The hypothalamo-hypophyseal neurosecretory system of the parakeet, Melopsittacus undulatus
General and Comparative Endocrinology, 1961Abstract The hypothalamo-hypophyseal neurosecretory system of the parakeet, Melopsittacus undulatus, was studied with both light and electron microscopes. The neurosecretory centers consist of paired supraoptic nuclei and paraventricular nuclei. Each nucleus is divisible into medial and lateral cell groups. The neurosecretory axonal tracts arising in

Neurosecretion in the hibernating bat. The morphology of the hypothalamo‐hypophyseal system
The Anatomical Record, 1965AbstractThe morphology of the hypothalamo‐hypophyseal tract of 35 hibernating bats (Myotis lucifugus lucifugus) was studied in chrome‐alum‐hematoxylin‐phloxine‐stained serial coronal and sagittal sections. Vinyl acetate and wax‐plate reconstructions also aided in describing the two neurosecretory hypothalamic nuclei of this system. The most prominently

The hypothalamo-hypophyseal neurosecretory system of Gegenophis carnosus Beddome
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 19571. The brain of Gegenophis carnosus Beddome resembles that of Ichthyophis glutinosus in general organisation. In size, shape and structure the hypophysis of Gegenophis differs from that of other groups of Amphibians. The pars nervosa is at the posterior tip of the hypophysis and is connected to the brain by a nervous tract. 2.

Effects of Indomethacin on the Hypothalamo-Hypophyseal Neurosecretory System
1978Four groups of animals were investigated: intact rats, waterdeprived rats, rats given indomethacin, and rats initially given indomethacin and then transferred to water-deprived conditions while continuing to receive indomethacin. Some animals were investigated 3 days after being water deprived.

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 ...

[The hypothalamo-hypophyseal system: the role of calcium ions].
Bollettino della Societa italiana di biologia sperimentale, 1983The Authors investigated the effects of Verapamil a calcium antagonist substance upon the pituitary response to several secretogogus agents in ten male healthy subjects in order to elucidate the calcium role in the regulation of the hypothalamic pituitary function.

[The hypothalamo-hypophyseal system in resistant ovary syndrome].
Akusherstvo i ginekologiia, 1990The study has been done in 30 women with the resistant ovary syndrome diagnosed by laparoscopy, laparotomy and histologic examination of ovarian biopsy samples. Genetic study identified the feminine phenotype and genotype (46,XX). Estradiol levels corresponded to those seen in the follicular menstrual phase, prolactin levels were normal, and ...

[The effect of adenosine on the hypothalamo-hypophyseal-adrenal system].
Fiziolohichnyi zhurnal (Kiev, Ukraine : 1994), 1996The effect of various doses of intraperitoneally administered adenosine on the content of corticotropin and corticosteroids on the blood plasma was studied in Wistar rats. Dependence of the effect exerted by adenosine on the hypothalamo-pituitary-adrenal system on its dose was demonstrated: 1 hour after nucleoside administration in a dose of 50 mg/kg ...
