Lack of release of human chorionic gonadotropin by gonadotropin-releasing hormone.
The effects of either single injection or continuous infusion of synthetic Gn-RH on plasma hCG levels were studied in 5 pregnant women (14-38 week gestation). No definite increase of hCG level was seen in all the cases studied. In view of large dosages of Gn-RH used in this study in comparison with its minimum effective dose for the pituitary gonadotropin release, Gn-RH seems unlikely to play a...
متن کاملBeta-Human Chorionic Gonadotropin (βHCG) Levels in Pre-eclamptic and Normotensive Pregnant Women
Background: Pre-eclampsia along with bleeding and infection constitute a triad that is a major cause of maternal mortality. Many factors have been recognized which can help us to determine the severity of the disease and early diagnosis of it. Since throphoblastic disorder is one of the etiological causes of pre-eclampsia, we decided to measure the level of β-hCG as a marker of detecting the ac...
متن کاملQuantification of Human Chorionic Gonadotropin by Bovine Serum Albumin Nanoparticles
Background and Aims: Some nanoparticles can be used in immunoassays to increase sensitivity. This study aimed to evaluate a novel nano-immunoassay based on bovine serum albumin nanoparticles (BSA NPs). Materials and methods: At first, the nanostructure was synthesized, and then applied as a tag in the nano-immunoassay. Then the concentration of β-subunit of human chorionic gonadotropin ...
متن کاملReproductive responses of dairy cows with ovarian cysts to simultaneous human chorionic gonadotropin or gonadotropin-releasing hormone and cloprostenol compared to gonadotropin-releasing hormone alone treatment.
AIM Bovine ovarian cysts are a common cause of economic loss in modern dairy herds. The objective of the present study was to evaluate the reproductive responses to three protocols using hCG, GnRH and cloprostenol when the definite diagnosis of the type of ovarian cyst is/is not possible in dairy cows. MATERIALS AND METHODS A total of 144 lactating dairy cows with ovarian cysts were divided i...
متن کاملInhibin and activin modulate the release of gonadotropin-releasing hormone, human chorionic gonadotropin, and progesterone from cultured human placental cells.
Although it is clear that human chorionic gonadotropin (hCG) and progesterone play fundamental roles in pregnancy, the regulation of placental production of these hormones remains to be defined. Recent evidence suggests that the human placenta expresses proteins related to inhibin (alpha beta subunits) or activin (beta beta subunits). Inhibin and activin (follicle-stimulating hormone-releasing ...
