1. Colonic transit time Colonic transit time was assessed by means of radioopaque Markers. 2. Colonic transit time was assessed by means of radioopaque markers. 3. Colonic transit time was significantly longer in the patients with cardiovascular autonomic neuropathy. 4. Information concerning motility of the entire colon has been obtained by indirect measures such as the movement of radioopaque markers or barium to assess colonic transit time. 5. Formulae have been devised to measure segmental colonic transit with radio-opaque shapes. 6. Serotonin, at the dose that accelerated ICJ transit, did not significantly alter colonic transit or ileal fluid transport. 7. Colonic transit was similarly assessed with the four colonic segments and effluent as the fifth segment. 8. Intra-aortic bethanechol significantly accelerated colonic transit. |
