effects of opioid peptides on immunoreactive corticotropin-releasing factor ( i-crf ) release from the rat hypothalamus were examined using a rat hypothalamic perifusion system and a rat crf ria in vitro . beta-endorphin ( 0.3 - 30 nm ) , dynorphin ( 0.3 - 30 nm ) and fk 33-824 ( 1 - 10 microm ) suppressed basal i-crf release in a dose-dependent fashion .
