PURPOSE: This study was to investigate factors influencing the Framingham risk score-Coronary heart disease (FRS-CHD) according to gender and body mass index (BMI) of adults who participated in the 5th Korea National Health and Nutrition Examination Survey (KNHANES V-3). METHODS: This study used a cross-sectional design with secondary analysis with KNHANES V-3. The FRS-CHD scores were measured with ages, sex, blood pressure, cholesterol, high density lipoprotein, smoking, and diabetes mellitus. With demographic characteristics, family history of ischemic heart disease, types (intensity) and days of physical activities, perceived stress, drinking, menopause (in female), and BMI scores were measured. The data were analyzed with descriptive statistics, Pearson's correlation coefficients, and multiple regressions. RESULTS: FRS-CHD was significantly associated with types (intensity) and days of physical activities, educational level, occupation, and marital status, explaining 19.1~76.8% of the variance in men. FRS-CHD was significantly associated with types (intensity) and days of physical activities, menopause, and education level, explaining 55.0~59.5% of the variance in women. CONCLUSION: Factors influencing FRS-CHD were significantly different according to gender and BMI. To reduce the risk of coronary artery disease, it is necessary to develop gender-specific physical activity programs according to BMI.

Lipoid pneumonia is chronic, interstitial, proliferative inflammation resulting from aspiration of lipoid material. Mineral oil is a hydrocarbon that physicians often use to treat chronic constipation in children and adults. Mineral oil may not elicit a normal protective cough reflex and may impair mucociliary transport. We experienced a case of exogenous lipoid pneumonia caused by aspiration of mineral oil given as a laxatives confirmed by fiberoptic bronchoscopy with bronchoalveolar lavage and bronchial biopsy in a 9-month-old boy with chronic cough and radiologic evidence of parenchymal lung disease.We reported this case with a brief review of related literatures.

This study was performed to evaluate the influence of clonidine pretreatment on the car- diovascular toxic effects of bupivacaine overdose induced by constant intravenous infusion. Thirty male rabbits were used for this study and they were divided into saline pretreatment group(15) and clonidine-pretreatment group(15). The changes of mean arterial pressure, heart rate and electrocardiogram by the bupivacaine-induced toxic effect during intravenous infusion of bupivacaine were observed. The results were as follows; 1. Mean arterial pressure was significantly decreased in clonidine-premedicated group compared with control group (P<0.01) before infusion of bupivacaine, but the times occuring 25% and 50% decrease of mean arterial pressure were significantly prolonged in clonidine group compared with control group (P <0.001 ). 2. Heart rate was significantly decreased in clonidine group compared with control group (P<0.01) before infusion of bupivacaine, but the times occuring 25% and 50% decrease of heart rate were significantly prolonged in clonidine group compared with control group (P< 0.001). 3. The times occuring the first QRS modification and first dysrhythmia and the final systole were significantly prolonged in clonidine group compared with control group (P < 0.001). In conclusion, clonidine given prophylactically delays the cardiotoxicity caused by bupivacaine overdose snd does not accentuate the subsequent hypotension.

The present study evaluated the effect of various dosages of soybean isoflavone extract on body weight changes, glucose tolerance and liver function in streptozotocin-induced diabetic rats. One group of normal rats (normal control) was fed an AIN-76-based experimental diet and four groups of diabetic rats were fed the same diet supplemented with four different levels of soybean isoflavone extract for seven weeks. The daily dosages of pure isoflavone for four diabetic groups were set to be 0 mg (diabetic control), 0.5 mg (ISO-I), 3.0 mg (ISO-II) and 30.0 mg (ISO-III) per kilogram of body weight, respectively. The daily consumption of isoflavone at the level of 3.0mg per kilogram of body weight resulted in the suppression of body weight loss and increased the survival rate of diabetic animals one and half times compared to that of the diabetic control group. Blood glucose levels in a fasting state and after the oral administration of glucose were significantly lower in the ISO-II group during the oral glucose tolerance test. The ISO-II group showed a tendency to elongate the gastrointestinal transit time. The activity of serum aminotransferases, indicator of liver function, was not negatively affected by any intake level of isoflavone. The present study demonstrated that the soybean isoflavone extract may be beneficial to diabetic animals by improving their glucose tolerance and suppressing weight loss without incurring hepatotoxicity at the daily dosage of 3.0 mg per kg of body weight.

BACKGROUND: The concept of "neovascularization", which was first applied to describe the pathogenesis of diseases such as diabetic retinopathy or rheumatoid arthritis, has been extended to other fields of study such as myocardial ischemia and tumorigenesis. Endothelial progenitor cells (EPCs), play a critical role in neovascularization and have been reported to also be capable of colonizing vascular grafts. In this study, EPCs were isolated from cord blood, peripheral blood and bone marrow, and then cultured. Various cytokines, such as vascular endothelial growth factor(VEGF), Insulin growth factor(IGF), endothelial growth factor(EGF) fibroblast growth factor-basic(FGF-b), stem cell factor(SCF), flt3-ligand(FL), and thrombopoietin(TPO) were added to the cultures and observed for their effects on endothelial cells for their potential use in antineoplastic therapy or treatment of regional ischemia. METHODS: The mononuclear cells (MNCs) were isolated from cord blood, peripheral blood buffy coat, and bone marrow. They were collected from healthy donors using Ficoll-Hypaque. CD34+ cells were isolated by MACS system. To evaluate the effect of various cytokines, purified CD34+ cells were cultured under conditions of various cytokine combinations including SCF, Fl, TPO, VEGF, EGF, IGF, and FGF-b. After four weeks of culture, umbilical cord blood and bone-marrow derived adherent cells were analyzed for endothelial markers by immunohistochemical stain. RESULTS: Cultured adherent cells expressed the endothelial specific markers, such as KDR, CD34, CD31, CD62E, and CD cadherin but did not express vWF antigen. Typical morphology of endothelial cells was observed, such as the cord-like structure and cobblestone appearance during the culture period, which suggested that the adherent cells were consistent with endothelial cells. CONCLUSION: We described the experimental conditions in which endothelial progenitors were differentiated from CD34+ cells isolated from three hematopoietic stem cell sources: bone marrow, peripheral blood and cord blood.

PURPOSE: Dental CT software program can provide reformatted cross-sectional and panoramic images that cannot be obtained with conventional axial & direct coronal CT scan. The purpose of this study is to describe the method of the technique and to identify the precise anatomy of jaw. MATERIALS AND METHODS:We evaluated 13 mandibles & 7 maxillae of 15 subjects without bony disease who were being considered for endosseous dental implants. Reformatted images obtained by the use of bone algorithm performed on GE HiSpeed Advantage CT scanner were retrospectively reviewed for detailed anatomy of RESULTS: Anatomy related to neurovascular bundle(mandibular foramen, inferior alveolar canal, mental foramen, canal for incisive artery, nutrient canal, lingual foramen and mylohyoid groove), muscular insertion(mylohyoid line, superior & inferior genial tubercle and digastric fossa) and other anatomy(submandibular fossa, sublingual fossa, contour of alveolar process, oblique line, retromolar fossa, temporal crest & retromolar triangle) were well delineated in mandible. In maxilla, anatomy related to neurovascular bundle(greater palatine foramen & groove, nasopalatine canal and incisive foramen) and other anatomy(alveolar process, maxillary sinus & nasal fossa) were also well delineated. CONCLUSION: Reformatted images using dental CT software program provided excellent delineation of the jaw anatomy. Therefore, dental CT noftware program can play an important role in the preoperative assessment of mandible and maxilla for dental implants and other surgical conditions.
