A spontaneous spinal epidural hematoma (SSEH) of the thoracic spine is a rare space-occupying disease that accompanied with severe axial pain in the spine. Because there is the possibility of a significant neurological injury such as paraplegia, SSEH requires careful diagnosis and management. A SSEH is mainly caused by a coagulating disorder or anticoagulant medication, while certain cases have shown that this disease is related with spinal inflammatory conditions. A SSEH tends to occur in patients who have risk factors for hemorrhage. However, the incidence of SSEH is quite low, and there are few domestic reports of a SSEH in young adults who are without the risk factors for hemorrhage. We encountered a 25 years old young male without a prior significant medical history and he was suffering from severe back pain and paraplegia due to a SSEH at the thoracic spine. The early diagnosis was made via MRI. We report here on a favorable clinical outcome that was achieved with immediate operative treatment, and we include a review of the relevant literature.

연구계획 : 척추골절의 치료를 위한 내고정시 사용되는 장분절 고정과 단분절 고정의 임상적 결과 및 차이점을 알아보고자 후향적 연구를 계획하였다. 연구목적 : 장분절 고정술과 단분절 고정술 사이에 역학적 견고성과 골절의 정복력, 신경학적 회복 정도와 임상적 결과를 비교, 분석하고자 하였다. 대상 및 방법 : 1989년부터 1997년까지 척추의 외상 환자중 후방도달법에 의한 척추경나사못 고정술을 시행한 54명 을 대상으로 장분절 고정군과 단분절 고정군으로 구분하였고 단분절 고정술의 경우 골절된 추체에도 척추경 나사 못을 삽입하였다. 단분절 고정군은 35례로 평균 1년 8개월 추시하였고 장분절 고정군은 19례였으며 평균 2년 7개월까지 추시하였다. 결과는 단순 방사선사진에서 전방추체 높이의 변화, sagittal index, 및 신경학적 회복정도를 비교하여 평가하였다. 결과 : 장분절 고정군에서 전방추체 높이는 술전 50.7%, 술후 78.7%, 최종 추시상 74.9 %이었고, 단분절 고정군에서 는 각각 59.7%, 79.3%, 및 77.7 %로 통계학적 차이가 없었다. Sagittal index는 장분절 고정군에서 술전 17.5。, 술후 6.7。, 최종 추시상 8。였으며 단분절 고정군은 19.9。, 10.4。, 및 12.1。로 차이가 없었다. 다른 임상결과도 양군간의 차이 는 없었다. 신경증상이 발생한 36례중 22례에서 Frankel분류에서 1등급 이상의 회복이 있었다. 결론 : 흉요추 및 요추 골절의 수술적 치료시, 골절된 추체를 포함하여 상하위 1추체씩 고정하는 추경나사못 사용 단분절 고정술이 권장할 만한 수술방법으로 사료된다. Study design : A retrospective study was designed to evaluate the clinical result and difference between short segment and long segment fixation, which was undertaken by posterior approach for thoracic and lumbar spine fractures. Objective : To determine and compare the mechanical maintenance and ability of correction, and clinical and neurologic recovery between short segment and long segment fusion group. Summary of Background Data : The long segment instrumentation is a cause of decrease of motion segment in thoracic and lumbar spine. In short segment fusion, screw failures were reported. Materials and Methods : From 1989 thorough 1997, 54 patients who had been operated on by the posterior approach with transpedicular screw fixation for spine injuries were divided into two groups. The authors applied the short segment transpedicular instrumentation including fractured vertebra. Short segment group included 35 cases, and long segment group, 19 cases. The mean follow-up period was one year and eight months for short segment group, two years and seven months for long segment one. The results were evaluated by comparing the anterior vertebral height, sagittal index in simple roentgenogram and neurologic recovery. Results : The average of anterior vertebral height which was 50.7% at preoperation, became 78.7% after the operation and measured 74.9% at final follow-up in long segment fusion group, while in short segment fusion group it was 59.7%, 79.3% and 77.7%, respectively. The average of sagittal index of 17.5°at preoperation became 6.7°after the operation, and measured 8。 at final follow-up in long segment fusion group, while in short segment fusion group it was 19.9。, 10.4。, and 12.1。, respectively. Overall clinical results had no statistical significant difference between two groups. Of the thirty-six patients with neurologic deficits, twentytwo improved by over the one Frankel grade. Conclusions : The authors conclude that the short segment transpedicular instrumentation including fractured vertebra is a successful method of thoracolumbar and lumbar burst fractures.

