The aim of this study was to determine whether the current regimen of dexamethasone administration to induce fetal lung maturation affected the circulating concentrations of placental hormone. A standard regimen of dexamethasone that comprised two doses of 12-mg intramuscular injections, 12 h apart was administered to 12 pregnant women to promote fetal lung maturation in anticipation of prematu...

A puberal change in the secretory pattern of androgen was investigated in the rat. Using immature and adult rats which received an acute human chorionic gonadotrophin(HCG) stimulation, androstenedione and testosterone were measured both in the testicular venous blood(TVB) and in the testis by means of gaschromatography after preliminary separation by paperchromatography. In contrast to the adul...

Spontaneous forms of the ovarian hyperstimulation syndrome (sOHSS) are nearly always reported between 8 and 14 weeks of pregnancy and also with follicle-stimulating hormone (FSH) producing pituitary adenoma. The syndrome has been previously reported in rare instances of increased production of human chorionic gonadotrophin (hCG) such as multiple pregnancies, hydatiforme mole, polycystic ovary d...

BACKGROUND Our aim was to evaluate whether extending the interval between human chorionic gonadotrophin (hCG) priming and immature oocyte retrieval increases the oocyte maturation rate following in vitro maturation (IVM). METHODS This study was performed retrospectively. IVM was performed on 113 polycystic ovary syndrome patients (n = 120 cycles). Oocyte collection was performed either 35 h (...

Human chorionic gonadotropin (HCG) is an important tumor marker in the diagnosis and monitoring of treatment response childhood cancers such as germ cell tumors liver tumors. The effect chronic kidney disease (CKD) on increased HCG not a well-researched issue. elevation unknown cause only causes diagnostic confusion, but also economic loss by necessitating many unnecessary examinations.In curre...

It has been shown that immune cells, particularly macrophages, accumulate in the corpus luteum during luteolysis. This study aimed to investigate the effect of maternal recognition of pregnancy on the localization and numbers of macrophages in the human corpus luteum. Corpora lutea (n = 12) were obtained from normally cycling women at the time of hysterectomy and were dated on the basis of seri...

The present study was undertaken to investigate the effect of decidualization on superoxide dismutase (SOD) expression in human endometrial stromal cells (ESC). To induce decidualization, isolated ESC were incubated with medroxyprogesterone acetate (MPA, 10(-6) mol/l) and oestradiol (10(-8) mol/l) for 23 days. Insulin-like growth factor-binding protein-1 (IGFBP-1) was used as a marker of decidu...

Human chorionic gonadotropin (hCG) is useful in evaluating and monitoring early pregnancy as well as trophoblastic disease. Here we describe the management of women with elevated serum human chorionic gonadotropin in a case of a 51-year-old female who was unsuccessfully treated for ectopic pregnancy. She was subsequently diagnosed with pituitary hCG production, which should be considered as dif...

The role of macrophage migration inhibitory factor (MIF) in human ovarian function remains obscure. The aim of this study was to investigate how MIF was related to ovulation by quantitative analysis of serum, follicular fluid and culture medium of granulosa cells obtained from in-vitro fertilization (IVF) and embryo transfer patients. Serum MIF concentrations in ovarian stimulation cycles for I...

In a study of 130 first trimester cases of trisomy 21 and 959 controls we have shown that the median MoM for alpha-fetoprotein (AFP) is lower (0.82) and that for total human chorionic gonadotrophin (hCG) is higher (1.31) than in the control group. For AFP 15.3% of cases were below the 5th centile and for total hCG 19. 8% were above the 95th centile. The median shift observed for AFP and total h...
