Relation between Human Chorionic Gonadotropin and Thyroid Hormones in Preeclampsia
Aim: Alterations in thyroid function with a simultaneous increase of hCG in some pregnancy diseases have been reported. However, the relationship between thyroid hormones and hCG during preeclampsia is not yet evaluated. In this study we determined serum levels of hCG, TSH, free T3 (fT3) and free T4 (fT4) in normal pregnant woman and in patients with preeclampsia and evaluated the correlation b...
متن کاملThyroid-stimulating activity and chorionic gonadotropin.
The nature of the substance with thyroid-stimulating activity (TSA) present in human chorionic gonadotropin (hCG) prepared from pregnancy urine was investigated. In the mouse thyrotropin bioassay, the characteristic maximum of blood radioactivity obtained with the TSA in hCG preparations occurred after that obtained with pituitary thyrotropin (hTSH) but before that obtained with long-acting thy...
متن کاملTreatment with human chorionic gonadotropin and risk of breast cancer.
Studies of the induction of mammary tumors by 7,12-dimethylbenz(a)anthracene in a rat model show that human chorionic gonadotropin (hCG) administration reduces tumor incidence in a manner comparable to that of a completed pregnancy. On the basis of their studies, Russo and Russo (Cancer Epidemiol., Biomarkers & Prev., 3: 353-364, 1994) have proposed that hCG treatment of young nulliparous women...
متن کاملTreatment with Human Chorionic Gonadotropin and Risk of Breast Cancer1
Studies of the induction of mammary tumors by 7,12dimethlybenz(a)anthracene in a rat model show that human chorionic gonadotropin (hCG) administration reduces tumor incidence in a manner comparable to that of a completed pregnancy. On the basis of their studies, Russo and Russo (Cancer Epidemiol., Biomarkers & Prey., 3: 353-3M, 1994) have proposed that hCG treatment of young nulliparous women w...
متن کاملAsialoagalacto-human chorionic gonadotropin, a carbohydrate-modified variant of human chorionic gonadotropin, antagonizes the stimulatory actions of bovine thyroid-stimulating hormone on thyroid function and HLA-DR expression in human thyroid in vitro and in vivo.
The concept of using thyroid-stimulating hormone (TSH) receptor antagonists in the management of Graves' disease is intriguing. Therefore, we investigated a TSH receptor antagonist derived from human chorionic gonadotropin (hCG) with respect to TSH receptor binding, adenylate cyclase activity, thyroid hormone release, and HLA class II antigen expression in vitro and in an in vivo model. A varia...
