Immunohistochemical Studies on Galectin Expression in Colectomised Patients with Ulcerative Colitis

Figure 1

Illustration of the histological features for inflammatory grading of UC colon mucosa according to [17]. Top panel (a) shows a haematoxylin-eosin stained colon section from a patient with severe inflammatory activity (Table 1, patient 11, left colon). Below are shown magnifications of three selected areas illustrating cryptitis (panel (b), marked with black arrows), abscess (c), and an ulceration (d) all present in close proximity to each other. Bar in (a) = 2 mm, (b) = 50 μm, (c) = 100 μm, and (d) = 1 mm. Note that the sizes of biopsies obtained by endoscopy usually are 3-4 mm.
