CSF circulation and blood-CSF barrier

H Glasner, U Piepgras

    European Neurology
    |January 1, 1978
    PubMed
    Summary
    This summary is machine-generated.

    Blood-cerebrospinal fluid (CSF) barrier disturbances start with elevated prealbumins during normal CSF circulation. Pathological CSF circulation is indicated by increased alpha1-globulins, suggesting a compromised barrier.

    Area of Science:

    • Neurology
    • Biochemistry
    • Medical Diagnostics

    Background:

    • The blood-cerebrospinal fluid (CSF) barrier is crucial for maintaining central nervous system homeostasis.
    • Understanding early indicators of barrier dysfunction is vital for diagnosing neurological disorders.
    • Current diagnostic methods for CSF circulation may not detect subtle barrier impairments.

    Purpose of the Study:

    • To compare microzone electrophoresis of CSF with isotope cisternography for detecting blood-CSF barrier disturbances.
    • To identify specific protein changes in CSF that correlate with impaired CSF circulation.
    • To establish early biochemical markers for pathological CSF circulation.

    Main Methods:

    • Microzone electrophoresis of non-concentrated cerebrospinal fluid (CSF) using nigrosine staining and acetate film evaluation.

    Related Experiment Videos

  • Comparison of electrophoretic results with isotope cisternography (111In-DTPA) findings.
  • Analysis of absolute prealbumin and alpha1-globulin values in CSF.

    • Main Results:

    • Blood-CSF barrier disturbances are initially indicated by an increase in absolute prealbumin values during normal CSF circulation.
    • Pathological CSF circulation, associated with barrier impairment, is identified by an initial rise in absolute alpha1-globulin values.
    • In cases of pathological circulation, the majority of the globulin region exhibits abnormalities, termed 'globulin-type' pathology.

    Conclusions:

    • Elevated prealbumins in CSF can serve as an early indicator of blood-CSF barrier disturbances.
    • Increased alpha1-globulins signify a compromised blood-CSF barrier and pathological CSF circulation.
    • Microzone electrophoresis offers a valuable method for detecting early-stage CSF circulation abnormalities.
