Colonic motility.

Bowel Motility and Colonic Cancer

hilarity and movement (presumably including eye movement) during the compression phase due to the combined effects of warmth and nitrogen narcosis, thus assisting the flow of nitrogen-laden tears between the lens and cornea, while during decompression the chamber was, as is usual, rather cold and foggy, with the subjects relatively immobile, thus minimizing any flow of tears which might have he...

Colonic motility: practice or research?

5-Hydroxytryptamine4 receptor agonists and colonic motility.

5-Hydroxytryptamine (5-HT) released from enterochromaffin cells regulates gastrointestinal function in either an excitatory or inhibitory manner. 5-HT(3) and 5-HT(4) receptors in the gut have been the focus of clinical studies on the management of gastrointestinal motility disorders. 5-HT stimulates intestinal propulsive reflexes through 5-HT(4) receptors. 5-HT(4) receptor agonists can stimulat...

Luminally released serotonin stimulates colonic motility and accelerates colonic transit in rats.

Enterochromaffin (EC) cells of the epithelial cells release 5-HT into the lumen, as well as basolateral border. However, the physiological role of released 5-HT into the lumen is poorly understood. Concentrations of 5-HT in the colonic mucosa, colonic lumen, and feces were measured by HPLC in rats. To investigate whether intraluminal 5-HT accelerates colonic transit, 5-HT and (51)Cr were admini...

Electric activity spreads in the colonic longitudinal but not the circular musculature. Role in colonic motility.

The colon has a circular and longitudinal muscle layers and possesses an electric activity. The current study investigated the spread of this electric activity in the colonic musculature. The tests were performed in 16 patients (mean age 40.6 +/- 10.8 SD years, 10 men, 6 women) during operative correction of their incisional hernias in the anterior abdominal wall. Three electrodes were applied ...
