Table 2 Characteristics of gastric and intestinal contractions during infusion of placebo and ghrelin in nine healthy volunteers.
| Variable | Placebo | Ghrelin | p Value |
|---|---|---|---|
| Stomach | |||
| No of contractions | 35 (4) | 46 (5) | 0.04 |
| Contraction amplitude (mm Hg) | 32 (4) | 53 (6) | 0.004 |
| Duration of contractions (s) | 21 (2) | 30 (4) | 0.03 |
| Motility index (min×mm Hg) | 3.5 (0.2) | 4.4 (0.4) | 0.01 |
| Small bowel | |||
| No of contractions | 29 (5) | 56 (9) | 0.03 |
| Contraction amplitude (mm Hg) | 33 (4) | 37 (5) | 0.5 |
| Duration of contractions (s) | 16 (2) | 22 (5) | 0.3 |
| Motility index (min×mm Hg) | 3.1 (0.3) | 4.2 (0.3) | 0.02 |
Results are mean (SEM).
Characteristics of contractions were measured at the most distal gastric and the most distal small intestinal channel; motility index is shown as average per minute.
