BACKGROUND/OBJECTIVES: College students are in transition from adolescence to adulthood, and it has been reported that they show poor dietary habits. This study was conducted to compare body image perception, nutrition knowledge, dietary attitudes, dietary habits, and health-related lifestyles between Korean college students (KCS) and Mongolian college students (MCS). SUBJECTS/METHODS: Subjects were 314 KCS and 280 MCS. The data includes results of self-administered questionnaires; statistical analysis was performed using the SPSS 23.0 program. RESULTS: With regards to body image perception, KCS perceived themselves to be fatter on current body image than ideal body image compared to MCS; 64.0% of KCS and 34.6% of MCS desired to be thinner. Total score of nutrition knowledge in KCS (17.0) was significantly higher compared to MCS (8.4) (P < 0.001), but total score of dietary attitudes in KCS (27.0) was significantly lower compared to MCS (31.2) (P < 0.001). Nutrition knowledge had a significantly positive correlation with dietary attitudes in MCS (P < 0.01). Meal consumption among male and female subjects was 2 and 3 times, respectively, in order in KCS, and 3 and 2 times, respectively, in order in MCS (P < 0.001). Rate of skipping breakfast in both genders was significantly higher in KCS than in MCS (male: P < 0.05, female: P < 0.001). In health-related lifestyles, KCS had a significantly higher rate in frequency of alcohol drinking (P < 0.001), exercise (P < 0.01), and mobile phone usage (P < 0.001), compared to MCS. CONCLUSIONS: This study suggests that development of nutrition education program which is effective and proper is required to improve healthy dietary habits among college students of both countries. Essential contents should include acquirement of nutrition knowledge and a motivation for its application to actual life for KCS, and improvement of healthy dietary habits for MCS.

This research is to estimate the toxicity of Atractylodis Rhizoma Alba (ARA) in F344 rats and to find a dose level for the 13 weeks toxicity study. A hot water extract of ARA (ARWE) was administered orally to F344 rats at dose levels of 0 (vehicle control), 500, 1000, 2000, 3500, and 5000 mg/kg/day for 2 weeks. Each group was composed to five male and five female F344 rats. According to the result, there were no ARWE-related adverse changes in mortality, body weights, food consumption, urinalysis, hematology, clinical chemistry, gross finding at necropsy, and organ weight examination. Salivation was observed in 3500 and 5000 mg/kg/day in male and female rats but it could not have found any relationship with ARWE administration. Based on our findings, ARWE may not cause toxicity in rats under the experimental conditions. Therefore, dose level of 5000 mg/kg/day as a highest treatment group in 13-week exposure study is recommended for further toxicity assessment.

The objective of this study is to characterize a toxicity of Epimedii Herba (EH) in F344 rats and to find a dose levels for the 13 weeks toxicity study. EH is well known as medicinal herb in many Asian countries for traditional medicines of antibacterial and antiviral effects, estrogenic and antiestrogenic effects, and for treatment of osteoporosis, hypotensives, fatigue, kidney disorders, and related complications. However, the indispensable and basic information of toxicological evaluation of EH extract is insufficient to support its safe use. Therefore, we conducted toxicological evaluation of this drug in compliance with OECD and MFDS guideline in this study. The extract of EH was administered orally to F344 rats at dose levels of 0, 500, 1000, 2000, 3500, and 5000 mg/kg/day for 2 weeks. Each group was composed of 5 male and female rats. In this study, there were no treatment of EH-related adverse changes in clinical observations, mortality, body weights, food consumption, urinalysis, gross finding at necropsy, and organ weight examination. Total red blood cell count, hematocrit, mean corpuscular hemoglobin concentration, total cholesterol, and phospholipid were decreased in males and females at 5000 mg/kg/day compared to the control animals. Mean corpuscular volume and reticulocyte counts were increased in males and females at 5000 mg/kg/day compared to control animals. Therefore, we recommend that dose level of 5000 mg/kg/day is a highest treatment group in 13-week EH extract exposure study for further toxicity assessment.

