Potentiation of bradykinin effects and inhibition of kininase activity in isolated smooth muscle.

abstract：:The area postrema (AP) is one of the circumventricular organs of the brain and as such it is highly vascular and lacks the normal blood-brain barrier. Anatomical tracing studies have demonstrated afferent projections to AP originating from the paraventricular nucleus, lateral parabrachial nucleus (l-PBN), nucleus trac...
