histamine is very short lived...about 6 min and causes dilation by endothelial cell contraction...Brady o the other hand is about 30 min and cases separation of tigh junctions and free passage of vascular fluid in to interstititum.

bradykinin is correct, key point to identify is inactivation by peptidases [ACE]

histamine undergoes inactivation by MAO and DAO!
