[Venography with 111Indium-labelled autologous thrombocytes].

111Indium-labelled thrombocytes were used for radionuclide venography in ten patients. All types of thrombi could be demonstrated with a high degree of accuracy, particularly if the marked thrombocytes were injected distally. In cases of complete occlusion by thrombus, the peripheral end of the clot appeared as a 'hot spot'. Non-occluding thrombi with a thrombogenic surface can be differentiated from lesions of the endothelium. Compared with venography using labelled microspheres, labelled thrombocytes have the advantage of demonstrating the degree of activity of the thrombotic process.

[Blood loss in dialysis in repeatedly used capillary dialysators].

The blood losses increase to the twofold to threefold by capillary dialysators C-DAK 4 and C-DAK 5 are about 6.8 ml and 26 ml, respectively, in the first use. In repeated use of the C-DAK 4 the blood losses by the C-DAK 5, however, are so high that it is not to be advised to use them manifold under our conditions of dialysis. By an increase of the reperfusion quantity from 150 to 250 ml of electrolyte solution for one C-DAK 4 blood losses may considerably be reduced. In a parallel switching of two C-DAK 4 each exemplar should be perfused individually.

[A modified method for labeling erythrocytes with 99mTc (author's transl)].

A modified method for labeling erythrocytes with 99mTc-sodium pertechnetate for spleenic scintigraphy is described. In vitro investigations have shown that by omitting the customary process of washing and by simultaneous alteration of the erythrocytes during the tin incubation period, the duration of erythrocyte labeling can be considerably reduced. A yield of 96 of 98% can be achieved. The effect of the tin on the erythrocytes is further investigated. The effect of the incubation period and temperature, of the plasma in the erythrocyte suspension, of stirring and agitation, of the dispersion liquid and tin concentration were studied. The method proves satisfactory in 56 controlled spleenic scintigrams.
