Stress-induced secretion of adrenocorticotropin in rats is inhibited by administration of antisera to ovine corticotropin-releasing factor and vasopressin.

abstract：:The original objective of this study was to use available distribution volume (V) and deca constant (k) estimates for rat LH and FSH to determine the amounts of these hormones synthesized and released during a dynamic secretory event, the postpartum preovulatory surge. The problem was approached by 1) determining the ...
