Since Combes' first description of hepatitis B virus associated membranous glomerulonephritis, many reports have shown a strong association of hepatitis B virus infection with various types of nephropathies, especially membranous glomerulonephritis and membranoproliferative glomerulonephritis. Recently, the authors experienced a case of membranoproliferative glomerulonephritis, type I in a 16-year-old male patient with persistent HBs and HBe antigenemia. One year prior to admission the patient was told of hepatitis at routine check, but he remained asymptomatic throughout. He was admitted to our hospital with chief complaints of proteinuria and microscopic hematuria found on routine urinalysis. Liver and kidney biopsy revealed chronic persistent hepatitis and membranoproliferative glomerulonephritis type I, respectively. We report a case of hepatitis B virus associated nephropathy with review of the literatures. Considering the endemic nature of hepatitis B virus infection in Korea, the incidence of hepatitis B virus associated nephropathy would be proportionally high in comparison with those of other countries. So, the importance of this entity merits special consideration in our country. Further study concerning pathogenesis, epidemiology, and treatment may be needed.

PURPOSE: To investigate the localization and functional lateralization of the supplementary motor area (SMA) in motor activation tests in comparison to that of the primary motor area. MATERIALS AND METHODS: Seven healthy volunteers obtained echoplanar imaging blood oxygen level dependent technique. This study was carried on 1.5T Siemens Magneton Vision system with the standard head coil. Parameters of EPI were followed as ; TR/TE; 1.0/66.0 msec. flip angle : 90degree, field of view : 22cmx22cm, matrix : 128x128, slice number/slice thickness/gap : 10/4mm/0.8mm with fat suppression technique. Motor task as finger opposition in each hand consisted of 3 sets of alternative rest and activation periods. Postprocessing were done on Stimulate 5.0 by using cross-correlation statistics. To compare the functional lateralization of the SMA in the right and left hand tests, each examination was evaluation for the percent change of signal intensity and the number of activated voxels both in the SMA and in the primary motor area. Hemispheric asymmetry was defined as difference of summation of the activated yokels between each hemisphere. RESULTS: Percent change of signal intensity in the SMA (2.49-3.06%) is lower than that of primary motor area(4.4-7.23%). Percent change of signal intensity including activated voxels were observed almost equally in the right and left SMA. As for summation of activated voxels primary motor area had significant difference between each hemisphere but not did the SMA. CONCLUSION: Preferred contralateral dominant hemisphere and hemispheric asymmetry were detected in the primary motor area but not in the SMA.

The clinical observation of ureterolithotomy without closure of the ureter was done in 57 patients during the period from Sep., 1970 to Aug., 1974 in the Department of Urology. Daegu Presbyterian Medical Center. The results are as follows. 1) Incidence of ureteral stones is higher in male than in female, ratio M:F=1.6:1 and the most common age group is from 30 to 39 years with 54.3% of the total cases. 2) Locational distribution of ureteral stone; 27 cases in the upper, 5 in the middle and 25 in the lower ureter. 3) The size of ureteral stone is from 0.3 x O.4cm to 1.4x 2.2cm. The average size is 0.48x 0.80cm. 4) The druation of post-operative urine drainage was 7.4 days in the upper ureter, 4.4 days in the mid ureter and 7.6 days in the lower ureter. 5) Post-operative complications: Persistent urine leakage requiring retrograde catheterization; 1 case. Pyelonephritis : 2 cases. 6) Change of post-operative I. V. P. findings; Improved in 50 cases, not changed in 3 cases and deteriorated in 4 cases. 7) Post operative hospital stay; 10. 5 days in the upper, 8.4 days in the mid and 11.3 days in the lower ureter.

In the diagnosis of acute spinal trauma, meticulous physical examination and history taking is the most important tool and auxilliary support support can be given by plain X-ray, CT or myelography, etc. But these cannot show the state of cord injury directly. On the contrary, MRI shows the cord directly as well as the soft and bony tissues. We analysed retrospectively 39 patients who suffered from acute spinal trauma at the level of cervical and thoracic spine and had their spine MRI taken. We verified the meaningful correlation between the signal change in the spinal cord on MRI and the degree of neurologic deficit and prognosis, using Frankel classification and trauma motor index at the time of admission and the final follow-up.

In addition to general charceteristics of tibial fracture, segmental tibial fracture is commonly combined with extensive soft tissue injury, comminution and displacement with poor blood supply in its middle segment. According to recent reports, intramedullary nailing was regarded as the excellent method in the management of this kind of fracture. Twenty-one cases were treated at the department of Orthopaedic Surgery, National Medical Center from January 1980 to December 1987 and following results were obtained; 1. Most common type of fracture was Type I (38.1%). Almost all the fractures were accompanied by open wounds(85.7%) and GIIIB open wounds were 12 cases(57.1%). 2. A verage union time was 31.8 weeks(union rate, 76.2%) and showed marked difference between closed fracture(20.2 weeks) and GIIIB open one(38.6 weeks). 3. Better results were seen in 8 cases of intramedullary nailing(average union time, 24.2 weeks), while all the plating method showed non-union in 3 cases of open wound.
