Figure 10: Hematoxylin and eosin stained renal sections of the normal control group showing normal glomeruli and tubules (A, x200). Kidney sections from diabetic control group showing: severe hydropic degeneration in tubules (B, x400), vascular congestion and enlargementin the glomeruli with marked enlarged congested capillary tuft of glomeruli(C, x400). Kidney sections from steviatreated group showing improvement of all the renal injuries with mild glomerular enlargement, mild tubular degeneration and mild vascular congestion (D, x400). Kidney sections from glimepride treated group showing mild improvement of the renal injuries with moderate hydropic degeneration of the tubules and vascular congestion (E, x400). Kidney sections from glimepride and stevia treated group showing marked improvement of all the renal injuries with only mild vascular congestion (F, x400).
