title: Effects of hyper- and hypoprolactinemia on glutamate decarboxylase activity in medial basal hypothalamus of male rat.
abstract: Haloperidol, sulpiride, domperidone and apomorphine, drugs which influence dopamine (DA) receptors and in turn prolactin (PRL) secretion have been shown to induce parallel changes in medial basal hypothalamic (MBH) glutamate decarboxylase (GAD) activity and serum PRL levels. The possibility that PRL may be involved in the effects of the drugs on MBH GAD activity is suggested in view of the evidence that hypophysectomy completely prevents drug-induced MBH GAD activity changes and that hyperprolactinemia by anterior pituitary homograft results in a significant, although small, change in the enzymatic activity.
