Assessment of growth by measurement of bowel weight, mucosal weight, and enzyme activity of lengthened (off tension), unlengthened, and in situ bowel
| Gross characteristic | Lengthened | Unlengthened | In situ bowel | |||
| Length at day 0 (mm) (n = 40) | 7.6 (1.0) | 7.7 (1.1) | 10 (0.0) | |||
| Length at day 30 (mm) (n = 40) | 19 (2.3) | 8.2 (1.3)* | 11 (0.5) | |||
| Bowel weight (mg) (n = 10) | 314 (145) | 98.6 (62.5)* | 67.5 (10.4) | |||
| Mucosal weight (mg) (n = 10) | 60.9 (26.6) | 27.4 (23.1)* | 23.5 (7.34) | |||
| Enzyme activity | Total (n = 10) | Per mg (n = 10) | Total (n = 10) | Per mg (n = 10) | Total (n = 10) | Per mg (n = 10) |
