[Immunochemical determination of neurospecific beta 2-globulin in cerebrospinal fluid in mental disorders].

Immunochemical identification of neurospecific beta 2-globulin (N beta G) in the cerebrospinal fluid (CSF) of mentally healthy subjects and mental patients showed its immunochemical identity in both group. A comparative immunochemical analysis revealed considerable differences in N beta G levels in the CSF in patients with neuropsychic diseases as compared with the control group. The content of N beta G was found to vary in different psychopathological syndromes. It is suggested that variations in N beta G levels in the CSF may be related to psychomotor activity.
