There was no significant difference in the increase of plasma cortisol following intravenous or intramuscular injection of ACTH (beta1-23). Peak values were reached at 60 min (65.2 +/- 3.2 mug/100 ml). This is considered...年份: 1974 ...
After stimulation, this difference disappeared, but rarely were any hamster's cortisol levels higher than their corticosterone levels. Both ACTH and acute stress elevated plasma corticosterone and cortisol concentrations, but only plasma cortisol concentrations were elevated following chronic stress. The ...
Within potential target cells, the actions of physiological glucocorticoids (cortisol and corticosterone) are modulated by isoforms of the enzyme 11 beta-h... A Michael,L Thurston,M Rae - 《Reproduction》 被引量: 264发表: 2003年 Seasonal steroid hormone levels and their relation to reproduction ...
Glucocorticoids (corticosterone in birds and rodents and cortisol in all other mammals) are glucoregulatory hormones that are synthesized in response to a ... CR Ralph,AJ Tilbrook - 《Journal of Animal Science》 被引量: 9发表: 2016年 INVITED REVIEW: The usefulness of measuring glucocorticoids for...
18 Corticosterone in plasma shows a similar picture: it is higher and persists longer in animals stressed but once.18 Recently we have provided further evidence explaining this difference: in a similar experiment on animals immobilized 40 times, ACTH levels were found to be significantly lower...
In response to stress, the release of adrenocorticotropic hormone (ACTH) subsequently activates the secretion of corticotropin-releasing factor (CRF), which induces glucocorticoid synthesis and their systemic release (cortisol in humans and corticosterone [CORT] in rodents)4. When glucocorticoid binds to...
There was no difference in the structure of go trials once the stop signal trials were introduced. Rats generally required several days of training to learn to withhold responding on stop trials. Once rats learned to respond with at least 65% accuracy on both stop and go trials, they were ...
Research Note: Sex difference in changes in heterophil to lymphocyte ratios in response to acute exposure of both corticosterone and cortisol in the Pekin duck Poultry Science 101:101914. I made the following observations regarding the application of the H/L ratio, a subject in which I have ...
MRs bind corticosterone and aldosterone with a very high affinity (Kd ∼ 0.5 nM), while the affinity for cortisol is about 10-fold lower. Since corticosterone circulates in a 100-fold excess over aldosterone, this implies that MRs are, to a large extent, occupied by corticosterone. The hyp...
