title: Acute effects of metabolic hormones in swine.
abstract: Many metabolic hormones (glucagon, hydrocortisone, corticosterone, TSH, thyroxine and triiodothyronine) did not stimulate porcine adipose tissue lipolysis in vitro. Growth hormone and ACTH stimulated lipolysis at high concentrations, in the presence of theophylline. Insulin inhibited lipolysis. Infusion of metabolic hormones with measurement of plasma free fatty acid and glycerol concentrations, purportedly indicative of in vivo lipolysis, indicated that glucagon and somatotropin had no effect, adrenocorticotropin increased and insulin depressed plasma concentrations of the metabolites. Overall, the in vitro predicts the in vivo response. There were exceptions, e.g. adrenocorticotropin moderately increased plasma metabolites but had little effect in vitro.
