Many authors reported the etiology of hypoplasia of the nasomaxillary complex as trauma, infection, underdevelopment. To correct these deformities, Le Fort II Osteotomy and its modification has been popularly applied. This method enabled total advancement of nasomaxillary complexes and acquirememt of midfacial esthetics. But it has some limitations such as various occlusal deviation or lateral shifting of nasomaxillary complex in case of nasomaxillary retrusion. We grouped these patients as follows : 1. Nasomaxillary retrusion without shifting of nasomaxillary complex (1) Anteroposterior deviation of occlusal plane (2) Lateral deviation of occlusal plane(including canting) (3) Supero-inferior deviation of occlusal plane (4) Combined disturbance of occlusal plane without shifting of nasamaxillary complex 2. Lateral shifting of nasomaxillary complex with or without deviation of occlusal plane We performed Le Fort II and I combined osteotomy on eleven cases of midfacial deformity from June 1994 to July 1997 and in most of the cases, followed up maximum 36 months and could acquire positional stability and improvement of facial eathetics.

Positron emission tomography (PET) with 2-[F-18]-Fluoro-2-deoxy-D-glucose (FDG) was performed in ninteen patients who had benign musculoskeletal tumors in order to determine if there was a relationship between histologic grade of tumor and FDG uptake of tumor. These patients had been evaluated previously with computed tomography (CT) or magnetic resonance (MR) imaging or both. The diagnoses were confirmed with incisional or excisional biopsy or by radiographic follow-up. Generally high-grade tumors had significantly greater uptake of FDG than low-grade lesions . Benign lesions such as giant cell tumor, fibrous dysplasia, and osteofibrous dysplasia showed significant elevation of SUV (Standardized Uptake Value) above 4.0. On the contrary. The current studies suggest the utility of FDG-PET imaging as an adjunct to CT or MR imaging in the evaluation of benign tumors. And results of PET suggest benign tumors with high SUV are histologically active lesion and tend to be locally aggressive.

Lipoma of the gastrointestinal (GI) tract is a rare disease, 0.1~0.3% of all diseases involving the gastrointestinal tract. As the size increases, the symptoms which develop are GI bleeding, abdominal pain, intussusception, intestinal obstruction. To the best of our knowledge no lipoma of gallbladder been reported yet. Furthermore a lipoma cannot develop in the GB, because the submucous layer is not existed. From a point of view for the mechanism, it is important for submucous layer, which is infiltrated by eosinophil or lymphocyte, to develop the lipoma of GB. We experienced the case of a 51-year-old female with a GB lipoma, and we report our experience with that case along with a review of the literatures about the most likely mechanism for the development of the GB lipoma.

To analyse the age of onset, etiologic microorganisms, clinical manifestations, managements and genetic variation of chromic granulomatous disease, the authors reviewed four patients who were diagnosed as CGD at Department of Pediatrics, Seoul National Univesity Children's Hospital. They were siblings in relationship-two of them were brothers, the others were brother-sister. @ES The results were as follows; 1) Initial manifestations developed within 1 year old, and lymphadenopathy associated with BCG vaccination was the most common. 2) In culture study of micro-organism, catalase positive microorganisms such as Staphylococcus aureus, Serratia marcescens, Coagulase (-) Staphylococcus, Enterococcus, Proleus vulgaris, Klebsiella pneumoniae, E. coli and fungus such as Candida albicans were isolated. In 2 cases, culture study revealed no growth. 3) Fever, lymphadenopathy, hepatomegaly, suppurative dermatitis and pneumonia were the most common manifestations. In most of cases, antituberculous medications were administered under the impression of tuberculosis without response. 4) Immunologic screening tests including B-cell system, T-cell system, and complement system were within normal limit except NBT test. 5) In spite of severe infections, NBT scores of all the cases were less than those of controls. Liver biopsies of 3 cases showed granuloma formation with characteristic yellow brown pigment-laden macrophages.

This study was undertaken to investigate the relation between orthodontic force magnitude and the amount of tooth movement. And more light force application for reducing root resorption. Twenty-four rats were divided into three experimental groups(A, B, C) based on force magnitude and application method. Springs of 50g force were applied to A group, spring of 100g force were applied to B group and springs of 25g force were applied to C group initially, and after 4 days springs of C group were changed to springs of 50g force. Two kinds of sentalloy(R) (GAC U.S.A) closed coil spring, 50g and 100g, were used. And we made 25g springs by heat treatment process of 50g spring. Each spring was inserted between the maxillary central incisor and the maxillary left first molar. Amounts of tooth movement were measured everyday by digital caliper(Digimatic(R) , Mitutoyo, Japan) under inhalation anesthesia for 15 days, all rats were sacrificed and histological sample were obtained with Hematoxyline-Eosin stan and Masson's trichrome stain. Following conclusion were made : 1. Group B showed the mean cumulative tooth movement of 2.19+/-0.41mm at 15th day, which was greatest among three groups, followed by group C(2.06+/-0101mm), group A(1.90+/-0.49mm) respectively. However, there was no statistically difference among three groups. 2. All groups showed general tooth movement pattern and A, B, C group finished lag phase at 9th, 8th, 7th day, but three was no statistical significance. 3. Group A, B, C showed root resorption and especially group B showed the most severe root resorption and group C showed milder root resorpting than other groups. According to the above results, large initial force with the development of a fairly widespread hyalinized zone may cause severe root resorption, so initial force should be applied lightly to reduce hyalinized area and eventually root resorption and then increased force will induce efficient tooth movement.

BACKGROUND: Spinal cord ischemic injury during thoracic and thoracoabdominal aortic surgeries remains a potentially devastating outcome despite using various methods of protection. Neuronal voltage-dependent sodium channel antagonists are known to provide neuroprotection in cerebral ischemic models. This study was designed to compare the neuroprotective effects of phenytoin with those of hypothermia in a rabbit model of spinal cord ischemia. MATERIAL AND METHOD: Spinal cord ischemia was induced in New Zealand white rabbits by means of infrarenal aortic cross clamping for 25 minutes. Four groups of 8 animals each were studied. The control group and the hypothermia group received retrograde infusion of saline only (22degrees C, 2 mL/min); the normothermic phenytoin group and the hypothermicphenytoin group received retrograde infusion of 100 mg of phenytoin at different rectal temperatures (39degrees C and 37degrees C, respectively) during the ischemic period. The neurologic function was assessed at 24 and 72 hours after the operation with using the modified Tarlov criteria. The spinal cords were harvested after the final neurologic examination for histopathological examination to objectively quantify the amount of neuronal damage. RESULT: No major adverse effects were observed with the retrograde phenytoin infusion during the aortic ischemic period. All the control rabbits became severely paraplegic. Both the phenytoin group and the hypothermia group had a better neurological status than did the control group (p<0.05). The typical morphological changes that are characteristic of neuronal necrosis in the gray matter of the control animals were demonstrated by means of the histopathological examination, whereas phenytoin or hypothermia prevented or attenuated these necrotic phenomena (p<0.05). The number of motor neuron cells positive for TUNEL staining was significantly reduced, to a similar extent, in the rabbits treated with phenytoin or hypothermia. Phenytoin and hypothermia had some additive neuroprotective effect, but there was no statistical significance between the two on the neurological and histopathological analysis. CONCLUSION: The neurological and histopathological analysis consistently demonstrated that both phenytoin and hypothermia may afford significant spinal cord protection to a similar extent during spinal cord ischemia in rabbits, although no significant additive effects were noticed.
