[Isolation of immune complexes from the vascular wall in experimental immunovasculitis]

In experimental immunvasculitis immunocomplexes of the vessel wall have been detected by indirect immunofluorescence method. In the aortic intima linear deposition, in the small arteries and arterioles segmental fluorescence was observed in all layers of the vessel wall. In some regions a marked positive perivascular reaction was also revealed. Immuncomplexes of the vessel wall may play a part in the preservation and prolongation of the alterations of the vessel wall.
