实验性心肌缺血的生化变化可能与冠心病及心衰有关。本文研究由“慢性”缺血的心肌所提取的肌浆球蛋白B(Myosin B 即 Natural actomyosin自然肌纤凝蛋白)与调节蛋白(即向宁蛋白与向肌凝蛋白系统)性能的改变。 方法:结扎狗心脏之左侧环行动脉,造成心肌缺血,1～112天后摘出心脏,取邻近紫 Biochemical changes of experimental myocardial ischemia may be related to coronary heart disease and heart failure. This article investigates changes in the properties of Myosin B, a natural actomyosin protein, and regulatory proteins (ie, ningtins and myosin systems) extracted from “chronic” ischemic myocardium. Methods: Ligation of the left side of the dog’s circulatory artery, causing myocardial ischemia, 1 to 112 days after the removal of the heart, take the near purple
