Heat Shock Protein-70 immunoreactivity in the small intestinal mucosa. Microscopic images of the crypts and villi of the small intestinal mucosa after immunohistochemical staining for Heat Shock Protein-70. Panels a and b are from an ischaemic sample, c and d are from the reperfusion sample of the same horse, illustrating an increase in immunoreactivity. Representative examples of the stained enterocyte nuclei are marked (narrow arrow for weak stained nuclei, broad arrows for the intensely stained nuclei), the enterocyte cytoplasm shows a mild to moderate staining
