  • Title: Determination of the minimal amount of IgG synthesized within the central nervous system in different neurological diseases.
    Author: Kerényi L, Koltai M, Pálffy G.
    Journal: Acta Med Acad Sci Hung; 1979; 36(4):367-73. PubMed ID: 122042.
    Abstract:
    The albumin and the IgG were determined in cerebrospinal fluid (CSF) and serum samples from 312 patients by radial immunodiffusion. The correlation between the CSF/serum ratio of IgG and the CSF/serum ratio of albumin was determined by regression analysis in three groups of patients with no signs of IgG synthesis within the central nervous system. The patients were selected on the basis of the state of the blood-CSF barrier, as indicated by the ratio of serum/CSF of albumin. Using the +2 S.D. regression borderlines, the maximal amount of IgG derived from the blood and the minimal amount of IgG synthesized within the central nervous system can be calculated in CSF samples of patients with acute infections and chronic inflammatory diseases.
