Abstract
Activity of the myelin marker enzyme 2′,3′‐cyclic nucleotide 3′‐phosphohydrolase (CNP) was assayed in cerebrospinal fluid samples obtained from patients with multiple sclerosis (MS) and other neurological diseases. The enzyme activity was found to be elevated in acute cases of MS and reduced during remission. It was present in other demyelinating diseases, and no activity was detected in normal CSF. CNP may be released into CSF from any insult to myelin. The level of activity appears to reflect demyelination and the rate of breakdown of the myelin sheath.Keywords
