TL;DR: It is concluded that cytochrome P450 activity in the brain is very low, but that psychotropic drugs could undergo a local cerebral metabolism which could have pharmacological and/or toxicological consequences.
Journal ArticleDOI
Dopamine in plasma of lateral and medial hypophysial portal vessels: evidence for regional variation in the release of hypothalamic dopamine into hypophysial portal blood
TL;DR: It is suggested that topographic differences may exist in the release of PRL by cells of the pituitary gland as a consequence of uneven concentrations of dopamine in portal blood perfusing the lactotropes.
Journal ArticleDOI
An inhibitory role for morphine on the release of dopamine into hypophysial portal blood and on the synthesis of dopamine in tuberoinfundibular neurons
TL;DR: The intracerebroventricular administration of morphine to ovariectomized rats resulted in a marked decrease in the concentration of dopamine in plasma of hypophysial portal blood, supportive of the view that morphine inhibits both the release and synthesis of dopamine but is more effective in inhibiting the release than synthesis of serotonin.
Journal ArticleDOI
Dopaminergic neurons in the mediobasal hypothalamus of old rats: evidence for decreased affinity of tyrosine hydroxylase for substrate and cofactor
TL;DR: The effect of aging on the activity of tyrosine hydroxylase (TH) and on the number of TH-positive perikarya in the hypothalamus was studied in old and young female rats and it was concluded that the reduced TH activity in the MBH of old rats is due to a reduction in the affinity of TH for its substrate and cofactor.
Journal ArticleDOI
Estrogen alters the responsiveness of the anterior pituitary gland to the actions of dopamine on lysosomal enzyme activity and prolactin release.
TL;DR: It is suggested that the decrease in the responsiveness of the anterior pituitary gland to the actions of dopamine on lysosomal enzyme activity and PRL release that occurs between diestrus and estrus is estrogen mediated.
