[Electrical resistance of cerebrospinal fluid in inflammatory diseases of central nervous system in children (author's transl)].

The specific electrical resistance of the cerebrospinal fluid was measured by means of conductometry in 14 cases of meningitis purulenta, 17 cases of meningitis serosa, 10 cases of encephalitis and in 32 control subjects. The mean value was found to be significantly increased in meningitis purulenta in comparison to the control group. The differences between the average values of the electrical resistance concerning other groups studied were found to be unsignificant. In some cases the initially increased electrical resistance of cerebrospinal fluid observed in the acute state of the disease reached the normal levels at the time of clinical improvement. The presumable causes of these phenomena are discussed.
