CSF circulation and blood-CSF barrier.

Results of microzone electrophoresis of non-concentrated CSF after staining with nigrosine and after evaluation on non-transparent acetate film are compared with those of isotope cisternography (111In-DTPA). We found that blood-CSF barrier disturbances begin with an increase of the absolute values of prealbumins in normal CSF circulation. When a barrier impairment occurs, by first increasing the absolute values of alpha1-globulins, we state a pathological CSF circulation. In this case, most of the globulin region is pathologic (globulin-type).
