Histochemical, biochemical, microfluorometric and electron microscopic studies were made of the spleen of a patient with type I hyperlipoproteinemia. Foam cells were observed that contained a material identified as ceroid on the basis of its autofluorescence, acid-fastness, sudanophilia, PAS-positivity and insolubility in organic solvents. Electron microscopy showed that the ceroid was organized in the form of granules with concentric lamellae of irregular periodicity. The process of formation of these granules is described in detail. The ceroid was considered to represent nondigestible end products of the metabolism of chylomicrons taken up by macrophages in splenic sinusoids.
对一名患有I型高脂蛋白血症患者的脾脏进行了组织化学、生物化学、显微荧光测定和电子显微镜研究。观察到泡沫细胞含有一种物质,根据其自身荧光、抗酸性、嗜苏丹性、PAS阳性以及在有机溶剂中的不溶性,该物质被鉴定为类蜡质。电子显微镜显示类蜡质呈颗粒状,具有不规则周期性的同心薄片。详细描述了这些颗粒的形成过程。类蜡质被认为代表了脾血窦中巨噬细胞摄取的乳糜微粒代谢的不可消化终产物。
