Histopathological examination of kidney tissues. A Sham group, normal histology of renal tubules (blue arrows). B IRI group, renal tubules with score 4 damage. Cellular swelling increased cytoplasmic eosinophilia (black arrows), eosinophilic cast (blue arrows) & hemorrhage (red arrow). C DMSO group, renal tubules with score 4 damage. Cellular swelling increased cytoplasmic eosinophilia (black arrows). D Resveratrol group, renal tubules with score 2 damage. Cellular swelling increased cytoplasmic eosinophilia, involving 40% of the examined tubules (black arrows) and normal tubules (blue arrows). (H&E x400)
