Photomicrographs of semithin sections of rat kidney tissue. a–c Sections in CA group showing some degenerated epithelial cells of the proximal tubules with a high degree of cytoplasmic vacuolization (thin arrows), destructed of the apical brush border (asterisk), necrosis of some nuclei (arrowhead), as well as a highly vascular congestion (VC) and interstitial infiltration (inf) are present. d The section in CA + FU group showing proximal tubules with mostly intact epithelial lining and brush border (arrows) and a normal appearance of vessels (v).
