Ectopic secretion of beta-human chorionic gonadotropin is considered a poor prognostic marker in epithelial tumors. However, very few cases have been reported in sarcomas. We present the case of a 26-year-old female who presented with a metastatic osteosarcoma. She underwent usual testing prior to starting treatment and was found to have elevated levels of beta-human chorionic gonadotropin. As ...

A study was conducted aimed at establishing a range of plasma concentrations of the beta subunit of human chorionic gonadotrophin that might predict ectopic pregnancy after in vitro fertilisation and embryo transfer. From May 1984 to February 1986, 161 consecutive pregnancies at the Monash University in vitro fertilisation unit were analysed by determining plasma beta human chorionic gonadotrop...

background: there is evidence of antibacterial properties of human chorioamniotic layer. however, the distinctive contribution of its individual parts, amniotic and chorionic membranes, to these effects is still unknown. the aim of present study was comparison of the antibacterial effects between amniotic and chorionic membranes. methods: chorioamniotic layer was removed from placenta belonging...

background: the value of serial measurement of serum ß subunit of human chorionic gonadotropin (ßhcg) and ultrasonography in the early diagnosis of ectopic pregnancy has well established. objective: the objective of this study was to explore the diagnostic value of raising level of serum ßhcg, single measurement of progesterone (p) and estradiol (e2) in early diagnosis of ectopic pregnancy. mat...

background: abnormal oocyte morphology has been associated with the hormonal environment to which the gametes are exposed. objective: in this study, we evaluated the oocytes morphology, fertilization rate, embryos quality, and implantation rate resulted of retrieved oocytes in different times after human chorionic gonadotrophin (hcg) administration. materials and methods: a total of 985 metapha...

abstract: introduction & objective: the infertility treatment by using in vitro matured oocyte has many potential applications. it minimizes the risk of ovarian hyper stimulation and is an alternative treatment for women with polycystic ovarian syndrome who may have problems regarding stimulation for ivf. this method may prove important for subjects in need of fertility preservation and also pr...

A new commercially available chemiluminescence immunoassay for the quantitative measurement of human chorionic gonadotropin and its beta-subunit in serum was compared with the enzyme immunoassay used in our routine laboratory. Human chorionic gonadotropin was determined in serum from pregnant women, as well as from women with abortus imminens, suspected ectopic pregnancies or with molar pregnan...
