本文第一部分初步总结了人心肌细胞损害时乳酸脱氢酶(LDH)同功酶的变化,并提出了测定LDH同功酶作为克山病及其他心肌疾患早期诊断指标的可能性。 为了进一步从理论上阐明心肌细胞损害的规律和LDH同功酶对于心肌细胞损害的指标作用,我们曾先后应用异丙基肾上腺素、一氧化碳、亚硝酸盐等多种实验条件诱发大白鼠的实验性心肌损害。对于这些实验性动物模型,应用LDH同功酶检查和病理形态学检查手段,动态地研究了心肌细胞损害发生发展的规律性。其结果确证了,(1)SLDH同功酶谱
The first part of this article summarizes the changes of lactate dehydrogenase (LDH) isozymes in human cardiomyocyte damage and proposes the possibility of determining LDH isoenzyme as an early diagnostic indicator of Keshan disease and other myocardial diseases. In order to further elucidate the law of cardiomyocyte damage and the index of LDH isoenzyme on cardiomyocyte damage in theory, we have used experimental conditions such as isoproterenol, carbon monoxide and nitrite to induce the experiment of rats Myocardial damage. For these experimental animal models, LDH isozymes and histopathological examination were used to dynamically study the regularity of cardiomyocyte damage. The results confirm, (1) SLDH isoenzyme
