Histological examinations of renal tissues were conducted in rats. Pathological changes of kidney were evaluated by H&E, PAS, and Masson Trichrome staining (a), (black arrows indicate vacuolation of tubular epithelial cells, and arrowheads indicate cylinder in H&E staining). Semiquantitative analysis of PAS and Masson Trichrome staining was conducted as previously described (b) (, versus control group, # versus DN group).
