다 뇨비증이 더 낮았고 물 섭취량이 더 많았다. 일중 체중변화(normalized diu-mal weight gain)는 두 군간에 차이가 없었다. 3) 다음증군에서는 혈중 항이뇨 호르몬(antidiuretic hormone 이하 ADH)이 정상범주에 들었으나 대조군에서는 정상범주보다 높았다. 또한 다음중군에서는 혈중능동삼투농동(osmolality 이하 Osm)가 정상범주보다 낮았으나 대조군은 정상범주에 들었다. 본연구의 결과를 전체적으로 종합한다면, 저자들의 진단기준에 따른 국립서울정신병원 입원환자의 다음증 유병율은 3.79%이며 다음증 측정방법으로 치료진의 보고, 뇨비증, 혈증 나트륨 농도, 물 섭취량의 측정 등을 제시할 수 있겠다. 그리고 다음증군과 대조군의 비교에서 유병기간, 항정신병약물 용량, 경련, 전기경련 치료, 흡연, 기타 약물 사용 등의 임상특성의 차이는 없었으나 뇨비증, 물 섭취량, 혈중 ADH와 Osm 같은 생물학적지표는 분명한 차이를 보임으로서 다음증군의 특성을 나타낸다고 할 수 있겠다. We attempted to estimate the prevalence of polydipsia in psychiatric inpatients in Seoul National Mental Hospital and to find out the identification method for polydipsic patients. We also compared the clinical and biological characteristics of polydipsic patients with those in nonpolydispic patients. Methods &Results : The following inclusion criteria were applied to the study subjects for estimating the prevalence of polydipsia among psychiatric inpatients at Seoul National Mental Hospital. 1) By staff report, that a objective clinical evidence of water intoxication during hos-pitalization was noted. 2) Three consecutive urine specific gravities were all less than 1.008 and also water intake was more than 3 liters per day. 3) Three consecutive urine specific gravities were all less than 1.008 and also serum sodium level was less than 135 mEq/L. By these inclusion criteria, we found 24 polydipsic patients among 634 hospitalized psychiatric inpatients, with the prevalence of 3.79%. Comparison of the clinical characteristics and biological determinants between 20 polydipsic and 20 nonpolydipsic patients produced the following results : 1) No differences were found in duration of illness, dosage of neuroleptics, seizure history, electroconvulsive therapy history, smoking, use of medications other than neuroleptics, between the groups. 2) There was no difference in normalized diurnal weight gain. But polydipsic patients showed more water intake and lower urine specific gravities than nonpolydipsic ones. 3) Plasma antidiuretic hormone levels were within normal range and osmolalities were lower than normal range in polydipsic patients. BUT plasma antidiuretic hormone levels were higher than normal range and osmolalities were within normal range in nonpolydipsic patients. Conclusion : The prevalence of the polydipsia was 3.79%. We suggest that staff report, urine specific gravity, serum sodium level, and oral water intake can be identification markers for polydipsta. Clincal characteristics such as duration of illness, dosage of neuroleptics, seizure history, electroconvulsive therapy history, smoking, and use of medications other than neuroleptics did not differ between polydipsic and nonpolydipsic patients. But biological determinants such as urine specific gravity, oral water intake, plasma antidiuretic hormone level, and osmolality differed beween the groups. Therefore these biological determinants could be adopted as biological markers for polydipsia.

This study focuses on Comparative of conventional Agriculture and Organic Farming Among various kinds of environmentally sound farming practices the organic and Conventional Agriculture practices are chosen for this study. The main objective of this study is to evaluate the technological systems of organic farming practice in order to find the possibility of extending such technological system to the general farmers. Compared with the general farming practices, the organic farming requires many special technologies. Among them, technologies relating to compost making, pest, insect and weed control are different from those fo general farming practices. New technologies for the improvement of organic farming practices are developed or and imported from abroad by the organic farming association. As far as technology development for the organic farming, many research organizations between the goals of technology development of the conventional and organic farming system. In other words, land productivity of the organic farming technological system is lower than that of the conventional farming technological system.

Tsutsugamushi disease is an acute febrile illness caused by Orientie. tsutsugsmushi. It is characterized by fever, myalgia, lymphadenopathy, and rash. And it can be easily diagnosed by characteristic eschar and serologic testing. Nearly all of the patients with tsutsugamushi disease improve with antibiotics such as doxycycline. However, the fatality rate of untreated cases is seven to ten percent. Splenic infarction is not common disease which is caused by occlusion of the main splenic artery or any of its branches. It is mainly caused by emboli that arise from cardiovascular disease, but sometimes by regional thrombosis associated with leukemia, myeloproliferative disorder, sickle cell anemia, pancreatitis, splenic torsion and septicemia. We experienced one case of tsutsugamushi disease with splenic infarction, which was improved after doxycycline treatment finished.

