The effect of vasoactive substances on the circulation and glucose absorption of an isolated jejunal loop in the dog.

Abstract

The effects of vasoactive substances—histamine, epinephrine, and acetylcholine—on the circulation and glucose absorptive capacity of an in-vivo isolated jejunal loop were examined by functional and morphologic methods. These investigations furnish data for the existence of functioning arteriovenous connections in the small intestine of the dog.
