The aim of this study was to evaluate the reproductive efficiency of short and long term treatment with progestagens in addition to pregnant mare serum gonadotropin (PMSG) in Arabian ewes during the non-breeding season. A total of 56 ewes were divided into three groups: in group I vaginal sponges (60 mg medroxy progesterone acetate; MAP) were applied and removed after 6 days; in group II, vagin...

Clinical observations and basic studies show that progesterone and progestins have a variable influence on endothelial function. Dydrogesterone (DG) is a widely used progestin, but its endothelial actions have not been thoroughly assessed. In this study, we investigated the effects of DG and its metabolite 20-α-dihydro-dydrogesterone (DHD), natural progesterone as well as medroxyprogesterone ac...
There is considerable evidence from animal studies that gonadal steroid hormones modulate neuronal activity and affect behavior. To study this in humans directly, we used H215O positron-emission tomography to measure regional cerebral blood flow (rCBF) in young women during three pharmacologically controlled hormonal conditions spanning 4-5 months: ovarian suppression induced by the gonadotropi...
The effects of continuous intravenous administration of luteinizing hormone-release hormone in conjunction with physiological or pharmacolog ical doses of estradiol (E2), progesterone (P), 17alphaOH-progesterone (17-P), 20alphaOH-progesterone (20-P), chlormadinone acetate (CA), testosterone (T) and 5alpha-dihydrotestosterone (5-DHT) on pituitary response was evaluated in normal and postmenopau...
Experiments were conducted to examine the in vitro effects of a phorbol ester and a calcium ionophore on bovine luteal oxytocin (OT) secretion and synthesis and progesterone secretion. Corpora lutea removed from beef heifers on d 8 of an estrous cycle were sliced and incubated for 2 h with .81 nM 12-O-tetradecanoylphorbol-13-acetate (TPA), 1.62 nM TPA or .3 microM calcium ionophore A23187. Both...
Pregnant cows were fed pine needles (PN, 2 kg.cow-1.d-1) mixed with the diet to determine factors that affect abortion response. In Exp. 1, treatments were used to determine the effects of experimental stress and pelleting of pine needles. Pelleting needles and experimental stress delayed abortion response (P < .01). Stress-induced delay was associated with abnormal patterns of progesterone and...
UNLABELLED BACKGROUND The resistance of endometriotic tissue to progesterone can be explained by alterations in the distribution of progesterone receptor (PR) and estrogen receptor (ER) isoforms. The aims of this study were to examine the expressions of PR-A, PR-B, ERα and ERβ in endometrioma and assess whether these expressions are affected by dienogest or leuprolide acetate (LA) treatment....
The mammary carcinoma cell line MFM-223 is characterized by high androgen and low estrogen and progesterone receptor levels. With the dextran charcoal method, androgen binding was determined at 160 fmol/mg protein corresponding to approximately 100,000 binding sites per cell in whole cell binding assays. The estrogen and progesterone receptor contents were between 8 and 18 fmol/mg protein. The ...
