Excessive glucocorticoid concentrations are well recognized inhibitors of linear growth, due in part to their suppression of GH secretion. The mechanism of this inhibition has been unclear, especially since glucocorticoids enhance the in vitro GH response of pituitary cells to GH-releasing hormone (GHRH). We investigated the possibility that hypothalamic(More)
Suppressed pulsatile GH secretion in food-deprived rats has been hypothesized to be due to an increase in hypothalamic somatostatin secretion. We investigated this hypothesis and the role of GHRH in regulating GH secretion during food deprivation using two different models. In experiment one, rats were food deprived for 72h during which time they received a(More)
