His-dTrp-Ala-Trp-dPhe,Lys-NH2(GHRP-6) is a synthetic compound that releases GH in a dose-response and specific manner in several species and that may well be related to an endogenous compound of similar structure. The aim of this study was to investigate the in vivo GH responses to GHRP-6 in pentobarbital anesthetized rats. Specifically and in order to(More)
In order to investigate the mechanisms involved in the in vivo Growth Hormone (GH) response to Neurotensin (NT) we assessed the influence of estrogen status as well as the effect of passive immunization with antisomatostatin and anti-Growth Hormone-Releasing Hormone (GHRH) on NT-induced GH secretion in pentobarbital anesthetized rats. We found that,(More)
Previous studies carried out in normal male or ovariectomized female rats have shown that bombesin plays an inhibitory role on growth hormone (GH) secretion. Since estrogens play an important role in the neuroregulation of GH secretion, we have studied the effects of bombesin on basal GH secretion and GH responses to GH-releasing hormone (GHRH) in untreated(More)
