... of MDMA (125 mg), methylphenidate (60 mg), MDMA + methylphenidate, and placebo on 4 separate days using a cross-over study design. Cortisol, cortisone, corticosterone, 11-dehydrocorticosterone, aldosterone, 11-deoxycorticosterone, dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS...

...Miroslava Macova; Ines Armando; Jin Zhou; Gustavo Baiardi; Dmitri Tyurmin; Ignacio M. Larrayoz-Roldan; Juan M. Saavedra We studied the effect of ovariectomy and estrogen replacement on expression of adrenal angiotensin II AT 1 and AT 2 receptors, aldosterone content, catecholamine synthesis...

... but was unaffected by the type I antagonist RU28318. In contrast, the type I agonist aldosterone (ALDO) in the PVN stimulated feeding in both sham and ADX rats by preferentially enhancing fat ingestion, which could be inhibited by the type I antagonist RU28318 but not by the type II antagonist RU486. These results...

...Shuang-Bao Hu; Lesley A. Tannahill; Stafford L. Lightman Dexamethasone and aldosterone inhibit hypothalamic corticotropin releasing factor-41 (CRF) release. The possible receptors through which these adrenal steroids affect CRF release were studied using rat fetal hypothalamic cell cultures...

...Helmut Geiger; Udo Bahner; Miklós Palkovits; Elisabeth Nicklas; Christian Hugo; August Heidland The effect of aldosterone and dexamethasone on the concentrations of atrial natriuretic peptide (ANP) in preoptic and hypothalamic nuclei was examined in adrenalectomized and intact rats. Five days after...

...Ana Maria Magariños; Mónica Ferrini; Alejandro F. De Nicola Stereoselective competition was used to determine ( 3 H)-aldosterone binding to type I corticosteroid receptors, and ( 3 H)-dexamethasone binding to type II receptors in punches obtained from 11 brain regions of short-term adrenalectomized...

...Eduardo Ortí; Ana Maria Magariños; Alejandro F. De Nicola Cytosol from the spinal cord (SC) of adrenalectomized rats was incubated with a range of [ 3 H]-aldosterone (ALDO) concentrations and the results analyzed according to Scatchard. High affinity (Kd < 1 nM) as well as low affinity (Kd 30...

...Bruce S. McEwen; Laren T. Lambdin; Thomas C. Rainbow; Alejandro F. De Nicola In order to establish the in vivo specificity of the mineralocorticoid recognition system of the rat brain, we investigated the potencies of aldosterone (ALDO) and corticosterone (CORT) in suppressing salt intake...

... target tissues, dissociation constants (KD) for binding of [ 125 I]-SARILE were in the nanomolar range and were the same between control and treated rats. Using conscious rats, estradiol treatment for 7 days was also shown to block the release of aldosterone by low dose infusions of AII (10 ng/min, 30...

...Richard Relkin; Masazumi Adachi An experiment was performed to determine the effectof sodium deprivation on pituitary and plasma radioimmunoassayable proiactin, growth hormone and thyrotropin, aldosterone and total corticosteroid secretory rates, plasma corticosterone, pineal, adrenal and body...
