  • An appearance of herniated intervertebral disc into thoracolumbar vertebral canal was evaluated in two patients using computed tomography (CT). Before CT scanning, plain radiography and myelography were performed in both cases. CT images were compared to those of myelography. Dogs were positioned in sternal recumbency under inhalation anesthesia and transverse slices with 2 mm thickness were obtained around thoracolumbar region. The transverse CT images were examined using both vertebral and spiral window mode. The most common findings on CT images were loss of vertebral canal epidural fat, bulging of vertebral canal disc margins, displacement of spinal cord and flatted vertebral canal. Whereas, narrowed intervertebral disc space and simple extradural pattern were the main findings on plain and contrast radiographs. CT imges showed the extent of the herniated disc lesion, type II intervertebral disc hernation, and the displacement of spinal cord in detail in both occations. It is considered that degree and precise localization of the intervertebral disc herniation and subtle lesion of spinal cord could be identified accurately using computed tomography.

  • A 10-month-old intact male Scottish Fold was presented with cardiomegaly. The cat showed exercise intolerance after birth. Radiographs showed cardiomegaly with bulging of the main pulmonary artery and dilation of pulmonary arteries. Echocardiogram revealed abnormally arisen aortic root toward right ventricle with left-to-right shunted perimembraneous ventricular septal defect located underneath the aortic root. Based on imaging studies, the cat was diagnosed as subaortic type of double outlet right ventricle (DORV) without concurrent abnormalities.

  • A 2-year-old, spayed female, American shorthair cat presented with acute weight loss, tachypnea, and dyspnea. The cat had grade V holosystolic murmur and systemic hypotension. Echocardiography showed a 9 mm defect in the ventricular septum, left-to-right dominant bi-directional shunt, right ventricular hypertrophy, pulmonary stenosis, pulmonary hypertension, and overriding aorta. The cat was diagnosed with a Tetralogy of Fallot. The cat was treated with furosemide, pimobendan, ramipril, and sildenafil. Treatment reduced pulmonary infiltration, pulmonary vessel enlargement, and main pulmonary artery bulging. However, right-to-left flow increased over time and right ventricular outflow tract velocity was elevated. Currently, the patient has maintained an improved state for 1 year. This case report described a severe inherited feline Tetralogy of Fallot case that was successfully managed for a long time.

  • Objectives : The purpose of this study is to find out the characteristics of intervertebral disc changes and relative factors of the spondylolisthesis patients in fifties by type of spondylolisthesis. Methods : We investigated 69 cases of patients who visited one Korean traditional medicine hospital and were diagnosed as spondylolisthesis on L-spine X-ray and L-spine magnetic resonance imaging(MRI). We selected 37 lytic spondylolisthesis patients and 32 degenerative spondylolisthesis patients. We analysed the relativity between the numbers of changed discs, types of changed disc, locations of nerve compression and types of spondylolisthesis. Results : 1. The number of changed discs increase in lytic type, but there is no statistically significant difference. 2. Bulging disc is the dominant type of disc change. There is no significant difference between two types. 3. Both foraminal type was shown dominantly in lytic spondylolisthesis, diffuse type in degenerative spondylolisthesis by the analysis of the location of the nerve compression. But the symptoms of patients and dermatome did not match in most of the cases. Conculsions : The direction of nerve compression is different while the disc changing aspects are similar in both types. In several spondylolisthesis patients in fifties, symptoms of patient are related to degeneration of vertebrae, not to the type of spondylolisthesis.

  • The upper bound elemental technique (UBET) is used to simulate the bulk flow characteristics in axisymmetric closed die forging process. Internal flow inside the cavity is predicted using a kinematically admissible velocity field that minimizes the rate of energy consumption. Application of the technique includes an assessment of the formation of flash and of degree of filling in rib-web type cavity using billets with various aspect rations. The technique considering bulging effect is performed in an incremental manner. The results of simulation show how it can be used for the prediction of forging load, metal flow, and free surface profile. The experiments are carried out with plasticine. There are good agreements in forging load and material flow in cavity between the simulation and experiment. The developed program using UBET can be effectively applied to the various forging problems.

  • Plexiform neurofibromas (PNFs) represent an uncommon variant (30%) of neurofibromatosis type 1 (NF-1), in which neurofibromas arise from multiple nerves as bulging and deforming masses involving connective tissue and skin folds. We report the case of a 17-year-old man with known NF-1 presenting with bilateral occipital neuralgia that began in his late adolescence. His chief complaint was radiating pain in the occiput induced by protective helmet wear when riding alpine skiing. Craniofacial magnetic resonance imaging (MRI) confirmed the presence of fusiform masses arising from the bilateral greater occipital nerves. Histopathological examination of the biopsy samples showed PNFs. After surgical treatment, the patient's symptoms completely improved. Unlike cutaneous neurofibromas, PNFs have different clinical characteristics and have the risk of malignant mutations. Correct diagnosis and adequate surgical treatment are necessary for PNFs.

