In order to evaluate the ability of spin-echo MR imaging to differentiate slow flow from mural thrombus in aortic diseases, we reviewed the spin-echo MR images of 13 patients with intraaortic thrombus documented by CT (N=11) or aortography (N=2). Six patients had aortic aneurysms and seven had aortic dissection. Intraaortic mural thrombi were accompanied by flow-related intraluminal signal of various patterns and extents in all 13 patients. On 10 gated MR studies, slow flow regions showed even-echo rephasing phenomenon (N=8), interslice variation of signal intensities of the intraluminal signal (N=7) and flow-related ghost artifact (N=2). However, these MR flow phenomena were obscured on two of three non-gated studies. Seven of 13 intraaortic thrombi remained hyperintense on T2-weighted second-echo images. In these circumstances, a hypointense boundary layer between slow flow and mural thrombus, which was caused by either 'boundary layer dephasing phenomenon' of slow flow or 'paramagnetic T2 shortening' of fresh clot at the edge of mural thrombus, was useful in discriminating the area of slow flow from that of mural thrombus. Proper interpretation of spin-echo MR images may obviate the need for phase display imaging or gradientecho imaging in differentiating slow flow and mural thrombus.

We experienced the 17 hands of 11 patients with Dupuytren disease, which was known as relatively rare in orientals. Retrospectively, we analyse it and the results were followings; l. Among 11 patients, 10 patients were male and average age was 62.5 years (49 to 77 years) 2. Most (15 hands, 88%) of patients had symptoms of flexion contracture, nodule and contracted cord, simultaneously. 3. Occupation of patients was agricultural laborer in 9 patients (82%). 4. In 9 patients(82%); individual habit of alcoholic drinking, more than 3 times per week, and smoking, 1 package per day, over 20 years more, was observed. 5. In 15 hands (88%), ulnar side of fingers (4th+5th, 5th only or 3rd+4th+5th)was involved. 6. Surgical treatment was performed in 9 hands of 7 patients, with results of excellent in 6 hands (67%) and no recurrence, in average follow up 2.6 years (1.5 year to 3.7 year)

Respiratory syncytial virus (RSV) and Influenza virus are the most common pathogen for causing severe upper respiratory infection in all age groups. A multiplex reverse transcription polymerase chain reaction (RT-PCR) has been developed to detect and subtype influenza A (H3N2 and H1N1), B virus and RSV simultaneously in one tube reaction. Amplification with primers derived from conserved sequences within the nucleocapsid for RSV and hemagglutinin subunit for Influenza A (H3N2 and H1N1) and B viruses yielded a 384 bp, a 300 bp, a 236 bp and a 151 bp, respectively. Assay specificity was confirmed by pulse field gel electrophoresis and autosequencing method. Assay sensitivity was 3 PFU/ml of RSV, 22 PFU/ml, 45 PFU/ml of Influenza type A (H3N2 and H1N1) and 6.6 PFU/ml of Influenza B virus by plaque assay. A rapid and sensitive detection method of a one-tube with multiplex RT-PCR capable of identifying more than one viral template as well as synchronizing reverse transcription and PCR had the potential to produce considerable savings of time and cost effectiveness in the diagnostic laboratory.

The aim of the present work is to evaluate the most accurate technique for analysirig low levels of serum IgE. Following results are obtained from experiments by PRIST, Overnight PRIST, PRIST using RAST anti-IgE tracer and Overnight PRIST using RAST anti-IgE tracer methods with cord serum and maternal serum of 21 individuals respectively. 1) There was no statistical significance in maternal serum IgE titer using above 4 methods. However, the higher level of IgE titer was found in PRIST method when IgE was over 190 IU/ml(5 cases) estimated by PRIST method and in Overnight PRIST using RAST anti-IgE tracer method when Ig.E was below lgp IU/ml (16 cases) (p40.05). 2) In cord serum IgE titer, only Overnight PRIST using RAST anti-IgE tracer method showed statistical significance. 3) The most desirable correlation coefficient between maternal serum and cord serum IgE titer was estimated by Overnight PRIST using RAST anti-IgE tracer method than any other rnethods.

Thymic cyst is relatively rare tumor which usually occurs in the neck or mediastinum. Cervical thymic cyst is usually situated laterally and deep to the anterior border of the sternocleidomastoid muscle, simulating a branchial cyst. Thymic cyst of the mediastinum is usually detected incidentally and differential diagnoses include cystic degeneration of thymoma, and cystic teratoma. Two case of a cervical and a mediastinal thymic cysts were reported. The one was a cervical thymic cyst developed slowly growing mass in a 53-year-old male a for 10 years. The cyst was unilocular and measures 5.4x2.9x2.8 cm with columnar or squamous cell linings. The other is a mediastinal thymic cyst developed in a 37-year-old female with chest discomfort for 7 months. The cyst was uniocular and measures 2.8x2.2x2.0 cm. The epithelial lining of the cyst was largely desquamated and covered by macrophages with cholesterol granuloma. Involutional thymic stissue in their walls were noted in both cysts. In both cases presence of thymic tissue in the wall of the cyst thought to be the most important diagnostic feature.
