PURPOSE: The purpose was to investigate the factors influencing alcohol consuming behavior of the female university students to provide the basic data for a nursing intervention program to improve health and prohibit of alcohol consuming behavior. METHOD: The subjects were 134 female university students, studying at K university and K educational university in Chungnam province from April 1 to 20, 2002. The instruments were the alcohol consuming behavior scale, that is drinking intensity score, and alcohol problem developed by Shin(1998), refusal self-efficacy scale by Aas et. al.(1995), alcohol expectancy by Goldman at. al.(1989), TPQ scale by Cloninger(1991), depression scale modified by Shin(1977) using Zung(1965)' tool, family cohesion scale by Olson at. al.(1983). The data were analyzed using descriptive statistics, Pearson correlation coefficient, canonical correlation and stepwise multiple regression. RESULT: The most powerful predictor of alcohol consuming behavior was influence of friends-drinking(21.0%). A combination of economic status(8.0%), and personality of novelty seeking(3.0%), accounted for 32.0% of the variance in alcohol consuming behavior. CONCLUSION: I recommended that economic status, influence of friends drinking frequently, and personality of novelty seeking were contained of the developing nursing intervention program for decreasing the alcohol consuming behavior in female university students.

It is well known that malnutrition is a predictor of mortality in hemodialysis patients. The number of diabetic nephropathy patients is increasing rapidly. This study aimed to investigate nutritional status and nutrient intake according to the presence of diabetes among hemodialysis patients. The nutritional intake and general characteristics of outpatients at Ajou University Hospital (24 with diabetes and 30 without diabetes) were investigated between July and September 2015. Patients' general data were collected, and nutritional status by Patient-Generated Subjective Global Assessment (PG-SGA) was evaluated. Nutrient intakes were assessed according to 3-day food records. There was no significant difference regarding body weight between the two groups. However, the non-diabetic group showed a better nutritional status by Patient-Generated Subjective Global Assessment (PG-SGA) (5.2±4.4 vs. 8.0±4.3 score, non-diabetics vs. diabetics, P<0.05). There was no difference in daily calorie intake (1,473.9±370.5 vs. 1,503.8±397.5 kcal) and protein intake (60.3±19.7 vs. 65.6±20.5 g) in those with diabetes. Intakes of vegetables protein, sodium, potassium, vitamin C, folic acid and fiber were significantly higher in the diabetic group compared to those of the non-diabetic group. There was no difference in daily nutrient intake between the hemodialysis weekday and weekend groups. The non-diabetic group had higher calorie and sodium intakes per meal in the hemodialysis weekday group, but the difference was not significant. Based on these results, intervention should be performed to improve nutritional status in consideration of diabetes and dietary patterns.

PURPOSE: Accurate clinical diagnosis of acute appendicitis is more difficult in children since they may not be able to communicate their complaints adequately, and findings on physical examination may be nonspecific.The uncertainty in diagnosis may lead to a delay of surgery or to unnecessary laparotomy. Prompt diagnosis is important due to their complications such as perforation, abscess formation, and peritonitis. The authors conducted this study in order to find out usefulness of ultrasonography in diagnosis of acute appendicitis in children. METHODS: The authors was performed ultrasonographical examination to 290 children with abdominal pain under the age of 15 during a recent 16-months period from January 1994 to April 1995. High-resolution ultrasonography was used according to the graded compression method. The ultrasonographic findings were correlated with pathologic outcome in 87 cases. RESULTS: 1) Among 290 patients with abdominal pain, acute appendicitis was 81 cases (27.9%), and there were mesenteric lymphadenitis, terminal ileitis, intussusception, acute gastroenteritis, and nonspecific findings. 2) Sex ratio of acute appendicitis was 1.53:1. The acute appendicitis was occurred 13.6% in under the age of 5 and 86.4% in over the age of 6. Mean age was 10.6 3) The most frequent symptom was abdominal pain followed by vomiting, fever, nausea, and diarrhea. 4) Leukocytosis (>10,000/cu.mm) was occurred in 71 of 81 (87.7%) cases of acute appendicitis and 24 of 28 (85.7%) cases of acute appendicitis with perforation. 5) The perforation rate was higher in delayed diagnosis and in younger children. 6) Ultrasonography had a sensitivity of 97.5%, specificity of 96.2%, positive predictive value of 90.8%, and negative predictive value of 99.0% on diagnosis in acute appendicitis. CONCLUSIONS: Upon the above results, the authors were able to conclude that graded compression ultrasonography had high sensitivity and specificity and was useful for the diagnosis of acute appendicitis in children. And the ultrasonography can be applied as rapid, noninvasive, and well-tolerated investigation. So, it has diagnostic value as screening test in children whose chief complaint is abdominal pain.

