  • Title: Experimental immune complex glomerulonephritis in dogs receiving cationized bovine serum albumin.
    Author: Wright NG, Mohammed NA, Eckersall PD, Nash AS.
    Journal: Res Vet Sci; 1985 May; 38(3):322-8. PubMed ID: 3892609.
    Abstract:
    Eight 16-week-old dogs were used to induce immune complex glomerulonephritis by daily intravenous injections of 120 mg highly cationized bovine serum albumin (pI9.5). Of four control dogs, two received unmodified native anionic bovine serum albumin (pI 4.5) while the other two received only phosphate buffered saline. The renal glomeruli were examined by light, electron (transmission and scanning) and immunofluorescence microscopy at intervals from five to 11 weeks after the start of the injections. Animals receiving cationic antigen all developed generalised diffuse granular deposits of IgG and C3 along the capillary walls; these were detected as early as five weeks and continued until the termination of the experiment at 11 weeks. Ultrastructural studies revealed many electron dense deposits along the subepithelial regions of the glomerular basement membrane. The experimental disease resembled in many respects naturally occurring membranous nephropathy, the most common form of immune complex glomerulonephritis in dogs.
