Objective To compare efficacy and safety of two commercial urinary human chorionic gonadotrophin preparations(profasi(r) and pregnyl(r)) in controlled ovarian stimulation.

To purify the human chorionic gonadotropin (hCG) CP12 expressed in E.

In terms of related study and literature,we carried out review on exploring the research progress that evaluate human chorionic gonadotropin levels during the second and third trimester singleton pregnancy,and pointed out that the changes of HCG levels may predict and diagnose all kinds abnormal outcome of pregnancy.

Objective:To study the effects of insulin-like growth factor-I(IGF-I)and human chorionic gonadotropin(hCG)on expressions of glucose transporters(GLUT)gene and testosterone production in adult rat Leydig cells and the relationship between steroidogenesis and glucose metabolism in adult rat Leydig cells.

Advances in Anti-hCGβ Tumor Vaccines;

Expression of HCG and its α,β subunits in esophageal squamous cell carcinoma tissue;

This paper deals with the response curve of HCG enzyme immunoelectrode and analyzes the effect of electrolytic solution pH values on the response.

A novel plug-insert model of piezoelectric tumor markers micro-array immunosensor has been developed by screw apparatus for quantitative detection of tumor markers such as alpha-fetoprotein(AFP),carcino-embryonic antigen(CEA),prostate specific antigen(PSA),human chorionic gonadotropin(hCG) in serum.
