(a) Photomicrograph of the kidney sections of the control groups (fed only water and rat chow). Blue line marked A shows the renal cortex and red line marked B shows the renal medulla, with both showing normal histologic features of the kidney (×100) (H&E). (b) Photomicrograph of the kidney sections of the control group. Blue arrows marked P show normal proximal tubules. Red arrows marked A show arterioles. Green arrows marked G indicate the glomeruli (H&E; ×100).
