| Outline of Final Research Achievements |
The aim of the present study was to clarify the relationship between hypothalamic dopamine (DA) and salsolinol (SAL) for the secretion of prolactin (PRL) in ruminants. The results obtained from the present studies indicate that the mechanisms underlying the SAL-induced PRL response differ from those of thyrotropin-releasing hormone (TRH), and suggest that the extracerebral DA might be associated in part with the modulation of SAL-induced PRL secretion in goats. The results also indicate that the hypothalamic DA is profoundly involved in the mechanisms of SAL-induced PRL secretion, and suggest that DA and its synthesis by tyrosine hydroxylase is associated in part with SAL-induced PRL secretion.
