we conclude that prostaglandins ( especially pge2 ) can inhibit ( 1 ) the stimulated release of vasopressin when acting on vasopressin-containing nerve terminals of either neurosecretory system ( neurohypophysis , median eminence region ) , and ( 2 ) the secretion of beta-ei and , as can be inferred , alpha-msh , by a direct action on intermediate lobe cells .
