A case of a thirty-eight year old man with pseudohypoparathyroidism (PHP) type 1 associated with gonadotropin resistance and hypercalcitoninaemia was reported. The basal levels of the luteinizing hormone and follicle-stimulating hormone were elevated, and the responses to the luteinizing hormone-releasing hormone were exaggerated. The basal level of testosterone was normal, but the response to ...
We evaluated a new simplified quantitative method (Tandem Icon QSR; Hybritech) for choriogonadotropin (hCG), which could theoretically be performed in a ward or with outpatients. The method was compared with immunoradiometric (Bioclone Australia), chemiluminescent (Amerlite; Amersham), and immunoenzymometric assays (Stratus; Dade). We analyzed by each of the methods 104 serum samples from pregn...
Previous studies have favored a basic difference in the regulation of specialized protein production by cells derived from the usual tissue of origin (eutopic) and cancer cells derived from a tissue not normally producing the protein (ectopic). Thus N6,O2'-dibutyryl cyclic adenosine 3':5'-monophosphate was believed to stimulate only eutopic (but not ectopic) chorionic gonadotropin production, a...
Testicular germ cell tumors (TGCTs) represent the most common type of solid tumors among men aged 15 to 40 years. An increasing incidence has been recorded in developed countries. In clinical practice, TGCTs are classified as seminomas and non-seminomatous tumors. Non-seminomatous tumors often contain multiple different cell types and can be further sub-divided according to the histological and...
Choriocarcinoma is a curable malignancy that occurred approximately 50% after term pregnancies, and prognosis in this form of gestational trophoblastic Disease (GTD) is Poor. The earliest onset choriocarcinoma after term pregnancy in one study was reported 3 weeks after delivery, but in current study, choriocarcinoma was diagnosed 2 weeks after delivery. 28 years-old women gravidity 2, parity 2...
Treatment with colchicine or x-radiation of a human embryonal carcinoma of testicular origin, which has secreted a chorionic gonadotropin-like hormone in ~0 per cent of heterografted hosts, resulted in a 2 89 times increase in the incidence of chorionic gonadotropin-secreting tumors as determined in oophorectomized and hypophysectomized animals. Lines developed from three of the tumors treated ...
We studied the in vitro effect of dipyrone on the determination of free triiodothyronine (free T3), cortisol, progesterone, estradiol, carcinoembryonic antigen, human chorionic gonadotropin and alpha-fetoprotein measured with an immunoenzyme assay based on enhanced luminescence that uses peroxidase as label. We found significant interference from dipyrone (p < 0.01) in the determination of all ...
