Action of XXXX on the mesenteric vascular bed of the @entity235 .

@entity1169 @entity1522 @entity34776 @entity235 @entity450 @entity551 @entity73006
@entity73006 , a linear peptide of 40 @entity1522 , produced @entity551 when administered intravenously to anesthetized @entity235 . Diastolic pressure was always more affected than systolic pressure. Aortic blood flow and venous return both increased to the same extent. The mechanism of the @entity551 response was mainly, if not exclusively, due to dilatation of the superior and inferior mesenteric arteries. Intravenous infusion of @entity73006 in doses ranging from 3 to 10 ng . kg-1 . min-1 produced a dose-related increase of mesenteric blood flow up to 400% control values. @entity450 and colon was increased, while blood flow in muscle was unaffected or slight decreased. The mesenteric vasodilator response was not prevented by adrenergic or muscarinic receptor blockade. The @entity551 response was more marked and sustained in @entity34776 - @entity1169 treated @entity235 .
