2', 3'-cyclic nucleotide 3'-phosphohydrolase activity in postmortem human spinal fluids. 1980

K Fan

The activity of the myelination-related enzyme, 2', 3'-cyclic nucleotide 3'-phosphohydrolase (CNP), was determined in neurologically normal living and postmortem human spinal fluids, for the purpose of examining the differences in enzymatic activity level and stability. A significant elevation of the enzymatic activity was found in the postmortem samples, and the activity in spinal fluid was labile with respect to postmortem time and sample storage conditions. Findings suggest that caution should be exercised in the interpretation of CNP activity in spinal fluid samples.

UI	MeSH Term	Description	Entries
D009103	Multiple Sclerosis	An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur.
