We detected pregnancy related new molecule, human chorionic gonadotropin related protein (hCGRP) in the urine of a pregnant women by using a monoclonal antibody against the human chorionic gonadotropin (hCG). This study examined the effectiveness of urinary hCGRP quantification in diagnosing ectopic pregnancy. This study included 40 normal pregnant women and 25 patients with ectopic pregnancy. ...

background: human chorionic gonadotropin (hcg) has been used as a replacement for the mid-cycle luteinizing hormone (lh) surge for several years. the recent arrival of recombinant dna technology has made recombinant hcg (rhcg) accessible. objective: to assess efficacy of rhcg compared to urinary hcg (uhcg) for triggering of ovulation and induction of final oocyte maturation in assisted reproduc...

Background: Urinary human chorionic gonadotropin is the most widely used medicine for ovulation in ovarian stimulation cycles. Recently however, recombinant HCG has also become commercially available. This study presents compare the use of recombinant hCG with urinary hCG during controlled ovarian hyperstimulation and intra uterine insemination (COH-IUI ) cycles Materials and Methods: This is s...

Human chorionic gonadotropin (hCG) is a highly specific tumor marker or trophoblastic neoplasms. Also in patients with non-trophoblastic tumors, hCG beta-related material has been frequently demonstrated in their urine. This material was termed beta-core fragment (beta-CF) since it is recognized by hCG beta-core directed antisera but not by hCG beta-carboxyterminal peptide (CTP) directed antise...

OBJECTIVE To differentiate between benign and malignant hyperparathyroidism on the basis of excretion of HCG and its malignant isoforms in urine. MATERIALS AND METHODS This hospital based study was carried out using data retrieved from the register maintained in Manipal Teaching Hospital from 1st January, 2008 and 31st August, 2012. The variables collected were urinary HCG and HCG malignant i...

The present study is designed to elucidate certain biological characteristics of urinary chorionic gonadotropin and to see what differences could be demonstrated between HCG in normal pregnancy and in the trophoblastic diseases. We have attempted the biological characterization of HCG using crude HCG and the purified HCG (12 ,000 I.U./mg) by zone electrophoresis on starch grain and chromatograp...

In biological fluids, hCG and its free alpha- (hCG alpha) and beta-subunits (hCG beta), occur in multiple forms. These various forms differ at the molecular level primarily in glycosylation, but also differ in protein backbone modifications corresponding to the urinary low molecular weight fragment of the hCG beta-subunit (beta-core fragment). This microheterogeneous nature can be demonstrated ...

Trophoblastic diseases are mainly hydatidiform mole and choriocarcinoma, where the latter is usually the sequela of molar pregnancy and malignant systemic disease with general metastases destructing various tissues and organs till she die. High level urinary hCG, real-time B-mode and color Doppler imaging detect hydatidiform mole in early gestation, postmolar persistent trophoblastic disease is...

Tumor hypoxia modifies the efficacy of conventional anticancer therapy and promotes malignant tumor progression. Human chorionic gonadotropin (hCG) is a glycoprotein secreted during pregnancy that has been used to monitor tumor burden in xenografts engineered to express this marker. We adapted this approach to use urinary beta-hCG as a secreted reporter protein for tumor hypoxia. We used a hypo...

(urinary creatinine concentration). Because most of the serum results referred to were below or close to the detection limits of the kits, the urine results would be expected to he negative with the qualitative tests. The NovoClone HCG kit measures intact HCG as well as free 13-chains. The Delfia kit from Pharmacia measures the intact HCG molecule only. This difference might explain the only re...
