Purpose: The current study was conducted in order to identify health and nutritional status of Korean underweight women in their twenties by comparing with normal, overweight, and obese women. Methods: Data from the 2010~2012 Korea National Health and Nutrition Examination Survey were used in this study. Subjects were 897 women aged 20~29 years. Subjects were classified according to underweight, normal weight, overweight, and obese groups based on body mass index. Health status was assessed using data from the health questionnaire and examination. Nutritional status was assessed using data from 24-hour dietary recall and a food frequency questionnaire. Results: The underweight group had higher education and exercised less than the obese group. Means of blood chemistry and blood pressure of the underweight group did not differ from those of the normal weight group. Means of fasting glucose, insulin, lipid profiles, blood cell counts, and blood pressure in the underweight group were different from those of the overweight or obese group. Proportions of delivery, breast feeding, and irregular menstruation in the underweight group were lower compared with the other groups. Except retinol intake, means of nutrient intake did not differ among four groups. There were significant differences among four groups in the intakes of cereals and eggs and frequency of consumption of dairy products. Conclusion: The current findings showed that health and nutritional status of underweight women in their twenties did not differ from those of normal weight women. In particular, health status of underweight women in their twenties was better than that of obese women of the same ages. Further study on health and nutritional status of extremely underweight women is necessary.

Recent studies described the ${\varepsilon}4$ allele of apoE confers a two-to fourfold increased risk for late-onset Alzheimer#s disease (LOAD), but LOAD pathology does not all fit neatly around apo E. Therefore, the goal of this study was to find the association between Alzheimer and apo E4 genotype in the 107 elderly between 50 to 64 years old who visited to FHWC of Sungshin Women#s University. We conducted the questionnaire survey (general & 24 hr dietary recall), anthropometerics (BP, waist & BMI) and blood biochemistry (FBS & lipid profiles). LDL-c and HOMA-IR were calculated by Friedwald#s and Matthew#s formulas. The apo E genotyping was performed by PCR-RFLP method and subjects were divided into three allele groups (${\varepsilon}3$; wild, ${\varepsilon}2$ & ${\varepsilon}4;$ mutants). The apo E allele frequencies were 7.0% for the ${\varepsilon}2$, 83.6% for the ${\varepsilon}3$ and 9.3% for the ${\varepsilon}4$. In comparison with biochemistry characteristics by apo E genotype, FBS was significantly higher in ${\varepsilon}4(129.2{\pm}6.8)$ than that in the others (${\varepsilon}2$: $117{\pm}7.4$, ${\varepsilon}3$: $107.3{\pm}2.2)$ (p<0.01). More than forty percents of ${\varepsilon}4$ group shown the dyslipidemia [high TG (>150mg/dl) & low HDL (<40 mg/dl:male or <50 mg/dl: female)]. The cytokines levels such as IL-1 ${\beta}$, IL-6 and $TNF-{\alpha}$ were not different among three apoE alleles. After the adjusting sex, age & dietary fiber, LDL-c level was siginificantly higher in ${\varepsilon}4$ ($108.3{\pm}7.7$) than that in ${\varepsilon}2$ ($100.4{\pm}8.4$) (p<0.05). According to food intake and the recipe on the basis of 24 hr dietary recall, the elder]y with ${\varepsilon}4$ allele took higher intake frequency of the light -colored vegetable (radish, onion & cabbage) and pan-fried foods (sauteed beef and vegetables, stir-fried vienna with vegetables) than the others. We knew that the elderly with ${\varepsilon}4$ allele had been restricted the calories intakes with high dietary fiber (33.6+2.5 g/d) to maintain the normal level of FBS and LDL-c. On next study, the prevalence of Alzheimer#s disease in this population who has ${\varepsilon}4$ allele on the condition of calories restriction will be continually follow-up.

