...P. Kosterin; A.L. Obaid; B.M. Salzberg Background/Aims: Complex intrinsic optical changes (light scattering) are readily observed in the neurointermediate lobe of the mouse pituitary gland following electrical stimulation of the infundibular stalk. Our laboratory has previously identified three...

...), Wistar (W), Wistar-Kyoto (WKY) and spontaneously hypertensive rats (SHR). Release of vasopressin was studied in vitro by placing neurointermediate lobes in perfusion chambers. It was stimulated twice by 50 m M KC1 (S1 and S2) and the ratio between the first and the second stimulation was calculated (S2...

Cardinali After bilateral superior cervical ganglionectomy (SCGx) in adult male rats, norepinephrine content of the pituitary neurointermediate lobe () decreased at 12–24 h after surgery to attain concentrations 40...

... of the D-2 DA receptor. To test whether either dopaminergic effect occurs at the level of neurosecretory endings in the neurointermediate lobe (), the stalk- was isolated from lactating rats and perifused in vitro. The stalk- junction was electrically stimulated for 4 s, and the effects of selective D-1 DA...

...Katherine D. Fagin; Sandra G. Wiener; Mary F. Dallman Surgical removal of the neurointermediate lobe of the pituitary gland (-X) in the rat resulted in two abnormalities in ACTH secretion: (1) plasma ACTH and corticosterone levels were elevated in the morning and over a 24-hour period compared...

...B. Briaud; B. Koch; B. Luiz-Bucher; C. Mialhe The effect of various neurotransmitters on adrenocorticotropic hormone (ACTH) release from superfused neurointermediate lobes of rat hypophysis (NIL) was investigated. Acetylcholine, serotonin, and histamine were shown to have no significant effect...

Mialhe Alterations in the ionic composition of the medium and different secretagogues have been used in order to study the mechanism of release of ACTH from superfused neurointermediate lobes (NIL) of rat hypophysis. We showed that: (a) a tenfold increase of K...
