In all cases, cortisol level increased three-fold after adrenocorticotrophic hormone.

Plasma adrenocorticotrophic hormone (ACTH) and cortisol levels were determined at serial time points.

These sb mice also had significantly greater increases in plasma adrenocorticotrophic hormone than mice with other genotypes after a stressful stimulus.

Low cortisol levels are almost universal in infants after treatment with dexamethasone, but the adrenal gland remains responsive to adrenocorticotrophic hormone stimulation.

This study was designed to investigate the effect of chronic exercise on exercise-induced changes in plasma concentrations of adrenocorticotrophic hormone (ACTH) and corticosterone in rats.