BACKGROUND: Restoring orbital volume in large blowout fractures is still a technically challenge to the orbital surgeon. In this study, we restored the orbital wall using the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses, and we compared the surgical outcome to that of a conventional transorbital method. METHODS: A retrospective review of all patients with pure unilateral blowout fractures between March 2007 and March 2013 was conducted. 150 patients were classified into two groups according to the surgical method: conventional transorbital method (group A, 75 patients, control group), and the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses (group B, 75 patients, experimental group). Each group was subdivided depending on fracture location: group I (inferior wall), group IM (inferomedial wall), and group M (medial wall). The surgical results were assessed by the Hertel scale and a comparison of preoperative and postoperative orbital volume ratio (OVR) values. RESULTS: In the volumetric analysis, the OVR decreased more by the experimental groups than each corresponding control groups (P<0.05). Upon ophthalmic examination, neither the differences among the groups in the perioperative Hertel scale nor the preoperative and postoperative Hertel scales were statistically significant (P>0.05). CONCLUSIONS: Our surgical results suggest that orbital volume was more effectively restored by the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses than the conventional method, regardless of the type of fracture.

This study was conducted to evaluate the effects of a body weight control program with supplementation of sea tangle (20 g/day) on 22 female college students. The contents of the program for 8 weeks contained diet therapy, exercise and behavioral modification through nutrition education. Body composition, dietary habit scores, serum lipid profiles, daily nutrient intakes and the quality of life were assessed at the beginning and at the end of the program. Average age of subjects and height were 20.8 years and 161.9 cm, respectively. After 8 weeks, there were significant reductions in body weight, body fat mass, percent body fat, waist-hip ratio and BMI. The dietary habit score such as a balanced diet, regularity of mealtime, overeating, eating while watching TV or using the computer and eating salty food were increased significantly. Serum lipid levels such as total cholesterol level, LDL-cholesterol level and triglyceride level were decreased but not significantly. There were decreases in intake of energy, protein and fat and increases in intakes of dietary fiber, folic acid, calcium and potassium from the beginning to the end of the program. There were significant improvements on subcomponents of quality of life; physical functioning, general-health and vitality. The limitation of this study was the fact that there was no control group, but an overall evaluation suggests the 8-week body weight control program consisting of diet therapy, exercise and behavioral modification with supplementation of sea tangle would be helpful to improve the body composition, dietary habits, daily nutrient intakes and quality of life in Korean female college students.

Claudin-7 has recently been suggested to be a distal nephron marker. We tested the possibility that expression of claudin-7 could be used as a marker of renal tumors originating from the distal nephron. We examined the immunohistochemical expression of claudin-7 and parvalbumin in 239 renal tumors, including 179 clear cell renal cell carcinoma (RCC)s, 29 papillary RCCs, 20 chromophobe RCCs, and 11 renal oncocytomas. In addition, the methylation specific-PCR (MSP) of claudin-7 was performed. Claudin-7 and parvalbumin immunostains were positive in 3.4%, 7.8% of clear cell RCCs, 34.5%, 31.0% of papillary RCCs, 95.0%, 80.0% of chromophobe RCCs, and 72.7%, 81.8% of renal oncocytomas, respectively. The sensitivity and specificity of claudin-7 in diagnosing chromophobe RCC among subtypes of RCC were 95.0% and 92.3%. Those of parvalbumin were 80.0% and 88.9%. The expression pattern of claudin-7 was mostly diffuse in chromophobe RCC and was either focal or diffuse in oncocytoma. All of the cases examined in the MSP revealed the presence of unmethylated promoter of claudin-7 without regard to claudin-7 immunoreactivity. Hypermethylation of the promoter might not be the underlying mechanism for loss of its expression in RCC. Claudin-7 can be used as a useful diagnostic marker in diagnosing chromophobe RCC and oncocytoma.

