It has been reported that Chungkukjang, one of Korean traditional fermented soybean products, may improve hypertension, diabetes, and hyperlipidemia. In this study, we sought to investigate the immunoenhancing effects of Chungkukjang in ovariectomized mice. For the first period, female SLC ddy mice were either sham-operated (Sham; n=27) or ovariectomized (OVX; n=27). As a basal diet, ovariectomized mice were fed low-calcium diet for faster induction of osteoporosis for six weeks, and those in the Sham group were fed AIN-76 diet. For the second period, half of the OVX group (n=9) and the Sham group (n=9) were fed a Chungkukjang-based diet (CKJ); whereas the other half (OVX; n=9/ Sham; n=9) were fed a casein-based diet (CSI) for 8 weeks. After a second period, we collected the blood via heart puncture and measured the splenocytes proliferation, T lymphocyte subsets by flowcytometry, and levels of serum cytokines (IL-2, IL-4, IL-6, IL-10, IFN-${\gamma}$ and TNF-${\alpha}$) by ELISA assay. The OVX+CKJ group showed higher splenocytes proliferation, higher ratio of CD4/CD8, and lower levels of IL-6 and TNF-${\alpha}$ cytokines compared to the OVX+CSI group. The Sham+CKJ group showed cytokine productions, such as higher levels of IL-10 and IFN-${\gamma}$, and lower levels of IL-6 and TNF-${\alpha}$ compared to the Sham+CSI group. The result of this study suggests that Chungkukjang may lower the proinflammatory cytokine levels in both the OVX and Sham groups. In addition, Chungkukjang could make a balance of T cell subset proliferations and enhance the splenocyte proliferations in the OVX group.

The assessment of sodium intake is complex because of the variety and nature of dietary sodium. This study intended to develop a dish frequency questionnaire (DFQ) for estimating the habitual sodium intake and a short DFQ for screening subjects with high or low sodium intake. For DFQ112, one hundred and twelve dish items were selected based on the information of sodium content of the one serving size and consumption frequency. Frequency of consumption was determined through nine categories ranging from more than 3 times a day to almost never to indicate how often the specified amount of each food item was consumed during the past 6 months. One hundred seventy one adults (male: 78, female: 93) who visited hypertension or health examination clinic participated in the validation study. DFQ55 was developed from DFQ112 by omitting the food items not frequently consumed, selecting the dish items that showed higher sodium content per one portion size and higher consumption frequency. To develop a short DFQs for classifying subjects with low or high sodium intakes, the weighed score according to the sodium content of one protion size was given to each dish item of DFQ25 or DFQ14 and multiplied with the consumption frequency score. A sum index of all the dish items was formed and called sodium index (Na index). For validation study the DFQ112, 2-day diet record and one 24-hour urine collection were analyzed to estimate sodium intakes. The sodium intakes estimated with DFQ112 and 24-h urine analysis showed $65\%$ agreement to be classified into the same quartile and showed significant correlation (r=0.563 p<0.05). However, the actual amount of sodium intake estimated with DFQ112 (male: 6221.9mg, female: 6127.6mg) showed substantial difference with that of 24-h urine analysis (male: 4556.9mg, female: 5107.4mg). The sodium intake estimated with DFQ55 (male: 4848.5mg, female: 4884.3mg) showed small difference from that estimated with 24-h urine analysis, higher proportion to be classfied into the same quartile and higher correlation with the sodium intakes estimated with 24-h urine analysis and systolic blood pressure. It seems DFQ55 can be used as a tool for quantitative estimation of sodium intake. Na index25 or Na index14 showed $39\~50\%$ agreement to be classified into the same quartile, substantial correlations with the sodium intake estimated with DFQ55 and significant correlations with the sodium intake estimated with 24-h urine analysis. When point 119 for Na index25 was used as a criterion of low sodium intake, sensitivity, specificity and positive predictive value was $62.5\%,\;81.8\%\;and\;53.2\%$, respectively. When point 102 for Na index14 was used as a criterion of high sodium intake, sensitivity, specificity and positive predictive value were $73.8\%,\;84.0\%,\;62.0\%$, respectively. It seems the short DFQs using Na index 14 or Na index25 are simple, easy and proper instruments to classify the low or high sodium intake group.

