... embryos were progressively collected to study the extent (if any) of the adenohypophyseal tissue. The results revealed that Rathke’s pouch and later the adenohypophysis were completely absent in 33 out of the 45 studied embryos. The surrounding tissues in the operated embryos developped in a comparable...

... nucleus, the nucleus raphe magnus, the nucleus raphe obscurus and the locus coeruleus. In these areas a weak to moderate nuclear GR IR developed in nerve cells 1 or 2 days after the appearance of the GR mRNA signal. From El 5 the adenohypophysis showed the strongest expression of GR mRNA. At E17 a strong...

... with production of both hormones by mammosomatotrophs. The onset of hormone release by cultured human fetal pituitaries correlates with the detection of hormones biochemically and immunohistochemically. Responsiveness of fetal adenohypophysial cells to hormonal influences indicates functional maturity early...

... the development of cell differentiation and hormone production in the adenohypophysis. At 5 weeks of gestation, Rathke’s cleft was lined by columnar epithelium with abundant cytoplasmic glycogen and occasional secretory granules. By 6 weeks of gestation, cells resembling corticotrophs were identified; in 8-week...

... peptidase. The effect of thyroid hormone status on the activity of these enzymes was evaluated in serum and various tissues. Only in adenohypophysis, triiodothyronine treatment increased PGAII to 376% of control; hypothyroidism produced the reverse effect (decrease to 23% of control). As previously reported...

... for such radioligand binding demonstrated that ligand specificity of adenohypophysial receptors was distinctly different from that of cerebral cortex. Two cyclic octapeptides D-Phe-Cys-Tyr-D-Trp-Lys-Val-Cys-Thr-NH 2 and D-Nal-Cys-Tyr-D-Trp-Lys-Val-Cys-Thr-NH 2 bound to pituitary SRIF receptors with high affinity [Ki...

..., TRH was quantified in the median eminence and in the mediobasal hypothalamus; in the adenohypophysis the membrane receptors for TRH were evaluated as well as the accumulation of TRH in the gland. As for TSH, its concentration was determined in the anterior pituitary gland and in plasma...

...Sylvia L. Asa; Kalman Kovacs; Ferenc A. Laszlo; Istvan Domokos; Calvin Ezrin One hundred and forty human fetal pituitary glands were removed from fetuses at 7–40 weeks of gestation and studied by light microscopy and immunocytochemistry to localize adenohypophysial hormones. For immunocytology...

... adenohypophysis. After fractionation of tissue homogenates in 0.25 M sucrose by differential centrifugation, about 25% of the total cellular GnRH degrading activity was found to be sedimentable and recovered from heavy (M) and light (L) mitochondrial fractions with a distribution pattern similar...

...Linda Lenhard; Leonard J. Deftos The presence of adenohypophyseal hormones in human cerebrospinal fluid (CSF) has been firmly established by radioimmunoassay procedures. The hormones can originate from the adenohypophysis itself and from brain, as well as from peripheral sites of production...

... in the adenohypophysis of rats with diabetes insipidus. A partial purification of the VP-like peptide showed that it had the chromatographic and electrophoretic properties of VP. It could be identified with arginine vasopressin (AVP) in the case of the rat and lysine-vasopressin (LVP) in the case of the pig...

...Sofia Avissar; Yaacov Egozi; Mordechai Sokolovsky The ligand binding properties of muscarinic receptors present in rat adenohypophysis were studied using the tritiated antagonists N-methyl-4-piperidyl benzilate, 3-quinuclidinyl benzilate, and methylscopolamine. Equilibrium analysis of antagonists...

...I. Pollard; J.R. Bassett; K.D. Cairncross A morphological and ultrastructural study is described which indicates that cellular activity in the adenohypophysis correlates well with the circulating levels of corticosterone. Intense secretory activity is observed in all tropic cells...

...B.K. McLean; M.B. Nikitovitch-Winer The direct effects of median eminence extract (MEE), estradiol (E) or progesterone (P) or combinations of these hormone preparations on the structure of the adenohypophysis and its secretion of gonadotrophins were examined in female rats bearing pituitary...

...Irene von Lawzewitsch; Luciano Debeljuk; Raúl Puig Administration of crude and semipurified beef hypothalamic extracts to normal male rats resulted in a considerable degranulation of acidophil, thyrotropic and gonadotropic cells of the adenohypophysis. This effect was evidenced from 10 to 20 min...
