Developmental programing of thirst and sodium appetite.
Thirst and sodium appetite are the sensations responsible for the motivated behaviors of water and salt intake, respectively, and both are essential responses for the maintenance of hydromineral homeostasis in animals. These sensations and their related behaviors develop very early in the postnatal period in animals. Many studies have demonstrated several pre- and postnatal stimuli that are res...
متن کاملAngiotensin, thirst, and sodium appetite.
Angiotensin (ANG) II is a powerful and phylogenetically widespread stimulus to thirst and sodium appetite. When it is injected directly into sensitive areas of the brain, it causes an immediate increase in water intake followed by a slower increase in NaCl intake. Drinking is vigorous, highly motivated, and rapidly completed. The amounts of water taken within 15 min or so of injection can excee...
متن کاملOdd Cravings, Appetite, Hunger, and Thirst
Cravings for food as appetite and hunger is a healthy reflex reaction to the body’s need for nutriment, just as thirst is the subjective physiological reaction to dehydration. Hypothalamic neuro-peptides released in response to nutritional demands affect brain circuits driving hunger. Unusual cravings for non-nutritive foods or uncontrollable desires for odd choices or combinations of food may ...
متن کاملEvidence that brain angiotensin II is involved in both thirst and sodium appetite in baboons.
The roles of ANG II in the brain mechanisms subserving thirst and Na appetite in baboons were investigated by chronic intracerebroventricular infusions of ANG II and AT1-receptor antagonists using subcutaneous miniosmotic pumps and by oral administration of captopril. ANG II at 3 or 5 micrograms/h for 7 days increased water intake from 2,455 +/- 107 to 7,052 +/- 562 ml/day by day 6 and 300 mM N...
متن کاملAssessment of brain AT1-receptor on the nocturnal basal and angiotensin-induced thirst and sodium appetite in ovariectomised rats.
OBJECTIVE Considering the controversial data regarding the role of the brain renin-angiotensin system (RAS) on the thirst and sodium appetite in ovariectomised rats, we aimed to evaluate the role of the brain angiotensin II (Ang II) AT1-receptor on the nocturnal fluids intake. MATERIALS AND METHODS Groups of Wistar female rats were ovariectomised and chronically given oestrogen or vehicle to ...
