The spine can be divided into two structural columns; an anterior column consisting of vertebral bodies, discs and ligaments and a posterior column consisting of the neural arch, facet joints and interconnecting ligaments. Disruption of both anterior and posterior columns results in spinal instability. Laminectomy may produce greater spinal instability and will convert a stable injury into a unstable one. The compression that exists in these injury is anterior and therefore posterior laminectomy do little more than produce spinal instability. The technique of open reduction and Harrington rod fixation of unstable fractures improved nursing care, shortened rehabilitation and was effective in maintaining fracture reduction and promoting bony healing. Between 1978 and 1980, thirteen consecutive patient with unstable fractures and fracture-dislocations of thoracolumbar spine were treated by open reduction and spinal fusion with Harrington rod fixation at the Department of Orthopaedic Surgery of the Han Gang and Kang Nam Sacred Heart Hospitals. The following results were obtained from analysis of the cases. 1. The reduction and stability after reduction with Hsrrington instrumentation was excellent. 2. Laminectomy produced greater spinal instability. 3. Early ambulation was possible and the period of hospitalization was shortened. 4. Neurological recovery from incomplete neural deficit was good but from complete paraplegia was less effective.

PURPOSE: We studied enhanced method to view the vessels in the brain using Magnetic Resonance Angiography (MRA). Noticing that Maximum Intensity Projection (MIP) image is often used to evaluate the arteries of the neck and brain, we propose a new method for view brain vessels to stereo image in 3D space with more superior and more correct compared with conventional method. MATERIALS AND METHODS: We use 3T Siemens Tim Trio MRI scanner with 4 channel head coil and get a 3D MRA brain data by fixing volunteers head and radiating Phase Contrast pulse sequence. MRA brain data is 3D rotated according to the view angle of each eyes. Optimal view angle (projection angle) is determined by the distance between eye and center of the data. Newly acquired MRA data are projected along with the projection line and display only the highest values. Each left and right view MIP image is integrated through anaglyph imaging method and optimal stereoscopic MIP image is acquired. RESULTS: Result image shows that proposed method let enable to view MIP image at any direction of MRA data that is impossible to the conventional method. Moreover, considering disparity and distance from viewer to center of MRA data at spherical coordinates, we can get more realistic stereo image. In conclusion, we can get optimal stereoscopic images according to the position that viewers want to see and distance between viewer and MRA data. CONCLUSION: Proposed method overcome problems of conventional method that shows only specific projected image (z-axis projection) and give optimal depth information by converting mono MIP image to stereoscopic image considering viewers position. And can display any view of MRA data at spherical coordinates. If the optimization algorithm and parallel processing is applied, it may give useful medical information for diagnosis and treatment planning in real-time.

Hallux valgus has been defined as a static subluxation of the first metatarsophalangeal joint with lateral deviation of the proximal phalanx on the first metatarsal head from the longitudinal axis of the first metatarsal with medial deviation of the first metatarsal. And first-second metatarsal angle is increased as well as bursal hypertrophy over the medial eminence of the first metatarsal head. Many procedures have been reported for the treatment of the hallux valgus ranging from resection arthroplasty to distal first metatarsal or basal first metatarsal osteotomy. Of these, Johnson and Corless have required sufficiently good results in the modifying Mitchell osteotomy into Chevron osteotomy. The Chevron procedure is an osteotomy involving the distal portion of the first metatarsal, lateral displacement of the metatarsal head with exostosectomy, and tightening of the medial capsular structures. Authors studied 17 cases in 10 patients with the hallux valgus deformity treated by Chevron osteotomy at the Department of Orthopedic Surgery, Capital Armed Forced General Hospital from September 1987 to September 1989. The results were as follows; 1. Seven patients (12 cases) were male and three patients (5 cases) were female. All patients had bilateral hallux valgus deformity. 2. The average first-second intermetatarsal angle was 11 degrees and average valgus angle was 32 degrees, preoperatively. They were corrected to 9 degrees and 14 degrees respectively. 3. The metatarsalgia of the great toe was subsided in all cases and they were satisfied with the result of their operations in respect to cosmetically and functionally. Avascular necrosis of capital fragment, nonunion, and dorsal angulation were not developed in any case. But, one case had marginal skin necrosis, presumably due to excessive compressive dressing. 4. Chevron osteotomy is a technically easy procedure and it can be obtained early bone healing with less complication.

