Cardiac function and myocardial energy metabolism, and adaptive changes of myocardial energy metabolism is the focus of sports scientific research, is in the study of energy metabolism of myocardial cells mitochondria of hot spots and key points. 心脏机能与心肌的能量代谢密切相关,心肌能量代谢适应性变化是运动科学研究的重点,而心肌细胞线粒体又是能量代谢研究中的热点和关键点。
The content of adenosine triphosphate, mitochondria membrane potential and cell activity were determined at different time points after transient anoxia-serum deprivation / reperfusion. 测定短暂缺氧血清剥夺再灌流后不同时间点的三磷酸腺苷含量、线粒体膜电位和细胞活性。
Results In group HP, the percentage of normal mitochondria and glycogen level were not changed significantly after ischemia at all time points except for the time of clamping 60 min, and was higher markedly than those in group C. 结果(1)电镜:HP组除阻断60min外的其他时点心肌的正常线粒体及糖原含量均接近缺血前水平,明显高于C组和NP组;
