Figure 3

The morphologic changes of colon in four groups. (a, e, and i) Control group: showing normal colonic mucosa (H&E staining, 4 ×, 10 ×, 20 ×). (b, f, and j) Model group: showing massive ulcers, changes in crypt structure and loss of inflammation (H&E staining, 4 ×, 10 ×, 20 ×). (c, g, and k) SASP group: showing marked reduction of inflammation and nearly intact mucosa (H&E staining, 4 ×, 10 ×, 20 ×). (d, h, and l) BZYQ group: showing marked reduction of inflammation and nearly intact mucosa (H&E staining, 4 ×, 10 ×, 20 ×).
