[The value of venous capacity measurements in the diagnosis of venous function].

Phlebography, has been compared with the results of venous capacity measurement taken from 150 patients, 76 women and 74 men. The measurement of the venous capacity is a appropriate screening method to determine any irregularities of the deep venous hemodynamic. It is possible to attain a more exact indication for the phlebography. Maximum expression of the values of venous capacity, is however, contained in the functional periodical controls of the pathologic processes of the deep venous system.

[The effect of tissue resistance on rheography].

Herewith a formula for the computation of the relative stroke volume in limbs is derived, taking into account the differences between the electrical resistivity of blood and tissues, respectively. In order to properly estimate the influence of this difference in resistivity, the appropriate variables were measured in 20 different persons. Results from these tests indicated that the value for tissue resistivity, on the average, was about 30% above that of the resistivity of blood. Consequently, computations of the stroke volume in limbs that neglect this essential difference in resistivity, contain a systematical error in measurement, amounting to 30%. It is the purpose of this paper to portray a method of considerably reducing this error, without the necessity--in each specific case--to measure blood resistivity.

[Demonstration of arterial vascular occlusions using 125 I-fibrinogen].

In 10 patients with arterial occlusions, 125-I fibrinogen was injected intravenously. In all patients with acute embolic or thrombotic arterial occlusions verified surgically and/or angiographically, a significant accumulation of radioactivity in the affected region was observed. The use of 125-I fibrinogen in this manner obviously is a valuable means for the detection and localization of acute arterial occlusions.
