The posterior cruciate ligament(PCL) is one of the most important structures in the knee joing because it provides about 94% of the total restraint to posterior displacement of the tibia & posterior stability of the knee joint. If the posterior instability persisted, rotational instability, injury to meniscus and degenerative change develop within several years. The purpose of this study is to know the result of the posterior cruciate ligament reconstruction using semitendinosus tendon and to know the factors which affected to good result. During the period from January 1989 to December 1994, 16 cases with posterior cruciate ligament reconstruction using semitendinosus tendon were evaluated clinical and radiological results retrospectively and performed stastical analysis using the SPSS. The results were as follows; 1. The average preoperative posterior laxity was 14.1 mm and average postoperative laxity was 6.3 mm. It was improved 7.8 mm. 2. In other associated injured ligament group with or without fracture, above good was in 8 cases and below fair in 6 cases, but there was no significant difference between the two (X²=9.8, df=1, P>0.05). 3. In the poor result group, mean body weight was 80(±13.23)kg and there was significant difference between poor group & fair, good, excellent group(F=3.52, P < 0.05). From these results it would be suggested that PCL reconstruction using semitendinosus tendon is more effective in relatively light weighted group than heavier group.

Magnetic resonance (MR) is rapidly emerging technique that provides high quality images and potentially provides much more diagnostic information than do conventional imaging modalities. MRI is conceptually quite different from currently used imaging methods. The complex nature of MRI allows a great deal of flexibility in image production and available information, and key points are as follows. 1. MR offers a non-invasive technique with which to generate in vivo human images without ionizing radiation and with no known adverse biological effects. 2. Imaging mechanism of MRI is quite different from conventional imaging modality and for more accurate diagnostic application, It is necessary for physician to understand imaging mechanism of MRI 3. M.R. makes available basic chemical parameters that may provide to be useful for diagnostic medical imaging and more specific pathophysiologic information which are not available by alternate techniques. 4. M.R. can be produced by number of different methods. This flexibility allows the imaging technique to be applicated for particular clinical purpose. Multiplanar and three dimensional imaging may extend the imaging process beyond the single section available with current CT. 5. Future directions include efforts to; a. Further development of hard ware b. More fastening scan time c. Respiratory and cardiac gated imaging d. Imaging of additional nuclei except hydrogen. e. Further development of contrast media f. MR in vivo spectroscopy g. Real time MR imaging

Computerized Tomography is now well established and important noninvasive method of diagnosting mediastinal mass lesions because of its superior imaging of their size, location and internal composition. Authors analyzed and present CT findings of 30 surgically proven mediastinal tumors and cysts that were studied and treated at the Yeungnam University Hospital during recent 6 years. The most common tumor was thymoma (9 cases), and teratoma (6 cases), lymphoma (6 cases), bronchogenic cyst (4 cases), neurogenic tumor (4 cases), pericardial cyst (1 case) were next in order of frequency. There were 5 cases of thymoma showing homogenous solid density mass, 2 cases were malignant thymoma and myasthenia gravis was present in 2 cases. A case of thymolipoma and a case of thymic carcinoma were included. All teratomas were cystic masses but pathognomonic fat, and calcified density were seen only in 4 cases. 5 cases were located in anterior mediastinum and 1 case was in posterior mediastinum. Lymphoma (3 Hodgkin's and 3 non-Hodgkin's) appeared as irregular lobulated mass in anterior mediastinum. Neurogenic tumor (2 ganglioneuroma and 2 neurilemmoma) appeared as homogenous density mass located in posterior mediastinum. Among the 4 bronchogenic cysts, 2 were located in retrotracheal area, 1 was located in subcarinal and 1 was in parathoracic area. One case of pericardial cyst was oval shaped cystic mass located in left pericardiac border.

Thirty-nine patients with fixed drug eruption who visited the Department of Dermatology in National Medical Center from January 1g7g to December 1982 were selected. Among them, twentyseven patients performed skin biopsy and were evaluated histopathologically on the basis of duration. The results were as follows; ].In the early stage less than 1 week of duration, hydropic degeneration of basal cells, necrotic keratinocytes with eosinophilic cytoplasm and pknotic nucleus in the epidermis, and mixed cell infiltration with eosinophlis in the upper dermis were prominently. In the late stage more than 20 days of duration, acanthosis, an increased amount of melanin in the basal cell layer and presence of melanophages were found more prominent, however, hydropic degeneration of basal cells, papillary dermal ederna, inflammatory infiltration of mononuclear cells were found less prounced or absent.

We report a case of acrodermatitis enteropathica-like syndrome after long-term parenteral nutrition in a 19-year-old female with a choriocarcinoma metastasized to the lung. Skin lesions consisted of vesicopustular periorificial eruptions, psoriasiform plaques on the knees and elbows, eczamatoid patches on the acral regions, paronychia, alopecia, and of poor wound healing, Severe diarrhea was accompanied. Zinc sulphate was administered 200mg three times daily for one week with improvement of the skin eruptions and diarrhea. The patient, however, died on the 7th day of zinc therapy with the poor general condition.

