In on-going studies of 'classical' and ring B-unsaturated oestrogens in equine pregnancy, the products of metabolism of [2,2,4,6,6-2H(5)]-testosterone and [16,16,17-2H(3)]-5,7-androstadiene-3 beta,17 beta-diol with equine placental subcellular preparations and allantochorionic villi have been identified. Using mixtures of unlabelled and [2H]-labelled steroid

In the present study, the constant infusion of [3H]17 beta-dihydroequilin sulfate ([3H]17 beta-EqS) was used to estimate the metabolic clearance rate (MCR) of 17 beta-dihydroequilin sulfate (17 beta-EqS) and to measure the conversion of this estrogen to equilin sulfate (EqS)

Premarin, which contains several equine estrogens, as well as estradiol (E2) as a minor component, is widely used for replacement therapy of estrogen deficits, but little is known of its direct actions on brain cells. In mixed glial cultures, apolipoprotein

The MCRs of 17 beta-dihydroequilin sulfate and 17 beta-dihydroequilin were determined in normal postmenopausal women by single iv injection of either 17 beta-[3H]dihydroequilin sulfate ([3H]17 beta-EqS) or 17 beta-[3H]dihydroequilin ([3H]17 beta-Eq). After the administration of [3H]17 beta-EqS, blood was drawn

The present investigation was undertaken to compare the binding affinities (Ka) of the ring B unsaturated equine estrogens (equilin [Eq], equilenin [Eqn], 17 beta-dihydroequilin [17 beta-Eq], 17 beta-dihydroequilenin [17 beta-Eqn], 17 alpha-dihydroequilin [17 alpha-Eq], and17 alpha-dihydroequilenin [17 alpha-Eqn]) and the
