[Patho-physiological aspects in csf proteins (author's transl)].

Electrophoresis and immunoelectrophoresis of cerebrospinal fluid of 201 patients with inflammatory CNS diseases revealed that over a total protein value from 0 to greater than 1, 2 g/1 there was merely a decrease in pre-albumins and a difference in the gamma-globulins as a pointer to immune reactions. Comparison with the absolute values indicated an increase of all fractions in inflammatory and non inflammatory diseases caused by impairment of the blood-CSF barrier. Again there was evidence of immune reaction in the gamma-globulin range. Impairment in the blood-CSF barrier was demonstrated by an increased concentration of IgG, IgA and IgM. An immune reaction was revealed by higher IgG values.