  • Purpose: It is generally accepted that anatomical structures of the soft tissue in Asian faces are quite different from those in Caucasian. It is presumed that these differences are due to collagen rich thick dermis and durable superficial musculo-apponeurotic system (SMAS) in Asian. We classified the aging lower eyelids and reviewed the operative procedures according to the types of aging lower eyelids in Asian. Methods: We compared preoperative and postoperative photos of 117 patients over 30 years of age, who underwent lower blepharoplasty at the Kyunghee Medical Center from January 2001 to April 2006. We classified the patients based on the degree of skin laxity, presence of nasojugal groove and malar bag, the extent of aging process. We also reviewed the operative procedures according to each type of classification. Results: We classified our patients into four types as following. Type I patients showed minimal skin-muscle excess confined to lower eyelids regardless of the facial line. For these patients, we performed only transcutaneous or transconjunctival blepharoplasty. In type II patients, nasojugal grooves were shown and skin- muscle laxity was limited to the medial side of imaginary vertical line at lateral margin of pupil. In these cases, we performed free fat graft or fat repositioning on nasojugal groove or fat removal and septal duplication confined to medial side. Type III patients displayed more advanced medial bulging and remarkable laxity over the lateral side, the same operation methods as those of type II were applied at the lateral side of the line. Type IV patients demonstrated extensive midfacial aging changes including malar bags and underwent superficial subciliary cheek lift. Conclusion: The lower eyelid aging of Asian is different from those of Caucasian. We think that our classification is useful in selection of appropriate operative procedure to address specific problems for Asian patients.

  • This study aims to use the avatar sizing system of the 3D apparel CAD program instead of the existing 3D body scanners, and to commercialize 3D personal avatars. Towards these ends, the study examined a difference between a 3D avatar and actual body was determined to verify the 3D avatar sizing system. For the experiment, three subjects were selected, were measured as they were, and were made to undergo 3D body scanning and photographing. Then, using avatar sizing system on the 3D apparel CAD program, three types of virtual bodies, namely 3D avatars. The 3D avatar and actual body measurements were compared, and 3D avatars and 3D body-scanned shapes were likewise compared. As a result, the three types of actual bodies and their 3D avatars that were created based on the sizing system of the 3D apparel CAD program were overall similar. but, the thin body-YY type and the normal body-A type were different from their avatars. In the case of type B, who had a bulging abdomen, the 3D avatar was bigger than the actual body as measured. Also, in all body shapes, the girths around the chest, waist and abdomen were produced with exaggerated muscular amounts compared to their actual muscular amounts.

  • It has been a puzzle in solar physics how a low-lying magnetic structure such as a solar prominence surrounded by a strongly line-tied overlying field sometimes intrudes through the latter and goes into eruption. A numerical simulation study of the solar coronal plasma reveals that a ballooning instability can explain this type of eruptive process. We consider an idealized situation with two flux ropes merging. When magnetic field lines from different flux ropes reconnect, a new field line connecting farther footpoints is generated. Since the field line length abruptly increases, the field line expands outward. If the plasma beta is low, this expansion takes place more or less evenly over the whole field line. If, on the other hand, the plasma beta is high enough somewhere in this field line, the outward expansion is not even, but is localized as in a bulging balloon. This ballooning section of the magnetic field penetrates out of the overlying field, and eventually the originally underlying field and the overlying field come to interchange their apex positions. This process may explain how a field structure that has stably been confined by an overlying field can occasionally show a localized eruptive behavior.

  • This report deals with the morphology of the horsehair worm isolated in canine vomitus. We received a worm in living status. The worm was investigated by using light and scanning electron microscopy (SEM) for species determination. Grossly, the worm was blackish brown in color and 215 mm in length and 1.2 mm in maximum width. Microscopically, the worm was composed of epicuticle, cuticle, epidermis, muscle, mesenchyme, pseudocoel, nerve cord and gut. But the genital organ was not developed. The SEM study revealed that the cuticle contains five types of elevated structures called areoles. The cuticular surface of the parasite is covered by an abundant type of areoles: simple areole, tubercle areole, bulging areole, crowned areole, circumcluster areole. The observed characteristics of the specimen in this study are same to those of genus Chordodes. And we concluded that it is a male of Chordodes koreensis belong to Gordiida. Only nine species of freshwater Nematomorpha are known from Korea, two of which belong to the genus Chordodes. But the case of parasitic horsehair worm in dogs do not recorded, and this is a first gordiosis of dog in Korea.
