Peptide staining enteroendocrine cell counts per 100 epithelial cells
| Controls | Initial | 6 weeks | 12 weeks | |
| n | 8 | 19 | 17 | 15 |
| 5-HT | 0.6 (0.2) | 7.0 (1.0)4-160 | 3.9 (0.5)4-160 4-151 | 3.2 (0.7)4-160 4-151 |
| n | 7 | 12 | NA | 10 |
| PYY | 2.4 (0.3) | 8.4 (1.6)4-160 | NA | 2.0 (0.4) |
ANOVA for repeated measures showed significant differences between initial, six, and 12 weeks for 5 hydroxytryptamine (5-HT) values , F=6.1, df 1,13, p<0.05.
↵4-160 Significant difference from control values, p<0.01.
↵4-151 Significant difference from initial value, p<0.05.
NB, note reduced numbers in peptide YY (PYY) analysis owing to lack of biopsy material.
