BACKGROUND: For gastric cancer, primary prevention by risk factor modification might have some important roles. However, previous studies having investigated the factors associated with stomach cancer reported various results. In addition, there were only a few studies based on Korean population. METHODS: A case control study was carried out on 106 cases matched for age and sex with 106 controls in a tertiary care hospital. In patients who were aged 75 years or less and had been newly diagnosed as adenocarcinoma of stomach between July 1996 and January 1997 were included into the case group. Information on baseline characteristics, health habits, dietary habits of study subjects was obtained through an interview using structured questionnaire. Conditional logistic regression analysis was used to evaluate the factors associated with stomach cancer. RESULTS: Salt preference was associated with significantly increased risk of stomach cancer (odds ratio[OR]=9.81, 95% confidence interval[CI]=2.28 42.2). Eating broiled food more than three times a week significantly increased the risk of stomach cancer (OR=3.33, 95% CI=1.16 9.55) compared to eating it less than once a week. Blood type, family history of stomach cancer, smoking, and alcohol consumption were not associated with stomach cancer. CONCLUSION: Salt preference and frequent eating of broiled food are the risk factors significantly associated with stomach cancer in this study subjects.

PURPOSE: The study is designed to develop an educational CD-Program for prevention and control of obesity among primary school students. METHOD: The study is conducted from June 15, 2000 to April 15, 2002. Based on the course of program development suggested by Dick and Cray (1990), the study followed the planning, development, education and evaluation of a program. RESULT: The developed CD-Program consists 2 parts each for lower and higher grades of primary school students. The introduction part of the first trial for lower grade students uses quiz to encourage their motivations, the body proceeds with motion pictures and animations to trigger their interests. The introduction part of the second trial for the lower grades consists of remembering the exhibition lecture. The first trial for higher grades of primary school students builds on the contents of the low grades. Its body part, how to determine obesity and calculate ones own obesity, puts ones own weight and height in by the mouse. For the second trial of the higher grades, the body consists of life-style, diet, and regiments. CONCLUSION: The merits of this CD-Program are that to be possible an interaction between teachers and students.

We studied ninety cases of thyroid glands both histopathologically and by immunohistochemical methods in patients with Graves' disease using B and T cell markers to evaluate the role of lymphocytic subpopulation. Females were affected more frequently than males with a ratio of 6.5:1, and usually the females were younger than the males at the time of surgery. The heavier the lymphocytic infiltration, the higher was the percentage of germinal center formation or fibrosis. The degree of lymphocytic infiltration was also related to the titers of antithyroglobulin or antimicrosomal antibodies. T cells were mostly scattered individually or in small groups between the follicles; however, in the severely infiltrated group, the major pattern was in clusters. T8 positive cells were more abundant than T4 positive cells, and their distribution pattern was accordant with T11 positive cells. Immunoglobulin synthesizing B cells were positively stained in 47 of 94 cases tested and IgG was the most predominant. In the mild and moderate lymphocytic infiltration groups, IgM was mostly stained at the mantle zone or in the lymphoid cluster of the interfollicular stroma, whereas IgM positive cells were present exclusively in the germinal center of the severely infiltrated group. The results of our study indicate that the major lymphocyte subpopulation in Graves' disease is B lymphocytes, and the degree of T lymphocytic infiltration correlated better with titers of antimicrosomal antibody than antithyroglobulin.

STATEMENT OF PROBLEM: It is important to have a correct presurgical treatment plan before any implant surgery. It must contain substantial information about the patient concerned. However, the standard classification only notifies the dentist about various structural, pathological and physiological dimensions. Due to diverse structure of the jaw bone, current standard classification does not tell spatial dimensions of the available bone for implant insertion sites. PURPOSE OF STUDY: The purpose of this study is to report the establishment of the systematic implant treatment plan and its clinical treatment using Implan(R) program which is based on ASCIi-classification that is available for future diagnosis and scale of treatment and for systematic implant insertion. RESULTS: By assisting the systemic measurement of the available alveolus dimension during implant surgery, it was easy to set initial implant treatment plan. CONCLUSION: Using Implan(R) program which is based on ASCIi-classification system that allows the establishment of systemic implant treatment plan and successful clinical performance, it was possible to establish the founding of initial implant treatment plan, the acquisition of information, and the systematization of documentation.

