[Active dehydration of brain tissue as a compensatory phenomenon in the development of edema].
In experiments on adult rabbits edema of the brain developed regularly as the result of repeated regulated increase of general venous pressure which led to venous blood stasis in the brain. In determining the dependence of simultaneously recorded changes in the brain volume on its blood filling during tests with venous pressure increase, it was found that during the development of brain edema a tendency to accumulate water in the brain tissue occurred in some periods and a tendency to dehydration of the brain in others. Thus, besides the earlier detected compensation for the development of brain edema by means of circulatory changes, proof has been obtained that this compensation may occur due to active transport of water from the tissue to the blood stream.