Purpose: The purpose of this study is to compare perinatal outcomes between in vitro fertilization (IVF) twins and naturally conceived twins born to women aged 35 years or older and to provide basic information for taking care of IVF twins born to women aged 35 years or older. Methods: We reviewed the records of perinatal and neonatal outcomes in 288 IVF twins and 220 naturally conceived twins born to women aged 35 years or older between January 2001 and December 2010 at CHA Bundang Medical Center. Results: No difference was observed in the maternal ages of mothers giving birth to IVF twins and those giving birth to naturally conceived twins. Gestational ages and birth weights of IVF twins were not different from those of naturally conceived twins. Various perinatal outcomes, including gestational diabetes mellitus, pregnancy-induced hypertension, placenta previa, premature amniotic membrane rupture, and need for a Cesarean section did not differ between the 2 groups. However, the 1-min and 5-min Apgar scores (P=0.019 and P=0.045, respectively) were different between the 2 groups. The incidence of early-onset sepsis was lower in the IVF twins than in the naturally conceived twins (P=0.02). However, the 2 groups did not show any difference in the incidence of respiratory distress syndrome, bronchopulmonary dysplasia, patent ductus arteriosus, necrotizing enterocolitis, intraventricular hemorrhage, and other congenital anomalies. Conclusion: The perinatal outcomes in IVF twins born to women aged 35 years or older were not significantly different from those of naturally conceived twins.

Purpose: Intrauterine growth retardation (IUGR) is the term used to designate a fetus that has not reached its growth potential. However it is difficult to make a distinction between infants who are constitutionally small and growth restricted small. In the present study, we focused on the clinical characteristics and the hematologic value in small for gestational age (SGA) infants and discussed how to distinguish intrauterine growth restricted infants from constitutionally small infants. Methods: SGA infants that did not have any other risk factors for IUGR in the medical record except maternal hypertension (HTN) and diabetes mellitus (DM) and born at the Seoul St Mary's Hospital and Yeouido St Mary`s Hospital from January 2007 to July 2010 were included. The frequency of IUGR is higher in the pregnancy with medical problem, and in preterm infants. Therefore, the data was categorized by maternal disease and gestational age. We assessed the clinical data and the hematologic value. Results: The leukocyte count and the platelet count were lower in the SGA with maternal HTN group and the preterm SGA group. There was no difference in the clinical data and the prognosis resulted from maternal HTN and maternal DM. However, the hematologic difference was not found in the categorization of the preterm SGA group as maternal diasease. Conclusion: The results of this study showed that it is possible the low leukocyte count and the low platelet count are the characteristic hematologic features in growth restricted small for gestational age infants.

The purpose of this study was to investigate the relationship between excessive daytime sleepiness (EDS) and blood pressure (BP) in patients with obstructive sleep apnea-hypopnea (OSAH). Patients were classified into four groups based on their severity of polysomnographic data: the snoring group (n=108)-characterized by Apnea-Hypopnea Index (AHI<5); the mild OSA group (n=186)-AHI $5{\leq}AHI$<15; the moderate OSA group (n=179)- AHI $15{\leq}AHI$<30; and the severe OSA group (n=233)-$AHI{\geq}30$. On the same night of polysomnography (PSG), BP levels were measured before sleeping (bedtime BP) and immediately after waking up on the following morning (morning BP). EDS was recognized as ESS (epworth sleepiness scale)${\geq}9$. The differences and correlations between BP and PSG parameters in the EDS and non-EDS groups of OSAH patients were analyzed. MAP was positively correlated with BMI, AHI, and total arousal (r=0.099, r=0.142, r=0.135, p<0.01, p<0.01, p<0.01), while negatively correlated with mean $SaO_2$ (r=-0.258, p<0.01). The EDS group had overall younger population ($47.2{\pm}11.3$ vs $50.3{\pm}11.4$, p=0.023), higher DBP (both bedtime and morning, $83.1{\pm}9.7$ vs $81.4{\pm}8.8$ and $86.4{\pm}9.2$ vs $83.6{\pm}9.7$)(p=0.031, p=0.047), and higher SBP (both bedtime and morning, $126.7{\pm}11.2$ vs $123.4{\pm}12.4$, $128.9{\pm}12.4$ vs $125.3{\pm}12.9$)(p=0.021, p=0.021) than compared with the non-EDS group. In hypertensive OSAH patients, patients with EDS were also younger and had higher total arousal number, as well as higher morning and bedtime DBP and SBP than compared with the non-EDS group (p<0.005, p=0.008, p<0.001 and p<0.001). EDS in OSAHS patients is a special phenotype characterized by younger age, higher DBP, more severe desaturation, and hypertension.

