Abstract/OtherAbstract:
BACKGROUND: The timing of the migrating motor complexes (MMC) at food intake may influence gastric emptying and release of regulatory hormones. This report studies the relationships between phases I (motor quiescence) and II (intermediate frequency contractions) of MMC and prandial gut hormone response. MATERIALS AND METHODS: Seven fasting volunteers ingested a meal during phase I or II of MMC verified by manometry, using paracetamol as a marker for gastric emptying. Blood was sampled before, during and 210 min after food intake for analysis of ghrelin, motilin, insulin and paracetamol. RESULTS: The basal level of ghrelin during phase I was 127.5 +/- 25.4 pmol L(-1) and during phase II was 132.4 +/- 24.8 pmol L(-1). After food intake during phase I, ghrelin fell to 77.2 +/- 10 pmol L(-1); in phase II it fell to 82.7 +/- 17.8 pmol L(-1) within 60 min and returned to baseline levels after 120 min. Baseline levels of motilin were 16 +/- 2 pmol L(-1) and 18 +/- 3 pmol L(-1) during phases I and II, respectively. After food, motilin decreased to 8.5 +/- 0.7 pmol L(-1) and 8.7 +/- 1.0 pmol L(-1) within 60 min and returned to baseline after 90 min. Insulin levels in phases I and II were 8.1 +/- 1.2 mU L(-1) and 8.6 +/- 0.7 mU L(-1), respectively, reaching 138.9 +/- 35.6 mU L(-1) and 167.4 +/- 30.0 mU L(-1) at 45 min postprandially. CONCLUSIONS: The nutritional status of the gastrointestinal tract at food intake had only a limited impact on plasma ghrelin. After food intake, plasma ghrelin drops, similar to motilin, and resumes preprandial levels within 120 min.