The anti-obesity effects of fermented black bean were tested with mice fed a high fat diet for seven weeks. Body weight gain and feed efficiency ratio (FER) in the high fat diet control (HC) group were markedly higher, compared with those of the normal control (NC) group, but were significantly lower in the 2% black bean powder supplemented high fat diet (BB) group and 2% black bean powder fermented by M. pilosus supplemented high fat diet (BBM) group, compared with those of the HC group. Food intake in the HC and BB groups was significantly lower than that of the NC and BBM groups. Water intake in the HC group was significantly lower than that of the NC group, but was higher in the BB and BBM groups, compared with that of the HC group. On the other hand, relative liver and kidney weight in the HC group was lower than that of the NC group, but was higher in the BB and BBM groups, compared with that of the HC group. In addition, whereas epididymal fat weight in the HC group was markedly higher than that of the NC group, it was significantly lower in the BB and BBM groups, compared with that of the HC group. Meanwhile, hepatic GSH in the HC group was significantly lower than that of the NC group, but was slightly higher in the BB and BBM groups, compared with that of the HC group. Although hepatic LPO in the HC group was dramatically higher than that of the NC group, it was significantly lower in the BB and BBM groups, compared with that of the HC group. In addition, serum TG, total cholesterol, and LDL-cholesterol in the HC group was significantly higher than that of the NC group, but was significantly lower in the BB and BBM groups, compared with that of the HC group. On the contrary, HDL-cholesterol in the HC group was significantly lower than that of the NC group, but was higher in the BB and BBM groups, compared with that of the HC group. In addition, activity of XOR D type in the HC group was lower than that of the NC group, but was slightly higher in the BB and BBM groups, compared with that of the NC group. Activities of ROS scavenging enzymes, such as SOD, GPX, and GST in the HC group were significantly lower than those of the NC group, but were significantly higher in the BB and BBM groups, compared with those of the HC group. In addition, serum ALT activity in the HC and BB groups was higher than that of the NC group, but was significantly lower in the BB and BBM groups, compared with that of the HC group. In histopathological findings, hepatic fat accumulation in the HC group was higher than that of the NC group, but was lower in the BBM group, compared with that of the HC and BB groups. In particular, antiobese, hypolipidemic, and antifatty liver effect of black bean powder fermented by M. pilosus was specifically higher than that of non-fermented steamed black bean. In conclusion, the constituents of black bean fermented by Monascus pilosus have been proven to not only inhibit obesity and hyperlipidemia but also decrease hepatic fat accumulation in high fat diet-induced obese mice.

Objective: The aim of this study was to compare day 3 embryo transfer (D3ET) with day 5 ET (D5ET) in fresh in vitro fertilization (IVF) cycle on pregnancy outcomes. Methods: We conducted a retrospective matched case control study that included 90 women with D3ET and 90 women with D5ET from January 2007 to June 2009. Subjects were matched for reproductive profiles and IVF cycle characteristics. Two good quality embryos were transferred in both groups. Pregnancy rates (PR), implantation rate, and multiple PR were compared. Results: Demographics, stimulation parameters and embryological data were comparable in both groups. Main pregnancy outcomes with D3ET and D5ET groups were not statistically different: implantation rate (39.4% vs. 32.8%), positive PR (57.8% vs. 46.7%), clinical PR (53.3% vs. 45.6%), ongoing PR (50.0% vs. 42.2%), respectively. Both groups showed high multiple PR (37.5% vs. 34.1). Conclusion: D5ET may not be beneficial and necessary in comparison with D3ET on pregnancy outcomes, and elective single ET should be considered to decrease multiple pregnancies in women with favorable conditions and good quality embryos undergoing IVF.