A 68-year-old male patient who was diagnosed as cutaneous mycosis fungoides with plaques, nodules and tumor has been treated with photochemotherapy. Oral methoxsalen followed by ultraviolet light(PUVA) resulted in clinical and histopathologic improvement of skin lesions. Photochemotherapy units consists of boxes with 12 UVA lamps. The initial dose was 8. 4 joules/cm2. The maintenance dose was 10. 5 joules/cm2. The total dose at present time is 1203. 82 joules/cm2. We prppose that PUVA therapy may be a valuable therapeutic regimen for mycosis fungoides.

BACKGROUND: Pathergy, or skin hypersensitivity to needle puncture has been reported as a diagnostic test for Behcets ciisease. But the positivity of pathergy test in recurrent aphthous stomatitis which can be a comporent of Behcets disease is obscure. In recent years it has been noted that the positivity of the test has decreased. It is possible to say that the disposable needles used nowadays are less trauniatic to initiate the reaction than are the nondisposable ones used in the preAIDS ara by some uthors. OBJECTIVE: It is the porpose of this study to clarify the value of pathergy test in differentiating Behcets disease from recurrent aphthous stomatitis and to evaluate the difference of positivity using various kinds of needles, and finally to suggest the most profitable one. METHODS: 34 patients with Behcets disease according to the diagnostic criteria of Shimizu(revisecl) 25 ones in case of applying that of International study group for Behcets disease(ISG) and 21 ones with recurrent aphthous stomatitis, and 25 normal controls were selected. A pathergy test, i.e., intradermal injection of 0.1 ml physiological saline by using 26 gauge & 20 gauge disposable needles and 26 gauge & 20 gauge nondisposable ones were given and the evaluation was made after 24 hours and 48 hours. RESULTS: 1. The positive rates of pathergy test using all kinds of needles in Behcets disease were significantly higher than thoen recurrent aphthous stomatitis and normal controls(p=0.00000-0.03600). The sensitivity were 29.4% 64.7% (Shimizu) and 32.0% 76.0% (ISG), respectively, and the specificity were 91.3%-100.0% for all of them. 2. In Behcets disease, the positive rates of the pathergy test using 26 gauge disposable needles were not significantly different from that of using ZO gauge disposable needles in total and active patients after 24 and 4.3 hours and so were 26 gauge R 20 gauge nondisposable ones(p=0.40134 -0.80603(Shimizu), 0.37551-0.77078(ISG) ). 3. In Behcets disease, the positive rates of pathergy test using 26 gauge nondisposable needles were 59%-68%(Shimiu) and 64% 79% (ISG), which were significantly different, from the test using 20 gauge disposable needles, i.e. 29%-36%(Shimizu), 40%-46%(ISG) in total and active patients(p==0.00753-0.01512) after 24 and 48 hours except for those by the criteria of ISG after 24 hours(p=0.14573-0.15597). CONCLUSION: This study shows that the pathergy test is obviously useful in differentiating Behcets disease from ecurrent aphthous stomatitis and we recommend the intradermal injection of 0.1 ml physiological saline by using 26 gauge nondisposable needle and the evaluation after 48 hours as a standard mithod of pathergy test.

Congenital origin intestinal obstruction are important disease due to required emergency operation. So accurate and rapid diagnosis needed for decreased mortality and morbidity. Radiologic must defect to accurate obstruction site and also associated other congenital anomalies. And also embryological basis are very important role to the diagnosis of these diseases. We were analyzed radiologically and clinically 25 cases with congenital origin intestinal obstruction with review of literature. 1. Hypertrophic pyloric stenosis 6 cases, midgut malrotation 4 cases, congenital megacolon 8 cases, imperforated anus 5 cases, ileal atresia 1 case and duodenal atresia 1 case. 2. Male and female radio was 16:9. Especially on hypertrophic pyloric stenosis, 5 cases were male infants. 3. All cases of hypertrophic pyloric stenosis represented string sign and also pyloric beak sign, shoulder sign on UGI. 4. 1 case duodenal atresia showed double bubble sign on simple abdomen x-ray and ileal atresia showed mechanical small bowel obstruction sign with microcolon. 5. On midgut malrotaton, cecum was located in right upper abdomen on 4 cases. And 2 cases were associated with Ladd's band, 1 case with volvulus and 1 case with mesenteric defect. 6. Involved site of all congenital megacolon were localized to rectosigmoid colon. 7. On 5 cases imperforated anus, 3 cases were low type and 2 case high type. Rectoperitoneal and rectourogenital fistula were demonstrated on 4 cases.
