Osteoporosis, the typical metabolic bone disease of the elderly, is characterized by a reduction in bone mineral density (BMD) and increased fracture risk. Genetic and environmental factors are known to play a key role in bone metabolism, and diet is also considered to be one of the important factors. The purpose of the present study was to investigate the relationship among the factors affecting BMD, including stature, body weight, age, time period since onset of menopause, and biochemical markers of bone turnover in postmenopausal women. Seventy-eight postmenopausal women who visited health promotion center for health examinations volunteered to participate in this study and they were divided into two groups according to the time period since onset of menopause : women with a time period since onset of menopause of less than 5 years (Group 1) and women with a time period since onset of menopause of 5 years or more (Group 2). The demographic characteristics and dietary intake were surveyed using a questionnaire. BMDs of the lumbar spine and femoral neck of subjects were measured by dual energy X-ray absorptiometry. Serum levels of 25-hydroxy-vitamin D and parathyroid hormone (PTH), known to be indicators of bone related hormone status, were anlyzed. Serum samples were measured for calcium, phosphorus, alkaline phosphatase, and osteocalcin as bone formation indicators, and urine was analysed for deoxypyridinoline, creatinine, calcium, and sodium as bone resorption indicators. The results are as follow : The mean BMDs of the lumbar spin and femoral neck were 1.02+/-0.02 g/cm2 and 0.81 +/-0.02 g/cm2, respectively, and the BMD level of Group 2 was significantly lower than tat of Group 1 (p<0.01, p<0.05, respectively). The mean daily intake of energy was 1838 +/- 55 kcal. When nutrient intake was compared with the recommended dietary allowances (RDA) of the subjects, only calcium, vitamin A and riboflavin intake showed means lower than the RDA. The nutrient intake did not show any significant differences between Group 1 and 2 Serum and urine levels of biochemical markers of bone turnover did not show any significant differences between Group 1 and 2, and all were within the normal range. However, the PTH and deoxypyridinoline levels showed a tendency to be higher, and the osteocalcin level to be lower in Group 2 than in Group 1. Although age and years after menopause (YAM) showed negative correlations with lumbar spine bone mineral density (LBMD) (r= -0.38, p<0.001, and r= -0.26, p<0.05, respectively), no correlation was found with femoral neck bone mineral density (NBMD). While height, body weight and body mass index (BMI) showed a positive correlation with LBMD (r= 0.32, p<0.001, r= 0.38, p<0.001, r= 0.22, p= 0.05, respectively), only body weight and BMI showed a positive correlation with NBMD (r= 0.30, p<0.01, and r= 0.27, p<0.05, respectivley). There was no significant corealtion between BMDs and the nutrient intake of subjects, except in the case of carbohydrates (r= 0.22, p<0.05). Also, serum and urine levels of bone turnover markers showed no significant correlation with nutrient intake. On the other hand, serum osteocalcin had a positive correlation with vitamin C intake (r= 0.22, p= 0.05), and urine deoxypyridinolin showed a negative correlation with niacin intake (r= -0.22, p= 0.05). Urinary na was negatively correlated with protein intake(r= -0.23, p= 0.05). The results suggested that it is difficult to prevent the decrease in bone mass among postmenopausal women eating the usual Korean diet. However, the BMDs of the lumbar spine and femoral neck were positively related to body weight ad BMI in postmenopausal women. Therefore, this study confirmed that one of the most effective ways to minimize bone loss in postmenopausal women would be to maintain an adequate body weight with balanced nutrient intake and activity in the pre-and postmenopausal periods.

