Figure 5 (a) Kidney of normal rats showing normal histological structures of glomeruli and tubules, (b) urolithic control rats showing extensive tubular dilatation associated with presence of abundant prominent refractile oxalate crystals in the lumen of the renal tubules, (c) cystone-treated rats showing mild tubular dilatation, (d) Solanum nigrum (200 mg/kg)-treated rats showing focal vacuolar degeneration of renal tubular epithelium associated with mild tubular dilatation, and (e) Solanum nigrum (400 mg/kg)-treated rats showing mild granular degeneration of renal tubular epithelium (hematoxylin and eosin, ×40).
