[Cerebrospinal fluid protein electrophoresis in non-inflammatory central nervous system diseases].

Cerebrospinal fluids (CSF) (N = 365) from patients with non-inflammatory diseases of the central nervous system were analyzed for protein distribution by agar gel microelectrophoresis. After subdivision into diagnostically well defined groups, these patients were compared with 79 normal controls. Most of the diseases investigated were found to follow the "plasma-type" pattern. In some of them the deviations from normal were so extensive that a CSF-protein pattern similar to the "acute-phase reaction" in the serum occurred. Moreover, the following characteristics were found: a considerable increase in total protein and the gamma-globulin fractions in neurinomas; a reproducible increase in the alpha1-globulins in metastases of the central nervous system; and a statistically significant difference of CSF protein findings between male and female patients with protrusion of lumbar intervertebral discs.

[Behavior of cerebrospinal fluid proteins in degenerative diseases].

132 cerebrospinals fluids from patients with degenerative diseases of the central nervous system have been analyzed for protein distribution in agar gel electrophoresis. After subdivision into diagnostically well defined groups these patients were compared with 48 with metabolic and psychiatric diseases and with 79 normal controls. The majority of diagnostic groups showed a tendency to permeability impairment. Other outstanding deviations were not found, except for single cases which were not statistically typical of the groups as a whole. However, the "degenerative type" of proteinogram emphasized in the literature predominated not only in the degenerative groups but also in certain other diseases with destruction of central nervous tissue which do not belong to the degenerative diseases in the strict sense. On the other hand, there are some degenerative subgroups without this "typical" electrophoretic pattern. There would thus appear to be grounds for amending the term "degenerative" into "tissue destroying" or "atrophic type", to avoid misinterpretation.

Absolute or relative values in csf electrophoresis? An evaluation of the gamma-globulins in multiple sclerosis and other neurological diseases.

The frequencies of pathological results in 143 CSF samples of MS patients from the years 1964-1967, and 206 samples from 1968-1973 were compared after agar electrophoresis and cytological differentiation. As they were in good agreement, the two series were combined into one group of 349 MS patients for further comparison with three groups with other neurological diseases (inflammatory, neoplastic and vascular brain affections). Although the absolute gamma-globulin values (mg/l) are somewhat more frequently pathological than the relative values (rel%), they also correlate significantly with total protein and, therefore, do not offer a criterion with a diagnostic value of its own. From them - as from the total protein - a pathological CSF state cna be concluded, but no discrimination between MS and other diseases of the central nervous system is possible. The relative percent values for the gamma-globulins are much less correlated with total protein in all the 4 groups compared; consequently, they represent a more specific criterion for differential diagnosis.
