    Notes: Abstract The binding of human platelet cationic proteins (HuPlt CP) to rat renal cortexin vitro andin vivo, the loss of glomerular polyanions (GPA) and the increase in glomerular permeability were studied. HuPlt CP were purified by sequential cation-exchange chromatography and chromatofocusing, by which these proteins were shown to be highly cationic in nature (pI 10.5) and mainly composed of three molecular species of 55.60 kD, 40.45 kD, and 10 kD as studied by gel permeation in high pressure liquid chromatography and SDS-polyacrylamide gel electrophoresis. Binding of HuPlt CP to glomerular capillary walls (GCW), mesangium and to peritubular capillaries of the rat renal cortex was demonstrated by immunofluorescence, using a specific goat anti-HuPlt CP antiserum, after incubation of the sections with HuPlt CPin vitro and after injection of HuPlt CPin vivo. This interaction was ionic in nature, since treatment of sections with heparin abrogated the binding of HuPlt CP to glomerular structures. The glomerular deposits of HuPlt CP were associated with the loss of GPA as revealed by colloidal iron staining (light microscopy) in bothin vitro andin vivo experiments and by ruthenium red staining (electron microscopy) inin vivo studies. After the injection of native ferritin, the increase in glomerular permeability produced by an infusion of HuPlt CP was observed by the increased ratio of counted particles within the glomerular basement membrane with respect to controls. The binding of HuPlt CP to GCW and the loss of GPA was consistent with the interpretation that HuPlt CP may increase glomerular permeability due to the neutralization of GPA.

    Description / Table of Contents: Summary Clinicopathological ultrastructural, and immunohistochemical findings of a new case of IgG1 heavy chain disease are reported in detail. The abnormal protein lacks the VH and CH1 region with sequence starting at 225 residue. The main pathologic feature was a plasmacytic tumor of the lymph nodes with B-cell immunoblastic sarcoma patterns. Neoplastic diffusion to other organswas also present. Plasmacytic neoplastic cells have also been found in the bone marrow. The ultrastructure of the neoplastic cells was characterized by more or less abundant plasmacytic-like endoplasmic reticulum with very frequent peculiar whorled configurations. Immunohistochemical methods revealed the abnormal protein production by neoplastic cells in different stages of differentiation. From this case and from the data of the literature it is concluded that the γHCD is due to a neoplastic proliferation of lymphoplasmacytic cells whereas the reticulum cells are never involved.
    Notes: Zusammenfassung Klinishi-pathologische, ultrastrukturelle und immunhistochemische Befunde von einem Fall der IgG1 Schwerkettenkrankheit werden detailliert beschrieben. Dem Protein fehlt die VH und CH1 Region; die Sequenz beginnt mit dem 225 Rest. Pathologisch-anatomisch befand sich vor allem eine plasmazytische B-Zellgeschwulst der Lympknoten vom Typus eines immunblastischen Sarkoms. Es bestanden neoplastische Infiltrate auch in anderen Organen, darunter dem Knochenmark. Die Ultrastruktur der Geschwulstzellen war durch mehr oder weniger reiches plasmazellähnliches endoplasmatisches Retikulum charakterisiert, häufig mit eigentümlichen konzentrischen Formationen. Die immunhistochemische Untersuchung erwies die Produktion eines abnormalen Proteins in den neoplastischen Zellen verschiedentlichen Differenzierungsgrades. Von diesem sowie von den anderen Fällen der Literatur ergibt sich, daß die γ HCD von der Proliferation und von Tumoren des lympho-plasmazytären Zellsystems verursacht wird, während die Retikulumzellen dabei keine Bedeutung besitzen.
