应用电镜及电镜X射线显微分析技术,对一例新生儿溶血症心肌细胞进行了超微结构形态观察并对其线粒体作了元素分析。结果表明,该例心肌细胞病理形态改变明显。线粒体内可见绒球样电子致密体,X射线元素分析证明,该结构中含有大量的氯,而仅含极少量的钙。作者对该异常结构的形成机理及氯沉积的原因进行了讨论。 Electron microscopy and electron microscopy X-ray microscopy analysis of a neonatal hemolytic cardiomyocyte ultrastructure morphology and mitochondria were analyzed. The results showed that the pathological changes of cardiomyocytes obvious. Pomegranate-like electron-dense bodies are visible in the mitochondria, and X-ray elemental analysis has shown that this structure contains a large amount of chlorine but only a very small amount of calcium. The authors discuss the formation mechanism of the anomalous structure and the reasons for the chlorine deposition.
