服用或注射含铁量高的物质以及特发性血色病(hemochromatosis)病人体内会发生铁的沉积,关于铁在细胞内沉积的形态表现,过去有过很多报导,但并未能提出直接证据。电子显微镜超微结构的观察结合元素的x射线显微分析是获取有关直接证据的有效方法。本文报告了应用这种方法观察血色病病人肝内铁沉积点的超微结构特征。
Iron deposition occurs in patients taking or injecting iron-rich substances and in patients with idiopathic hemochromatosis. There have been many reports of morphological manifestations of iron deposition in cells, but no direct evidence has been presented. Observation of the electron microscopic ultrastructure X-ray microscopic analysis of the binding elements is an effective method of obtaining direct evidence. This article reports the application of this method to observe the ultrastructural features of intrahepatic iron deposition in patients with hemochromatosis.
