Influence of dietary salt intake on the response of isolated perfused mesenteric veins of the dog to vasoactive agents.

Background: Previous work has established that a high dietary salt intake results in enhanced arterial vasoconstrictor responses to stimulation with agonists. This investigation was designed to investigate the effects of dietary salt on the responses of isolated capacitance vessels (third order mesenteric veins).

Methods: Dogs were fed diets containing low, intermediate, and high levels of dietary salt (0.
