Bone materials diggd up from the Haemi nameless martyrdom holy place burial sites were severely broken into fragments of various size, clay matrix filled the bone marrow cavities, grass roots were spreaded into the periosteum and the fragments were very soft enough to be flaken. To make permanent specimens, bony fragments impregnated within unsaturated polyester resin with catalyzer MEKP, promotor 8% cobalt octoate, and UV absorber. Permanent specimens were so very transparent that all the macroscopic structures can be observed, and they were hard enough not to be broken or cracked. This method of preserving bony fragments is considered to be used in archaeologic preservation and in making teaching materials of various human organs or tissues.

The "flosting knee" is the term applied to the flail knee joint segment resulting from a fracture of the shaft of adiacent metanhysis of the ipsilateralfemur and tibia. The various methods of treatment of the "floating knee" were adapted by many authors according to degree of the comminution, degree of the soft tissue injury, general condition state of the fracture. Authors experienced the floating knee in 52 cases on 51 patients who were treated at Soon Chun Hyang University Hospital in the period of 4 years and 5 months from January 1985 to June 1989 and among them, 45 cases were treated by operative method and 7 cases by conservative methods at least one of the femur and tibia, The results were as follews;1. Floating Knee occured six times more in male and the peak age was third and fourth decades. 2. The most common cause of fractures was traffie aecident and there was difficulty in diagnosis of ligamentous disruption of the ipsilateral knee. 3. The common fracture site were middle one third and the most common fracture shape was comminuted in both femur and tibia. 4. A good or excellent functional result was aohieved in treated with open reduction and rigid fixation of both fracture and there were no significant difference in group of the internal fixation of both femur and tibia. 5. Intramedullary nailing on the femur and plate fixation on the tibia provided rigid fixation of fracture and the it made possible early joint motion exercise and ambulation and the average healing time of fracuture was much shortened. 6. The most common concomitant injury were soft tissue injury and delayed or nonuion and osteomyelitis were developed more frequently in the plate and screw fixation group of the open fracture.

The majority of fractures of the distal humerus in adults involves the articular surface and also shows the shape of T or Y type and comminuted fracture, this type of fracture is rare in human fractures. The fracture of the distal humerus occurs more frequently in adults than children and has more complications and is more difficult to treat. There are various rnethods of treatments. The Orthopedic Surgery dept of Keimyung Univ. School of medicine has carried out the follow-up studies among 26 cases of inpatients with comminuted fractures, of the distal humerus (who have been admitted to the hospital) from the period beginning Jan, 1978 to May, 1983, and the results are as follows: 1. There were more frequently occured in male (53.8%), and mean age was 43.5 years. 2. There were no bilateral fractures and more common in right side (57.7%) 3. Traffic accidents were the most frequent cause (46.1%), followed by slipping down(38.5%), falls from height, and athletic injuries. 4. The Tyte IIl (50.0%) was most common by Riseborough and Radin classification followed by the order of type IV, type II and type I . 5. In the case of operative treatment, the duration of immobilization took a shorter period than with conservative treatment and the former showed a relatively good prognosis. 6. Better prognosis was obtained by using K-wire fixation, especially in the case of severe comminuted type IV fracture.

The fat embolism is a complication which occurs rarely in cases of long bone of lower extremity and pelvic bone fractures or after severe injury of soft tissue, and may result in an embolism in the lungs, brain, heart, kidneys and other important vessels when fat globules flow from bone marrow into such areas. There has been much adverse criticism about the pathogenesis of fat embolism including the incidence, diagnosis and treatment of it, and studies on this subject have been prevalent in recent years. The following results have been obtained through the study of 9 cases of fat embolism at the Department of Orthopaedic Surgery, Dong San Medical Center, Keimyung University during the period from 1973 to 1984. 1. By sex and age distribution, most of the patients were under the age of 40 and there were more male than female patients. 2. Seven cases were caused by traffic accidents and two were caused by falls accompanied by multiple fractures of the femur and pelvic bone. 3. Symptoms generally occured within 48 houres after trauma, however some cases were within 12 houres, some were 5 days and others 12 days. Clinical symptoms which were present at the time admission revealed increased erythrocyte sedimentation tates and decreased hemoglobin and platelete in most cases. Bilateral infiltrates and cotton ball appearances were found in all cases on thoracic radiology, but no fat globules were found in the urine or in frozen sections of clotted blood. 4. Blood gas analysis was performed in 4 cases and Pa02 under 60mmHg found in all cases increased gradually after treatment. 5. Of the 9 cases with fat embolism 6 cases completely recovered and three cases expired.

