Electron microscope of ablated tissue. A. Electron microscope of the first group (×8000), aligned myofibrils were full of the cytoplasm, the structure of a sarcomere kept integral; B. Electron microscope of the first group (×20000), abundant mitochondria located between nuclei and myofibrils, and contained intensive cristae full of inner mitochondrial space; C. Electron microscope of the second group (×8000), the myofibriles and mitochondria got swollen; D. Electron microscope of the second group (×20000), mitochondria got irregular and the inner cristae became sparse.