OBJECTIVE: To compare the diagnostic performance of digital breast tomosynthesis (DBT) and conventional breast ultrasound (US) to characterize breast lesions as benign or malignant. MATERIALS AND METHODS: A total of 332 women, presenting for screening examinations or for breast biopsy between March and June 2012 were recruited to undergo digital mammography (DM), DBT, and breast US examination. Among them, 113 patients with 119 breast lesions depicted on DM were finally included. Three blinded radiologists performed an enriched reader study and reviewed the DBT and US images. Each reader analyzed the lesions in random order, assigned Breast Imaging Reporting and Data System (BI-RADS) descriptors, rated the images for the likelihood of malignancy (%) and made a BI-RADS final assessment. Diagnostic accuracy, as assessed by the area under the receiver operating characteristic curve, sensitivity, and specificity of DBT and US were compared. RESULTS: Among the 119 breast lesions depicted on DM, 75 were malignant and the remaining 44 were benign. The average diagnostic performance for characterizing breast lesions as benign or malignant in terms of area under the curve was 0.899 for DBT and 0.914 for US (p = 0.394). Mean sensitivity (97.3% vs. 98.7%, p = 0.508) and specificity (44.7% vs. 39.4%, p = 0.360) were also not significantly different. CONCLUSION: Digital breast tomosynthesis may provide similar reader lesion characterization performance to that of US for breast lesions depicted on DM.

OBJECTIVE: Our purpose was to investigate urinary malondialdehyde (MDA), manganese superoxide dismutase (Mn-SOD) activity and polymorphism in placental tissues of women with preeclampsia and to evaluate oxidative stress in the pathophysiology of preeclampsia. METHODS: Urins and placental tissues were obtained from 20 normal and 20 preeclamptic women at 3rd trimester. Urinary MDA was assayed by an high performanance liquid chromatography (HPLC). The placental Mn-SOD activity was assayed by westen blotting and The placental Mn-SOD genotyping was assayed by PCR-RFLP. Data were analyzed statistically using Student's t-test and Chi-square test. RESULTS: 1) Urinary concentration of MDA was not significantly different in preeclampsia (4.43+/-2.37 ug/g) as compared with normotensive pregnancy (4.39+/-1.17 ug/g). 2) Preeclamptic women had similar Mn-SOD activity in placenta (1.04+/-0.04U/mL protein) as compared with normotensive pregnancy (1.44+/-0.34 U/mL protein). 3) No significant difference in the polymorphismthe of Mn-SOD genotype in placenta was observed between preeclampsia and normotensive pregnancy (X2=0.06, p>0.05) CONCLUSION: The findings in this study do not show that oxidative stress might be a pathogenetically relevent process causally contributing to the disease, and polymorphism in the Mn-SOD genotype in placenta do not seem to be risk factors for preeclampsia.

OBJECTIVE: To identify prenatal fetal sex and chromosomal aneuploidies by FISH using isolation of fetal nucleated RBCs. METHODS: peripheral blood samples was collected from 37 women between 11 and 24 weeks of gestation. we tried to enrich nucleated RBCs morphologically by Kleihaur-Betke staining after double gradient centrifugation and magnetic activating cell sorting (MACS) from maternal blood. Fluorescence in situ hybridization (FISH) analyses with CEP X and CEP Y probes for K-B positive nucleated RBCs were performed to detect whether fetal cells were existed among nucleated RBCs by observation of sex chromosomes. RESULTS: The average number of K-B positive nucleated RBCs separated from 10ml of maternal blood was 17.3 (+/-17.2) and the maximum number of nucleated RBCs was 54. We observed FISH signals in nucleated RBCs separated from 18 pregnant women, and Y probe signals were observed in 67.3% of nucleated RBCs separated from 10 pregnant women. CONCLUSION: We confirmed that separated nucleated fetal RBCs can be used to identify fetal sex and chromosomal aneuploidies by FISH. Since nucleated RBCs from maternal origin were not excluded, further studies are needed to overcome this limitation.

