Intracerebroventricular Injection of Corticotropin-Releasing Factor Does not Alter Monoamine Content of the Paraventricular Nucleus of the Hypothalamus in Neonatal Chicks
Intracerebroventricular (i.c.v.) injection of corticotropin-releasing factor (CRF) on monoamine contents of the paraventricular nucleus of the hypothalamus (PVN) was investigated in neonatal chicks. The PVN was isolated from the brains of neonatal chicks 15 minutes after the i.c.v. administration of 0, 0.01, 0.1 or 1μg of CRF. The concentrations of noradrenaline, adrenaline, dihydroxyphenylacetic acid, dopamine, 5-hydroxyindole-3-acetic, homovanillic acid and 5-hydroxytryptamine were determined. The monoamines and their metabolites showed some alterations, but the differences were not significant among all treatments. The results suggested that CRF did not affect the monoamine contents of the PVN in the neonatal chick