This study was conducted to investigate dietary and other factors affecting bone mineral density (BMD) in Korean premenopausal women. Seventy-eight premenopausal women who visited the Health Promotion Center for health examinations volunteered to participate in this study. They were divided into two groups according to their bone status as shown by their T-scores: a non-osteoporotic group and a osteoporotic group. The results are as follows: The mean BMDs of the lumbar spine and femoral neck were 1.21 +/- 0.02 g/cm2 and 0.97 +/- 0.04 g/cm2, respectively. The BMD levels of the osteoporotic group were significantly lower than those of the non-osteoporotic group (p < 0.001, respectively). The heights of the women in the osteoporotic group were significantly lower than those of the non-osteoporotic group (p < 0.01) however, their body weights did not show any significant differences although they tended to be lower. The mean daily intake of energy was 1720 +/- 52 kcal. When the nutrient intake was compared with the Korean recommended dietary allowances (RDA), calcium, Fe, vitamin A and riboflavin intakes were lower than the RDA. Their was no significant difference in the nutrient intake of the non-osteoporotic group and osteoporotic group except for the intakes of protein, fat and niacin. Their was no significant difference between the non-osteoporotic group and the osteoporotic group and all were within the normal range. However, the serum alkaline phosphatase level of the osteoporotic group was significantly higher than that of the non-osteoporotic group (p < 0.001). Height measurements showed positive correlations with lumbar spine bone mineral density (LBMD, r = 0.332, p < 0.01) however there was no correlation with femoral neck bone mineral density (NBMD). Age, age at menarche, body weight, body mass index (BMI) and obesity showed no correlation with BMD. The BMD of the lumbar spine was significantly and positively related to the intake of niacin and vitamin C (r = 0.236, p < 0.05; r = 0.274, p < 0.05). Serum levels of calcium and phosphorus showed negative correlations with LBMD (r = -0.698, p = 0.0001; r = -0.503, p = 0.0001, respectively). The results suggested that the BMD of the lumbar spine was positively related to the intake of niacin and vitamin C in premenopausal women. Therefore, this study confirmed that one of the most effective ways to minimize bone loss would be have a higher intake of niacin and vitamin C rich foods and engaging habitually in physical activity may have a beneficial effect on BMD in the premenopausal period.

Carcinoma of Gall bladder remains a terminal illness in most patients despite improved diagnostic capabilities, better perioperative care and a more aggresive surgical approch based on improved knowledge of this tumors natural histiory. Overall 5-year survival rates remain below 5%. This failure to significantly improve patient oucome is largely due to late recognition of gall badder cancer. Authors experienced 21 cases of gall bladder cancer confirmed by operation at the Kwang Ju Christian hospital from march 1983 to March 1991, and the results obtained were summarized as follows.

Since the Korean College of Helicobacter and Upper Gastrointestinal Research has first developed the guideline for the diagnosis and treatment of Helicobacter pylori infection in 1998, the revised guideline was proposed in 2009 by the same group. Although the revised guideline was made by comprehensive review of previous articles and consensus of authoritative expert opinions, the evidence-based developmental process was not applied in the revision of the guideline. This new guideline has been revised especially in terms of changes in the indication and treatment of H. pylori infection in Korea, and developed by the adaptation process as evidence-based method; 6 guidelines were retrieved by systematic review and the Appraisal of Guidelines for Research and Evaluation (AGREE) II process, 21 statements were made with grading system and revised by modified Delphi method. After revision, 11 statements for the indication of test and treatment, 4 statements for the diagnosis and 4 statements for the treatment have been developed, respectively. The revised guideline has been reviewed by external experts before the official endorsement, and will be disseminated for usual clinical practice in Korea. Also, the scheduled update and revision of the guideline will be made periodically.

PURPOSE: Computed radiography (CR) has been used in cephalometric radiography and many studies have been carried out to improve image quality using various digital enhancement and filtering techniques. During CR image acquisition, the frequency rank and type affect to the image quality. The aim of this study was to compare the diagnostic quality of conventional cephalometric radiographs to those of computed radiography. MATERIALS AND METHODS: The diagnostic quality of conventional cephalometric radiographs (M0) and their digital image counterparts were compared, and at the same time, six modalities (M1-M6) of spatial frequency-processed digital images were compared by evaluating the reproducibility of 23 cephalometric landmark locations. Reproducibility was defined as an observer's deviation (in mm) from the mean between all observers. RESULTS AND CONCLUSION: In comparison with the conventional cephalometric radiograph (M0), M1 showed statistically significant differences in 8 locations, M2 in 9, M3 12, M4 in 7, M5 in 12, and M6 showed significant differences in 14 of 23 landmark locations (p<0.05). The number of reproducible landmarks that each modality possesses were 7 in M6, 6 in M5, 5 in M3, 4 in M4, 3 in M2, 2 in M1, and 1 location in M0. The image modality that observers selected as having the best image quality was M5.

