The main goals of surgical teatment of thoracolumbar vertebral fractures are to achieve reduction, stability and early, painless mobilization. A further aim is to avoid late malposition and to preserve mobility and lordosis. The main disadvantage of Harrington instrumentation and similar methods are that this device fixate five to seven vertebrae. The Cotrel-Dubousset(C-D) instrumentation provides a stable construct for fixation of spine fracture. The advantages of C-D pedicle screw for thoracolumbar spinal fractures are that compression or distraction force can be applied in the same rod and used to achieve anatomical reduction of spinal fractures and rigid fixation can be obtained with short instrumentation. The C-D instumentation was done for 15 unstable thoracolumbar spinal fractures at Seoul Red Cross Hospital from January, 1988 to January, 1990. The results were as follows. 1. The most common cause of the spine fracture was fall down, and majority are within 20-40 old age. 2. The most common involved site was T12 and Ll vertebrae (66.7%). 3. The most common type of injury was burst fracture by according to Denis classification(60%). 4. The complication was developed mostly in neurological deficient patient. 5. The advantage of the C-D instrumentation: (1) rigid and short osteosynthesis of spine fracture, (2) compression or distraction force can be applied in the same rod, (3) early mobilization with a brace is possible. 6. The rigid fixation can be obtained.

Bone remodeling is characterized by the coupling of osteoclast-mediated bone resorption and osteoblast-mediated bone formation. The process is tightly regualted at the local level by an incompletely known netwotk of peptide and non-peptide fators. Nitric oxide(NO), synthesized by nitric oxide synthetase(NOS) from L-arginine, is becoming recognized as an important bioregualtory molecule in a variety of tissue, but little is known about its possible role in periodontal tissue. The purpose of this study is to investigate the expression of nitric oxide synthetase(NOS) in inflamed gingiva and the effects of cytokine on the expression of NOS protein. The expression of NOS in gingival tissue was evaluated by immunohistochemical staining for NOS1, NOS2, NOS3. The effect of cytokine on the expression of NOS in human periodontal ligament cells and osteoblast-like HOS cells by western blot analysis. Further, we studied that NO functions in periodontal ligment cells as a regulatory molecule. PDL cells incubated with NOS inhibitor and donor. The protein expression, type I collagen & non-collagenous protein, nitrate production and cell proliferation were evaluated The results were as follows. 1. NOS1, NOS2, NOS3 was rarely distributed in healthy gingiva, but stronger stained in gingival epithelium, endothelial cells, and mononuclear cells of inflammed gingiva. 2. The cytokine stimulated NOS1, and NOS3 protein were not inducing or inhibitory effect to compared with control in PDL and HOS cells. 3.Incubation of cells with combination of TNF-alpha, IFN-gamma, LPS result in a time dependant increase in NOS2 expression, reaching a maximal level after 24 hours of stimulation. 4. The osteonectin protein inhibitory effect of NMA, inhibitor of NOS, was reversed by Larginine in dose dependant manner. 5. NMA decreased cell proliferation and nitrate production, but the inhibitory efffect of NMA was also prevented by the NO donor, sodium nitropruiside. These results suggest that exogenously synthesized NO was playing a stimulating effect on cell proliferation or on non-collagenous protein expression. Therefore NO have an important role in mediation of localized bone destruction associated inflammatory bone disease such as periodontitis

OBJECTIVE: Over the last few years there has been growing concern about bulimia nervosa in Korea, but there was only a few clinical study, especially about outcome and predictors. CBT combined with pharmacotherapy has been recognized as the most effective short-term treatment modality, but there was nonresponders. The purpose of this paper is to examine the factors that influence treatment response and outcome in patients with bulimia nervosa. The identification of prognostic factors in bulimia nervosa will help clinicians to deliver the most appropriate type of initial treatment to patients. METHOD: The subjects were 62 patients from the outpatients of Mind & Mind psychiatric clinic, who had been previously evaluated by EDI-2 and MMPI. The sociodemographic data, disease progress, past history, family history, BMI, EDI-2 and MMPI were variables assessed. All patients received a 12-week course of CBT combined with pharmacotherapy (fluoxetine 20-60mg/d). Responders and non-responders group ware compared with each variables. Responders were defined as patients who had maximum symptom frequencies of three or less during the last 4 weeks of treatment. RESULT: Among 62 patients, responders were 32 and non-responders were 30. There was no difference in sociodemographic variables such as age, education level, job, marriage. As a result of comparing the two groups, non-responders were differentiated by their higher frequency of binge eating vomiting, history of suicide attempt, family history of psychiatric illness and use of laxatives or diuretics. And among the subscale of EDI-2, there were significant high scores in bulimia, ineffectiveness, interoceptive awareness. CONCLUSION: The findings suggest that frequency of binge eating, vomiting, history of suicide attempt, family history of psychiatric illness, and use of laxatives or diuretics could be prognostic factors in patients with bulimia nervosa.

