PURPOSE: To construct new Korean reference curves for birth weight by sex and gestational age using contemporary Korean birth weight data and to compare them with the Lubchenco and the 2010 United States (US) intrauterine growth curves. METHODS: Data of 2,336,727 newborns by the Korean Statistical Information Service (2008-2012) were used. Smoothed percentile curves were created by the Lambda Mu Sigma method using subsample of singleton. The new Korean reference curves were compared with the Lubchenco and the 2010 US intrauterine growth curves. RESULTS: Reference of the 3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles birth weight by gestational age were made using 2,249,804 (male, 1,159,070) singleton newborns with gestational age 23-43 weeks. Separate birth weight curves were constructed for male and female. The Korean reference curves are similar to the 2010 US intrauterine growth curves. However, the cutoff values for small for gestational age (<10th percentile) of the new Korean curves differed from those of the Lubchenco curves for each gestational age. The Lubchenco curves underestimated the percentage of infants who were born small for gestational age. CONCLUSION: The new Korean reference curves for birth weight show a different pattern from the Lubchenco curves, which were made from white neonates more than 60 years ago. Further research on short-term and long-term health outcomes of small for gestational age babies based on the new Korean reference data is needed.

PURPOSE: The objective of this study is to estimate the trend in age at menarche in the Korean female and evaluate the relationship between age at menarche and adult body mass index (BMI), which is a indicator of later-life health. METHODS: We conducted a cross-sectional analysis of a nationally representative sample (self-reported age at menarche and measured height and weight) of 11,065 females aged 15 and older. Data were obtained from the Fourth Korea National Health and Nutrition Examination Survey (KNHANES IV, 2007-2009). RESULTS: We found a statistically significant decline in age at menarche in successive birth groups, indicating a 0.726 year decrease per decade. The age at menarche in 1990-1994 year birth group was 12.60 years, which showed a significant decreased from 3.11 years in the 1980-1984 birth group. We also found a significant negative association between age at menarche and current BMI. A one-year decrease in age at menarche was associated with mean BMI increase of 0.109 kg/m2 (95% confidence interval [CI], 0.069 to 0.150) after adjustment for age. In multivariate logistic regression, the odds ratios of obesity in females with early menarche (<12 years) was 1.845 fold (95% CI, 1.441 to 2.361). CONCLUSION: We found that age at menarche is still falling in the Korean female. We also found that early menarche is a risk factor for obesity in adults.

PURPOSE: To obtain normative data on bone mineral density of each region of interest (ROI) measured by Hologic model dual-energy x-ray absorptiometry (DXA) of children and adolescents. METHODS: Cross sectional results from 723 healthy Korean children and adolescents (10-20 years of age) in the Korean National Health and Nutrition Examination Surveys were analyzed. We used age- and sex-specific reference data for bone mineral density (BMD) of the lumbar spine, femur neck, and total body except head from Hologic DXA device as recommended by the International Society for Clinical Densitometry. RESULTS: The bone mineral density of each ROI increased with age in both boys and girls. Maximal increase in the lumbar BMD occurred between ages 11 and 12 in girls and between ages 12 and 14 in boys. However, the increases of BMD in each ROI were different. The plateaus of the lumbar spine and whole body except head BMD in girls occurred at ages 15 and 17, respectively. The plateaus of BMD in each ROI occurred at age 17 in boys. CONCLUSION: Most of the skeletal mass, including lumbar spine and total body except head, is reached before the end of the second decade. This study provides reference values for bone density of each ROI measured with DXA for children and adolescents.

Congenital diverticula of the cardiac ventricle have been reported as arising either from the left ventricule or, rarely from both ventricules. A diverticulum arising from the right ventricle alone is very rare. Double chambered right ventricle(DCRV) was first described in 1962 by Lucas et al, and account for 1.5% of congenital heart disease. Right ventricular diverticulum are associated with right ventricle outlet obstructive disease, tetralogy of fallot, double outlet right ventricle, pulmonic stenosis, ventricular septal defect, left ventricule-right atrium communication, persistant truncus arteriosus. DCRV are freqently associated with ventricular septal defect(80%), pulmonic stenosis(33%), renal anormaly(43%). Treatment consist of suture of diverticulum and resection of septum. We report a case of double chambered right ventricle with congenital right ventricular true diverticulum in 62 years of female patients admitted due to anterior chest pain and mild exertional dyspnea.

