[Cerebrospinal fluid prealbumins in children with subacute sclerosing panencephalitis].

In the cerebrospinal fluid of 26 children with SSPE the levels of prealbumins and total proteins were determined and electrophoretic separation of proteins was done. The usefulness is discussed of the percent proportion of prealbumins in the cerebrospinal fluid as a criterion indicating damage to the blood-cerebrospinal fluid barrier with increased penetration of proteins in SSPE. It is concluded that in diseases in which biosynthesis occurs of proteins in the central nervous system the percent proportion of prealbumins fails to reflect the integrity of the brain-cerebrospinal fluid barrier.
