Histochemical investigation of nonspecific acid phosphatase in cerebral tumors

Abstract

✓ The activity of acid phosphatase in 144 cerebral tumor biopsies was investigated in an attempt to reveal correlations between enzymatic activity and biological states of the tumor cells. The distribution and intensity of the product of enzymatic reaction in different types of tumors, especially in some rare neoplasms (medulloepithelioma, gangliocytoma), showed evidence of the link between vascularization and the activity of the enzyme.
