... the current availability of oestrogen and progesterone preparations worldwide. Methods: Endorsed by the ESPE Turner Syndrome Working Group, the questionnaire targeted paediatric endocrinologists. Questions focused on accessibility of oral/transdermal 17β-estradiol and progestogen preparations. Responses were...

... a biological effect on the steroid receptor with clinical consequences on diagnostics and treatment in CAH patients. Therefore, we analysed the effect of accumulated steroids [17-hydroxyprogesterone (17OHP), progesterone, androstenedione and testosterone] on aldosterone-mediated transactivation of the human...

...H. Ahmed-Sorour; C.J. Bailey This study examines the effects of ovarian hormones on the glycaemic actions of insulin, glucagon and epinephrine. Ovariectomized adult female mice were treated with replacement doses of oestradiol, progesterone, both hormones combined or vehicle only for 15 weeks...

... posttranslational effects, and lipolysis is markedly stimulated. Testosterone inhibits LPL expression and, in the presence of GH, markedly increases lipolysis via multiple interactions along the lipolytic cascade. In human adipose tissue, direct effects of estrogen and progesterone cannot be demonstrated, probably...

..., adrenergic drugs and β-blocker for 1 h. DA, norepinephrine (NE) and isoproterenol (Iso) increased the level of progesterone (P 4 ) and cAMP in the conditioned medium. D 1 agonists (SKF38393, SKF82526J, CY208-243) increased P 4 secretion, while the D 2 agonist, bromocriptine, showed no significant effect on P...

... rhythm was seen in cortisol, with a lower-amplitude rhythm in progesterone (AM/PM = 1.12). Evening samples showed a rise in cortisol, with a highly significant rise on day -1. The rise was small. The fall in progesterone in the 3 days before parturition was also small (approximately 6%). Neither change...

...K. Kusuhara In order to clarify the relationship between endometrial histology and progesterone (P 4 ), plasma P 4 and estradiol levels in the luteal phase were measured in 126 cases of unexplained infertility. Endometrial biopsies were performed in the midluteal period of menstrual cycles. Forty...

...K. Tanabe; T. Tamura; A. Saijo; M. Kikuchi; R. Sho; A. Mashu; T. Kobayashi; S. Nozawa The influence of testosterone, androstenedione and dihydrotestosterone (DHT) on the progesterone (P 4 ) production by cultured porcine granulosa cells was studied in the presence or absence of gonadotropins...

...David R. Garris The effects of diabetes on the uptake and incorporation of 3 H-progesterone (P) in various brain areas and peripheral tissues were analyzed in C57BL/KsJ mice. Littermate control (+/?) and diabetic (db/db) mice were pulse-treated (60) min with 10 µCi of 3 H-P at either 8 or 16 weeks...

... nmol/l, iliac 164.46 ± 31.02 nmol/l, n = 17, p < 0.01). This indicates that spermatic blood collected at the scrotal sampling point has received more blood coming from the testis than the blood collected at the iliac point. We did not observe significant differences in progesterone and Δ4-androstene...

...P. Mauvais-Jarvis; F. Kuttenn; A. Gompel This review analyzes recent data from international literature concerning the antiestrogen action of progesterone and progestins at the level of mammary cells in culture from either breast cancer lines or normal breast obtained from reduction mammoplasties...

...) and a significant stimulation of progesterone receptor protein (10–16 times higher than in control animals). At the same time, there was a 50–70% decrease in the total estrogen receptor concentration. 10 03 1982 6 10 1982 26 11 2008 © 1983 S. Karger AG, Basel 1983 Copyright / Drug Dosage...

...W. Sorgo; B. Manella; M. Zachmann A rapid specific radioimmunoassay for progesterone in mixed, unstimulated saliva is described. Column chromatography is not necessary. One single extraction with petroleum ether provides a fractional recovery of 75–95%. The assay sensitivity is 9 pg progesterone...

... corticosterone level of PXH rats was significantly depressed while heat or pinealectomy alone had no effect. Mean oestrous cycle length was prolonged and blood serum progesterone was increased in the heat-exposed rats. However, the extended oestrous cycles and elevated serum progesterone levels of heat-exposed...

..., prolactin, progesterone and TPA stimulated the rate of (3H)-thymidine incorporation into DNA. A significantly lower response towards prolactin and TPA was observed in mammary explants derived from GR/Mtv-2 - mice. The differential sensitivity of mammary tissues from GR and GR/Mtv-2 - mouse strains...

...S.M. Walker; R.F. Walker; D. Riad-Fahmy A ‘normal range’ for salivary progesterone concentrations has been established using data derived from women who were menstruating regularly and in whom dating of the cycle by accepted criteria was possible. Since these values are in agreement with those...

...Yaroslav Kolena; Cornelia P. Channing Follicular fluid obtained from large (6-12 mm) porcine follicles (LFF) was investigated to determine its stimulatory activity on progesterone secretion and on follicle stimulating hormone (FSH) induction of 125 I-human chorionic gonadotropin (hCG)-luteinizing...

...L.J. Carrington; C.J. Bailey Glycogen deposition and glucose tolerance were examined in female mice after 24 days of oral treatment with natural (17β-estradiol and progesterone) and synthetic (ethinyl estradiol and norethisterone acetate) sex steroids, administered individually and in estrogen...

... to prolactin, followed by corticosterone, androstenedione, and progesterone. We conclude that prolactin is an adrenocortical secretagogue of physiological relevance in the rat, and that it could play a role in enhancing the action of ACTH to acutely release steroids. 25 11 1983 3 05 1984 26 11...

...I. Nir; N. Hirschmann Serum and pituitary LH, prolactin and progesterone changes recorded in parturient rats exposed to continuous darkness throughout pregnancy were not prevented by early ablation of the pineal gland. Similarly, the shorter gestation period observed in rats kept in continuous...
