Human chorionic gonadotrophin: comparative studies of ovarian uptake in mammals.
-l. The localization of radiolabeled human chorionic gonadotrophin (~2SI-HCG) was studied in a number of commonly used mammalian animal models. 2. The ovary proved to be the target organ for ~25I-HCG in all animals studied. 3. The optimum time for the localization of HCG in the ovary varied in all the mammals extending from 1.5 to 4 hr. 4. HCG is apparently used in the target cell for only a br...
متن کاملPreliminary therapeutic and localization studies with human chorionic gonadotrophin.
Studies in both patients and mice have been carried out using heterologous antibody directed at secreted products of tumors. In preliminary therapeutic studies in patients with drug-resistant choriocarcinoma and malignant teratoma, heterologous anti-human chorionic gonadotrophin (HCG) and anti-alpha-fetoprotein have been combined with continued cytotoxic chemotherapy. The results to date, altho...
متن کاملEffect of gonadotrophin-releasing hormone aned human chorionic gonadotrophin on the response of the ewe to pregnant mare serum gonadotrophin.
An experiment was conducted to determine whether gonadotrophin-releasing hormone (Gn-RH) or HCG would reduce the proportion of unruptured follicles in the Galway ewe following a high superovulating dose of PMSG given in conjunction with a progestagen to synchronize oestrus. Forty-four Galway ewes aged 1\m=1/2\to 5 years (average wt 64\m=.\7kg) were treated with intravaginal pessaries impregnate...
متن کاملUrinary chorionic gonadotrophin determination.
Successful laboratory tests for early pregnancy utilize the endogenous production and excretion of chorionic gonadotrophin (CG). There is wide variation in sensitivity and specificity of various biological and commercially available immunochemical methods for determining urinary CC levels. Normal values for immunochemically reactive CC during the first trimester of pregnancy are given. Serial d...
متن کاملThe effect of equine chorionic gonadotrophin (ecg) injection combined with prostaglandin F2α (pGF2α) and gonadotrophin releasing hormone (GnRH) treatment on reproductive performance of Zandi ewes during non-breeding season
In this study, we aimed to investigate reproductive performance in estrus-induced Zandi ewes treated with equine chorionic gonadotrophin (eCG) injection in combination with prostaglandin F2α (PGF2α)and gonadotrophin releasing hormone (GnRH) during non-breeding season. The estrous cycle was synchronized using controlled internal drug release (CIDR) for 12 days. The ewes were randomly assigned to...
