[Separate flows of erythrocytes with different degrees of oxygenation in the venous vessels]

Having studied the structure of the blood flow in pial microvessels of the rat brain, the blood flow in venules was shown to consist of separate erythrocyte flows divided by the plasma layers Visualisation of these flows is facilitated after isovolume hemodilution until the 20-25% hematocrit. The blood flows in the same microvessel were found to differ from each other essentially by the oxygen tension level and by the velocity of their transition.
