Abstract
The activities of acid phosphatase and N-acetyl-.beta.-glucosaminidase were measured in 171 CSF samples from 104 patients suffering from multiple sclerosis. The mean level of activity of these enzymes was lower than that of controls. Patients who had the 1st or 2nd bouts had somewhat higher activity of these enzymes compared to controls. The lowest values of these enzymes were found in patients with severe disability. Patients with late onset of the disease had higher levels of the enzymes compared to patients with an earlier debut of the illness, whereas patients with a short history had higher values than patients with a longer duration.