This study investigated the characteristics of nitrogen removal and microbial community in a lab-scale A$_2$O activated sludge process filled with the fluidized media at an aerebic basin. The change of microbial community was monitored based on quinone profiles of activated sludge according to feeding sewage with/without external carbon source. Low C/N ratio(COD$_{Cr}$/T-N of 1.24) sewage was fed. The obtained results from this study were as follows; Ubiquinone(UQ) in the influent was in the descending order of UQ-8, UQ-10 and UQ-9. Menaquinone(MK) was simpler and much less than UQ. The ratio of UQ/MK was less than 0.41 and the dissimilarity was below 0.26. Without an external carbon source, MK-8 was the dominant species and there were 3 kinds of quinone species and low DQ and EQ values in an anaerobic basin. The ratio of UQ/MK increased to 2.3 in an anoxic basin. In an oxic basin, UQ-7 and UQ-8 were the dominant species. UQ-7 was dominating in suspended microorganisms, while UQ-8 was in attached microorganisms. With an external carbon source addition, MK-8 decreased but UQ-8 increased in an anaerobic basin. So did quinone species, DQ and EQ values. There was also a change in an anoxic basin with the improvement of denitrification. UQ-8 decreased instead, MK-7 and MK-8 increased. UQ/MK ratio decreased 2.3 to 1.4. It means that the dominant species change from Pseudomonas sp. to Bacillus and Micrococcus species. etc. In an oxic basin, UQ-8 replaced UQ-7 in suspended microorganisms and UQ-10 replaced UQ-8 in attached microbials. This seemed related with the growth of Nitrosomonas and Nitrobactor species.

Purpose : The aim of this study was to investigate the epidemiologic and clinical profiles of Kawasaki disease(KD) in children 8 years of age and older. Methods : For the epidemiologic study of KD in Korea, data of total 15,692 KD patients were collected from 1994 to 2002 on a 3 year basis, by the retrospective survey. Among them, data of 211 KD patients 8 years of age and older were analyzed and compared with those of the KD patients less than 8 years of age. Results : 211 patients 8 years of age and older(1.3% of total KD patients) with the mean age of 9.8 years, included 142 cases aged 8-10 years, 42 cases aged 10-12 years, and 27 cases aged 12 years and older. The male-to-female ratio was 1.9 : 1, the recurrence rate was 3.8%, and the prevalence of cases in sibling was zero. Coronary arterial(CA) abnormalities were detected by echocardiography in 25.4% of the cases, including 7.6% of CA aneurysm cases. There was 1 case complicated by myocardial infarction. Conclusion : Comparing with the data of the KD patients less than 8 years of age, data of 211 patients 8 years of age and older showed significantly higher incidences of CA abnormalities(25.4% : 19.8%) and CA aneurysms(7.6% : 4.0%).

Purpose : Pharmacologic provocation test of growth hormone(GH) is a non-physiologic method and has several limitations for diagnosing growth hormone(GH) deficiency. Spontaneous GH release studies could be important in understanding the pathophysiology of children with poor growth but normal responses to GH provocation tests. Also, the relationship between nocturnal GH secretions and sleep patterns in short stature children is poorly understood. The aim of this study is to determine whether there are differences in sleep patterns and nocturnal GH secretory profiles between idiopathic short stature children and a normal stature group. Methods : Spontaneous nocturnal GH secretions and sleep patterns were evaluated in 12 prepubertal idiopathic short stature children with normal responses to provocation tests and 9 normal stature controls. Blood samples were taken every 30 minutes from 22:00-06:30 and sleep patterns were analyzed by polysomnography. Results : The mean GH level during sleep was significantly lower in short stature children than in controls. The peak GH level after sleep, coincident with the first slow wave sleep, was lower in the short stature group. The slow wave sleep times of short stature children were decreased compared with those of normal subjects. Conclusion : These results suggest that overnight serial GH sampling is helpful to identify short stature children with subnormal GH secretions, and sleep structure differences may be associated with decreased overnight GH secretions in short stature children.