PURPOSE: This study was done to identify fat distribution and blood pressure according to anthropometric change patterns between NIDDM patients and control subjects. METHODS: Cross-sectionally 167 NIDDM patients and 87 controls were studied. Previous maximal body weight and acute weight loss was obtained. Current height, body weight, BMI, waist-hip ratio(WHR), skinfold thicknesses(abdomen, subscapular and triceps), and blood pressure was measured. Three anthropometric change patterns were categorized by BMI changes from the maximum lifetim's BMI to the current time (obese-obese, obese-nonobese and nonobese-nonobese: obese: BMI > or =25 kg/m2, nonobese: BMI<25 kg/m2). The data was analyzed by chi-square, t-test, age adjusted ANCOVA and Least Squares Means(LSM) for multiple comparison. RESULT: Acute body weight loss(p=0.01), anthropometric change types (p=0.001), WHR (P=0.05), and skinfold thickness (p=0.002) of NIDDM were significantly higher than those of the controls. The mean arterial pressure, WHR and skinfold thicknesses were greater in both obese-obese and obese-nonobese NIDDM and control subjects compared with both nonobese-nonobese NIDDM and control subjects. (all p's<0.05). CONCLUSION: NIDDM patients had more central and upper body adiposicity. Also both obese-obese and obese-nonobese NIDDM and control subjects had higher mean arterial pressures and central body obesity.

PURPOSE: The purpose of this study was to compare the effects of oral hygiene with 0.1% chlorhexidine or with normal saline on the incidence of pathogens in the oral cavity of patients in Intensive Care Units (ICU). METHOD: A quasi experimental design with non-equivalent control group and non-synchronized design was used. For the study 46 patients were recruited from a university hospital (24 for the experimental group, 22 for the control group). patients in the experimental group received mouth care with 0.1% chlorhexidine gluconate and those in the control group received mouth care with normal saline twice a day for 7 days in a row. Oral samples were taken for bacterial cultures on admission day, the 4th day and the 7th day for both groups. RESULTS: The incidence of oral pathogens decreased in the experimental group, and increased in the control group. There was no significant difference in the incidence of oral pathogens between the two groups. However oral hygiene using 0.1% chlorhexidine gluconate decreased the incidence of oral pathogens significantly for patients who already had pathogenic bacteria in their mouths on the admission day. CONCLUSION: The results suggest that mouth care with 0.1% chlorhexidine is effective for decreasing the incidence of oral infection for ICU patients who have oral infections.

PURPOSE: This correlation study was undertaken to examine the relationships between daily life stress, self-efficacy and university student life adjustment and to analyze the self-efficacy affecting that university student life adjustment. METHODS: 265 university students were recruited from several participating required undergraduate classes. They were surveyed as the subject of this study. Data collection was conducted through the use of questionnaires. RESULTS: The university life adjustment level showed a maximum score of 9 with the mean score 5.22. A negative correlation was found between daily life stress and university life adjustment. Also, there was positively correlation between self-efficacy and university life adjustment. Self-efficacy and daily life stress accounted for 23% of the variance in university student life adjustment. CONCLUSION: According to the results, self-efficacy is a useful concept in helping overall university life adjustment. Therefore, university student consultation office or nurse should consider the program based on selfefficacy in order to help university students to better adapt to university life.

In treating women with leiomyoma and who wish to preserve their uterus, laparoscopic uterine artery ligation or uterine artery embolization should be considered as possible options. This study was performed to evaluate the efficacy of laparoscopic uterine artery ligation and uterine artery embolization in treating uterine myoma. The treatment outcomes of 23 patients who underwent uterine artery embolization and 17 laparoscopic uterine artery ligation were evaluated. The uterine volume reduced 3 months after uterine artery embolization, but thereafter no significant changes were observed. On the other hand, the uterine volumes were only slightly reduced 3 months after laparoscopic uterine artery ligation, and slightly more reduced 6 months later. The average reduction in the case of laparoscopic uterine artery ligation was about 58.5%. After laparoscopic uterine artery ligation, 20% of the patients complained of vaginal spotting. Furthermore, the mechanism of volume reduction was evaluated using specimens obtained from a biopsy taken after each procedure. The results suggested that laparoscopic uterine artery ligation results mainly in physiologic cell death, that is apoptosis, whereas, the corresponding result is cell necrosis for uterine artery embolization. Uterine artery embolization and laparoscopic uterine artery ligation are both effective in relieving the symptoms caused by uterine myoma, and therefore both procedures can be used in place of hysterectomy or myomectomy.
