[영문] The purpose of this study was to investigate the associations between phenotypic characteristics including the stature and the change of body mass index(BMI) and the prevalence of gestational diabetes mellitus (GDM) in Korean women. The study included a total of 1862 pregnant women who were screened for GDM at the Pundang CHA hospital from 1998 to 2000. Twenty-nine pregnant women known to have diabetes mellitus, and 122 women who were not confirmed for GDM were excluded in statistical analysis. Data were extracted from hospital information system (HIS) and analyzed by ANOVA. The effect of phenotypic characteristics on the prevalence of GDM was evaluated by multiple logistic regression analysis. Multiple logistic regression analysis revealed that age (p<0.05), BMI (p<0.001), weight gain (p<0.001), and genetic factor (p<0.001) were significantly associated with the prevalence of GDM. However, maternal height was not statistically significant When it was anaiysed as a continuous or discrete variable. The odds ratio for GDM according to age and BMI were 1.1 and 1.141 respectively. Furthermore, women with GDM were older and heavier than the normal oral glucose tolerance test group. The pregnant women with parental history of diabetes mellitus had the higher prevalence of GDM. This finding is very similar to the other previous studies. We revailed that odds ratio was 3.175. However, weight gain of pregnant women was inversely related with the prevalence of GDM. We suspected that the pregnant women with GDM might put themselves on restricted diets during the pregnant period after the confirm test. In conclusion, short stature appears to be not associated with GDM in Korean women born after 1960.ope

    Objective: Subfertility associated with polycystic ovarian syndrome (PCOS) mainly originates from oligo/anovulation; however, factors related to blastocyst implantation and maintenance of pregnancy may also contribute. Although roles for insulin resistance and androgen excess have been suggested in the pathogenesis of PCOS-associated implantation failure, a comprehensive investigation of the consequences of PCOS on endometrial homeostasis and pathophysiology has not been performed. In this study, I investigated whether insulin sensitivity and glucose metabolism in the endometria of patients with PCOS are intrinsically altered. I also examined whether hyperandrogenic milieu affect glucose metabolism and the global gene expression patterns in cultured human endometrial stromal cells (hESCs), and studied the influence of hyperandrogenic conditions on facilitated glucose transporters (GLUTs) expression during in vitro decidualization of hESCs. Design: Experimental study involved the use of human endometrial tissues and a human endometrial cell line. Materials and Methods: Seven healthy women with regular menstrual cycles and 16 patients with PCOS were recruited for this study. Endometrial samples were obtained from the corpus of the uteri under sterile conditions. Control endometria were biopsied in the early proliferative phase, due to morphological and physiological similarities to those of patients with PCOS. Reverse transcription polymerase chain reaction (RT-PCR), real-time RT-PCR, and western blot analysis were performed to examine the levels of proteins involved in insulin signaling and glucose metabolism. To mimic hyperandrogenism and hyperinsulinemia in patients with PCOS in vitro, hESCs were treated with 1, 10, or 100 ΞΌM dihydrotestosterone (DHT) for 3 to 9 days and 10 nM insulin for 8 hours, respectively. In vitro decidualization was induced in hESCs by culture with 0.5 mM cAMP and 1 ΞΌM medroxyprogesterone 17-acetate for 1 to 9 days. Messenger RNA (mRNA) microarray experiments were performed with hESCs treated with 10 ΞΌM DHT, and data were analyzed using Gene Set Enrichment Analysis (GSEA). Results: In the endometria of patients with PCOS, GLUT1, GLUT12, insulin receptor (IR), and insulin receptor substrate (IRS) levels were significantly increased. However, no differences in expression were observed between the endometria of obese and lean patients with PCOS. Notably, GLUT4 mRNA was not detected in the endometria of patients with PCOS nor control subjects. Levels of phosphorylated IRS1 (p-IRS1) and