Figure 6: Kidney histological analysis of mice exposed to diphenyl ditelluride 50 μmol/kg for 7 days. (a) Kidney section of control group showing conserved architecture of cortex with convoluted tubules outlined for a single layer of cuboidal cells and preserved glomeruli; kidney section of diphenyl ditelluride treated mice revealing (b) vacuolar degeneration represented for marked epithelial cells swelling of renal tubules; (c) hypertrophic tubules filled with eosinophilic homogeneous substance (cast proteinaceous) (arrow); and (d) presence of vascular congestion in cortical and medullar areas (circle) (H&E 10x). The picture is a representation of three independent experiments.
