[Lysozyme concentration in the cerebrospinal fluid of children with epilepsy and subacute sclerosing encephalitis].

Lysozyme concentration in the cerebrospinal fluid was determined in 21 children with epilepsy and 22 children with subacute sclerosing panencephalitis. In most children in both groups the concentration of the enzyme was in the range of control values, but in the remaining children it was above the upper limit of these values. No correlation was demonstrated between lysozyme concentration and total protein level in the cerebrospinal fluid. The causes of raised values of cerebrospinal concentration in these children are discussed.
