...Anders Bergenfelz; Bo Ahrén It has been suggested that calcium changes the set point of the pituitary thyroid feedback. It is not known, however, if small and slow changes of calcium and/or parathyroid hormone (PTH) within the physiological range influence the serum levels of thyrotropin (TSH...

DeCherney We are interested in the mechanisms by which endocrine and developmental factors regulate TSH synthesis at both pre-translational and post-translational levels. Thyroid...

...Carmelo Scarpignato; Antonella Pezzetta; Edoardo Tarditi The effect of caerulein (100 ng/kg/h × 1 h) on basal as well as on thyrotropin-releasing hormone (TRH)-stimulated prolactin and thyroid-stimulating hormone (TSH) secretion was studied in healthy male volunteers. The peptide did not change...

...P. Carayon; E. Martino; L. Bartalena; L. Grasso; C. Mammoli; S. Costagliola; A. Pinchera Five different ultrasensitive thyrotropin (TSH) assay kits (Boots-Celltech, Immunotech, ORIS-CIS, Travenol and Boehringer) have been used for TSH measurements in various conditions. All the kits were based...

...V. Coiro; U. Butturini; A. Gnudi; R. Volpi; L. d’Amato; G. Speroni; L. Capretti; E. Roti; P. Chiodera The effect of domperidone, a specific blocker of dopamine receptors, on serum TSH and PRL levels was evaluated in 16 euthyroid men affected by insulin-dependent diabetes mellitus (IDDM...

...Alan N. Elias; Nosratola D. Vaziri; M.R. Pandian; Krish Iyer; Mohammad A. Ansari The role of dopamine in the dysregulation of TSH secretion in uremic male rats was investigated using the dopamine antagonist, pimozide. In order to obviate the effect of weight loss due to uremia-induced anorexia...

...Pavel Langer; Daniela Ježová; Ondrej Földes; Klaudia Gschwendtová Cold-induced increase of thyrotropin (TSH) release was found to be inhibited after 10 or 20 mg/kg morphine sulfate (MO) injected intraperitoneally 30 min before the transfer of adult male rats from 30 to 4°C for 60 min (i.e. 90 min...

...Daniel Jordan; Marc Veisseire; Françoise Borson-Chazot; René Mornex We previously observed that under a 12-hour light/12-hour dark schedule (lights off at 19.00 h), adult male Sprague-Dawley rats showed a circadian rhythm for serum thyroid-stimulating hormone (TSH) with a zenith near midday...

...P. Rauhala; R.K. Tuominen; P.T. Männistö In the present study both MR 2034 (ĸ-agonist) and DAMME (µ-agonist) decreased thyrotropin (TSH) secretion stimulated by cold in the rat when infused into the 3rd ventricle. After infusion into the posterior hypothalamus (PH), a small dose of MR 2034...

...E.C. Degli Uberti; G. Trasforini; A.R. Margutti; C.A. Rotola; R. Pansini The possible role of gastrin on TSH, ACTH and cortisol secretion was evaluated by intravenous administration of pentagastrin, the carboxyl-terminal tetrapeptide of gastrin (0.5 µg/kg b.w.) into 12 healthy subjects...

...Alan N. Elias; Agnes V. Szekeres; Sergio Stone; Paul Weathersbee; Lubomir J. Valenta; Tarek Haw The effects of the GABA analogue, baclofen, and the dopamine antagonist, metoclopramide, on basal and TRH-stimulated TSH release were studied in 6 normal male volunteers. Basal TSH secretion...

... of the pituitary-thyroid axis was found which was manifested by an increase of thyrotropin (TSH) and thyroxine (T 4 ) levels at 2–5 min of UR. This was presumably due to the emotional effect of a rapid transfer and to the placing of the animals into restriction cages. Later, between 3 and 6 h of UR, another...

...E. Gemsenjäger; J.J. Staub; J. Girard Eleven patients with single toxic nodular goiter (group A) had no TSH response to TRH (ΔTSH ≤ 1 µU/ml). Nine days after nodulectomy, TSH response was still absent in 10 patients. Responsiveness was delayed for between 2 and 7 weeks and was preceded by increases...

...J. Mattila; P.T. Männistö The role of 5-hydroxytryptamine (5-HT) in the regulation of TSH secretion was studied in male rats using both peripheral and central administration of the drugs. Basal TSH levels were not modified by moderate doses of 5-HT (subcutaneously) or its precursors or antagonists...

...Jyrki Mattila; Pekka T. Männistö The role of the pineal gland in the regulation of thyroid-stimulating hormone (TSH) secretion was studied in postpuberal male rats using 12:12 h light:dark cycles. Pinealectomy, performed 3–4 days before decapitation, had no effect on the basal or thyrotropin...
