title: Hematologic, biochemical, and endocrine effects of dexamethasone on bottlenose dolphins (Tursiops truncatus).
abstract: Two Atlantic bottlenose dolphins (Tursiops truncatus) were given 0.11 mg/kg dexamethasone p.o., and complete blood count and serum chemistry analyses, including insulin, thyroxine (T4) adrenocorticotrophic hormone (ACTH), and cortisol level determinations, were performed at 0 hr, 24 hr, 36 hr, 48 hr, 7 days, and 17 days. Significant changes included neutrophilia, eosinopenia, lymphopenia, elevated insulin, and depressed ACTH and cortisol levels within 24 hr of dexamethasone administration. These effects were rapid, and values returned to normal within 48 hr.
