Circulating immune complexes were determined in patients with lung cancer by the C1q deviation test and by column chromatography on Sepharose 6 B. Immune complexes could be demonstrated by the two different methods in 50--80% of patients' sera at the time of diagnosis. Patients with extended disease had more immune complexes than patients with limited(More)
Immune complexes could be isolated from sera of 7 patients with oat-cell carcinoma of the lung, but not from 5 normal controls, using zonal ultracentrifugation. After ultracentrifugation, fractions containing macromolecular IgG were absorbed on a protein A-sepharose column and the immune complexes were eluted and dissociated by glycin-HCl buffer at pH 3.5.(More)
First generation shock wave sources have been proved to disintegrate gallstones effectively, but they require the immersion of the patient's body in a tank of water. A recently developed second generation shock wave source (Siemens-Lithostar, Erlangen, FRG) generates shock waves electromagnetically. It presents several novel features. In particular the(More)