P7C3 and its derivatives, 1-(3,6-dibromo-9H-carbazol-9-yl)-3-(p-tolylamino)propan-2-ol (1) and N-(3-(3,6-dibromo-9H-carbazol-9-yl)-2-hydroxypropyl)-N-(3-methoxyphenyl)-4-methylbenzenesulfonamide (2), were previously reported to increase neurogenesis in rat neural stem cells (NSCs). Although P7C3 is known to increase neurogenesis by protecting newborn neurons, it is not known whether its derivatives also have protective effects to increase neurogenesis. In the current study, we examined how 1 induces neurogenesis. The treatment of 1 in NSCs increased numbers of cells in the absence of epidermal growth factor (EGF) and fibroblast growth factor 2 (FGF2), while not affecting those in the presence of growth factors. Compound 1 did not induce astrocytogenesis during NSC differentiation. 5-Bromo-2\'-deoxyuridine (BrdU) pulsing experiments showed that 1 significantly enhanced BrdU-positive neurons. Taken together, our data suggest that 1 promotes neurogenesis by the induction of final cell division during NSC differentiation.

OBJECTIVE: The purpose of this study is to assess the relationship between the oligohydramnios and umbilical venous blood EPO levels and nRBC counts, and to investigate the significance of oligohydramnios as intrauterine hypoxic marker in AGA and SGA fetuses. METHODS: EPO and nRBC were measured in 217 singletons with a gestational age of 32 to 42 weeks at delivery. The subjects were divided into 4 groups: group 1 (AGA with normal amniotic fluid volume, n=129), group 2 (AGA with oligohydramnios, n=15), group 3 (SGA with normal amniotic fluid volume, n=57) and group 4 (SGA with oligohydramnios, n=11). EPO levels and nRBC counts in group 2, 3 and 4 were compared to those in group 1 using Mann-Whitney U-test. Relationship between EPO and nRBC was assessed using linear regression analysis. In addition, relationship between results of umbilical venous blood gas analysis and EPO/nRBC was assessed using the same method. P-values less than 0.05 were considered statistically significant. RESULTS: EPO levels and nRBC counts in AGA with oligohydramnios (group 2) were not significantly different from those in AGA with normal amniotic fluid volume (group 1). EPO levels in SGA with normal amniotic fluid volume (group 3) were significantly higher than those in AGA with normal amniotic fluid volume (group 1). EPO levels and nRBC counts in SGA with oligohydramnios (group 4) were significantly higher than those in AGA with normal amniotic fluid volume (group 1). There was significant positive correlation between EPO and nRBC. Parameters obtained from the umbilical venous blood gas analysis were more related with nRBC than EPO. CONCLUSION: Oligohydramnios was significant intrauterine hypoxic marker in SGA fetuses. However, the results of this study suggested that the influence of oligohydramnios on antenatal fetal condition might be less severe in AGA fetuses than in SGA fetuses. Moreover, it was likely that nRBC had stronger association with pathologic hypoxia than EPO did.

Overtube provides a conduit for the passage of endoscope into the digestive tract. Esophageal perforation with mediastinitis is a rare overtube-related complication. Until now, no reports have been published regarding the esophageal perforation which developed many months after the original procedure using the overtube. A 56-year-old female visited our hospital complaining of chest pain and back pain that began 14 days ago. The patient underwent esophageal variceal ligation using the overtube 12 months earlier. She was diagnosed with esophageal perforation with mediastinitis which extended to intervertebral and epidural space. The cause of this condition was considered to have been related to the use of overtube. Management of delayed perforation remains controversial. Although surgical management might be the preferred mode of treatment, she underwent local N-butyl 2-cyanoacrylate injection therapy and temporary stent therapy with antibiotics due to high operative risk. Herein, we report a case of overtube-related delayed esophageal perforation with mediastinitis that was successfully treated by nonoperative management.
