Enzymatic determinations of four enzymes, Arylsulphatase A (ARSA), alpha-iduronidase (IDUA), beta-galactosidase (GLB) and hexosaminidase were performed in 19 cases of meningioma. Gene dosage effect was demonstrated for ARSA and IDUA; preliminary evidence for mapping a "protective protein" of GLB in the region 22pter----q11 was also obtained.

Estimation of activity of five hydrolytic enzymes was made in foru histologically different types of human meningiomas derived from surgery. The hydrolytic enzymes examined in 13 tumors included four lysosomal enzymes: beta-glucuronidase, N-acetyl-beta-D-glucosaminidase (hexosaminidase), beta-galactosidase, and acid phosphatase. The fifth enzyme studied was alkaline phosphatase. The one papillary-type meningioma examined appeared to contain generally greater activities of the lysosomal enzymes than the other tumor types. Alkaline phosphatase was decidedly greater in transitional type meningiomas. The correlation of histological types with alkaline phosphatase activity is discussed with regard to previous observations.
