Plasma galactocerebrosides in multiple sclerosis.

Plasma cerebrosides were examined in 12 cases of multiple sclerosis which were compared to normal controls and patients with cerebrovascular accidents. A screening was performed so as to select patients with levels above to normal by means of thin-layer chromatography of the lipid extract. Glucose seems to be the only hexose to be found normally in plasma cerebrosides. The presence of galactocerebrosides may be a biological test for demyelination, as their presence seems to be related to the evolutionary state of multiple sclerosis. In a severe cerebrovascular accident, galactocerebrosides were also found.
