The results investigated on the fauna and ecology of spiders as natural enemy at the farmland in Sain area is summarized as follows : 936 individuals of collected spiders during investigation are identified 14 families, 40 genera and 69 species. The dominant families are Araneidae(45.6%), Agelenidae(12.8%), Lycosidae(9.4%) and Thomisidae(6.6%). The dominant genera are Araneus(29.9%), Agelena(12.8%), Pardosa(9.2%) and Achaearanea(5.5%). The dominant species are Araneus cornutus(30.1%), Agelena limbata(11%), Pardosa astrigera(8.7%) and Achaearanea tepidariorum(5.3%). Hitherto, 9 species of the genus Achaearanea have been reported from Korea. Among collected spiders, Achaearanea oculiprominentis is identified as unrecorded species, so the genus Achaearanea become 10 species from Korea. Webbing spiedrs(73.4%) are more abundant and influencable on spider fauna than wandering spiders(26.6).

Objective: Ultrasonographic screening between 9 and 13 weeks for fetal structural abnormalities using transvaginal sonography in unselected population. Visualization of detailed fetal anatomy in the first trimester has improved as a result of technological progress in ultrasound machines and the introduction of transvaginal sonography(TVS). Our study aims to evaluate the accuracy of TVS as a screening tool for detecting fetal malformations in a nonselected population of pregnant women. For this purpose we compared the results obtained by using second trimesster TA scanning with those obtained using TVS at 9-14 weeks' gestation. Methods: From March 2001 to February 2003, 620 unselected consecutive pregnant women were recruited at their initial visit at Soonchunhyang university hospital, department of obstetrics and gynecology and offered a TVS scan at the average gestational age of 9-13 weeks in addition to the TA screening usually performed between 22-26 weeks. To fulfill the technical requirements of a screening test, ultrasonographic examinations were performed by skillful operators with different degrees of experienced using adequate instruments Aloka SSD 5500 (Aloka Co. Ltd., Tokyo, Japan) provided with either a 3.5-5MHz TA probe or a 5-7.5MHZ TV probe) in a fixed scanning time of maximum 30 min, generally considered sufficient for a complete fetal anatomic survey. Results: During the study period we found in our unselected population an overall prevalence of target abnormalities of 2.2%(24 malformed fetuses out of 600 screened). In the fetuses examined by TVS, 16 abnormalities were detected whereas 8 were not; of these, 6 were detected at transabdominal rescreening at 22-26 weeks and the remaining 2 were observed after birth. A nuchal region abnormality was the most frequent type of malformation detected in the early scan, including six cases of nuchal edema, two cases of cystic hygroma associated with hygroma associated with hydrops, three cases of hydronephrosis, one case of fetal neck teratoma, one case of cleft lip. Conclusion: This study has demonstrated the potential of screening a low risk population for fetal abnormalities at 9-13 weeks of gestation using transvaginal sonography and rescreened via transabdominal sonography at 22-26 weeks. Larger studies are required to establish the clinical value of the first trimester scan.

Purpose: We have evaluated the compliance of hormone replacement therapy. Method: There are 185 climacteric women who are divided into three groups (Group I, Group II, Group III). Group I is given conjugated equine estrogen(CEE, 0.625mg, day 1-30) plus medroxyprogesterone acetate(MPA, 5mg, day 1-12). Group II is given conjugated equine estrogen (CEE, 0.625mg, day 1-30) plus medroxyprogesterone acetate (MPA, 2.5mg, day 1-30), Group III is given only conjugated equine estrogen(CEE, 0.625mg, day 1-30). Results: 1) The compliance rate of hormone replacement therapy during three months is 77.9% including each Group I : 77.7%, Group Ⅱ : 76.1%, Group Ⅲ :80.4%. 2) The compliance rate of hormone replacement therapy during six months is 60.7% including each Group Ⅰ:52.9%, Group Ⅱ: 56.4%, Group Ⅲ: 79.5%. 3) The compliance rate of hormone replacement therapy during nine months is 49.7% including each Group Ⅰ: 45.5%, Group Ⅱ:41.7%, Group Ⅲ: 64.3%. 4) The compliance rate of hormone replacement therapy during a year is 44.4% including each Group Ⅰ: 40.2%, Group Ⅱ:35.3%, Group Ⅲ: 59.5%. Conclusion : It is vital that we maximize compliance if patients are to receive the full benefits from hormone replacement therapy. We think that physicians who prescribe hormone replacement therapy for climacteric women should enough explain the purpose, risks, and side effect of treatment for maximizing compliance of hormone replacement therapy.

