Besides stimulating GH release, some GH secretagogues also release ACTH and adrenal steroids. Several novel classes of potent GH secretagogues have recently been described, and we have now tested their ability to release corticosterone in conscious normal rats. All analogs that released GH also stimulated corticosterone release to some degree, though the(More)
We have studied the effects of desmethylimipramine (DMI), a tricyclic antidepressant, on thyroid hormone (TH) handling in rat brain in an effort to discover a pharmacological basis for reported interactions between TH, affective disorders and psychotropic drugs. An acute dose of DMI has been used in order to determine the primary effects of the drug in(More)
The tricyclic antidepressant, desmethylimipramine (DMI), a highly selective inhibitor of presynaptic uptake of norepinephrine (NE), has also been shown to reduce [125I]3,3',5-triiodothyronine (T3) uptake in rat brain synaptosomes. Using DMI as a probe to examine 1) possible noradrenergic influences on thyroid hormone (TH) actions in brain and 2)(More)
Several lines of evidence point to an interaction between amine uptake inhibitors (tricyclic antidepressants) and thyroid hormones. To examine this issue under conditions which would minimize secondary effects of drug treatment, desmethylimipramine (DMI), a highly specific norepinephrine uptake inhibitor, was given acutely as a single i.p. dose one hour(More)
