Fig. 4. Renal histological morphology in the control and CIN models.
A. Histological examination of kidney tissue with hematoxylin and eosin staining. There is no obvious change in tubular cells of the glomerulus in the CIN group compared to the control. Magnification = × 20, scale bar = 50 µm. B. Analysis of morphology changes in the kidney using transmission electron microscopy. In the CIN model, more vacuoles and greater mitochondrial expansion are observed. Magnification = × 8000, scale bar = 5000 nm. CIN = contrast-induced nephropathy
