Figure Lengend Snippet: Cardiovascular responses to CGRP at 0.1 nmol kg−1 (n=8) or 1 nmol kg−1 (n=6) in the absence or presence of ADM (22-52) (500 nmol kg−1 h−1) in conscious Long Evans rats. The mesenteric vasoconstrictor effect of the higher dose of CGRP was enhanced in the presence of ADM (22-52), possibly due to the mesenteric vasodilator influence of the latter. Values are mean and vertical bars show s.e.mean.
