Figure 1 (A) Macroscopic damage scores for the ileum were significantly higher in guinea pigs treated with TNBS 3 days previously compared to saline‐treated controls. *p<0.05 (mean (SE)). However, there was no detectable change in damage score of the colons from animals with TNBS‐induced ileitis. (B) MPO activity, a measure of neutrophil infiltration, was similar in the colon of animals with TNBS‐induced ileitis when compared to the saline‐treated controls. (C) TNBS ileitis animals initially lost weight and regained weight at a slower rate than controls. *p<0.05 (mean (SE)).
