An accumulation of monoamines is found in the adult eminentia mediana and infundibular stem, close to the capillaries of the primary plexus, where they seem to be stored mainly in closely packed delicate varicose fibres, often with swollen endings, “droplets”.

Rats with inherited stress-induced arterial hypertension (NISAG rats) and normotensive Wistar rats were used for studies of age-related changes in arterial pressure (BP), in the activity of the hypothalamo-hypophyseal-adrenocortical system (HHAS), and noradrenaline levels in brain structures involved in regulating these functions, with the aim of ...

State of the hypothalamo-hypophyseal neurosecretory system of rabbits after anaphylactic shock
Bulletin of Experimental Biology and Medicine, 1976The hypothalamo-hypophysial neurosecretory system of rabbits was investigated 1, 3, 7, 14, and 21 days after the anaphylactic shock. It was found morphometrically that dimensions of the nucleoli of the supraoptic and paraventricular nuclei gradually increased as compared with the moment of anaphylactic shock, but did not reach the control level ...

Effects of Sucrose on the Hypothalamo-hypophyseal System of Toad Tadpoles
1958It is known that the treatment of amphibian embryos with 10 % sucrose solution produces albinism. Eakin(1953) and Driscoll and Eakin(1955) have demonstrated that the latter phenomenon depends upon the fact that the intermediate lobe fails to differentiate.

The hypothalamo-hypophyseal neurosecretory system of the ring-necked snake, Diadophis punctatus
General and Comparative Endocrinology, 1965The hypothalamo-hypophyseal neurosecretory system was studied in the ring-necked snake Diadophis punetatus. The appearance of neurosecretory material in the hypothalamus, median eminence and pars nervosa is described on the basis of sections stained with Gomori's aldehyde fuchsin. Intraperitoneal injections of sodium chloride caused marked depletion

Age-related vasopressin changes in rat plasma and the hypothalamo-hypophyseal system
Experimental Gerontology, 1982Immunoreactive vasopressin (VP) weas measured in the plasma, neurohypophysis (NH) and hypothalamus (HT) of young (3 months), adult (12 months), and old (30 months) Sprague-Dawley male rats, both intact and anesthetized with halothane. VP content in the HT of the old rats was about half that of young and adult rats.

Hypothalamo-Hypophyseal System in Calamoichthys calabaricus smithi (Polypteriformes)
1978Polypteriformes are a singularly primitive group of African freshwater bony fishes, regarded as paleoniscid relicts, which are the extinct ancestors of the entire actinopterygian stock (MOY-THOMAS, 1939; ROMER, 1946). The hypothalamo-hypophyseal complex of Polypteriformes was studied from a general point of view by DODD and KERR (1963) and WINGSTRAND ...

Brain‐Derived Neurotrophic Factor in the Hypothalamo‐Hypophyseal System of Xenopus laevis
Annals of the New York Academy of Sciences, 2005Abstract: Brain‐derived neurotrophic factor (BDNF) is immunocytochemically demonstrated in the magnocellular nucleus and neural lobe of the pituitary gland of the amphibian Xenopus laevis. Immunoelectron microscopy shows BDNF in secretory granules of type A neurohemal axon terminals in the neural lobe of pituitary gland.

Functions of the hypothalamo-hypophyseal-adrenal system in aging in female monkeys.
Neuroscience and behavioral physiology, 2000Comparative studies on the functioning of the adrenal cortex in female rhesus macaques (Macaca mulatta) of different ages are reported - animals were aged 6-9 years (young adults; n = 5) and 20-26 years (old adults; n = 5). Corticosteroid concentrations (cortisol (F) and dehydroepiandrosterone sulfate (DHEAS)) were determined by specific ...

Journal of Comparative Neurology, 1971
AbstractThe hypothalamo‐neurohypophyseal system of the catfish, as revealed by in situ techniques, consists of the prominent nucleus preopticus, the axonal tracts, and the neurohypophysis. The preoptic nucleus, which is composed of the pars magnocellularis and the parvocellularis, is situated on either side of the optic recess slightly anterior to the ...
