The Synergistic Effects of His-D-Trp-Ala-Trp-D-Phe- Lys-NH<sub>2</sub>on Growth Hormone (GH)-Releasing Factor- Stimulated GH Release and Intracellular Adenosine 3',5'-Monophosphate Accumulation in Rat Primary Pituitary Cell Culture
His-D-Trp-Ala-Trp-D-Phe-Lys-NH2 (GHRP-6) stimulated GH release from rat primary pituitary cells in a time- and dose-dependent manner. Stimulation was observed after a 15-min, bu...
