Protocol
Rats[1]
Male albino Wistar rats (250-350 g) are used in the assay. Following an equilibration period of 45 min, the vasoactive effect of Adrenomedullin (1-50), rat, rADM (11-50), acetylcholine (ACh), and bradykinin (BK) is evaluated. The perfusion pressure on both sides of the mesenteric circulation is increased by infusing either a sympathomimetic, methoxamine (100 μM), on the arterial side or a thromboxomimetic, U46619 (0.5 μM), on the venous side. When a plateau is reached, the agents (Adrenomedullin (1-50), rat, etc.) are administered by bolus injections (1 to 45 μL). Vasodilator responses are expressed as percent reduction of induced tone on both sides of the mesenteric vasculature. In some experiments, the effects of the CGRP1 receptor antagonist hCGRP8-37 and of the nitric oxide synthase inhibitor L-NAME are evaluated. They are infused 15 and 30 min, respectively, before the administration of the agonists[1].
