(a) Hematoxylin and eosin staining of the heart of rat of normal control group (hematoxylin-eosin, original magnification ×100). Hollow arrow indicates normal histoarchitecture of the heart. (b) Hematoxylin and eosin staining of the heart of rat of toxicant (fructose) control group (hematoxylin-eosin, original magnification ×100). Hollow arrow indicates lymphocytic infiltrate, and solid arrow indicates myocardial necrosis and severe myofibrillar loss. (c) Hematoxylin and eosin staining of the heart of rat of NAOE200 group (hematoxylin-eosin, original magnification ×100). Hollow arrow indicates splitting and swaying of myocardial fibers with moderate lymphocytic infiltrate around blood vessels. (d) Hematoxylin and eosin staining of the heart of rat of NAOE400 group (hematoxylin-eosin, original magnification ×100). The big hollow arrow indicates focal hyalinized area in myocardium, and the small arrow indicates lymphocytic infiltration. The rest of the myocardial fibers show no histomorphological abnormality. (e) Hematoxylin and eosin staining of the heart of rat of AE group (hematoxylin-eosin, original magnification ×100). Hollow arrow indicates the splitting of myocardial fibers, and solid arrow indicates minimal vacuolar degeneration. (f) Hematoxylin and eosin staining of the heart of rat of NAOEAE group (hematoxylin-eosin, original magnification ×100). Arrows indicate minimum separation of fibers. (g) Hematoxylin and eosin staining of the heart of rat with standard (gemfibrozil) group (hematoxylin-eosin, original magnification ×100). Arrows indicate minimal separation of fibers.
