W J Brock et al.
The Journal of pharmacology and experimental therapeutics, 229(1), 175-181 (1984-04-01)
The uptake of estradiol-17 beta(beta-D-glucuronide) (E(2)17G), estriol-16 alpha(beta-D-glucuronide (E(3)16G), estradiol-17 beta-3-(beta-D-glucuronide) (E(2)3G) and taurocholate (TC) into hepatocytes isolated from male and female rats was examined and found to be linear for at least 75 sec and to exhibit Michaelis-Menten kinetics.
K Musch et al.
Zeitschrift fur Geburtshilfe und Perinatologie, 185(5), 284-287 (1981-10-01)
A method based on the inhibition of hemagglutination for the determination of estriol-16-alpha-glucuronide is compared to the method of Kober and Ittrich. A sufficient degree of correlation (p less than 0.001) is found, when the daily estrogen production (Kober-Ittrich) in
M Höller et al.
Acta endocrinologica, 100(1), 57-62 (1982-05-01)
Equimolar concentrations of [4-14C]oestriol and [6,9-3H]oestriol 16 alpha-monoglucuronide were simultaneously perfused through isolated rat livers. Oestriol was hydroxylated to 2-hydroxyoestriol and 6 xi-hydroxyoestriol; 2-hydroxyoestriol was further methylated to 2-methoxyoestriol. Oxidoreduction of oestriol led to the formation of 16 alpha-hydroxyoestrone, 16-0xooestradio-17
F Andreolini et al.
Clinical chemistry, 31(1), 124-126 (1985-01-01)
In this relatively simple, rapid assay of estriol-16 alpha-glucuronide in pregnancy urine, the urine sample is diluted 20-fold with phosphate buffer (pH 5.2) containing 360 mL of acetonitrile and 2 g of cetyltrimethylammonium bromide per liter, then directly injected into
K L Cheesman et al.
Fertility and sterility, 38(5), 542-548 (1982-11-01)
The concentration of luteinizing hormone (LH), pregnanediol-3-glucuronide (PGD), and estriol-16-Glucuronide (E3G) were measured in daily morning urine specimens from 53 infertile women. In 26 of 29 women with various degrees of proven endometriosis, two distinct midcycle peaks of LH were
