Effect of bromodichloromethane on chorionic gonadotrophin secretion by human placental trophoblast cultures.
Bromodichloromethane (BDCM) is a trihalomethane found in drinking water as a by-product of disinfection processes. BDCM is hepatotoxic and nephrotoxic in rodents and has been reported to cause strain-specific full-litter resorption in F344 rats during the luteinizing hormone-dependent phase of pregnancy. In humans, epidemiological studies suggest an association between exposure to BDCM in drink...
متن کاملAnalysis of chorionic gonadotrophin secreted by cultured human blastocysts.
Embryos produced in an in-vitro fertilization (IVF) programme, but which were unsuitable for transfer to patients because they originated from one (1PN) or three pronuclear (3PN) oocytes or because they originated from two pronuclear (2PN) oocytes but cleaved normally, were maintained in tissue culture. The embryos that progressed to blastocytes were cultured to day 14 of development in order t...
متن کاملHuman chorionic gonadotrophin as an indicator of persistent ges-tational trophoblastic neoplasia
Background : Gestational trophoblastic neoplasia (GTN) disease is excessive and inappropriate proliferation of trophoblast after termination of the pregnancy. Many attempts have been made to improve follow-up procedures, but no studies have evaluated Human Chorionic Gonadotrophin (HCG) as a post treatment indicator. Thus we aimed to know β-HCG variability in post treatment pregnancies. Meth...
متن کاملUp-regulation of placental leptin by human chorionic gonadotropin.
Leptin, the 16,000 molecular weight protein product of the obese gene, was originally considered as an adipocyte-derived signaling molecule for the central control of metabolism. However, leptin has been suggested to be involved in other functions during pregnancy, particularly in placenta, in which it was found to be expressed. In the present work, we have found that recombinant human chorioni...
متن کاملDirect binding of radioiodinated human chorionic gonadotrophin to frozen sections of rat testis.
Most published work on the binding of gonadotrophins to testicular tissue has been based on a biochemical approach and whole organs, homogenates or subcellular fractions have been used. Some studies have been concluded on interstitial tissue and/or seminiferous tubules separated from each other by microdissection after the method of Christensen & Mason (1965). Binding of radioiodinated HCG to s...
