A case of 14 year-old female with linear porokeratosis is reported with review of articles. She has been suffering from dark brownish, typical porokeratotic patches on the face, neck, right axilla, left hand and left lower extremity. Each lesions are distributed in linear arrangement. Family and past history are not contributory. On histologic examination of skin specimen shows typical cornoid lamella which is hallmark of this disease. Treament was carried with 5go salicylic acid ointment and 0. 025% halcinonide ointment alternatively without successful response.

This study was conducted to invetigate the effect of high-dose steroid administration on adipogenesis and secretion of PAI-1 in rat. Sixty healthy Wistar rats were divided into three groups. Group A consisted of 20 control animals received 5 ml/kg isotonic saline for 1 weeks. Group B consisted of 20 animals received 10 ml/kg of methylprednisolone intraperitoeally for 1 week. Group C comprized 20 animals received 10 ml/kg of methylprednisolone intraperitoneally for 1 week. After the completionof treatment, blood sampling was performed for measurenement of PAI-1 and the animale were sacrificed for histopathologic examination and immunohistochemical study. The PAI-1 protein expressin of femoral heads were evaluated with Western-blotting. Blood level of PAI-1 increased significantly in high-dose steroid treated group(Group B and C) compared to control group. In histopathologic examination, significant fat morrow conversion, fat cell hypertrophy and fat cyst formation were observed in high-dose steroid treated group. Immunohistochemically, PAi-1 expression was sprominent in the fat cells. Protein expression of PAI-1 of femoral heads increased significantly in highdose steroid treated group compared to control group. In lights of above results, it is postulated that increased secretion of PAI-1 from fat cells could play a major role in the pathogenesis of osteonecrosis of the femoral head in rats treated with high-dose steroid.

BACKGROUND: To evaluate the usefulness of exercise echocardiography in diagnosis of coronary artery disease and to compare it with exercise ECG test. METHOD: We performed exercise test in 48 patients who suffered from angina-like chest pain, according to the modified Bruce protocol. During exercise, we observed the ECG changes and recored the images of left ventricular wall motion before and after exercise on the video tape. The echocardiogram were digitally stored and displayed in a format that allowed simultaneous analysis of rest and stress images. Newly developed left ventricular wall motion abnormalities were determined as positive findings. RESULTS: The feasibility of exercise echocardiography was 75%. The sensitivity and specificity fo exercise ECG test was 67% and 89%. The sensitivity and specificity of exercise echocardiography was 85% and 100%. The sensitivity of ECG and echocardiography was 50%(7 of 14) and 78.6%(11 of 14) in those with one-vessle disease and 84.6%(11 of 13) and 92.3%(12 fo 13) in those with multi-vessle disease. CONCLUSION: Exercise stress echocardiography was very usefull method for detecting the coronary artery disease especially in single vessle disease. And it had much higher accuracy than the stress ECG test.

To evaluate the risk factors affecting mortality in blunt abdominal injury we prospectively analysed 149 abdominal traumatic patients, who were performed laparotomy in 84 cases and conservative management in 65 cases, from January 1st. 1995 to September 30th. 1996. The liver was most frequently injured intraabdominal organ(46.3%), followed by spleen(32.9%), kidney(23.5%), small intestine(16.1%) and mesentery(13.4%). Mortality rate was 19.5%. The cause of death was hemorrhagic shock and its complications in 11 cases, craniocerebral injuries in 7 cases, pulmonary complications in 6 cases, and septic shock in 5 cases. The presence of hypotension(less than 90mmHg), head trauma(above 3 in severity code of abbreviated injury scale(AIS)) and chest trauma(hemothorax and/or pneumothorax) was associated with a high mortality rate(88.9%), but the mortality rate for the patients neither hypotension nor head and chest trauma was very low(1.8%). The mortality in the blunt abdominal injuries was highly influenced by hypotension, head injury and multiple intraabdominal injuries(p<0.05). Of the above influencing risk factors, the associated head injury was the most powerful determinant in the prognosis in the patients of blunt abdominal injuries.

We studied the contents of referral sheets of the patients transferred to DMC Emergency Center from Jan 1, 1999 to Jan 31, 1999. The study far the completion and chief complaints in the referral sheets shows the followings. 1. Examining the referral sheets status of disease, name and age record of 5 major items grade 0.92, the highest point, examining item and laboratorial record grade 0.72, dignosis record grades 0.38, and patients condition and diagnosis opinion record grade 0.10. 2, Name and age item had high completion score in referral sheets from local clinic and hospital for secondary referral level. For address item, however, local clinic scored 0.63 and hospital for secondary referral level scored 0.28, which showed statistically significant difference(P<0.001). 3. In the aspect of severity, name and age record leveled 0.94 to the non emergency patient, 0.92 to the emergency patient, 0.91 urgent patient, showed and no statistic significant difference. 4. The major 10 symptoms of the complaints were these the pain of abdomen and pelvis(25.2%), somnolence and stupor, coma(13.6%), headache(10.9%), and open wound of head(4.0%), ranked 10th common symptom level.
