Effects of chronic stress on nicotine-induced locomotor activity and corticosterone release in adult and adolescent rats
(Blackwell Publishing, 2008-03-01)
We examined nicotine-induced locomotion and increase in corticosterone plasma levels in adolescent and adult animals exposed to chronic restraint stress. Adolescent [postnatal day (P) 28-37] and adult (P60-67) rats were ...
Corticosterone influences gerbil (Meriones unguiculatus) prostatic morphophysiology and alters its proliferation and apoptosis rates
(2017-06-01)
Glucocorticoids (GCs) are hormones that are widely used in medicine; but although side effects are generally recognised, little is known about the precise mechanisms that is implicated in many of these side effects. ...
Role of Corticosterone on Sleep Homeostasis Induced by REM Sleep Deprivation in Rats
(Public Library Science, 2013-05-07)
Sleep is regulated by humoral and homeostatic processes. If on one hand chronic elevation of stress hormones impair sleep, on the other hand, rapid eye movement (REM) sleep deprivation induces elevation of glucocorticoids ...
Physiological stress in captive Greater rheas (Rhea americana): Highly sensitive plasma corticosterone response to an ACTH challenge
(Academic Press Inc Elsevier Science, 2009-12)
Up to the present no studies have been conducted either on baseline concentrations of adrenal hormones or on hormonal responses to stress in Greater rhea (Rhea americana) and most ratite species. The aims of this work were ...
Chronic restraint or variable stresses differently affect the behavior, corticosterone secretion and body weight in rats
(Elsevier B.V., 2007-01-30)
Organisms are constantly subjected to stressful stimuli that affect numerous physiological processes and activate the hypothalamo-pituitary-adrenal (HPA) axis, increasing the release of glucocorticoids. Exposure to chronic ...
Different regulation of cortisol and corticosterone in the subterranean rodent Ctenomys talarum: Responses to dexamethasone, angiotensin II, potassium, and diet
(Academic Press Inc Elsevier Science, 2019-03)
When harmful environmental stimuli occur, glucocorticoids (GCs), cortisol and corticosterone are currently used to evaluate stress status in vertebrates, since their secretions are primarily associated to an increased ...
Risk assessment behaviors associated with corticosterone trigger the defense reaction to social isolation in rats: Role of the anterior cingulate cortex
(INFORMA HEALTHCARELONDON, 2013-08-02)
The extent to which the hypothalamic-pituitary-adrenal axis is activated by short-term and long-term consequences of stress is still open to investigation. This study aimed to determine (i) the correlation between plasma ...
Effects of chronic stress on nicotine-induced locomotor activity and corticosterone release in adult and adolescent rats
(Blackwell Publishing, 2008-03-01)
We examined nicotine-induced locomotion and increase in corticosterone plasma levels in adolescent and adult animals exposed to chronic restraint stress. Adolescent [postnatal day (P) 28-37] and adult (P60-67) rats were ...
THE EFFECT of CORTICOSTERONE in RATS SUBMITTED TO the ELEVATED PLUS-MAZE and TO PENTYLENETETRAZOL-INDUCED CONVULSIONS
(Elsevier B.V., 1994-12-01)
1. in order to examine the effects of corticosterone in the anxiety response, the effect of acute, subchronic and chronic corticosterone (CORT) administration were studied using two animal models to study using two animal ...
Plasma corticosterone elevation inhibits the activation of nuclear factor kappa B (NFKB) in the Syrian hamster pineal gland
(INFORMA HEALTHCARELONDON, 2013-08-02)
We evaluated how the mild stress-induced increase in endogenous corticosterone affected the pineal gland in Syrian hamsters (Mesocricetus auratus). The animals were maintained under constant light for 1 day, instead of a ...
