In recent years, the rate of the spine fracture tends to be on the increase year by year as rate of traffic and industrial accidents are increased. 111 patients with paralysis caused by thoracic, thoracolumbar, lumbar spine injuries were evaluated from January, 1979 to December, 1988 in our study. 1. In patients with paralysis caused by thoracic, thoracolumbar, lumbar spine injuries, most common site of injuries was “thoracolumbar junction” (47.7%) and most common cause was “fall down” (48.7% ). 2. “Burst fracture” was most common type of injuries which were classified by 3-column concept according to Denis & McAfee(52.3%) 3. In early 1980's the operation was performed with Harrington rod, anterior decompression & AIF, posterior decompression & PIF and from 1984, mainly Luque sublaminar wiring, and in 1988, SSI was commonly used. 4. There was no difference in neural recovery between conservative and operative treatments. 5. There was statistic significance in the incidence of complications between conservative and operative treatments(p <0.05). 6. The more severe neurologic damage at injury, the higher incidence in complication(p<0.05). Therefore, although there was no significant difference in neural recovery between conservative and operative treatments in the care of paralysed patients caused by thoracic, thoracolumbar, lumbar spine injuries, rigid internal fixation and rapid mobilization can be recommended for decreasing complications by prologed bed rest and active rehabilitation.

To investigate the properties and mechanism of PAF and TNF on the synthesis of prostaglandin E2 in human amnion, primary monolayer culture method was used for human amnion cell incubation. Amnion cells were incubated with various concentrations of PAF or TNF in Ca++ containing medium for various duration. Then PG E2 concentrations were measured by RIA and analyzed for the effect of PAF and TNF on PG E2 production according to their doses and incubation time. To test the role of Ca++ in E2 production, Ca++ free medium, Ca++ -channel antagonist and cyclo-oxygenase inhibitor were substituted or added in incubation medium. Following results were obtained. The synthesis of PG E2 was significantly enhanced by PAF of 10(-6) mol/L. The TNF also stimulated PG E2 synthesis at concentration of 10(-6)g/ml. The maximal level in PAF(10-6mol/L)-stimulated release of PG E2 was observed after 16 hours in incubation. The TNF(10(-6)g/ml)-induced PG E2 release was maximal after 24 hours of incubation. Combined application of PAF and TNF produced positive effect in PG E2 production. PAF or TNF stimulated-PG E2 production in Ca++ -free media was much lower than that of Ca++ -containing media. The PAF-stimulated PG E2 release was significantly inhibited by Ca++ -channel antagonist but TNF-stimulated PG E2 release was not effected by Ca++ -channel antagonist or cyclo-oxygenase inhibitor. It is strongly suggested us that both PAF and TNF enhance PG E2 release by amnion cell, although Ca++ -channel opening is essential only for PAF stimulation.

Twenty-three isolates of Fusarium spp. were obtained from decayed citrus fruits in the fields and storages in 1998-1999. Of them, six and five isolates belonged to F. proliferatum and F. moniliforme, respectively, which were the most common. F. solani and F. sambucinum had each two isolates, F. equiseti had one isolate and seven isolates were unidentified. They produced symptoms of two types in pathogenicity test: those with leathery, beige to light or dark brown, and sunken lesions without surface mycelium (type-1) and those with lesions covered with white, beige or pink surface mycelium (type-2). Four of six isolates identified to F. proliferatum and two unidentified isolates produced type-1 lesions, and all isolates identified to F. moniliforme, F. solani, F. sambucinum, F. equiseti and five unidentified isolates produced type-2 lesions.

OBJECTS: Thls study was designed to assess muscle tensions while working at a YDT workstation with surface electromyography (SEMG). METHODS: Variables texted were desk height, monitor positon on the desk, distance from edge of the desk to the keyboard. Eleven female volunteers working in the tele-com munication company were seated at an ergonomically adjusted workstation. They were assigned to a task of typing for 5 minutes and were given a 10 minutes resting with hands in their lap. For the initial experiment, the desk height was fixed to standard desk height(65.0 cm) recommended by ANSI and latter adjusted to a higher desk height (72.8 cm) for this study such that the subjects experienced slight elevation of shoulders. The monitor position initially at the center on the desk and latter left site of the desk (45o from monitorneck axles). The keyboard was positioned to an optimal distance (15 cm from the desk edge) and an abnormal distance (30 cm). Five muscle groups (paraspinal muscles, upper trapezium muscle, supraspinatus muscle, infraspinatus muscle, and rhomboid muscle) were selected for the study. The data of SEMG were analyzed by 2x2x2xs mixed factorial design. RESULTS: The results were as follows: 1. SEMG activity recorded from the paraspinal muscles were significantly higher when the angle of the monitor adjusted to 45 degree from the center of the desk.. 2. SEMG activity recorded from the upper trapezius/supraspinatus/infraspinatus muscles were significantly higher when the hight of the desk was elevated from the recommended height.3. SEMG activity from the rhomboid muscle showed no significantiy difference in all test conditions. CONCLUSIONS: The results of thls study confirm that the helght of a VDT workstation and the angle of the monitor are risk factors of upper extremity cumulative trauma disorders. Also SEMG would be useful for measuring muscle activities during workstation assessment.

We herein present a case of simultaneous occurrence of apocrine adenocarcinoma, syringocystadenoma papilliferum, syringoma, and eccrine hydrocystoma arising in an organoid nevus (nevus sebaceus of Jadassohn) which had been present on the right occipitoparietal scalp of a 60-year-old man since birth.