BACKGROUND: In chronic airway disease, mucus secretion in increased, but extraction of mucin, which is the main component of mucus secretion, is a very complicated and limited in clinical use. Recently, monoclonal antibody for mucin was developed for possible clinical use. In this study, cellular analysis and quantification of respiratory mucin in sputum of patients with chronic airway diseases were performed. METHOD: Sputum was collected from patients with asthma(n=33), bronchiectasis(n=8) or chronic bronchitis(n=13) by spontaneous expectoration or by hypertonic saline induction, Collected sputums was treated by 0.1% dithiotreitol to dissociate the disulfide bond of the mucus and filtered through a nylon gauze. Total cell count, viability and differential count were measured. For detection of mucin, collected samples were treated with sodium dodoecyl sulfate polyacrylamide gel electrophoresis and then with monoclonal antibody(HMO2), as the primary antibody, and PAS stain. The amount of mucin was measured with ELISA by HMO2. Correlation with clinical information, cellular analysis, and amount of measured mucin were analyzed. RESULTS: Total cell counts of sputum were significantly increased in patients with bronchiectasis but viability remained the same. Eosinophils were significantly increased in patients with asthma, neutrophils in bronchiectasis chronic bronchitis, respectively (p<0.05). The results of Western blotting and PAS staining confirmed the presence of glycoproteins and matched? with mucin. The amounts of mucin measured by ELISA were not significantly different among the disease groups. Significant correlation was identified between the amount of mucin and viability(r=-0.482, p<0.05). CONCLUSION: Inflammatory cells in the sputum of those with chronic airway disease were different for each disease type. Measurement of mucin by ELISA via monoclonal antibodies may be a simple method for the evaluation of chronic airway disease.

BACKGROUND: An increase in oxidative stress has been suggested to play major roles in the complications of diabetes. The bulk of the experimental data favors enhanced free radicals in diabetes and antioxidant defense mechanisms may be reduced in diabetes. Melatonin, the major secretory product of the pineal gland has been shown to be a potent and specific hydroxyl radical scavenger. The purpose of our study was to determine the antioxidative effeet of melatonin in streptozotocin-induced diabetic rats. METHODS: Sprague-Dawley rats weighing 200-240 g were divided into 3 groups: normal controls(n-7), diabetic contmls(n-9), melatonin-treated diabetic animals(n-9). Diabetes was induced by intraperitoneal injection of streptozotoein(55 mg/kg body weight) and melatonin(6 mg/kg body weight) was orally administered for 20 days. At day 20 after streptozotocin administration, blood was collected for the assay of glucose, albumin and cholesterol. Erythrocyte membrane lipid peroxidation was determined by malonyldialdehyde(MDA) reactivity. RESULTS: 1) The MDA resctivity of erytbrocyte membrane in melatonin-treated diabetic animals (meanstandard deviation: 5.52+-1.52nmol/ml packed cells) were lower(p<0.05) than that in diabetic controls(7.68+-1.16nmol/mL packed cells). But, there was no significant difference between melatonin-treated diabetic animals and normal contls(4.93+-1.19 nmol/mL packed cells). 2) There were no significant differences of blood glucose and body weight between diabetic controls and melatonin-treated diabetic animals. CONCLUSION: These results show the antioxidative effect of melatonin in streptozotocin-induced diabetic rats. Further clinical and long-term experimental studies are needed to assess the effect of melatonin on development and progression of diabetic complications.

Diverticulum of the vermiform appendix is infrequently encountered, and in the absence of inflammation, it has been reported to be asymptomatic. Furthermore, hemorrhage from an appendiceal diverticulum is extremely rare, and has not yet reported in our country. We report a case of hemorrhage occurring in appendiceal diverticulum.
