Figure 11: Immunohistochemistry of eNOS: kidney sections from the normal control group showing week to moderate expression in endothelial cells of the glomeruli and peritubular capillaries (A, x400). Sections from the diabetic group show strong expression in endothelial cells of the glomeruli, peritubular capillaries and the proximal convoluted tubules (B, x400). Sections from stevia treated group showing week expression in the glomeruli, peritubular capillaries and the proximal convoluted tubules(C, x400). Glimepiride treated group showing moderated expression in the glomeruli, peritubular capillaries and the proximal convoluted tubules (D, x400). Glimepiride and stevia treated group showing week expression in the glomeruli, peritubular capillaries and the proximal convoluted tubules (E, x400).
