Abstract
A comparative investigation was made on muscle tissue of man, dog and rat during ischemia of five hours duration. The content of energy rich phosphates was measured. The ATP level decreased after two hours ischemia to 68% in man, to 45% in the dog, and to 23% in the rat. By five hours it had fallen further to 25% in man, 9% in the dog and only 1% in the rat. It is concluded that human muscle has a higher tolerance to ischemia.
摘要
对人、狗和大鼠持续5小时缺血期间的肌肉组织进行了对比研究。测定了高能磷酸盐的含量。缺血2小时后，人的ATP水平降至68%，狗降至45%，大鼠降至23%。到5小时时，人的ATP水平进一步降至25%，狗降至9%，大鼠仅降至1%。得出的结论是，人类肌肉对缺血具有更高的耐受性。
