This study was carried out to investigate the perception of body image, the dietary attitude, the nutrient intake and the dietary self-efficacy of middle school students in Kyoung-Nam. The survey was conducted from April 8 to April 22 in 2002. The results are summarized as follows. Twenty three point nine percents of the underweight group, 24.5% of the normal weight group, 57.1% of the overweight group and 62.5% of the obese group had correct perception about their body image. Most of the students were concerned about their body image and weight control. The obesity of the parents correlated significantly with the obesity of the subjects. The higher the obesity rate, the lower the dietary attitude and dietary self-efficacy. There was a significant positive correlation between the education level of their mothers and the dietary attitude of the subjects and a significant negative correlation between the obesity rate of the subjects and their dietary attitudes. Dietary attitude scores showed no significant difference among the groups. Intakes of calories, protein, calcium and iron were lower than those of the Korean recommended dietary allowances (RDAs).

OBJECTIVE: The purpose of our study was to investigate the effect of the mode of delivery on the oxidant and antioxidant system in umbilical cord blood. METHODS: We performed gas analysis of umbilical venous blood and umbilical arterial blood immediately after delivery in 38 women; eighteen women had a vaginal delivery while 20 women delivered via cesarean section at over 37 weeks gestation. We examined lipid peroxide concentration by thiobarbituric acid reaction, protein carbonyl content by 2,4-dinitrophenylhydrazine reaction, and total antioxidant capacity by oxygen radical absorbance capacity assay. RESULTS: Lipid peroxide levels in umbilical venous blood were significantly higher in patients delivering by planned cesarean section (1.81 +/- 0.06 nmol/mg protein) than those with vaginal delivery (1.24 +/- 0.05 nmol/mg protein) (P < 0.05). Antioxidant capacity in umbilical venous blood was significantly higher in patients delivering by planned cesarean section (119.70 +/- 0.13 microM/microL) than those with a vaginal delivery (118.70 +/- 0.29 microM/microL) (P < 0.05). There was no significant difference in the carbonyl content of umbilical venous blood or in the lipid peroxide, carbonyl content, and total antioxidant capacity of umbilical arterial blood. CONCLUSION: Lipid peroxidation levels and antioxidant capacity in umbilical venous blood were higher in patients delivering by planned cesarean section than those with a vaginal delivery. Therefore, we propose that both the mother and neonate are exposed to higher oxidative stress during cesarean section delivery.

PURPOSE: Food protein-induced enterocolitis syndrome (FPIES) is a symptom complex of vomiting and diarrhea caused by non-IgE mediated allergy to cow's milk and/or soy in young infants. Transforming growth factor (TGF)-beta has been reported to protect the epithelial barrier of the gut from foreign antigens. We studied the expression of type 1 and 2 TGF-beta receptors in the mucosa of small intestine to investigate their roles in the pathogenesis of FPIES. METHODS: Twenty-eight patients, aged 7 to 120 days (mean 49 days) who were diagnosed with FPIES by clinical criteria and challenge tests were included. Immunohistochemical stainings for type 1 and 2 TGF-beta receptors were performed on endoscopic duodenal biopsy specimens. RESULTS: Type 1 and 2 TGF-beta receptors were expressed in the villous and crypt epithelial cells but nearly absent in the lamina propria in both patients and controls. Type 1 TGF-beta receptor expression was significantly lower in the patients who had villous atrophy than in the patients who had not and in controls. The expression of type 1 TGF-beta receptor was negatively correlated with the severity of villous atrophy. Type 2 TGF-beta receptor expression showed no significant difference between the patients and controls. CONCLUSION: Our results suggests that the decreased activity of type 1 TGF-beta receptor is implicated in the pathogenesis of FPIES in young infants.