BACKGROUND/AIMS: DA-6034 has anti-inflammatory activities and exhibits cytoprotective effects in acute gastric injury models. However, explanations for the protective effects of DA-6034 on intestinal permeability are limited. This study sought to investigate the effect of DA-6034 on intestinal permeability in an indomethacin-induced small intestinal injury model and its protective effect against small intestinal injury. METHODS: Rats in the treatment group received DA-6034 from days 0 to 2 and indomethacin from days 1 to 2. Rats in the control group received indomethacin from days 1 to 2. On the fourth day, the small intestines were examined to compare the severity of inflammation. Intestinal permeability was evaluated by using fluorescein isothiocyanate-labeled dextran. Western blotting was performed to confirm the association between DA-6034 and the extracellular signal-regulated kinase (ERK) pathway. RESULTS: The inflammation scores in the treatment group were lower than those in the control group, but the difference was statistically insignificant. Hemorrhagic lesions in the treatment group were broader than those in the control group, but the difference was statistically insignificant. Intestinal permeability was lower in the treatment group than in the control group. DA-6034 enhanced extracellular signal-regulated kinase expression, and intestinal permeability was negatively correlated with ERK expression. CONCLUSIONS: DA-6034 may decrease intestinal permeability in an indomethacin-induced intestinal injury model via the ERK pathway.

BACKGROUND: The bone graft for the alveolar cleft has been accepted as one of the essential treatments for cleft lip patients. Precise preoperative measurement of the architecture and size of the bone defect in alveolar cleft has been considered helpful for increasing the success rate of bone grafting because those features may vary with the cleft type. Recently, some studies have reported on the usefulness of three-dimensional (3D) computed tomography (CT) assessment of alveolar bone defect; however, no study on the possible implication of the cleft type on the difference between the presumed and actual value has been conducted yet. We aimed to evaluate the clinical predictability of such measurement using 3D CT assessment according to the cleft type. METHODS: The study consisted of 47 pediatric patients. The subjects were divided according to the cleft type. CT was performed before the graft operation and assessed using image analysis software. The statistical significance of the difference between the preoperative estimation and intraoperative measurement was analyzed. RESULTS: The difference between the preoperative and intraoperative values were -0.1+/-0.3 cm3 (P=0.084). There was no significant intergroup difference, but the groups with a cleft palate showed a significant difference of -0.2+/-0.3 cm3 (P<0.05). CONCLUSIONS: Assessment of the alveolar cleft volume using 3D CT scan data and image analysis software can help in selecting the optimal graft procedure and extracting the correct volume of cancellous bone for grafting. Considering the cleft type, it would be helpful to extract an additional volume of 0.2 cm3 in the presence of a cleft palate.

PURPOSE: Oncogenes, tumor suppressor genes, and growth variables of tumors are important in the assessment of prognosis in lung cancer. The expression of PCNA, c-erbB-2 (HER-2/neu), and c-fos oncoprotein and their prognostic implications in surgically resected patients with non-small cell lung cancer were evaluated. MATERIALS AND METHODS: Seventy patients with non-small cell lung cancer were included and PCNA, c-erbB-2 and c-fos overexpression were evaluated by immunohistochemical stain using paraffin-embedded tissue. RESULTS: The mean proportion of PCNA positive cells was 18.6%, and there was no significant difference according to cell type and stage. The median survival time was significantly shorter in the group with high PCNA expression (>10%) as compared with the group with low PCNA expression (<10%) (37 months vs 16 months). Four (6.3%) of 64 cases demonstrated c-erbB-2 positivity. These were all adenocarcinoma cases. c-fos protein was only rarely overexpressed (1/51). CONCLUSION: PCNA expression was shown to be a useful prognostic parameter in resected non-small cell lung cancer while c-erbB-2 and c-fos oncoprotein were infrequently expressed.