Gastrodia elata blume (GEB) is considered to be a useful herbal medicine in oriental countries for the treatment of headache, migraine, dizziness, childhood convulsion, epilepsy, rheumatism, hypertension, neuralgia and neurological disorders. This study was carried out to investigate the quality of bread added with the powder of GEB. The possibility of GEB wheat flour mixture as bread was studied by adding 0%, 0.5%, 1.0%, 1.5%, 2.0% of GEB powder to wheat flour. In Farinograph data, the dough stability decreased with the increase of GEB powder. Granular size of starches ranged from $36\;{\mu}m\;to\;60{\mu}m$, and the shape of them showed a long oval figure. Amylograph showed that the increase in the ratio of GEB on the doughs slightly elevated in the maximum viscosity. The loaf volume of 0.5% powder increased by 10.2% but that of 2.0% decreased by 16.8%. The moisture content was 43.57% in the control but it increased as the powder addition. The colors of crust and crumb were not significantly different among L, b and ${\Delta}E$, but 'a' value in crumb was increased as the powder addition. The addition of the powder had no significant effect on bread texture. In sensory evaluation, the moistness increased as the increase of the powder addition. The control bread was most excellent, and the bread made by mixing additives were better than just 0.5% GEB-wheat flour in terms of quality.

Purpose : The urinary tract infection associated with vesicoureteral reflux(VUR) in children may result in serious complications such as renal scarring, hypertension, proteinuria and end stage renal disease. The purpose of this study was to evaluate the factors affecting renal scar such as age, gender, grade of VUR, and ACE gene polymorphism, and body growth in the patients with and those without renal scar associated with VUR Methods : During the period from January 1994 to July 2000, We had 93 children with urinary tract infection associated with VUR who were admitted to the Department of pediatrics of Chonbuk National University Hospital. The patients were divided into two groups according to follow up 99mTc-DMSA renal scan; patients with renal scar group and those with non-scar group. We analyzed and compared the factors associated with renal scarring between the two groups. Results : There were no significant difference in gender, causative organism, ACE gene polymorphism, height and weight at diagnosis between renal scar group and non-scar group. Fifty four patients were in renal scar group and forty seven of them had VUR. The age at diagnosis was significantly higher in renal scar group (2.48${\pm}$2.64yr) than in non renal scar group (1.26${\pm}$1.83yr). Especially, the infants who were less than 1 year of age with VUR developed relatively more renal scar compared with infants older than 1 tear of age. The incidence of renal scarring showed a direct correlation with the severity of VUR. Conclusion : The factors affecting renal scar formation were age at diagnosis, presence and grade of VUR, but the other factors such as gender, causative organism, ACE gene polymorphism were not associated with renal scarring. Therefore, further evaluation about uropathogenic E coli and foflow up study about body growth associated with severity of renal scar would be necessary. (J.

