TEM pictures of the kidney. A These TEM pictures of the kidney’s proximal tubules represent typical endothelial cell lining. The cell has a rounded nucleus (N), an abundant Bruch border (B), basal infoldings (B), extensive mitochondria (M), lysosomes (L), and endocytic vesicles (Vc). B The diseased group shows distorted nuclei, irregularly distributed mitochondria, more frequent lysosomes, and irregular basal infoldings. C The nano-treated group shows recovery of the mitochondria, which appear more frequent. Lysosomes and endocytic vesicles are less numerous. D The composite group is close to the nano group