Cardiovascular disease is one of the most common cause of death in postmenopausal women. After the onset of menopause, the risk of cardiovascular disease is increased. Several risk factors of cardiovascular disease are well known to us. Among the risk factors, the changes of lipid profiles are roles for cardiovascular disease. Estrogen appears to protect the development of cardiovascular disease, by several mechanism. Especially the protective effect is believed to be mediated by the changes of lipid profiles. Decreased high-density lipoprotein (HDL)-cholesterol and increased low density lipoprotein (LDL)-cholesterol are important factors for development of cardiovascular disease. The purpose of this study was to evaluate the effect of hormone replacement therapy on the lipid profiles to include total cholesterol (TC), high density lipoprotein(HDL)-cholesterol, low density lipoprotein(LDL)-cholesterol, and triglycerides. We measured lipid profiles in 31 postmenopausal women and gave each conjugated equine estrogen (CEE, 0.625mg, day 1-30) plus medroxyprogesterone acetate (MPA, 5mg, day 1-12) for 12months. The levels of serum TC, LDL-cholesterol, and triglycerides were decreased significantly (p<0.05) and HDL-cholesterol was increased significantly (p<0.05) after 12months of hormone replacement therapy. These data suggest that hormone replacement therapy appears to protect agianst the development of cardiovascular disease by the changes of lipid profiles.

Identification and characterization of peroxisome proliferator response element in the mouse GLUT2 promoter

In the present study, we show that the expression of type 2 glucose transporter isoform (GLUT2) could be regulated by PPAR-γ in the liver. Rosiglitazone, PPAR-γ agonist, activated the GLUT2 mRNA level in the primary cultured hepatocytes and Alexander cells, when these cells were transfected with PPAR-γ/RXR-α. We have localized the peroxisome proliferator response element in the mouse GLUT2 promoter by serial deletion studies and site-directed mutagenesis. Chromatin immunoprecipitation assay using ob/ob mice also showed that PPAR-γ rather than PPAR-α binds to the -197/-184 region of GLUT2 promoter. Taken together, liver GLUT2 may be a direct target of PPAR-γ ligand contributing to glucose transport into liver in a condition when PAPR-γ expression is increased as in type 2 diabetes or in severe obesity.

Glucose-stimulated upregulation of GLUT2 gene is mediated by sterol response element-binding protein-1c in the hepatocytes.

<P>GLUT2 is mainly expressed in the liver, beta-cells of the pancreas, and the basolateral membrane of kidney proximal tubules and plays an important role in glucose homeostasis in living organisms. The transcription of the GLUT2 gene is known to be upregulated in the liver during postprandial hyperglycemic states or in type 2 diabetes. However, a molecular mechanism by which glucose activates GLUT2 gene expression is not known. In this study, we report evidence that sterol response element-binding protein (SREBP)-1c plays a key role in glucose-stimulated GLUT2 gene expression. The GLUT2 promoter reporter is activated by SREBP-1c, and the activation is inhibited by a dominant-negative form of SREBP-1c (SREBP-1c DN). Adenoviral expression of SREBP-1c DN suppressed glucose-stimulated GLUT2 mRNA level in primary hepatocytes. An electrophoretic mobility shift assay and mutational analysis of the GLUT2 promoter revealed that SREBP-1c binds to the -84/-76 region of the GLUT2 promoter. Chromatin immunoprecipitation revealed that the binding of SREBP-1c to the -84/-76 region was increased by glucose concentration in a dose-dependent manner. These results indicate that SREBP-1c mediates glucose-stimulated GLUT2 gene expression in hepatocytes.</P>
