Cerebrospinal fluid proteins and cells in men subjected to long-term exposure to organic solvents.
Cerebrospinal fluid (CSF) was obtained from 17 men occupationally exposed to organic solvents and diagnosed as having a psycho-organic syndrome. Healthy volunteers and patients without neurological disorders were used as controls. The albumin ratio was increased in three heavily exposed men, indicating an increased passage of albumin over the blood-brain barrier. A slight monocytoid reaction was present in three of the subjects in the exposed group. Myelin basic protein and enolase activity were within normal limits. Isoelectric focusing of CSF-enriched proteins obtained by absorption chromatography showed alterations in nine out of 17 exposed individuals: The most prominent change was a relative increase of the protein band with Ip 4.7.
