Representative photomicrographs of anti-TNF-α immunohistochemistry-stained rat pancreatic Sects. (400x). A The control group shows negative immunostaining of β cells with TNF-α. B & C The groups STZ-30 and STZ-30-Cap exhibit moderate TNF-α immunostaining in β cells. D Group STZ-40 exhibits moderate TNF-α immunostaining. E Group STZ-40-Cap demonstrates strong TNF-α immunostaining of β cells. F STZ-50 illustrates strong TNF-α immunostaining of β cells. G STZ-50-Cap exhibits intensive immunostaining of β cells with TNF-α. H Histogram illustrating optical density of anti-TNF-α immunostained sections. * denotes significant difference compared to control, # denotes significant difference compared to STZ-30, $ denotes significant difference compared to STZ-30-Cap, € denotes significant difference compared to STZ-40, ¥ denotes significant difference compared to STZ-40-Cap, and @ denotes significant difference compared to STZ-50.
