This study was designed to investigate the relationship between insulin resistance and obesity in the pathogenesis of polycystic ovarian syndrome(PCO). Twenty-two women with PCO, of whom thirteen were non-obese with body mass index(BMI, kg/$m^2$) of <25 and nine were obese with BMI${\geq}$25 were studied. Eight non-obese control women and seven obese control women were studied. Serum concentrations of testosterone, lutenizing hormone(LH)/follicle-stimulating hormone(FSH) ratio, and insulin-like growth factor I (IGF-I) were found to be significantly higher(P<0.05) in PCO women compared with control women, which clearly is not related to obesity. Serum glucose, insulin, and C-peptide levels were measured during a 2-hour oral glucose tolerance test(OGTT). Non-obese and obese women with PCO both(P<0.05) compared with control women demonstrated significant hyperinsulinemia after OGTT. The degree of hyperinsulinemia was found to be significantly higher in the obese women with PCO compared with the non-obese women with PCO. We concluded that obesity may contribute to hyperinsulinemia, however may not playa central role in the pathogenesis of PCO.

A numerical and experimental analysis on the membrane humidifier for PEM(Proton Exchange Membrane) fuel cell is presented in this work. Some parameters such as flow channel width, height and number are considered and studied by applying CFD analysis. From these results, the shape in the humidifier is optimized and tested by experiment. Nafion 115 is adopted as membrane material and the number of layers is 50. The conditions in residential fuel cell are applied to the experimental conditions. From the experiment, approach temperature 7.4 ℃, consuming power 9.1 W and R.H in the outlet of the humidifier 100% are obtained.

CCS (carbon capture and storage) is recently issued due to green house effect and many studies have been conducted. As one of CO2 sequestration, CO2 is stored in deep and stable underground. In this paper, simulation of CO2 storage tank is conducted for CO2 injection system. In addition to simulation, experimental study for super critical condition of CO2 also is conducted. Storage tank is modeled and simulated by simulink program. For experiment, several components such as heat exchanger, injection pump, heater and storage tank are installed and operated. Liquid CO2 is flowed into pump from storage tank and super critical CO2 injection can be estimated.

The role of estrogen in calcium metabolism has not been well documented. To further investigate the effects of endogenous estrogen on the calcium regulating hormones in women, we correlated the changes of estrogen level with those of calcium regulating hormones during ovulation induction in 12 hypogonadal and 8 normally menstruating women. During ovulation induction, the serum leveles of estradiol rose from 40.0 to 831.0pg/ml. There were no significant changes in the serum leveles of total calcium, inorganic phosphorus, parathyroid hormone, calcitonin. However, 1, $25-(OH)_2D_3$ rose significantly from 31.0 to 47.2pg.ml as the endogenous $E_2$ increaed (p<0.005).
자궁근종시 LHRH agonist (D-Trp6-LHRH) 치료에 따른 근종세포내 미세구조의 변화

Long-term administration of luteinizing hormone-releasing hormone(LHRH) agonists, through a process of pituitary desensitization and down-regulation of receptors, inhibits the secretion of gonadotropin and sex-steroids and induces a reversible suppression of gonadal activity. This approach can be used as an effective endocrine therapy for some hormone-dependent tumors. We have used D-Trp6-LHRH, a long acting LHRH agonist, for the treatment of eleven patients with uterine leiomyomas, thereafter myomectomy was performed in seven cases and observed the ultrastructural changes of leiomyoma with an electron microscope. The use of LHRH agonist may be effective in reducing the size of a myoma considerably by primarily inducing medical hypophysectomy and would allow easier surgical removal. Electron microscopic findings of myoma cells after the use of LHRH agonist included the following: loss of cristae and swelling nuclear chromatin, perinuclear vacuolation in cytoplasm. Bone mineral density was slightly decreased, however, the difference was not statistically significant.

A 27-year-old pregnant woman who had one son with mental and growh retardation and dysmorphic features, was referred for genetic counselling. Cytogenetic investigations revealed 4/22 translocation in the mother(46, XX, t(4;22)(p14;P11)), partial trisomy 4p in son(46, XY, -22, +der(22), t(4;22)(p14;p11)mat). The father had normal karyotype. Amniocentesis and chorionic villi sampling were performed in 3 successive pregnancies. The karyotypes of fetus in 3rd, 4th pregnancies by amniocentesis were 46, XX, t(4;22)(p14;p11) and 46, XX, t(4;22) (p14;p11), and the karyotype of fetus in 5th pregnancy by chorionic villi sampling was found to be 46, XX, -22, +der(22) t(4;22)(p14;p11)mat. We report 3 succesive prenatally diagnosed familial partial trisomy 4p and 4/22 translocation of maternal origin with review of literature.

자궁내막이 생체내 insulin-like growth factor binding protein-1(IGFBP-1)의 혈중치를 유지하는데 얼마나 관여하는지를 평가해 보았다. Immunoreactive IGFBP-1의 혈중치의 측정을 위하여, 월경과다를 주소로 내원한 19명의 환자를 대상으로, gynecologic resectoscopy로 자궁내막 박리를 시행하였다. 자궁내막 박리를 시행한 환자의 혈중 IGFBP-1의 평균치는, 시행전과 비교할 때 감소된 소견을 보였으며, 월경주기와는 상관관계가 없었다. 이러한 소견으로 보아, 자궁내막이 혈중 IGFBP-1의 생성원의 하나로 사료되었다.
