[Comparative studies of the acid hydrolases of human leucocytes and human and guinea pig alveolar macrophages. I. Study of the activities of glycosidases, arylsulfatase and acid phosphatase (author's transl)]

Abstract

Acid hydrolase activities were compared in human leucocytes, guinea pig and human alveolar macrophages. Several enzymes were characterized: N-acetyl-beta-D-glucosaminidase, N-acetyl-alpha- and beta-D-galactosaminidase, alpha and beta-D-galactosidase, alpha-D-mannosidase, alpha-L-fucosidase, beta-D-glucuronidase, neuraminidase, acid phosphatase and arylsulfatase. The enzymatic activities were lower in leucocytes than in alveolar macrophages, higher in human macrophages than in guinea pig macrophages, except for beta-D-glucuronidase, acid phosphatase and arylsulfatase activities.
