Inhibition of ADH release in the rat by narcotic antagonists.

abstract：BACKGROUND/AIMS:Cervical stimulation induces a circadian rhythm of prolactin secretion and antiphase dopamine release. The suprachiasmatic nucleus (SCN) controls this rhythm, and we propose that it does so through clock gene expression within the SCN. METHODS:To test this hypothesis, serial blood samples were taken fr...