BACKGROUND: BRAF mutation has been recognized as an important biomarker of colorectal cancer (CRC) for targeted therapy and prognosis prediction. However, sequencing for every CRC case is not cost-effective. An antibody specific for BRAF V600E mutant protein has been introduced, and we thus examined the utility of BRAF VE1 immunohistochemistry for evaluating BRAF mutations in CRC. METHODS: Fifty-one BRAF-mutated CRCs and 100 age and sexmatched BRAF wild-type CRCs between 2005 and 2015 were selected from the archives of Asan Medical Center. Tissue microarrays were constructed and stained with BRAF VE1 antibody. RESULTS: Forty-nine of the 51 BRAF-mutant CRCs (96.1%) showed more than moderate cytoplasmic staining, except for two weakly stained cases. Six of 100 BRAF wild-type cases also stained positive with BRAF VE1 antibody; four stained weakly and two stained moderately. Normal colonic crypts showed nonspecific weak staining, and a few CRC cases exhibited moderate nuclear reactivity (3 BRAF-mutant and 10 BRAF wild-type cases). BRAF-mutated CRC patients had higher pathologic stages and worse survival than BRAF wild-type patients. CONCLUSIONS: BRAF VE1 immunohistochemistry showed high sensitivity and specificity, but occasional nonspecific staining in tumor cell nuclei and normal colonic crypts may limit their routine clinical use. Thus, BRAF VE1 immunohistochemistry may be a useful screening tool for BRAF V600E mutation in CRCs, provided that additional sequencing studies can be done to confirm the mutation in BRAF VE1 antibody-positive cases.

The aim of this study was to evaluate the appropriateness of some kinds of surgery and admission, such as cesarean section (C/S), cholecystectomy, and pediatric pneumonia. For appropriateness evaluation, we ourselves developed some criteria, which were included in the category of explicit and linear criteria, with the assistance of specialists of relevant clinical field. The evaluation of appropriateness was performed by two family physicians. The major findings were as follows: 1. For ceserean section, 77.6% of deliveries were determined to be 'appropriate', but the level of appropriateness was not significantly different among hospitals between hospital groups by size. The most frequent indication of C/S was repeated operation, followed by cephalopelvic disproportion(CPD). The labor trials for vaginal delivery among repeated C/S and CPD cases were performed in 24.5% of pertinent deliveries. 2. About 73.8% of cholecystectomy cases was appropriate to one of the surgical indications, without significant differences among hospitals. Of surgical indications, 'sufficiently frequent and intense symptom recurrence' was the most frequent, and 'confirmed acute cholecystitis' was the second. 3. Of children admitted due to pneumonia, only 57.4% of cases satisfied admission criteria, and the level of appropriateness of admission was different among hospitals. The common reasons for admission were 'failure to initial treatment', 'suspected bacterial pnermonia', 'young infant', etc. We could find that there were differences of quality among hospitals in some procedures, especially in the pediatric pneumonia and labor trial before C/S, which suggested that the implementation of quality assurance activities would be necessary in this country. In this study, we used some simple and primitive research tools and the numbers of subjects and tracer procedures were limited. So advanced studies with plentiful subjects and more representative diseases or procedures should be tried.

BACKGROUND: Circadian rhythms have been described for many cardiovascular phenomenon, both physiologic and pathologic. However, its frequency of onset in nonsustained ventricular tachycardia(NVT) has rarely been studied. Hence, this study was performed to examine the occurence of circardian rhythm in patients with NVT and to access underlying factors affecting it. METHOD: Among about 2000 patients who had undergone 24-hour Holter recordings between 1988 and August 1992, 46 patients with one or more ventricular tachyardia(VT) episode were selected. In this group, subjects receiving antiarrhythmic drug, including beta blockers were excluded. RESULTS: The frequency of onset of circadian rhythm in NVT peaked between 10 to 11AM and 6 to 7PM. In patiens younger than 60 years, its frequency was highest between 9 AM to 12 noon and 6 to 8 PM, whereas peak occurred around 9 AM in the morning in other age groups. In addition, circadian rhythm was more frequent in female NVT patients between 9 to 11 AM, while peaking between 6 to 8 PM in male patients. Moreover, higher frequency was shown during the day in patients with underlying heart disease, although the peak occurred in 9 AM and 8 PM in patients without any heart disease. CONCLUSION: In NVT patients, the frequency of onset of circadian rhythm varied with time of the day, showing nearly equal peaks in the morning and in the evening. This is similar to rnythms described for acute myocardial infarction and sudden death. Furthmore, the occurrence was affected by age, sex and presence of underlying disease.