Purpose : Lower respiratory tract infections in infant and young children are often due to a virus, especially the Respiratory syncytial(RS) virus. Chest X-ray findings in bronchiolitis and bronchopneumonia are different. The radiographic hallmark of bronchiolitis is pulmonary hyperinflation and similar to that of bronchial asthma. Bronchiolitis is predisposed to later development of bronchial asthma. To evaluate the difference of immuno-pathophysiology between bronchiolitis and bronchopneumonia, we measured $IFN-{\gamma}$(Th1 cytokine), IL-5(Th2 cytokine) and ECP. We also investigated whether X-ray findings in infants with viral infected respiratory disease are useful in predicting the development of asthma. Methods : We measured IL-5, ECP, $IFN-{\gamma}$ levels in serum from 21 infants with bronchiolitis and 21 infants with bronchopneumonia and 16 infants without pulmonary viral diseases. Results : IL-5 levels of bronchiolitis and bronchopneumonia were significantly higher than those of the control(P=0.02, P=0.042). IL-5 levels of bronchiolitis were higher than those of bronchopneumonia but there was no significant difference. $IFN-{\gamma}$ levels of bronchopneumonia were higher than those of bronchiolitis but there was no significant difference. ECP levels of bronchiolitis and bronchopneumonia were higher than those of the control but only those of bronchiolitis were significantly higher than those of the control(P=0.045). IL-5 and ECP levels did not show any significant correlation in bronchiolitis, bronchopneumonia and control groups. Conclusion : We cannot prove the distinct differences in serum Th1/Th2 cytokine profiles between bronchiolitis and bronchopneumonia in infants. These results suggest that the different findings on chest X-ray between bronchiolitis and bronchopneumonia could not be a predictor of later development of asthma.

Purpose : Every year, there is a remarkable increase in the prevalence of children with excess body fat. The aim of this study is to find a useful screening method in assessing adolescent, obesity and to specify the predictable risk factors that are related to adult cardiovascular disease according to BMI and obesity index. Methods : From July to November in 2001, a total of 2,814(male : female=2,011 : 803) mid to high school students who were in the obesity range according to obesity index(>20%) were evaluated according to height, weight, body mass index(BMI), obesity index, and serum lipid levels. Results : Among the obese students over 20% by obesity index, 86.6% were over the range of 95 percentile by BMI. Among students defined as obese by BMI, 21.0% of males and 21.4% of females students had hypercholesterolemia; by obesity index, the ratio was 20.7% male and 19.0% female. The frequency of hypertriglyceremia in male students was 15.0% in group I(overweight group, 85P97p); in female students 11.8%, 20.7% and 28.2% respectively. Conclusion : In this study, using BMI alone to test the serum lipid level in adolescent obesity had a limit of 10.0-17.0% omission. Therefore using obesity index as a screening method to find the adult cardiovascular disease would rather reduce the omission rate. The risk factor of cardiovascular disease according to BMI was the increasing level of triglyceride in both male and female students. We think that using the obesity index has more rationale rather than BMI in assessing lipid profiles.

Purpose : The actual clinical examples of co-appliance of catheter intervention with surgical procedures in the treatment of pulmonary atresia with an intact ventricular septum(PA/IVS) which we have experienced in our institution are here shown, and the anatomical and hemodynamical profiles between each method is compared. Methods : Medical records of 33 patients with PA/IVS who underwent various treatment from January, 1995 to December, 2000 were reviewed for a retrograde study. Results : In three out of 10 patients who underwent percutaneous balloon pulmonary valvotomy (PPV), residual pulmonary stenosis were observed in their out patient department(OPD) follow-ups, eventually necessitatig balloon pulmonary valvuloplasty(BPV). One out of three patients exhibited deterioration of tricuspid regurgitation after BPV, requiring surgical tricuspid annuloplasty(TAP). Two out of the seven patients who received primarily surgical right ventricle outlet tract(RVOT) repair without any systemic-pulmonary shunt or intervention needed additional intervention employing cardiac catheterization after operation. Two patients received interventional catheterization before surgical RVOT repair. In five out of 11 cases of Fontan type operation, coil embolization of collateral circulation was done before total cavo-pulmonary connection(TCPC), and in three cases, interventional catheterization was needed after TCPC. Conclusion : Both medical and surgical treatment modalities are widely used in management of PA/IVS patients, and recent results prove that medico-surgical cooperative treatment is essential.
