    Notes: Summary We are reporting about a case of gamma heavy-chain disease (Franklin's disease) with immunovasculitis and rheumatoid arthritis. The diagnosis was confirmed by the results of immunoelectrophoresis of the patient's serum and also by evidence of stimulated lymphocytes without light chain, but having gamma heavy-chain surface proteins. The immunofixation of the serum showed two protein bands of gamma heavy-chains with different loads. These results are confirmed by a two dimensional electrophoresis and isoelectric focussing of the serum proteins. The pathologic protein consists of at least two different heavy-chain proteins (mol wt 40,000 and 80,000) with isoelectric points between pH 5.5 and 7.3. In the urine of the patient pathological gamma heavy chain-protein was found only in a very low concentration. The predominant clinical symptom of the patient was a necrotizing vasculitis which became a therapeutical problem. In the immunofluorescence examination of the skin biopsy specimens, immunoglobulins and C3-complement could be detected in the stratum papillare. This fact would be compatible with the development of antibodies or immune complexes against deposited heavy-chain proteins. The arthropathy and the positive rheumatoid factor could similarly be explained by an immune complex mechanism.

    Description / Table of Contents: Summary A test system for demonstrating complement receptors on human peripheral lymphocytes is described. Red cells coated with antibody and complement formed rosettes around 20% of blood lymphocytes, whereas in controls only very few rosettes were observed. The percentage of lymphocytes with rosettes was related to the amount of complement on the red cells. In contrast to monocytes the complement receptor on lymphocytes was not inhibited by EDTA, whereas trypsin treatment showed an adverse effect on the receptor of both cell types. In 9 of 10 patients with chronic lymphocytic leukaemia a significantly lower percentage of lymphocytes exhibiting receptor activity for complement was observed.
    Notes: Zusammenfassung Ein Testsystem zum Nachweis von Komplementreceptoren an menschlichen Lymphocyten wird beschireben. Bei Zusatz von Erythrocyten-Antikörper-Komplementkomplexen kam es um 20% (10–29%) von Blutlymphocyten zur Rosettenbildung, während in den entsprechenden Kontrollen solche Rosetten höchstens vereinzelt nachweisbar waren. Der Prozentsatz rosettenbildender Lymphocyten war von der Komplementkonzentration abhängig. Im Gegensatz zum Komplementreceptor an Monocyten war der an Lymphocyten durch EDTA nicht hemmbar, während eine Trypsinbehandlung zu einer Hemmung der Reaktion an beiden Zellarten führte. Bei 9 von 10 Patienten mit chronisch lymphatischer Leukämie war der Prozentsatz rosettenbildender Lymphocyten signifikant niedriger als der bei Normalpersonen.
