[Studies on the function of blood-liquor barrier in newborn infants].
Simultaneous measurement of the electrolytic conductivity of the cerebrospinal fluid and the blood serum in newborns has revealed a concentration gradient suggesting an active transfer of electrolytes into the liquor space. The extent of this concentration drop is regarded as expressing the functional capacity of the blood-liquor barrier. Comparative investigations in healthy older  children shown that constant values, corresponding to the adult age, are reached approximately at the end of the first year of life.