부신경절종은 발생학적으로 신경 능선 세포로부터 기원하는 종양으로 두경부에서 가장 많이 발생하나 드물게 종격동, 후복막 등의 내장 기관에서도 생기며 대부분 양성 경과를 보인다. 그 중 흉요추부의 경막내에 발생한 경우는 매우 드물며, 경추나 흉추보다는 요추부에 대부분 발생한다고 보고되었다. 지금까지 흉요추부의 부신경절종이 보고된 예는 드물기에 저자들은 부신경절종이 흉요추부의 경막내 수막외에 발생한 1예를 경험하여, 자기 공명 영상 및 조직학적 특징과 그 치료 결과를 문헌 고찰과 함께 보고하고자 한다. Paragangliomas arise from a multicentric system of paraganglion cells derived from the neuroectoderm. Although these tumors are the most common in the head and neck region, they may occur in diverse locations including mediastinum, retroperitoneum and visceral organs. Spinal paragangliomas arising in the intradural space of the thoracolumbar spine have been reported rarely, with the majority located in the cauda equina. Only few cases of thoracic paraganglioma have been previously reported. We present an additional case of thoracolumbar paraganglioma and review the clinical MRI and histopathological features of this unusual tumor.

鄭舜澤 木浦大學校 工業技術硏究所 1992 工業技術硏究誌 Vol.2 No.-

Rice, barley and sorghum soiu, the neutral unaged spirit of distillated alcoholic beverages, were distilled in a pot-still with a valve tray column. Those chemical composition, furfural, oxymethylfurfural and 5-methyl-2-furfural of products and distilled inetrmates were analized with gas chromatography to imvestigate the variation of it’s content according to the conditions of distillating process, and the odor threshold of furfural was determined. Sojus were generally distilled at no more than 30% alcohol and general constituent contents in soju were different a little, and content of furfurals were as follows ; rice soju 1.07, barley soju 1.26 and sorghum soju 1.66㎎/100㎖ were found. Composition of furfural, oxymethylfurfural and 5-methyl-2-furfural was 0.64, 0.66 and 0.07㎎/100㎖ in sorghum soju. Elution of those furfurals during distillating was that furfural were in 40~60% alcohol distillate and oxymethylfurfural were in potable middle alcohol and 5-methey-2-furfural were in tail. Odor threshold of furfural in 30% ethylalcohol sol. by sniffing were 30000 ppb and by tasting were 700 ppb. Odor unit value by tasting of furfural were 1.5~2.4 and by sniffing were 0.3~0.55.

Li was a sweet beverage containing 2-3 percents ethyl alcohol made from malt by spontaneous fermentation from ancient custom to fifteenth century. Li was changed to the rice wine being a sweet beverage of low alcohol content using nuruk as starter and the sikhae which is non-alcoholic fermented beverage. Li was made for drinking and ceremony in Korea, China and Japan. It disappeared from the beverage items along with its method of manufacture from malt, but in Korean had made Li using nuruk until recent. We made Li according to Book of Imwon-Keongjae Ji (The book of country economy) methods for reappearance of Li. Fermentation characteristics for the production of Li with Saccharomyces cerevisiae, Saccharomyces bayanus and Saccharomyces sake were investigated. Among the yeast strains tested, Li fermented with S. sake showed higher alcohol production. Total sugar decreased considerably during the whole period of fermentation(30 hours), while ethyl alcohol content increased at 2.9∼83.52%. As the fermentation progressed, the pH decreased until the 30 hours of fermentation, while total acid increased during the same period. In fermentation of 36 hours, Li consisted of about 2.98∼3.52% of alcohol content, 5.3∼6.0% of total sugar, 1.45∼2.21㎎% of reducing sugar and total acidity were reached up to 24.4∼29.5㎎% for Li manufactured with S. cerevisiea sake, S. bayanus and S. sake.

Study Design : This case report presents a 50-year-old patient with tabetic Charcot spinal arthropathy combined with spinal stenosis, and its management. Objectives : To present the case report and follow-up results of Charcot arthropathy with spinal stenosis of the lumbosacral spine, which was treated by circumferential fusion with instrumentation and decompressive laminectomy. Literature Review : Most reports of Charcot spine mention the etiology, clinical characteristics, pathology, and management of the condition. Surgical management of Charcot spines with spinal stenosis are rare. There is no report of the two-stage procedure of circumferential fusion and decompression for Charcot spine with spinal stenosis. Materials and Methods : The patient complained of back pain, radiating pain to both lower legs, and lOOm neurologic claudication. Serologic testing was positive in VDRL and FTA-ABS tests. Surgical treat vent consisted of anterior resection of the L5 body with an autogenous iliac bone graft. It was followed by a posterior wide laminectomy of L5 for spinal stenosis, and CD instrumentation with transpedicular screws was applied to L3-S1 with lateral bone graft. Results : At 27 months follow-up, clinical symptoms of back pain and radiating pain were disappeared. The patient walked without claudication, and satisfied with her condition. Firm bony fusions from L3 to S1 were obtained. There was no evidence of further destruction or neural compromise in the 27 months following surgery. Conclusion : A case of Charcot arthropathy of the lumbosacral spine with spinal stenosis of L3-5 and L5-S1 has been reported, and the pathology, clinical features, and management of this condition were discussed. Circumferential fusion for Charcot spine and wide decompressive laminectomy for spinal stenosis are advisable.
