Experimental studies on factors causing acute serum sickness glomerulonephritis of immune complex origin. II. Pathomorphological analysis.
Seventeen rabbits were given a single, large dose of bovine serum albumin (BSA) intravenously. Percutaneous kidney biopsy was carried out on the 14th and 31st days after BSA administration. Proteinuria was measured and the glomerular changes were analysed in order to find a correlation between the degree of proteinuria and glomerular alterations, i.e. number of electron-dense deposits (EDD), polymorphonuclear leukocytes (PMNL), and mononuclear marcophages (MNM). The results speak in favour of the decisive role of mononuclear macrophages in enhancement of glomerular permeability.
