(a) Immunohistochemical view (100× magnification) of normal colonic mucosa stained for heat shock protein (Hsp32). Scattered positive-staining (brown) cells are seen in the lamina propria. (b) Immunohistochemical view (100× magnification) of inflamed colonic mucosa from a patient with active ulcerative colitis (UC) stained for Hsp32. (c) Immunohistochemical view (100× magnification) of colonic mucosa from a patient with inactive UC stained for Hsp32. (d) Immunohistochemical view (250× magnification) of inflamed colonic mucosa from a patient with active UC stained for Hsp32. Positive-staining (brown) superficial and crypt epithelial cells, and lamina proprial inflammatory cells are seen
