[Electron-microscopy studies of capillaries of the dialyser C-DAK 4 with reference to multiple use]

The results of the examinations show that the integrity of the wall of the capillary is not impaired by the process of purification, but, on the other hand, functional changes by thrombotic occlusion as well as disseminated deposits of protein may be expected. The temporary regime of dialysis mus consider this fact in order to achieve a constant effect. But on principle from the clinical experience and on the basis of these results of examinations a manifold use of the dialysator of the capillary in carrying out the purification measures mentioned may be recommended.
