[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.

Pre-mortem diagnosis of Creutzfeldt-Jakob disease by detection of abnormal cerebrospinal fluid proteins.

Creutzfeldt-Jakob disease (CJD) may be difficult to diagnose early or when it has an atypical presentation. We describe two patients with progressive dementia in whom the results of diagnostic brain biopsies were unhelpful. Spinal fluid from these patients, analyzed by two-dimensional electrophoresis, contained two abnormal proteins (Nos. 130 and 131, with relative molecular masses of 26,000 and 29,000 daltons and isoelectric points of 5.2 and 5.1). These findings suggested a provisional diagnosis of Creutzfeldt-Jakob disease, which was confirmed in both patients at autopsy. Detection of these abnormal cerebrospinal fluid proteins appears to be a valuable laboratory adjunct in evaluating patients with an unexplained progressive dementia.

Increased cerebrospinal fluid protein tau concentration in neuro-AIDS.

OBJECTIVES: Assessment of cerebrospinal fluid (CSF) levels of protein tau in human immunodeficiency virus type 1 (HIV-1) infection. MATERIAL AND METHODS: CSF tau levels were analyzed in 52 HIV-1-infected patients, 37 of whom had no neurological symptoms, eight had aquired immunodeficiency syndrome (AIDS) dementia complex (ADC), and seven had AIDS with other neurological complications. RESULTS: A significantly higher mean CSF tau concentration was found in patients with ADC (380 pg/ml) compared with patients with neuroasymptomatic HIV-1 infection (120 pg/ml, P<0.01) and HIV-negative controls (150 pg/ml, P<0.05). No difference in CSF tau levels was found between patients with ADC and patients with AIDS with other neurological complications. CONCLUSION: CSF tau might be used as a biochemical marker for axonal degeneration and might be of use to identify HIV-1-infected patients with ADC and other neurological complications, but it cannot discriminate between ADC and other neurological complications in HIV-1-infection.

[Cerebrospinal fluid proteins in the course of subacute sclerosing panencephalitis in children].

In cerebrospinal fluid samples obtained from lumbar tap from 31 children with subacute sclerosing panencephalitis the concentration of total protein was determined and electrophoretic separation of protein fractions on paper was carried out from 1 to 28 months after the onset of first clinical symptoms. Moreover, in 22 children the concentration of IgG was determined by electroimmunodiffusion. The reference group included 22 children without organic diseases of the central nervous system. In nearly half the samples of the cerebrospinal fluid obtained from these children a rise was observed in total protein level, and in most samples a significant fall of albumin proportion and an evident rise of this relative proportion of globulins (tau + gamma) and IgG immunoglobulins was observed. No correlation was demonstrated between changes in cerebrospinal proteins and the phase of the disease and its duration.

[Determination of proteins with the Coomassie brilliant blue G 250 method. IV. Use with cerebrospinal fluid proteins and comparative analysis with the biuret and Lowry methods].

The method of Bradford with Coomassie Brillant Blue G 250 for protein assay has been applyed to CSF in comparison with biuret and Lowry's methods. The results of Coomassie method closely agree with Lowry, and are similar to those of biuret. It is suggested to replace the previously used methods for CSF protein assay by the Bradford's method, because it keeps the sensitivity of Lowry and the simplicity of biuret. It adds too the advantage of requiring less time.
