Figure 2.
Histopathological changes in the kidney tissues of mice treated with VCM and/or VC. (A) HE-stained mouse kidney sections from the control group (top left), VC group (top right), VCM group (bottom left), and VCM + VC group (bottom right), 40× magnification. (B) The kidney tubular injury score in each group. Tubular injury was scored by calculating the percentage of tubules that displayed tubular epithelial cell degeneration (necrosis, vacuolization, and brush border loss), tubular alterations (dilatation, atrophy, and casts), and interstitial inflammatory cell infiltration as 0, none; 1, injury percentage ≤25%; 2, injury percentage 26–50%; 3, injury percentage 51–75%; 4, injury percentage ≥76%. The results are presented as group means ± SD (n=7 mice/group). #, P<0.05 compared to the VCM group. VCM, vancomycin; VC, vitamin C; HE, hematoxylin and eosin; SD, standard deviation.
