Fig. 5. RES ameliorates renal morphological changes and reduces the infiltration of inflammatory cells in the kidney. Representative photographs of H&E-stained rat renal sections at a magnification of 200×. The groups were as follows: control group, hyperuricemia group (sham), hyperuricemia with low-dose RES, hyperuricemia with medium-dose RES, and hyperuricemia with high-dose RES. The blue arrows represent eosinophilic insoluble proteins; the black arrow represents salt crystals; and the green arrow represents edema of renal tubular epithelial cells.

RES, resveratrol; H&E, hematoxylin and eosin.
