(A) Hematoxylin and eosin staining; (B) Kidney injury scores; (C) BUN concentrations; (D) Serum creatinine concentrations. Blue arrows indicate tubular necrosis, red arrows indicate inflammatory cells, and black arrows indicate cell swelling and cytoplasm rarefaction. n=6 per group. Data are shown as the mean ± SEM. In (C) and (D), significance was calculated by one-way ANOVA with Tukey’s post hoc test, *: P<0.05.