김동준,김영주,김학근,박은종,서은주,황윤찬,오원만,황인남 大韓齒科保存學會 2005 Restorative Dentistry & Endodontics Vol.30 No.3

본 연구에서는 현재 임상에서 home bleaching을 위해 사용되고 있는 표백 재료들이 치아 법랑질의 투명도에 어떠한 변화를 일으키는지 고찰해 보고자 시행하였다. 실험 대상으로는 하루 전 발거한 우치 (bovine tooth)를 사용하였다. 치아의 순면에 수직되게 다이아몬드 드릴을 이용해 수주 하에서 직경 6 mm의 원통형 치아 시편을 만들어 순면이 노출된 상태로 투명한 아크릭 레진에 포매한 후, low speed diamond saw (Isomat, Buehler Co., USA)를 사용하여 1.2 mm 두께로 절단하였다. 절단된 시편은 순면을 먼저 편평하게 연마하고,절단된 면을 연마하여 두께 1 mm의 시편을 완성하였다. 완성된 시편(우치 25개)을 무작위로 추출하여 3개의 그룹으로 나누고 나머지는 대조군으로 하였다. Opalescence (10% carbamide peroxide, Ultradent, Milford, USA), Rembrandt (10% carbamide peroxide, DenMat, USA) 및 Opalescence F(15% carbamide peroxide with fluoride, Ultradent)를 시편의 순면에 1주일 동안 적용 (표백제는 24시간마다 교체)하였고, 설측면은 증류수를 적신 거즈에 접촉된 상태로 보관하였다 표백제를 적용하기 전과 적용 3, 5, 7일째에 시편의 삼자극치 X, Y, Z 값을 색채색차계 (Color & Color Differencemeter, Model TC-6FX, Tokyo Denshoku Co., Japan)로 백색 배경판과 흑색 배경판 상에서 측정하였다 백색 배경판과 흑색 배경판 상에서 측정된 Y값의 평균값을 이용해 contrast ratio를 계산하였다 얻어진 값을 One Way Repeated Measured ANOVA를 이용하여 통계 처리한 결과 10% Opalescence처치군, 15% Opalescence-F처치군 및 대조군에서는 통계적으로 유의할만한 증감을 보이지 않았고, Rembrandt처치군에서는 Contrast ratio가 증가하였다 (p < 0.01) . This study was done to evaluate whether vital bleaching agents could influence on the translucency of the bovine enamel. The anterior bovine teeth that were extracted one day before and without any gross discoloration were obtained and then were preserved in physiologic saline. 6 mm cylindrical tooth specimens were fabricated with diamond puncher perpendicularly on labial surface of bovine tooth. After embedded in transparent acrylic resin with labial surface being exposed, they were cut to a thickness of 1.2 mm with low speed diamond saw (Isomat, Buehler Co., Lake Bluff, IL, USA). They were smoothly ground to 1 mm thickness of enamel with sandpaper. 24 specimens were randomly divided into 3 groups and control group respectively. Opalescence (10% carbamide peroxide, Ultradent, South Jordan, USA), Rembrandt (10% carbamide peroxide, DenMat, USA) and Opalescence F (15% carbamide peroxide with fluoride, Ultradent, USA) were applied on labial sides of the bovine enamel for 7 days (bleaching agents were reapplied every 24 hours) and the opposite surface was contacted to cotton that soaked in distilled water. The control group was soaked in distilled water. Three stimulus value X, Y and Z were evaluated with colorimeter (Color ' Color Differencerneter, Model TC-6FX, Tokyo Denshoku Co., Japan) on the labial surface of all specimen three times on white and black background plate before the bleaching agents were applied and on 3rd, 5th and 7th day after applied. The degree of translucency was normally assessed by measuring the inverse property, opacity (contrast ratio). 10% Opalescence, 15% Opalescence-F, and control group showed no significant variation in the translucency of bovine enamel, However Rembrandt decreased the translucency of it (p < 0.01).

Dysfunction of the inferior alveolar nerve indicated by various degree of numbness of the lower lip and chin is one of the few drawbacks of mandibular osteotomy, especially Bilateral Sagittal Split Ramus Osteotomy(BSSRO) and genioplasty. Although it has been recorded throughout the history of this techniques, it is true etiology poorly understood. In this study, 22 consecutive patients under class III malocclusiion impression and undergoing orthognathic surgery(BSSRO only 11 case, BSSRO with genioplasty 11 case) were studied using 4 neurosensory test(static light touch, directional discrimination, two-point discrimination, pin pressure nociception) with post OP 1 week, 2 weeks,4 weeks, 8 weeks, 12 weeks, 24 weeks, On control group, 10 members without trauma and nerve damage history, nerve test was accomplished. We concluded majority of patients return of sensation during post operative 24 weeks. Althought immediate nerve deficit are 92.2%, 97.2% 88.9% these are recovered to 25%, 35.72%, 10.71% at 24 weeks. Nerve recovery rate increased prominently between post 4 weeks and 8 weeks. There is no statistically difference about neurosensory deficit among the chin area. Neurosensory deficit more severe when the BSSRO with genioplasty group than the only BSSRO group. Immediate neurosensory deficit is larger left side than right side but after 6 months, there is no significantly difference between left side and right side. Static light touch and pin pressure nociception are more sensitive method of neurosensory deficit than two point discrimination.
