The activity of several acid hydrolases in different sections of the C.N.S. of various mammalian has been evaluated. The enzymes which have been studied are: beta-glucosidase, beta-galactosidase, beta-N-acetylglucosaminidase, beta-N-acetylgalactosaminidase, beta-glucuronidase, alpha-mannosidase. The enzymes show a higher activity in the gray matter than in the white matter. The results are interpreted on the assumption that glyco-lipoprotein turnover is higher in the gray matter than in the white matter, since myelin, which is the major component of the white matter, is a relatively stable structures.
The lipid and protein composition and the metabolic turnover of myelin in the C.N.S., are briefly reported. For a better understanding, it seemed useful to introduce some historical data on the discovery of myelin and to give a morphological description at structural and ultrastructural level.
