Cardiac lesions measured by transmission electron microscopy.

<p>A: NC group (n = 10). Note the regular membrane and intercalated disc between adjacent myocytes. B: MS group (n = 10). Interrupted capillary membrane, and derangement and increase of myofibers and mitochondria in cardiomyocytes were visible. Swollen mitochondria were shown by the arrows. C: MS+A group (n = 11). D: MS+H group (n = 11). Compared with MS group, the ultrastructural changes of drug-fed groups were obviously improved. Original magnification: ×10, 000.
