title: Melatonin inhibits prostaglandin E release from the medial basal hypothalamus of pinealectomized rats.
abstract: The effects of pinealectomy and of melatonin administration on prostaglandin E synthesis in the medial basal hypothalamus were studied in male rats. Melatonin treatment significantly decreased prostaglandin E release from the medial basal hypothalamus in pinealectomized rats. The results of the present study suggest that melatonin modulates hypothalamo-hypophyseal function, at least in part, via inhibition of hypothalamic prostaglandin synthesis.
