GH-releasing peptide (GHRP-6)-induced ACTH release in patients with Addison's disease: Effect of glucocorticoid withdrawal
(Editrice Kurtis S R L, 2003-02-01)
GH releasing peptide (GHRP-6) is a synthetic hexapeptide with potent GH releasing activity both in man and in animals. This peptide is also able to stimulate ACTH and cortisol (F) release. It has been suggested that the ...
Effect of one month ketoconazole treatment on GH, cortisol and ACTH release after ghrelin, GHRP-6 and GHRH administration in patients with cushing s disease
(Sociedade Brasileira de Endocrinologia e Metabologia, 2007-10-01)
GH responses to ghrelin, GHRP-6, and GHRH in Cushing s disease (CD) are markedly blunted. There is no data about the effect of reduction of cortisol levels with steroidogenesis inhibitors, like ketoconazole, on GH secretion ...
Different effects of growth hormone releasing peptide (GHRP-6) and GH-releasing hormone on GH release in endogenous and exogenous hypercortisolism
(Wiley-Blackwell, 1997-06-01)
OBJECTIVE Chronic hypercortisolism is associated with decreased OH responsiveness to GHRH, GHRP-6 is a synthetic hexapeptide that releases GH in several species, including man, As GHRH and GHRP-6 apparently stimulate GH ...
Decreased ghrelin-induced GH release in thyrotoxicosis: comparison with GH-releasing peptide-6 (GHRP-6) and GHRH
(Springer, 2007-03-01)
In thyrotoxicosis GH response to several stimuli is impaired, but there is no data on ghrelininduced GH release in these patients. Ghrelin is a potent GH secretagogue and it also increases glucose levels in men. the aim ...
Growth hormone responses to GH-releasing peptide (GHRP-6) in hypothyroidism
(Wiley-Blackwell, 1997-03-01)
OBJECTIVE Both spontaneous and stimulated GH secretion are reduced in patients with hypothyroidism. the mechanisms involved in these alterations are not yet fully understood, GHRP-6 is a synthetic hexapeptide that releases ...
Glicocorticóides e hormônio de crescimento (GH): efeito da administração aguda de dexametasona e do hipocortisolismo sobre a resposta do GH ao GHRP-6 (GH-releasing peptide)
(Universidade Federal de São Paulo (UNIFESP), 1999)
Estudo 1- Nosso estudo demonstrou que a administracao oral de dexametasona na dose de 4 mg, 3 1/2horas antes, aumenta a resposta do GH ao GHRP-6. Isto pode sugerir que a dexametasona e o GHRP-6 atuam em locais distintos ...
Acute dexamethasone administration enhances GH responsiveness to GH releasing peptide-6 (GHRP-6) in man
(Wiley-Blackwell, 1999-10-01)
OBJECTIVE Acute administration of glucocorticoids stimulates GH secretion probably by a decrease in hypothalamic somatostatin release. GHRP-6 is a synthetic hexapeptide that increases GH secretion by a mechanism of action ...
Efeitos da ghrelina, GHRP-6 e GHRH sobre a secreção de GH, ACTH e cortisol em pacientes com diabetes mellitus tipo 1
(Universidade Federal de São Paulo (UNIFESP), 2009-06-24)
In type 1 diabetes mellitus (T1DM), GH responses to provocative stimuli are normal or exaggerated while the hypothalamic-pituitary-adrenal axis has been less studied. Ghrelin is a GH-secretagogue which also increases ACTH ...
Ghrelina e secretagogos do hormônio de crescimento (GHS): modulação da secreção do hormônio de crescimento e perspectivas terapêuticas
(Sociedade Brasileira de Endocrinologia e Metabologia, 2008-07-01)
Growth hormone-releasing hormone (GHRH) and somatostatin modulate growth hormone (GH) secretion. A third mechanism was discovered in the last decade, involving the action of growth hormone secretagogues (GHS). Ghrelin, the ...
Influência dos glicocorticóides sobre o eixo somatotrófico
(Sociedade Brasileira de Endocrinologia e Metabologia, 2003-08-01)
GH secretion is modulated by a complex interplay between two hypothalamic factors, GHRH (growth hormone-releasing hormone) and somatostatin (SRIF). More recently, a third physiological mechanism mediated by GHS (growth ...
