Pathological changes in myocardial cell mitochondria and myoneme under electron microscope. Ultrastructural examination was performed as described in materials and methods. a In CIH group, the number of mitochondria decreased, the size was unequal and abnormal, the mitochondrial membrane was incomplete, and the electron density of matrix increased. b In ARB group, the electron density of the mitochondrial matrix increased the same as CIH group while the quantity and size of the mitochondria were normal and the membrane was intact. c & d. In blank and air control groups, the electron density of the mitochondrial matrix was nomal, the quantity and size of the mitochondria were normal and the membrane was intact. The coarse and fine filaments were well arranged and each band was clearly visible in four experimental groups (a-d). Magnification: 40000×, scale bar, 1 μm
