“…a). The transient dilator response to the intra-arterial injection of contrast medium (LINDGREN & TORNELL 1958, BOIJSEN et colI. 1971, LEWIS et colI.…”
The dilatation of major arteries following early after extensive soft tissue trauma was demonstrated angiographically not to be affected by pharmacologic or mechanical contractile stimuli. The proximal spread of the dilatation was not abolished by the division and a reanastomosis of the vessel before the trauma. These results suggest loss or impairment of the contractile ability of the major arteries following early after the trauma.

“…The same feeling can be provoked by a hypertonic saline solution (VAN DE BERG 1962). It is well known from experiments that all contrast media cause a vasodilatation of various vascular beds, the diatrizoate salts less than previously used media (SCHMIDT 1955, LINDGREN & TORNELL 1958, HOL 1960, KAGSTROM et coll. 1960).…”

“…The present series demonstrated the long transit times in the superior and inferior mesenteric vascular beds, which seemed to be caused by arteriolar constriction possibly followed by vasodilatation. The physiologic experiments with measurement of blood flow after injection of various contrast agents (LINDGREN & TORNELL 1958, KAGSTROM et coll. 1960 do not seem to have taken into account this first short constriction of the vessels, which is of fundamental importance in angiography.…”

“…Experimental investigations in animals have shown that an intraarterial injection of a contrast medium always produces vasodilatation, and thereby an increase in blood flow in the area in question (LINDGREN & TORNELL 1958, READ et coll, 1960, HILAL 1966. Some authors claim that injection of a contrast medium produces only vasodilatation (LINDGREN & TORNELL 1958, LINDGREN et coll.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
