Monoamines in tubero-hypophyseal structures of farm animals
Abstract:
Dopamine (DA) and 5-hydroxytryptamine (5-HT) were measured in several regions of the pituitary gland of Jersey steers, Soay ewes and two breeds of pigs. The glands were collected from animals which had not been stressed and the amine concentrations were comparable to those found previously in the pituitary glands of laboratory animals. Metabolites of both amines were present in the infundibulum, the pituitary stalk, the combined neural and intermediate lobe and the anterior lobe of all glands analysed indicating that the amines are being utilized in these structures under "near physiological" conditions.
