title: Lack of rapid effects of cortisol on parathyroid hormone levels in cattle.
abstract: Experiments were performed to study plasma concentrations of parathyroid hormone in association with short-term changes of cortisol and dexamethasone. Parathyroid hormone was not significantly modified during 3-hour intravenous infusions of cortisol, leading to marked elevations (p less than 0.001) of plasma cortisol levels, and during intravenous administration of dexamethasone. Thus glucocorticoids, at least in cattle, apparently cause no short-term changes of plasma parathyroid hormone levels.