phosphorylated Akt (p-Akt) were up-regulated in the lysates of both insulin- and androgen-treated hESCs. In addition, DHT treatment up-regulated the levels of GLUT1 and GLUT12 in cultured hESCs, suggesting that hyperandrogenic conditions affect glucose transport and/or metabolism. This notion was supported by mRNA microarray experiments, which further demonstrated that glucose transport and/or metabolism was dysregulated in hESCs by DHT treatment. During in vitro decidualization, the expression levels of GLUT1, 8, and 12 gradually increased. Of note, protein and mRNA levels of GLUT1 and 12 were decreased when decidualizing hESCs were treated with DHT, although these changes were not statistically significant. Conclusion: Hyperandrogenic milieu up-regulated the adaptor protein of insulin signaling as well as GLUTs in the endometria of patients with PCOS. Messenger RNA microarray experiments revealed androgen-induced dysregulation of glucose transport and/or metabolism in human endometrium. During decidualization, hyperandrogenic conditions down-regulated the expression of GLUTs, possibly causing impaired uterine receptivity.openλ°•

[영문] Many prospective studies have now confirmed the predictive value of plasma fibrinogen levels for vascular diseases, including ischemic heart disease. Several polymorphisms of the Ξ²fibrinogen gene including Haeβ…’ polymorphism in the promotor region of the gene and Bclβ…  polymorphism in its downstream region have been investigated in relation to plasma fibrinogen levels. But, studies of the possible associations between these polymorphisms and plasma fibrinogen concentrations in the Korean population have not been carried out. For this study, the blood samples for DNA were collected from 109 healthy Koreans who have no relationship by blood(67 males and 42 females) in due consideration of some other factors such as gender, age, and smoking status. Four polymorphisms of the Ξ²fibrinogen gene that consist of Haeβ…’, Aluβ… , Mnlβ… , and Bclβ…  restriction fragment length polymorphisms (RFLPs) were investigated to examine the associations between RFLPs and plasma fibrinogen levels. The investigation into the RFLPs were made by polymerase chain reaction and enzyme digestion. The alleles with the restriction site and the non-cleavable alleles were designated H^^1 and H^^2 for the Haeβ…’ polymorphism, M^^l and M^^2 for Mnlβ…  Polymorphism, A^^l and A^^2 for the Aluβ…  polymorphism, and B^^2 and B^^l for the Bclβ…  polymorphism, respectively. The results were as follows: 1. Genotype H1H1 and H1H2 in Haeβ…’ RFLPs were detected from 69(61.5%) and 40(38.5%) persons among the above 109 control subjects respectively. Genotype M^^1 M^^1 and M^^1 M^^2 in Mnlβ…  RFLPs from 70(64.2%) and 39(35.8%) persons respectively. Genotype A^^1 A^^1 and A^^1 A^^2 in Aluβ…  RFLPs from 69(61.5%) and 40(36.7%) persons respectively. Among 95 control subjects, genotype B^^1 B^^1 and B^^1 B^^2 in Bclβ…  RFLPs were shown in 70(73.7%) and 25(26.3%) persons respectively. The Haeβ…’, Aluβ… , Mnlβ…  RFLPs were in tight linkage disequilibrium, while Bclβ…  RFLPs not being in it. 2. The significant associations between Haeβ…’, Aluβ… , Mnlβ…  RFLPs(H^^1 H^^2, M^^1 M^^2, A^^1 A^^2) and plasma fibrinogen were ascertained in both aged people(β‰₯ 50 years) and smokers, whereas the associations between Bclβ…  RFLPs and plasma fibrinogen were absent showing no connection with age or smoking status. 3. Plasma fibrinogen concentrations were significantly higher in the old ages(β‰₯ 50 years) than in the younger ages(≀ 49 years) in male, and also higher in smokers than in nonsmokers. In conclusion, genetic polymorphisms(H^^1 H^^1, M^^1 M^^2, A^^1 A^^2) of the Ξ²fibrinogen gene are associated and increased with plasma fibrinogen levels, especially in aged people and in smokers. These findings suggest that variation at the fibrinogen gene locus may contribute to the differences in plasma fibrinogen level. Considering that plasma fibrinogen is a risk factor for ischemic heart disease, stroke and peripheral arterial disease, it seems to be certain that these genotype polymorphisms have the predictive values for these vascular diseases in Koreans. Further studies to confirm this possibility are highly expected,restrictio
