Effects of DHM on pathological changes in STZ-induced diabetic mice. (a) Representative images of myocardial tissue sections stained with hematoxylin and eosin ((a) first row, magnification = 400x); representative images of myocardial tissue sections stained with Masson's trichrome ((a) second row, magnification = 400x, yellow arrows indicate collagen deposition); representative transmission electron micrographs of left ventricular specimens ((a) third and fourth rows, magnification = 8200x and 26500x, red arrows indicate swollen mitochondria). (b) Quantification of fibrosis. The columns and error bars represent the means and SD (n = 6). ^∗P < 0.05 versus CON; ^#P < 0.05 versus CON + DHM; ^$P < 0.05 versus DM.
