We have encountered many patients with dermatologic problems caused by animals, but there are not so many systematized literature about them in Korea. Since these causative animals are different from foreign animals in their distribution and habitat, there have been much difficulties in making diagnosis and in studying them based on foreign literature. We have undertaken this study to get the basic material for the possible causative animals in Korea by comparing with foreign literature, searching out the books of zoological claasification, and through personal contacts. One hundred and five species are found to be identical with the species reported in foreign literature, but 324 species are not, although they could be placed in the same genus.

Neuroleptic malignant syndrome is a rare, but potentially life-threatening adverse event associated with the use of neuroleptic agents. We describe the case of a 47-year-old schizophrenic woman who was treated with clozapine for years. The patient developed acute renal failure with pulmonary edema, and underwent mechanical ventilation and hemodialysis.

This paper describes a case of intrapericardial teratoma in a 20-day-old female meonate, who suffered from cyanosis and respiratory difficulty. She was evaluated by echocardiography, chest CT and MRI, the suspected cyanosis and respiratory difficulty. She was evaluated by echocardiography, chest CT and MRI, the suspected intrapericardial mass was identified and surgically removed. The postopervative diagnosis was intrapericardial teratoma, grade II. This case is reported with brief review of some related literature.

PURPOSE: Extrapleural fat hypertrophy is thought to be associated with findings of chronic pleural or pulmonary parenchymal diseases, and more favours clinical course of benign disease rather than malignant disease which is rapidly progressive. Recently, however, we observed frequent extrapleural fat hypertrophy in CT scens of lung cencer patients, especially those with complicated ones. We studied the frequency of extrapleural fat hypertrophy and the relationship between the extrapleural fat hypertrophy and the complications of lung cancer. MATERIALS AND METHODS: We retrospectively analized the CT findings in 95 patients with primary lung cancer. 85 patients were confirmed pathologically and 10 patients were confirmed by clinical and radiological follow-up studies. RESULTS: Among the 95 patients, 79 patients were associated with more than one complications(Lung collapse, pneumonia, pulmonary tuberculosis., pleural reaction, pleural metastasis, empyema, chest wall invasion). Extrapleural fat hypertrophy was observed in 43(54%) patients with complication, and 2(13% ) patients without complication. The frequency of the extrapleural fat hypertrophy was 40%(14/35) in patients with only parenchymal complicated patients, 33%(2/6) in patients with only pleural complication, and 71%(27/38) in patients with both parenchymal and pleural complications. CONCLUSION: Extrapleural fat hypertrophy was more frequently observed in complicated lung cancer patients rather than non-complicated, and higher frequency of the extrapleural fat hypertrophy was noted in those with more than two complications. It was concluded that extrapleural fat hypertrophy in lung cancer patients was non-specific finding caused by associated complication. Its mechanism is thought to be chronic pleural irritation and negative thoracic pressure.

The tests for sputum acid fast bacilli and sputum cytology for malignancy were negative. The PC20 of bronchial methacholine challenge test was 20.2 mg/ml. Transbronchial lung biopsy showed bronchial inflammatory change with infiltration of eosinophils and the existence of fungal hypae. Antibody index for serum IgE-Af and IgG-Af was 10.2 and 2.1 respectively, comparing with Af-sensitive asthma patients. Recently we experienced an allergic bron-chopulmonary aspergillosis with atypical respiratory symptoms. Forty-seven years old female was admitted to our hospital because of cough, sputum, right pleuritic pain for 2 weeks. She had experienced pneumonia several times, but had been not confirmed any causative organism. On physical examination, breathing sound was decreased over right upper lung, but wheezing and crackle were not heard over both lungs. The chest X-ray showed segmental consolidation in right upper lobe, and HRCT showed tubular bronchiectasis and obstruction of right upper lobal bronchus due to mucoid impaction. Allergic skin prick test against Aspergillus fumigatus(Af) and serum preeipitin were negative, but intrader mal skin test was positive for Af. Specific IgE for Af was positive with class I. Total eosinophil count was 650/mm3, total IgE level was more than 3000 IU/ml, ESR was 62mm/hr, and eosinophils in induced sputum was 35%. The test for sputum acid fast bacilli and spu-Tum cytology for malignancy were negative. The PC20 of bronchial methacholine challenge-Test was 20.2 mg/ml.

PURPOSE: To evaluate CT findings for the differential diagnosis of mechanical bowel obstruction and paralytic ileus. MATERIALS AND METHODS: Without information relating to clinical or operative findings, we retrospectively analyzed the CT scans of 24 patients with mechanical bowel obstruction and 19 patients with paralytic ileus. Final diagnosis was confirmed by operation (n=26), or by clinical symptoms, radiologic findings and follow-up study CT findings were obtained : 1) the diameter of the most dilated part of the small bowel, and the thickness and enhancing pattern of the dilated small bowel wall; 2) the diameter of the most dilated part of the descending colon and the ratio of the diameter of the small bowel to that of the descending colon; 3) the number of transitional zones, length and thickness. and 4) associated ascites and its location. RESULTS: The mean diameters of the most dilated part of the small bowel in mechanical bowel obstruction and paralytic ileus were 3.6cm and 2.9cm, respectively. The diameter of the small bowel in mechanical bowel obstruction was significantly greater than in paralytic ileus(p< .05). The mean thickness of dilated small bowel wall was 4.0mm in mechanical bowel obstruction and 2.4mm in paralytic ielus, and target-like enhancement was prominent in mechanical bowel obstruction (46%) (p< .05). he mean diameter of the most dilated part of the descending colon was not significantly different to that of the most dilated part of the small bowel, but the ratio of the diameter of the small bowel to that of the colon was 2.9 in mechanical bowel obstruction and 1.9 in paralytic ileus, respectively, which was statistically significant (p< .05). A transitional zone was seen in 23 cases (96%) of mechanical bowel obstruction and in nine (47%) of paralytic ileus. In mechanical bowel obstruction, mean transitional zone length was 2cm, shorter than that of paralytic ileus (3.4cm) (p< .05) The thickness of transitional zone and the presence of ascites and its locations were not significantly different between mechanical bowel obstrction and paralytic ileus. CONCLUSION: In the differential diagnosis of mechanical bowel obstruction and paralytic ileus, the following CT findings were considered useful : diameter of the most dilated part of the small bowel ; thickness and target-like enhancing pattern of dilated small bowel wall ; ratio of the diameter of the small bowel to that of the descending colon ; and the number of transitional zones, and their length.

