We report the polarographic analysis of subsarcolemmal and intermyofibrillar mitochondria from rat skeletal and cardiac muscle, in order to detect possible biochemical and functional differences. Electron microscopic observation of isolated mitochondria showed normal aspect, with intact membranes. Respiratory control rate with different substrates and state 3 activity did not show differences between subsarcolemmal and intermyofibrillar mitochondria in skeletal muscle and heart.
我们报告了对大鼠骨骼肌和心肌肌膜下及肌原纤维间线粒体的极谱分析，以检测可能存在的生化和功能差异。对分离出的线粒体进行电子显微镜观察显示其外观正常，膜完整。在骨骼肌和心脏中，肌膜下和肌原纤维间线粒体在不同底物下的呼吸控制率及状态3活性均未显示出差异。