BACKGROUND: Micro computed tomography (CT) is rapidly developing as an imaging tool, especially for mice, which have become the experimental animal of choice for many pulmonary disease studies. We evaluated the usefulness of micro CT for evaluating lung fibrosis in the murine model of bleomycin-induced lung inflammation and fibrosis. METHODS: The control mice (n=10) were treated with saline. The murine model of lung fibrosis (n=60) was established by administering bleomycin intra-tracheally. Among the 70 mice, only 20 mice had successful imaging analyses. We analyzed the micro CT and pathological findings and examined the correlation between imaging scoring in micro CT and histological scoring of pulmonary inflammation or fibrosis. RESULTS: The control group showed normal findings on micro CT. The abnormal findings on micro CT performed at 3 weeks after the administration of bleomycin were ground-glass opacity (GGO) and consolidation. At 6 weeks after bleomycin administration, micro CT showed various patterns such as GGO, consolidation, bronchiectasis, small nodules, and reticular opacity. GGO (r=0.84) and consolidation (r=0.69) on micro CT were significantly correlated with histological scoring that reflected pulmonary inflammation (p<0.05). In addition, bronchiectasis (r=0.63) and reticular opacity (r=0.83) on micro CT shown at 6 weeks after bleomycin administration correlated with histological scoring that reflected lung fibrosis (p<0.05). CONCLUSION: These results suggest that micro CT findings from a murine model of bleomycin-induced lung fibrosis reflect pathologic findings, and micro CT may be useful for predicting bleomycin-induced lung inflammation and fibrosis in mice.

PURPOSE: The purpose of this study was to provide direction to improvement of advanced cardiovascular life support (ACLS) training in Korea. METHODS: We conducted a retrospective analysis of the questionnaire written by 55 instructors of the 31 institutions registered in the Korean Association of Cardiopulmonary Resuscitation (KACPR) from 2009 and 2010. The contents of the questionnaire consisted of an evaluation of the ACLS curriculum, modification of the ACLS curriculum, problems of ACLS training, and other open-ended answers. RESULTS: In this questionnaire, the result for assessment of the lecture on acute coronary syndrome was intermediate, that answer was given by the majority, 40.0%. The result for assessment of the lecture on stroke was intermediate, that answer was given by the majority, 40.0%. In addition, the result for the necessity of the lecture on acute coronary syndrome was intermediate, 25.5%, which was the most common response. The result for the necessity of the lecture on stroke was intermediate, 27.3%, which was the most common response. In the ACLS curriculum, 14.5% of respondents responded that simulation curriculum should be strengthened; 20.0% of participants responded that training on equipment and medical technique should be enhanced. CONCLUSION: Lecture without practice should be avoided and simulation-oriented education should be strengthened in the ACLS course.

The terms chronic active hepatitis (CAH), chronic persistent hepatitis (CPH), and chronic lobular hepatitis (CLH) should be discontinued in favor of etiologic terminology. The activity of necro-inflammation and the degree of fibrosis should be evaluated for grading the severity and for the stage of disease. Members of the Korean Study Group for the Pathology of Digestive Diseases reviewed 30 cases of chronic hepatitis and reached the following consensus: 1) The pathology report of the biopsy samples with features of chronic hepatitis should include the etiology, grade and stage. 2) Grade and stage should be semiquantitatively evaluated as none, minimal, mild, moderate and severe. 3) For grading, lobular activity and periportal activity should be evaluated, separately. 4) To avoid confusion with other grading systems, simple report using descriptive terms rather than numerical records is recommended in daily practice. Criteria for each grade and stage should be presented and discussed. Histologic grading and staging of chronic hepatitis by new standardized guidelines will give more information about the prognosis as well as the present status of hepatitis. The terms CAH, CPH and CLH may be used in parentheses to facilitate relearning.

PURPOSE: As outdoor allergen, pollen and mold are increasely drawing attention all over the country in Korea. The peninsula is located in a temperate zone and has four distinct seasons. In this study, we described the seasonal variation of the pollen and mold distributions in Korea, which may be used to evaluate the pollenosis prevalence for the first time. METHODS: Rotorod samplers were installed on the 10 stations at each state in Korea. Outdoor allergens were collected daily in each station from July 1, 1997 to June 30, 1999. After staining they were identified, counted and recorded with the weather in each state. RESULTS: The pollens were found in the beginning of February through the middle of December. The earliest pollen was found from Pusan which is a south region, and followed by Chonju, Daegu which are midsouth. The peak season for pollen was from the end of April to the middle of May(major pollen: Tree, Grasses), the second peak was depicted from the end of August to the middle of September (major pollen : sagebrush, ragweed) the outdoor molds were largely collected from the July to the middle of October. Cladosporium and Alternaria were prevalent all year round and Ascospores of Leptospheria was peak in monsoon season. CONCLUSION: The pollens were found during the whole year except from middle of the December through the middle of the January. Molds were found all year round.
