(Received October 26, 1990) Abstract The effect of cholecystokinin octapeptide (CCK-8) was studies on the release of growth hormone (GH) from perifused medial basal hypothalami (MBH) and/or adenohypophyses of goats in a sequential double chamber perifusion system. The mean GH concentrations in perifusion groups containing pituitary fragments alone with media containing 10-6, 10-7 and 10-8 M CCK-8 for 90 min significantly increased during the treatments by 76% (P
