Immunohistochemical Localization of Human Chorionic Gonadotropin
Through the use of immunohistochemical techniques, human chorionic gonadotropin has been localized to syncytiotrophoblastic cells of immature placenta, hydatidiform mole, chorioadenoma destruens, and choriocarcinoma. No gonadotropin has been detected in cytotrophoblast. Evidence is discussed which suggests that syncytiotrophoblast is the cell of origin of human chorionic gonadotropin. The obser...
متن کاملAn immunohistochemical study of keratin, carcinoembryonic antigen, human chorionic gonadotropin and alpha-fetoprotein in lung cancer.
Immunohistochemical staining utilizing a peroxidase-antiperoxidase (PAP) technique for keratin, carcinoembryonic antigen (CEA), human chorionic gonadotropin (HCG) and alpha-fetoprotein (AFP) was performed on paraffin sections from 72 cases of lung cancer obtained at autopsy. Positive reaction was shown in 44% of the cases for keratin, 77% for CEA, and 58% for HCG. AFP was positive in only one c...
متن کاملHuman Chorionic Gonadotropin
A highly active preparation of human chorionic gonadotropin has been obtained by simple methods of column chromatography on diethylaminoethyl Sephadex and Sephadex G-100. The preparation appeared homogeneous by disc and immunoelectrophoresis, ultracentrifugation, and end group analysis. It assayed at 12,000 i.u. per mg by the rat prostrate gland and accessory sex organ method. The ~20,~ value w...
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 کاملHuman chorionic gonadotropin (hCG) versus magnesium sulfate to arrest preterm
Introduction: Considering the high incidence of preterm labor and its known complications, and that human myometrium contains receptors for human chronic gonadotropin (hCG) and that hCG can inhibit myometrial contractions on vitro, made me study treating effects of hCG on preterm labor. This clinical trial study was carried out to compare the effect of hCG, and magnesium sulfate (mgso4) on pre...
