Abstract

Electron microscopic X-ray microanalysis and atomic absorption spectrophotometry were used to determine changes in zinc concentration after myocardial ischemic injury by coronary ligature in dogs. The zinc concentration increased in the damaged myocardium especially in specific intracellular locations identified by means of the microprobe. It was concluded that the selective zinc augmentation was related to proliferative and biosynthetic reactive processes in the myocardium.

摘要

采用电子显微镜X射线微量分析和原子吸收分光光度法，测定犬冠状动脉结扎致心肌缺血损伤后锌浓度的变化。受损心肌中的锌浓度升高，尤其是在通过微探针确定的特定细胞内位置。得出的结论是，锌的选择性增加与心肌中的增殖和生物合成反应过程有关。
