Mechanism of Interdigestive Migrating Motor Complex

Migrating motor complex (MMC) is well characterized by the appearance of gastrointestinal contractions in the interdigestive state. This review article discussed the mechanism of gastrointestinal MMC. Luminal administration of 5-hydroxytryptamine (5-HT) initiates duodenal phase II followed by gastrointestinal phase III with a concomitant increase of plasma motilin release in conscious dogs. Duo...

Interdigestive migrating motor complex -its mechanism and clinical importance

Migrating motor complex (MMC) is well characterized by the appearance of gastrointestinal (GI) contractions in the interdigestive state. The physiological importance of gastric MMC is a mechanical and chemical cleansing of the empty stomach in preparation for the next meal. MMC cycle is mediated via the interaction between motilin and 5-hydroxytryptamine (5-HT) by the positive feedback mechanis...

Changing Interdigestive Migrating Motor Complex in Rats under Acute Liver Injury

Gastrointestinal motility disorder is a major clinical manifestation of acute liver injury, and interdigestive migrating motor complex (MMC) is an important indicator. We investigated the changes and characteristics of MMC in rats with acute liver injury. Acute liver injury was created by d-galactosamine, and we recorded the interdigestive MMC using a multichannel physiological recorder and com...

Gender influence on jejunal migrating motor complex.

The role of gender and the menstrual cycle in small bowel motility has not been clearly elucidated. Jejunal motility was recorded with a nasojejunal catheter incorporating five solid-state pressure transducers in ambulatory menstruating women and men of comparable age over 24 h. All women were studied twice, in the early follicular (early-F) and midluteal (mid-L) phases of the menstrual cycle, ...

Redefining the functional roles of the gastrointestinal migrating motor complex

17 During the fasting state the upper gastrointestinal tract exhibits a specific periodic 18 migrating contraction pattern which is known as the migrating motor complex (MMC). 19 Three different phases can be distinguished during the MMC. Phase III of the MMC is 20 the most active of the 3 and can either start in the stomach or small intestine. 21 Historically this pattern was designated to be ...
