  • Title: Daunomycin-induced nephropathy in rats.
    Author: Kubosawa H, Akikusa B, Kondo Y.
    Journal: Acta Pathol Jpn; 1985 Jan; 35(1):109-23. PubMed ID: 2408437.
    Abstract:
    A single intravenous injection of daunomycin into rats induced severe glomerular injury with massive proteinuria. Mesangial thickening due to an increase in the matrix appeared as early as 5 weeks after injection. Focal and segmental glomerular tuft distortion developed by 10 weeks associated with a progressive mesangial change, which was accompanied by detachments of endothelial cells and podocytes from the glomerular basement membrane (GBM) resulting in obliteration of the affected tufts. After 20 weeks, the lesion ultimately progressed to cause diffuse and global glomerular obliteration. Scattered glomeruli also showed frank shrinkage with a mild obliterative change. By observing a number of isolated glomeruli in scanning electron microscopy, it was revealed that podocyte alterations were variable from case to case and foot processes remained discrete in some cases until 10 weeks, despite the presence of marked proteinuria. Anionic sites distributed throughout the GBM and on the surface of podocytes were usually preserved in proteinuric rats as far as evaluated by ruthenium red and colloidal iron stainings. Our results indicate that loss of foot processes and of glomerular anionic sites are not causative factors but consequences of proteinuria.
