Increased immunostaining for T cells and macrophages/DCs in T12 surveillance biopsies with IF+i by Banff '97 criteria. (A and B) Results are shown graphically for digital image analysis of tissue sections from T12 surveillance biopsies stained by immunoperoxidase for T cells (CD3; A) and macrophages/DCs (CD68; B). Sections were stained from groups categorized by Banff '97 scoring as having normal histology (Normal), IF alone, and IF+i. Results are shown as cells/mm² of the total cortical interstitial space. ○, results for individual biopsies; thick bars, group mean results. P values indicate results of between-group comparisons by unpaired t test.
