Light microscopic images of cardiomyocytes (A, B), aorta (C, D), kidney (E, F) and hepatocytes (G, H) in control (A, C, E, G) and CM-treated (B, D, F, H) rats. (A, B) arrows, densely stained linear profiles; arrowheads, intercalated disks. (C, D) lu, lumen; i, intima; m, media; arrows, elastic lamina. (E, F) arrows, glomerular (g) capillary lumens; +, renal tubules/collecting ducts; asterisks, blood vessels. (G, H) arrows, nuclei of hepatocytes more closely located; asterisks, hepatic blood capillaries. Scales, 50 μm.
