title: The effectiveness of a synthetic vasopressin analogue as a vasoconstrictor.
abstract: The effectiveness of a synthetis vassopressin analogue, ornithine-8-vasopressin (POR-8), as a vasocontrictor was tested in the superficial vessels of the rabbit ear. When compared to a control of normal saline and a standard of a dilute solution of epinephrine in lidocaine, POR-8 in saline is more effective than POR-8 in lidocaine, and is comparable in its effectiveness to the epinephrine solution.