Separation anxiety (SA) is a serious behavioral problem in dogs. In this study, salivary cortisol was studied to determine if the owner's odor or voice could reduce SA in dogs. Twenty-eight dogs with SA were divided into three groups: group 1 (control), group 2 (with owner's clothes during the separation period; SP) and group 3 (a recording of the owner's voice was played during SP). The dog's saliva was collected after the owner and their dog were in the experimental room for 5 min (PRE). The dog was then separated from the owner for 20 min and saliva collected four times at intervals of 5 min (SP1-4). Finally, the owner was allowed back into the room to calm the dog for 5 min, after which saliva was collected (POST). Evaluation of salivary cortisol concentrations by ELISA revealed that the ratios of SP1 concentration to PRE or POST concentrations were significantly higher in group 1 than in group 2 or 3. Additionally, the concentrations of SP1-PRE and SP1-POST among groups differed significantly. These findings indicate that the owner's odor or voice may be helpful to managing stress in dogs with SA.

An example of lymphoblastic lymphosarcoma was found in a 7-year-old male brown bear (Ursus arctos) that died after having a 7-month history of depression, anorexia and watery diarrhea. Grossly the mesenteric lymph nodes were enlarged to approximately 4 to 6 times their normal size and histologically diagnosed as lymphoblastic lymphosarcoma. The small intestinal mucosa was corrugated and had severe mural thickening due to infiltrated neoplastic cells. Hepatic metastasis was also noted. This is the first reported case of lymphosarcoma in Ursidae in Korea. As an incidental finding, endogenous lipid pneumonia was noted in the lung.

Prevalence survey of neurocysticercosis was made in a mixed epilepsy patients of Changmi Club in Korea. From February 1987 to July 1990, a total of 2,667 randomly selected patients at 27 local centers was tested for their serum levels of anti-Cysticercus antibody (IgG) by enzyme-linked immunosorbent assay. Positive rate of the antibody was 4.0% in the examined patients. The standardized antibody positive rate by provincial population was 3.1%. The rate was the highest in patients living in Cheju Do (8.4%). The patient age brackets of 0 approximately 9 years and over 50-year showed higher positive rates of the antibody. In 750 normal persons who checked up routine physical examination, the antibody positive rate was 2.1% (standardized rate was 1.8%). These seroepidemiological data disclosed for the first time the prevalence of cysticercosis in epileptic patients and in population.

Ectopia cordis is defined as a congenital malposition of the heart partially or completely outside the thorax and often associated with sternal and congenital heart defects:surgical repair is generally unsuccessful because of the magnitude of the deformity and the associat-ed intracardiac anormalies. Four types of ectopia cordis are described : cervical, thoracic, abdominal and thoracoa- bdominal. Cervical and thoracic type are often fatal within days, because the heart is expo- sed and malformed. Abdominal type carries a better prognosis because cardiac abnormalities are less often found. The prognosis of thoraco-abdominal type mainly depends on the pre- sence of intracardiac abnormalities. We have experienced a case of thoracic ectopia cordis at 25 weeks' gestation by ultra- sonography, so present the case and the review with literature briefly.

Autoimmune diseases are occasionally associated with other autoimmune diseases in the same patients. Graves disease has been associated with systemic rheumatic diseases including systemic lupus erythematosus (SLE). The diagnosis of Graves disease in patients with SLE is well known, especially in adults, but few case reports have involved children and adolescents. We report a 14-year-old female who presented with Graves disease, proteinuria, arthralgia, decreased complement, and positive antinuclear antibody and who was diagnosed with SLE. Renal biopsy revealed class IV lupus glomerulonephritis. These clinical, laboratory, and histological findings indicate that class IV lupus nephritis may be associated with Graves disease. This possibility should be borne in mind when following patients with Graves disease in order to avoid any delay in the diagnosis and treatment of serious systemic autoimmune diseases such as SLE.
