Treatment of the BeWo line of choriocarcinoma cells with methotrexate in doses that inhibit DNA synthesis causes a tenfold increase in synthesis of human chorionic gonadotropin and a threefold increase in activity of placental alkaline phosphatase. No concomitant increase in lactic dehydrogenase activity occurs under these conditions. This effect of methotrexate can be blocked by simultaneous a...

The paper titled “The Effects of Fetal Gender on Serum Human Chorionic Gonadotropin and Testosterone in Normotensive and Preeclamptic Pregnancies” [1], published in Journal of Pregnancy, has been retracted as it is found to contain a substantial amount of material from the paper “Human chorionic gonadotropin and testosterone in normal and preeclamptic pregnancies in relation to fetal sex,” auth...

OBJECTIVE To determine the ability of a sensitive one step urine test to detect human chorionic gonadotrophin in women with suspected complications of early pregnancy. DESIGN Test on women presenting to accident and emergency department with gynaecological problems over six months. Results were validated using a quantitative assay for human chorionic gonadotrophin in serum and urine. SETTIN...

A two year old boy presented with precocious puberty associated with hepatoblastoma. Serum concentrations of beta human chorionic gonadotrophin and alpha-fetoprotein were raised. An aggressive chemotherapeutic regimen resulted in useful palliation and interesting changes in the beta human chorionic gonadotrophin and alpha-fetoprotein concentrations. In contrast to a previous report, the ultrast...

An immunochemical procedure for routine laboratory diagnosis of pregnancy utilizing adsorption of human chorionic gonadotrophin onto kaolin and the Ortho pregnancy test reagents is described. The method is suitable for quantitative assay of urinary human chorionic gonadotrophin and can be adapted for use with serum. It was found to compare favourably with the reliability of Galli-Mainini toad t...

Treatment of immature mice with both follicle-stimulating hormone and human chorionic gonadotrophin in vivo resulted in large increases in the specific activities of ovarian alkaline phosphatase and alkaline nucleotidase. The specific activities of other ovarian enzymes studied were not altered by gonadotrophin treatment. A simultaneous change in the Michaelis constant of ovarian alkaline phosp...
