关于移植小球肾病的超微结构研究,在国内未见报告,本文着重对3例尸体肾移植三年后,因移植肾功能衰竭而被切除的肾脏,分别作了光镜、电镜以及免疫萤光的检查,并结合文献对本病与其它型小球肾炎的区别加以讨论。结果与讨论:本文3例均为移植小球肾病,例1比较典型(见图1),虽有报告在1例肺肾综合征患者肾小球基底膜内疏板也有电子透光性物质沉积而增宽,我们认为这种特异性病变仍是与其它类型小球肾炎的主要区别。例2、3为膜增殖性小球肾炎(Ⅰ型)的改变,并有局灶性节段性硬化和新月体形成。电镜下可见系膜细胞 There are no reports about the microstructure of glomerular nephropathy in our country. In this paper, we focus on the three cases of cadaveric kidney transplantation three years after the renal transplantation due to renal failure, made light microscopy, electron microscopy and immunofluorescence Light examination, combined with the literature on the disease and other types of glomerular nephritis to be discussed the difference. RESULTS AND DISCUSSION All three cases were transplanted glomerular nephropathy in this study. Case 1 was typical (Fig. 1). Although there was a report of electron translucent substance deposition in the sparse plate of the glomerular basement membrane in 1 patient with pulmonary syndrome, With widening, we think this specific lesion is still the major difference from other types of glomerulonephritis. Examples 2 and 3 are changes in membrane proliferative glomerulonephritis (type I) with focal segmental sclerosis and crescent formation. Mesangial cells can be seen under electron microscope