BACKGROUND/AIMS: We examined the ischemia-modified albumin (IMA) level during exercise in patients with coronary artery disease (CAD). METHODS: Forty patients with a history of chest pain underwent both symptom-limited treadmill exercise stress testing and coronary angiography within one week. During the treadmill tests, blood samples were obtained at baseline and 5 min after exercise to measure the serum IMA level. RESULTS: Of the 40 patients, fourteen (35%, CAD group) had significant coronary artery stenosis, while the other 26 (65%, non-CAD group) did not. The baseline and post-exercise IMA levels in the two groups did not differ significantly (105.2+/-7.2 vs. 107.7+/-6.7 U/mL at baseline and 93.1+/-10.1 vs. 94.8+/-5.7 U/mL at post-exercise in the CAD and non-CAD groups, p=0.29 and 0.57, respectively). The changes in IMA after exercise did not differ either (-10.4+/-7.5 vs. -14.0+/-7.6 U/mL in the CAD and non-CAD groups, respectively, p=0.10). Similarly, the change in IMA between the exercise ECG test positive (TMT positive, n=9) and negative (TMT negative, n=20) groups did not differ (-14.63+/-5.19, vs -8.50+/-9.01 U/mL, p=0.15, in the TMT positive and negative groups, respectively). CONCLUSIONS: Our results suggest that IMA has limitation in detecting myocardial ischemia during symptom-limited exercise stress tests.

PURPOSE: To evaluate the effect of respiration on the sizes of intrathoracic vasculature, and the trachea,and the main bronchus. MATERIALS AND METHODS: Seventeen volunteers (10males aged 20-39 years and 7 females aged20-39 years) underwent spiral CT, between the apex and lowest base of the lung, collimation was 10mm, pitch was 1,and images were obtained at breath hold forced end-inspiration and breath hold forced end-expiration. Crosssecional areas or diameters were measured in each respiration state at the aorta (ascending, descending, lowerthoracic) and great branches, the IVC (thoracic, abdominal), the SVC, pulmonary artery (right main, leftdescending) and the tracheobronchus (trachea, left upper bronchus). Changes in the size of vessels and airwaysbetween the respiration states were evaluated and compared between inspiration and expiration. RESULT: Duringbreath-hold forced end-inspiration CT, the ascending, descending, and lower thoracic aorta and itsbranches(brachiocephalic, left common carotid, left subclavian) as well as the thoracic IVC and SVC and the rightmain and left descending pulmonary arteries decreased in size: during breath-hold forced end-expiration CT, thesize of all these vessels increased. For the trachea, left upper lobe bronchus and abdominal IVC, the situationwas reversed. Statistically significant changes(p<0.05) were noted in the ascending aorta and descending aorta,the lower thoracic aorta, the thoracic and abdominal IVC, the SVC, the right main and left pulmonary arteries, andthe trachea. CONCLUSION: During respiration, changes in the size of the thoracic vasculature and airways isprobably due to changes in intrathoracic pressure. In the measurement and diagnosis of stenosis or dilatation inthe intrathoracic vesculature and airways, respiration states should therefore be considered.

Recently there has been renewed interest in the use of highly concentrated saline solutions and colloidal fluid to resuscitate animals and humans from hypovolemic shock. In this study, effects of resuscitation with various fluids were compared in a cat model of acute hemorrhage. After anesthesia, the cat was exanguinated from the femoral artery, and an equivalent amount of fluid was injected through the femoral vein. Therefore this study was performed to evaluate the effects of gelatin in comparison with others. The results were as follows 1) Compared to crystalloid solution, colloidal soluions were more effective in restoring hemodynamic disturbance but there were no significant differences between Gelatin and Dextran group at same dosage level. 2) Mean arterial pressure was significantly increased in dextran and gelatin group after 30 minutes of fluid resuscitation(p<0.05). 3) Decreased hemoglobin due to plasma volume expansion was noticed in all group's(p<0.05) 4) After replacement of dextran and gelatin, central venous pressure was restored effectively(p < 0.05). 5) Decreased ETCO was recovered after replacement of fluid, but no difference among three groups. 6) Increased potassium level was redecreased 30 minutes after replacement of gelatin(p < 0.05). 7) Sodium level was decreased after hemorrhange in all three groups and after replacement of H/D and dextran, but no change in gelatin group(p<0.05). 8) Increased lactate after hemorrhage was decreased in gelatin and dextran group. 8) Decreased pH restored after replacement of dextran and gelatin.
