Photomicrographs of renal sections stained with Masson’s trichrome of the different groups. A: Normal control, showing normal glomeruli (GL) in the cortical area, with intact Bowman’s capsule (BM) and proximal convoluted tubules. B: TAA group, showing renal cortical tissue with swollen and necrotic tubular cells, C: VN100 group, showing mild tubular epithelial changes in renal cortical tissue. D: VN300 group, showing renal cortical tissue with both GL and tubules appearing normal. Bar = 100 μm.
