[Protective effect of procyanidolic oligomers on the heterologous phase of glomerulonephritis induced by anti-glomerular basement membrane antibodies].

Treatment by procyanidolic oligomers can significantly decrease the proteinuria indiced in the Rat by intravenous injection of anti glomerular basement membranes antibodies. Immunohistological analysis shows that procyanidolic oligomers do not interfere with the mechanisms of immunopathological injury involved in this model (antibody binding to glomerular basement membrane, complement activation, glomerular influx of polymorphonuclear leucocytes). Their protective effect may be due to an increased resistance of the glomerular capillary to the inflammatory mediators released by neutrophils.