Journal of Veterinary Science 2003;4(3):269-275
Porcine epidemic diarrhea virus (PEDV) causes an acute enteritis in pigs of all ages, often fatality for neonates. PEDV occupies an intermediate position between two well characterized members of the coronavirus group I, human coronavirus (HCoV-229E)and transmissible gastroenteritis virus (TGEV) which uses aminopeptidase N (APN), a 150 kDa protein, as their receptors. However, the receptor of the PEDV has not been identified yet. A virus overlay protein binding assay (VOPBA) was used to identify PEDV binding protein in permissive cells. The binding ability of PEDV to porcine APN (pAPN) and the effects of pAPN on infectivity of PEDV in Vero cells were also investigated. VOPBA identified a 150 kDa protein, as a putative PEDV receptor in enterocytes and swine testicle (ST) cells. Further the PEDV binding to pAPN was blocked by anti-pAPN and pAPN enhanced PEDV infectivity in Vero cells. In conclusion, these results suggested that pAPN may act as a receptor of PEDV.

A 42-year-old male was hospitalized with abdominal pain, dyspnea, and turbid peritoneal fluid. He was diagnosed with hypertension, diabetes and started continuous ambulatory peritoneal dialysis (CAPD) 11 months ago. He was treated with intraperitoneal cefazolin and ceftazidime, and then white blood cell counts of dialysate decreased. Incidentally, liver abscess was found in chest CT performed for the evaluation of dyspnea, and patient was febrile persistently. So percutaneous abscess drainage was done by pigtail catheter. We changed the antibiotics to ceftriaxone and metronidazole, and hemodialysis was started. Klebsiella pneumoniae was cultured from peritoneal fluid and blood simultaneously. We concluded that liver abscess is a primary cause of CAPD peritonitis.

An indirect porcine epidemic diarrhea (PED) virus (PEDV) enzyme-linked immunosorbent assay (ELISA) was compared with the serum neutralization (SN) test by testing 46 samples from experimentally infected sows, 73 samples from naive sows, and 1, 024 field sow samples from 48 commercial swine farms of undefined PED status. The SN test and the ELISA were performed using PEDV, KPEDV-9 strain. Viral proteins as a coating antigen of PEDV ELISA were extracted from the cytoplasm of PEDV-infected Vero cells using a non-ionic detergent, Triton X-100, and a simple protocol of PEDV ELISA was followed. The presence of antibodies in these experimental samples was confirmed by SN and ELISA in which the sensitivity of the ELISA was 89.1%, and the corresponding specificity was 94.5%. On testing 1, 024 field samples, an overall agreement of 84.2% was generated between the SN and ELISA. This study demonstrates that the PEDV ELISA is a useful serodiagnostic screening test at herd level for detecting swine antibodies against PEDV.

A few members of coronavirus group I which includes porcine epidemic diarrhea virus (PEDV) use porcine aminopeptidase N (pAPN) as a cellular receptor. Cellular receptors play an important role in virus attachment and entry. However, the low permissiveness of PEDV to APN-expressing porcine cell lines has made it difficult to elucidate the role of pAPN in vitro. The purpose of this study was to prove whether the treatment of soluble pAPN could enhance the antibody production against PEDV in guinea pigs, rabbits and sows. The animals (20 guinea pigs, 8 rabbits and 20 sows) were divided into 4 groups. Group A was injected intramuscularly (IM) with soluble pAPN at one hour before intramuscular infection of PEDV on the same site, group B for IM simultaneous injection of pAPN and PEDV, and group C for IM injection of PEDV only. Group D served as a control of pAPN treatment or PEDV infection. Antibody production against PEDV was compared among groups at regular intervals. The results suggested that pAPN could enhance the antibody production against PEDV in guinea pigs and rabbits which are free of pAPN, however, the effect of pAPN treatment in sows was not clearly elucidated.

Selective arterial embolization can reduce the size and pressure whtihin the nidus of the arteriovenous malformations(AVMS) and diminish the number of feeding pedicles, making subsequent surgical excision technically easier and safer, especially in those AVM patients whose lesions are judged to be inoperable or respectable with major risk. Authors have successfully and repeatedly performed selective arterial embolizations with polyvinyl alcoholfoam(PVA foam) and isobutyl-2-cyanoacrylate(IBCA) to a large AVM at the left basal ganglia, thalamus and lateral ventricles, and a large cortical AVM near right motor strip.
