Effect of central sympathectomy on gastric and small intestinal myoelectric activity and plasma motilin concentrations in the dog. 1985

G L Telford, and V L Go, and J H Szurszewski

Using a canine model, we studied fed and fasting gastric and small intestinal myoelectric activity and plasma motilin concentrations before and after transection of the spinal cord between the second and third thoracic segments. In sham-operated dogs, migrating complexes returned to normal by the second day after operation. Immediately after spinal cord transection, migrating complexes cycled in jejunum and ileum but not in the stomach and duodenum. After 11 and 15 days, migrating complexes returned to the duodenum and stomach, respectively. Plasma motilin concentrations did not cycle in animals without duodenal migrating complexes but returned to a normal cyclical pattern when duodenal migrating complexes returned. Feeding interrupted migrating complexes after cord transection and sham operation. The data observed in animals after 15 days suggest that myoelectric activity in fasted dogs and conversion of the fasted to the fed state of myoelectric activity are not under the control of supraspinal, sympathetic pathways.

UI MeSH Term Description Entries
D007082 Ileum The distal and narrowest portion of the SMALL INTESTINE, between the JEJUNUM and the ILEOCECAL VALVE of the LARGE INTESTINE.
D007421 Intestine, Small The portion of the GASTROINTESTINAL TRACT between the PYLORUS of the STOMACH and the ILEOCECAL VALVE of the LARGE INTESTINE. It is divisible into three portions: the DUODENUM, the JEJUNUM, and the ILEUM. Small Intestine,Intestines, Small,Small Intestines
D007583 Jejunum The middle portion of the SMALL INTESTINE, between DUODENUM and ILEUM. It represents about 2/5 of the remaining portion of the small intestine below duodenum. Jejunums
D009037 Motilin A peptide of about 22-amino acids isolated from the DUODENUM. At low pH it inhibits gastric motor activity, whereas at high pH it has a stimulating effect.
D004285 Dogs The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065) Canis familiaris,Dog
D004386 Duodenum The shortest and widest portion of the SMALL INTESTINE adjacent to the PYLORUS of the STOMACH. It is named for having the length equal to about the width of 12 fingers. Duodenums
