Ovarian cysts in the newborn are uncormnon. Fetal ovarian cysts are being diagnosed with inaeasing fiequency with development of obstetrical sonography. Most of these cysts are found within the first few months of life and have no clinical significance. But, a large ovarian cyst would be founded antenatally with sonography. A large ovarian cyst can cause life-theatening complications during parturition and in the neonatal period. We have experienced a case of fetal ovarian cyst in a 32-year-old primiparous woman with antenatal sonography and report our experience with a brief review of literatures.

Recently identified second messenger molecules of signal transmission were derived from inositol phospholipid and several phospholipase C(PLC) isoenzyme were reconized. But the role of PLC in embryonal organ development, differentiation and growth is not described, yet. And, Siah gene of mouse is expressed at a higher level in a restricted number of sites during development. So, it is suggested that the Siah gene plays a significant role in development of vertebrates.Therefore, this study was aimed to investigate the role of PLC isoenzymes and Siah gene during murine fetal development by use of immunehistochemistry. The results are as follow: 1. PLC-beta1 and PLC-gammal are expressed apparently at early fetal stage, PLC-betal is observed focally, whereas PLC-gamma1 is diffusely expressed. 2. PLC-delta1 is not expressed during early and mid murine fetal age but strongly expressed in placental tissue. 3. PLC-beta1 is observed mainly in neural tissues including brain at mid fetal stage. PLC-gamma1 is expressed in entire organs, especially in liver tissue, and then their expression is reduced after mid stage. 4. Siah gene product is significantly expressed in olfactory epithelium, retina, neuron of brain and choroid plexus from mid fetal stage to late gestation. These results suggest that PLC-betal play a important role in central neural development and PLC-gamma1 in entire orgaans, especially in liver development. The strong expression of PLC-deltal in placenta suggest its involvement in early development, indirectly. Siah gene product expressed at a higher levels in olfactory epithelium, retina, neuron and choroid plexus, so Siah gene may play a important role in these organ developments.

BACKGROUND AND OBJECTIVES: The nasal epithelium is the first barrier encountered by airborne allergens and is an active participant in airway inflammation. The aim of this study was to determine the activation mechanism of nasal epithelial cells with Alternaria and the effect of rhinovirus on the Alternaria induced activation of nasal epithelial cells. MATERIALS AND METHODS: Cultured epithelial cells were stimulated by Alternaria with or without rhinovirus-16 (RV-16) infection. Release of interleukin (IL)-6, IL-8, and granulocyte macrophage colony-stimulating factor (GM-CSF) into culture supernatants were measured to determine the activation of epithelial cells. Nuclear factor-kappaB (NF-kappaB) and activator protein-1 (AP-1) of the epithelial cells were analyzed using western blot analysis. Intracellular NF-kappaB and AP-1 activity were evaluated by enzyme-linked immunosorbent assay. To determine the epithelial cell activation mechanism, cytokine production was inhibited with NF-kB, AP-1, and mitogen activated protein kinase (MAPK) inhibitors. RESULTS: Exposure of epithelial cells to Alternaria enhanced the production of cytokines. Intracellular NF-kB expression and activity were significantly increased by Alternaria, but not by RV-16. AP-1 expression and activity were not influenced by Alternaria. Increased IL-6 production was significantly inhibited by transcription factor inhibitors. However, IL-8 and GM-CSF production were not inhibited by these transcription factor inhibitors. CONCLUSIONS: Our in-vitro results demonstrate that Alternaria activates nasal polyp epithelial cells via NF-kB pathway and that NF-kB, AP-1, and MAPK are involved in the production of IL-6.

BACKGROUND: The prevalence of dementia is estimated to be as high as 5 10% over 65 years of age in Korea. It is important to evaluate of dementia for the elderly, because of the chronicity and progressiveness of the disease. However, cognitive impairment often goes unrecognized by physician because the many previous tools to evaluate cognitive function in the clinical setting are complex, time consuming and sometimes questionable correlation with real world functioning. The purpose of this study is to assess the usefulness of The Time and Change test as screening test for dementia ,on the basis of the correlation between this measure(T&C) and MMSE K. METHODS: The subject for this study consisted of 64 elderly who visited to the outpatient department of family medicine of the Ehwa Mok dong hospital or Elderly Welfare Center in Seoul. They received the T&C test and MMSE K examination. Sensitivity, specificity, negative predictive value, and Pearson' Correlation coefficient were calculated using standard formulas. RESULTS: The T&C had a sensitivity of 50%, a specificity of 88 %, a positive predictive value of 69%, a negative predictive value of 77 %, respectably. when timed cutpoints were added, The T&C test had a sensitivity of 95%, specificity of 83 %, a positive predictive value of 75%, a negative predictive value of 97 %. respectibaly. CONCLUSION: The Time and Change(T&C) tests can be an effective, simple and performance based tool to recognize dementia. Further validation with a representative elderly sample is needed to establish screening value in primary care or community populations.

One case of bezafibrate-induced myopathy was experienced and presente with a brief review of literatures. A 80-year-old woman with diabetes mellitus developed generalized myalgia and chest tightness 2 days before admission. The patient was treated with bezafibrate (800mg/day) for the previous 3 months. Serum creatine kinase, LDH and AST were markedly increased. Muscle biopsy revealed type 2 fiber atrophy. Withdrawal of the drug under the impression of bezafibrate-induced myopathy was followed by rapid clinical improvement.

PURPOSE: This study aimed to assess the reference values and factors influencing blood lead levels among Korean adolescents. METHODS: The study population consisted of 1,585 adolescents (801 males, 784 females; aged 10-19 years) who participated in the Korea National Health and Nutrition Examination Survey 2010-2013. We analyzed blood lead concentrations in relation to demographic/lifestyle characteristics for all participants. "Reference values" of blood lead levels were calculated as the upper limit of the 95% confidence interval of the 95th percentile. RESULTS: The average "reference value" for blood lead concentrations among Korean adolescents was 2.25 µg/dL (2.49 µg/dL for males, 2.07 µg/dL for females), and the geometric mean of the blood lead concentrations was 1.34 µg/dL. Males had higher blood lead concentrations than females (male, 1.48 µg/dL; female, 1.19 µg/dL; P<0.001). Elementary school students had higher blood lead concentrations than junior and senior high school students (1.44 µg/dL vs. 1.31 µg/dL, P<0.001). Participants living in detached houses had higher blood lead concentrations than those living in apartments (P<0.001) and current smokers had higher concentrations than nonsmokers or participants with secondhand smoke exposure (P<0.05). Additionally, participants with excessive alcohol consumption had higher levels than non-drinkers (P<0.001). CONCLUSION: This study provides national reference data on blood lead concentrations stratified by demographic and lifestyle factors among Korean adolescents. Further studies are needed to elucidate the relationship between increased lead exposure and demographic factors including type of housing.
