PURPOSE: For the production and evaluation of the tissue-equivalent phantom. MATERIALS AND METHODS: We used agarous gel and oil as a basic component of the mixture and added Tween 80 for the stabilization of phantoms. We did the test for homogeneity and measured T1 and T2 relexation times of each phantom tube. RESULTS: T1 relaxation time ranged from 642 to 2781 msec and T2 relaxation times from 42 to 157 msec. Each phantom was significantly different in T1 relaxation time and T2 relaxation time (p < .0001). CONCLUSION: Tissue equivalent phantom may provide good information on the optimal sequence before MR imaging of patients and may be valuable if it is used with the patients' MR imaging.

PURPOSE: To evaluate the utility of ultrasonograpy(US) as a guide in deciding drainage methods and as a prognostic factor in the prediction of pleural fibrosis, and to compare the effects of drainage methods in patients with tuberculous pleural effusions. MATERIALS AND METHODS: In 51 patients with tuberculous pleural effusion, US patterns of pleural effusion were classified according to degree of septa into three groups, into three groups, as follows: anechoic (n=5), linear septa (n=15), and honeycombing septa (n=31). US-guided drainage methods, including thoracentesis (n=17), percutaneous catheter insertion (n=12), catheter insertion with urokinase instillation (n=22) were employed. Therapeutic effects were evaluated with follow-up chest radiographs after 3 and 6 months. RESULTS: Three months after the procedure, 43 of 51 effusions had drained effectively. US guided drainage failed in eight patients including two of six with linear septated effusion treated with thoracentesis, four of seven with honeycomb septated effusion treated with thoracentesis, and two of six with honeycombing septated effusion treated with catheter drainage. There was no drainage failure in patients with anechoic effusions and in patients with urokinase instillation. Late effects were assessed in 39 patients after 6 months. Follow-up radiographs available in 39 patients demonstrated pleural fibrosis with intercostal space narrowing in 7 patients with honeycomb septated effusion, 3 patients with linear septated effusion, and none of the patients with anechoic effusions. CONCLUSION: The pattern of septa seen on US could be a useful factor for determining drainage methods and predicting late results in tuberculous pleural effusion. Percutaneous catheter drainage with urokinase instillation was a good drainage modality for patients with septated pleural effusions. Pleural fibrosis is more frequently induced by septated pleural effusion than by anechoic pleural effusion.

Pheochromocytoma remains one of the great challenges to anesthesiologists during anesthesia and postoperative period. Virtually all anesthetic agents and techniques have been used with success but associated with a high rate of transient intraoperative arrhythmia and hypertension. We now report one case who was given thoracic epidural block and neuroleptic anesthesia for resection of right adrenal and presacral pheochromocytoma. Blood pressure and heart rate were stable during induction, tumor manipulation and postoperative intensive care unit with out the use of vasodilating or antiarrhythmic druas. While this report describes only one encouraging case, the potential advantages of thoracic epidural & general anesthesia in pheochromocytoma appear to warrant the further trial.

PURPOSE: The instruction of cardiopulmonary resuscitation (CPR) to students has been advocated in many countries. To formulate an effective policy for high school students in Korea, data on attitudes toward CPR and the levels of knowledge in this technique for this population are needed. METHODS: A thirty-question questionnaire was given to Korean high school juniors to assess their attitudes toward and knowledge level of CPR. Two hundred seventy one of 341 students (79.5%) responded to the questionnaire and their male to female ratio was 1:2.2. RESULTS: Most students (n=262, 96.7%) had heard of CPR, mainly through television (n=193, 71.2%) or a school activity (160, 59.0%). Only 50(18.5%) and 15(5.5%) students responded that they would be willing to provide CPR to a "family or friend" and "stranger", respectively. One hundred twunty four students (45.8%) had received some form of education on CPR, but only 10(3.7%) had received an advanced education (although most were willing to be educated further on CPR). The most common reason for not receiving CPR training was a lack of knowledge for training resources (n=79, 53.7%). Only 88(32.4%) students understood the purpose of an automated external defibrillator. Although half of the students (147, 54.2%) correctly chose the location for CPR chest compression, only 19.2% and 16.6% correctly responded to questions on the appropriate compression speed and depth, respectively. CONCLUSION: Although students receive some exposure on the importance of CPR, their willingness to perform CPR and their knowledge level of AEDs and CPR is not adequate. A systemic approach for educating and training students in CPR is needed.