Purpose : Neonatal bacterial meningitis is the disease which clinical manifestations are nonspecific and several neurologic complications may occur. We studied neonatal bacterial meningitis, particularly in treatment and prognosis according to causative organisms -gram positive and gram negative bacteria- to assist in treatment of neonatal bacterial meningitis. Methods : We analysed twenty-four cases retrospectively who had been admitted in NICU or pediatric ward in Chung-ang Gil hospital from Jan. 1991 to Jun. 1996, and who had proven causative organisms in culture or latex agglutination[n test in CSF. Results : 1) The ratio of male to female was 2.4: 1. The mean birth weight and gestational age in cases with gram positive bacterial meningitis were $2.91{\pm}0.79kg$ and $38.4{\pm}2.74$ weeks and those in cases with yam negative bacterial meningitis were $3.30{\pm}0.90kg$ and $37.7{\pm}3.33$weeks respectively. There was no significant difference between the two groups. 2) The perinatal predisposing factors were pematurity, mecoinium staining amnionic fluid, matemal diabetes and pregnancy-induced hypertension, etc. The clinical manifestations Were fever, seizure, poor oral intake and fontanel bulging, etc. There were eleven cases with early onset bacterial meningitis(four cases by gram positive bacteria, seven cases by gram negative bacteria), and thirteen cases with late onset bacterial meningitis(seven cases by gram positive bacteria, six cases by gram negative bacteria). There was no significant difference between the two groups in terms of onset. 3) There were eleven cases with yam positive bacterial meningitis and they were coagulase-negative staphylococci(three cases), group B streptococci(three cases), Staphylococcus aureus(two cases), Streptococcus viridans(two cases), and enterococci(one case). And there were thirteen cases with gram negative bacterial menir gitis and they were Escherichia coli(seven cases), Klevsiella pneumoniae(three cases), Pseudomonas aeruginosa(one case), Acinetobactor(one case) and Enterobacter(one case). 4) The initial CSF WBC counts in cases with yam negative bacterial meningitis were significantly higher than those in cases with gram positive bacterial meningitis but the CSF protein and glucose levels were no significant difference in the two groups statistically. 5) The number of cases with abnormal findings in brain ultrasonography was seven in gram positive bacterial meningitis and ten in gram negative bacterial meningitis. 6) There were relatively high sensitivity to penicillin derivatives, the first generation cephalosporin and vancomycin in gram positive bacteria and to the third generation cephalosporin and amikacin in gram negative bacteria. 7) The mortality rate was 20.8%(5 cases were expired or discharged hopelessly). There was no significant difference between the two groups in prognosis. Conclusions : We recommend active treatment in noenatal bacterial meningitis to improve prognosis because the prognosis is poor.

Background: Coronary artery fistula is rare congenital anomaly, which account for $0.27\~0.40\%$ of all congenital heart diseases. We report the clinical observations of 45 patients with coronary artery fistula. Material and Method: We reviewed all patients presented with or without symptoms of coronary artery fistula between 1987 and 2004. Age ranged from 1 to 83 years. Twenty-six patients were female. The patients were divided into 2 groups according to the presenting symptoms. Twelve patients were in group A (asymptomatic) and 33 patients in group B (symptomatic). The most common clinical presentation in group B was angina (18) followed by dyspnea (7), atypical chest pain (5), syncope (1), fatigue (1), and palpitation (1). Twenty-five patients were associated with other cardiac diseases, which were atrial septal defect (4), coronary artery occlusive disease (6), hypertension (12), and valvular heart disease (2). Result: Patients were followed-up for a mean period of $64.8\pm62.7$ months. There was no complication related to coronary artery fistula during the follow-up period in both group. There was no mortality related to coronary artery fistula. Conclusion: In symptomatic patients, early surgical treatment is recommended considering the low perioperative morbidity. In asymptomatic patients receiving medical treatment, close follow up may be necessary.

Many surgical techniques for ischemic mitral regurgitation (IMR) have been used with their excellent results and advantages. Here, we report our simple posterior annuloplasty techniques using vascular graft strip with their early results. Material and Method: Twenty two patients (13 male) underwent the operations for IMR (excluding the papillary muscle rupture) from December 2001 to January 2003. Preoperative risk factors were low ejection fraction (<35％, n=9), hypertension (n=13), diabetes (n=9), and renal failure (Cr>2.5, n=4). The wide dissection beneath the both vena cavae and interatrial groove after bicaval cannulation enabled the easy exposure of mitral valve even in the small left atrium. After eight or nine interrupted sutures in posterior annulus for anchoring the 6 mm width vascular graft strip, symmetric (n=8) or asymmetric (n=14) annuloplasty were done. Combined surgeries were CABG (n=21), Dor procedures (n=3), tricuspid valve annuloplasty (n=1), Maze operation (n=1), and aorto-right subclavian artery bypass (n=1). Result: Except for one surgical mortality, all the patients were doing well and the mean grade of regurgitation was decreased from 2.95 to 0.88, however the ejection fraction had not changed significantly just before discharge. Post-operative valve function evaluated before discharge revealed no residual regurgitation in 8 (including 1 patient with mild stenosis due to over reduction), minimal in 11, mild in 2, and mild to moderate regurgitation in 1. One patient who had ischemic cardiomyopathy and renal failure died of the arrhythmia during the hemodialysis. Conclusion: These observations suggest that the annuloplasty with vascular graft strip could be a safe and cost effective techniques for ischemic mitral regurgitation. However, the long term evaluation for the mitral valve function should be defined for the final conclusion.
