In the normal group, electron microscopy showed normal chondrocytes were oval, and cells and cell membrane were intact. In cytoplasm, there were abundant rough endoplasmic reticulum, dictyosome, and mitochondria with intact nucleus, and even chromatin. In the model group, chondrocytes exhibited obvious pyknosis and their shape was irregular. The areolae around cells disappeared; cell organs in cytoplasm coagulated to flaps which showed electron dense and was uneasy to observe; the shape of nucleus showed irregularity, and caryotin gathered densely.
