Systemic and regional hemodynamic effects of intravenously injected calcitonin gene-related peptide (CGRP), 220 and 650 pmol, were compared in nine Wistar-Kyoto (WKY) and nine spontaneously hypertensive rats (SHR). CGRP (higher dose) reduced mean arterial pressure (from 135 +/- 2 to 83 +/- 2 and from 179 +/- 4 to 116 +/- 3 mmHg; P less than 0.01, each, in WKY and SHR, respectively) through a fall (-38 +/- 4 and -40 +/- 3%; P less than 0.01) in total peripheral resistance associated with an unchanged cardiac output and an increased heart rate. The decreases in arterial pressure and total peripheral resistance were not different between these two strains. Of particular significance were the highly selective reductions in organ vascular resistances, being greatest in the cutaneous (-78 +/- 3 and -67 +/- 4%) and gastric (-80 +/- 3 and -84 +/- 2%) circulations in WKY and SHR, respectively (P less than 0.01). Reduction in coronary, cerebral, and hepatic vascular resistances, although significant (P less than 0.05, at least), were only moderately reduced compared with the two former circulations. These effects were similar in WKY and SHR and demonstrate that CGRP is a highly selective and potent natural vasodilating peptide that has the most striking effects in skin and stomach, suggesting possible modulator functions in regulating certain regional hemodynamics.
