[Use of the polarographic method of analyzing blood and cerebrospinal fluid for diagnosing nervous system diseases].

The report contains the results of a palrographic study of the blood and CSFin 726 patients with different disorders of the nervous system. It was possible to demonstrate statistically significant differences in the degree of expressiveness of the Brdicki filtrate test in benign and malignant tumors. The authors also established the significance of a differential diagnostical test, permitting to distinguish a vascular (pseudotumor) brain disorder from a tumorousone. A polarographic analysis of the CSF may be used as a supplementary diagnostical method in tumors of the CNS. The role of sulfhydrile groups in the mechanism of the polarographic effect is discussed.
