Numbers of mast cells in inflamed but non-strictured and in strictured bowel of Crohn’s disease and numbers of mast cells in the ulcerative colitis compared with normal bowel
| Mucosa (cells/mm2) | Submucosa (cells/mm2) | Muscularis propria (cells/mm2) | |
|---|---|---|---|
| Inflamed but non-strictured bowel | 54.5 (16.1) | 55.0 (11.4)2-150 | 8.2 (2.4)2-150 |
| Strictured bowel | 69.2 (10.2)2-150 | 59.6 (8.3)† | 78.2 (6.3)† |
| Ulcerative colitis | 51.4 (7.1) | 29.4 (2.2) | 6.4 (2.7) |
| Normal control | 35.2 (3.8) | 24.4 (4.1) | 1.1 (0.6) |
Mast cell numbers were determined by tryptase staining in five adjacent microscope fields in the mucosa, the submucosa, and the muscularis propria at 200× magnification and normalised to 1 mm2. The results are expressed as mean (SEM).
