Circulatory Disturbances Produced by Acute Intestinal Distention in the Living Animal

The Influence 0f Rhythmic and Tonic Contraction 0f the Small Intestine on Blood Flow Through the Intestinal Segment

“…According to NOER et al (1951), in the small intestine of the rabbit, blood capillaries could be occluded at 30-40mmHg of extravascular pressure produced by mechanical compression. Mechanical occlusion of the blood flow was also observed in the small intestine by DRURY et al (1929-30), OKAE (1935), andYAGA-SAKI andYANAGIYA (1966).…”

Relation of Intestinal Motility to Venous Outflow and Saturation of Blood O2 Through Mesenteric Blood Vessels

“…According to NOER et al (1951), blood capillaries of the small intestine of rabbits could be occluded by extravascular pressure of 30-40 mmHg (408-544 mmH2O). Mechanical occlusion of blood flow was also observed in the small intestine by DRURY et al (1929-30), OKAE (1935), andYAGASAKI andYANAGIYA (1966).…”

Gastrointestinal circulation and motor function

“…Noer et al (137) observed the vascular event occurring within the gut wall during luminal distension in rabbits and dogs with a wide-field binocular microscope placed above the serosa. Distension interrupted the blood flow through different segments of the microcirculation in a uniform order, the first change occurring in the venules (Fig.…”
