Histopathological changes in miniature pig myocardial tissue (H&E staining).

<p>The myocardial fibers from the control miniature pigs were neatly and tightly arranged (A, E, I, M, C, G, K, and O), but they were disorganized in the HFHSD group miniature pigs (arrows in N and P), showing inflammatory cell invasion (arrows in F and H) and cardiomyocyte hypertrophy (arrows in J, L). The tissue of the HFHSD group miniature pigs exhibited fat deposits (arrows in B and D), and some of the myocardial fibers were deformed by fat. A, E, I, M, C, G, K, and O: control group; and B, F, J, N, D, H, L, and P: high-fat and high-sucrose group; bar = 50 μm.
