* Understand endocrine tests of hypothalamic-pituitary function (cosyntropin test/rapid ACTH stimulation test, insulin hypoglycemia test, metyrapone test, levodopa test, arginine infusion test, glucose-GH suppression test, TRH test, gonadotropin-releasing hormone (GnRH) test, clomiphene test, corticotro...
(Kanekoet al., 1977). The early 5-min peak is due to the stimulation of release of stored insulin by the beta cells by glucose. In humans, a second peak is seen at 20 to 30min, which is attributed to thede novosynthesis of insulin by the beta cells. This peak has not been ...

Upon stimulation by thyroid-stimulating hormone (TSH), the thyroid produces two main hormones: thyroxine (T4), the major form of thyroid hormone in the blood, and triiodothyronine (T3), the active hormone (three to four times more potent than T4), which primarily regulates the metabolic...
Objective:Verifying the association between glycemic fluctuation and GH response in the glucagon stimulation test. Basal evaluation of growth hormone (GH) has poor diagnostic accuracy due to its pulsatile secretion. GH-stimulation tests are used for an adequate evaluation of somatotrophic axis. Various...

GH-stimulation tests are used for an adequate evaluation of somatotrophic axis. Various stimuli can be employed, among them glucagon, which has an elusive mechanism of action. Since hypoglycemia reportedly occurs during the test, investigation of its role as a stimulus to GH release is granted....
Glucagon stimulation testGrowth hormone deficiencyInsulin-like growth factor-IThe accuracy of the stimulation test () in diagnosing adult GH deficiency (GHD) has recently been questioned. Because pegvisomant (PegV) increases endogenous GH , we hypothesized that priming PegV to the (PegV-) 72 h ...