PURPOSE:
To identify the key CT features of lung parenchyma over time after cardiopulmonary resuscitation (CPR).
MATERIALS AND METHODS:
In total, 72 patients underwent CT after CPR. Because the median time from return of spontaneous circulation (ROSC) to CT was 1 h 3 min, we divided patients into two groups: ≤ 1 h (group 1) and > 1 h (group 2), based on the ROSC to CT time. We analyzed and compared various lung parenchymal CT findings between groups.
RESULTS:
Each group included 36 patients. Using statistical analysis, we identified seven statistically significant imaging features. Gradient (p = 0.010), lobular gradient (p = 0.017), diffuse pattern (p = 0.000), upper distribution (p = 0.032), and peripheral portion sparing (p = 0.000) were more common in group 1 than in group 2. Dependent density (p = 0.010) and lobular consolidation (p = 0.010) were more common in group 2 than in group 1.
CONCLUSION
The gradient and lobular gradient tended to disappear over time after ROSC. In terms of distribution, a diffuse pattern with upper predominance and peripheral portion sparing tended to disappear over time. However, the dependent density and lobular consolidation tended to increase over time in the lung parenchyma after CPR.

We present a case of 44-year-old male with spontaneous right vertebral arteriovenous fistula associated with neurofibromatosis type 1. The symptom of this patient was myeloradiculopathy of which was due to compressed cervical spinal cord by enlarged epidural vein. Complete occlusion of the fistula using coils resulted in relief of the patient symptom and complete disappearance of enlarged epidural vein on follow-up MR image one month later.

Short stature homeobox-containing gene (SHOX) is a well-known causative gene for the short stature in Turner syndrome. The clinical manifestation of SHOX gene related disorders varies from SHOX haploinsufficiency, presenting with idiopathic short stature, disproportionate short stature, or Leri-Weill dyschondrosteosis (LWD) to recessive form of extreme dwarfism and limb deformity in Langer mesomelic dysplasia. LWD is usually diagnosed upon suspicion based on short stature and skeletal abnormalities, and it is rarely accompanied with respiratory failure in the neonatal period. Here, we report the case of a newborn infant with LWD presenting with severe micrognathia that caused respiratory distress, which was diagnosed using microarray testing. Even when the manifestation of Madelung deformity is not yet apparent, LWD should be considered as one of underlying diseases related to congenital micrognathia.

PURPOSE: The aim of this study was to evaluate the heat generation in bone in vitro during the guided flapless drilling procedure and the effect of drilling methods on the heat generation. MATERIALS AND METHODS: A model that has missing the first and second mandibular molars bilaterally was used. In group A, classical flap implant surgery was performed. In group B, flapless implant surgery using surgical guide was performed. In group C, flapless implant surgery using surgical guide without up-and-down pumping motion was performed. Temperature was measured with k-type thermocouple and a real-time digital thermometer. The thermocouples were placed at 0.5 mm away from the osteotomy area at the depths of 3 mm and 6 mm. The measured values were evaluated with independent t-test. RESULTS: The mean temperature generated was 27.2degrees C (SD +/- 2.1degrees C) and 27.5degrees C (SD +/- 2.3degrees C) for groups A and B, respectively. These differences were not statistically significant. In group C, the mean temperature was 37.0degrees C (SD +/- 3.4degrees C). There were statistically significant differences between groups B and C with respect to the mean temperature. CONCLUSION: These findings suggest that guided flapless drilling with up-and-down pumping motion may not significantly increase the bone temperature.

Atherosclerosis is characterized by a chronic inflammatory disease, and chemokines play an important role in both initiation and progression of atherosclerosis development. Leukotactin-1 (Lkn-1/CCL15), a new member of the human CC chemokine family, is a potent chemoattractant for leukocytes. Our previous study has demonstrated that Lkn-1/CCL15 plays a role in the initiation of atherosclerosis, however, little is currently known whether Lkn-1/CCL15 is associated with the progression of atherosclerosis. Matrix metalloproteinases (MMPs) in human coronary atherosclerotic lesions play a crucial role in the progression of atherosclerosis by altering the vulnerability of plaque rupture. In the present study, we examined whether Lkn-1/CCL15 modulates MMP-9 release, which is a prevalent form expressed by activated macrophages and foam cells. Human THP-1 monocytic cells and/or human peripheral blood monocytes (PBMC) were treated with phorbol myristate acetate to induce their differentiation into macrophages. Foam cells were prepared by the treatment of THP-1 macrophages with human oxidized LDL. The macrophages and foam cells were treated with Lkn-1/CCL15, and the levels of MMP-9 release were measured by Gelatin Zymography. Lkn-1/CCL15 significantly enhanced the levels of MMP-9 protein secretion from THP-1 monocytic cells-derived macrophages, human PBMC-derived macrophages, as well as macrophage-derived foam cell in a dose dependent manner. Our data suggest that the action of Lkn-1/CCL15 on macrophages and foam cells to release MMP-9 may contribute to plaque destabilization in the progression of atherosclerosis.
