Photomicrograph of the renal cortex of iNOs immunostaining showing: (A) group I have a weakly positive reaction at the cytoplasm of glomeruli capillary endothelium cells and a faint positive reaction in the cytoplasm of the tubular cells. (B) group II has a strong positive reaction at the cytoplasm of glomeruli capillary cells and tubular cells. (C) group III has a moderately positive reaction at the cytoplasm of glomeruli capillary cells and tubular cells. (D) group IV has a mild positive reaction at the cytoplasm of glomeruli capillary cells and tubular cells. (E) group V has a faint positive reaction at the cytoplasm of glomeruli capillary cells and tubular cells (×400).
