Abstract：
:The cardiovascular and pulmonary responses to vasoactive intestinal contractor (VIC) were compared with those of endothelin (ET)-1, ET-2, ET-3 and sarafotoxin 6b (S6b) and the mechanism by which ET-1 alters vascular resistance was investigated in the hindquarters vascular bed of the cat. In a manner similar to ET-1 and ET-2, VIC at a dose of 0.3 nmol/kg i.v. produced increases in pulmonary arterial pressure (PAP) and biphasic changes in systemic arterial pressure (AP), systemic vascular resistance (SVR) and pulmonary vascular resistance (PVR). The biphasic changes were characterized by initial decreases followed by increases. In contrast, ET-3 and S6b at doses of 0.3 nmol/kg i.v. produced mainly decreases in AP and SVR, increases in PAP, and biphasic changes in PVR. A monocyclic ET-1 analog and the ET-1 C-terminal hexapeptide fragment produced no effect on AP, SVR, PAP and PVR at doses of 30-100 nmol/kg i.v. ET-1 at a dose of 0.3 nmol i.a. produced a biphasic change in hindquarters perfusion pressure. The initial vasodilation and secondary vasoconstriction were not modified by a variety of blocking agents, whereas the vasoconstrictor response was significantly reduced by infusion of nimodipine, a calcium entry blocking agent. Results of the present study indicate that VIC, a peptide specific to the mouse gastrointestinal tract, elicits cardiovascular responses that are similar to those elicited by ET-1 and ET-2. The present results indicate that responses to these novel peptides are complex and while the mechanism of action remains uncertain, these data indicate that structural differences among the peptides confer differences in biological activity.
