Nine lysosomal enzymes and alkaline phosphatase have been assayed in human pancreatic juice from controls and patients with chronic calcifying pancreatitis. Specific activities were evaluated by a nonparametric test (Wilcoxon) with a probability of 2 P less than or equal to 0.5. The values of acid phosphatase, alpha-glucosidase, beta-glucosidase and alpha-galactosidase are significantly higher in pathological juices; the values of alpha-mannosidase and beta-glucuronidase are also increased in the same patients but at the limit of significance. Alkaline phosphatase, beta-hexosaminidase and alpha-fucosidase follows the same trend but the values are not statistically significant between the two groups of patients. Studies on skin cultures of four patients with chronic calcifying pancreatitis demonstrate that the increased specific activities of lysosomal enzymes in the pathological juices do not correspond to a leakage of these enzymes into the extracellular space as described for cystic fibrosis.

beta-Galactosidase and associated activities (beta-glucosidase and beta-fucosidase) have been studied in rabbit and bovine liver and rabbit spleen. The physico-chemical (optimal pH, pI, MW) and kinetical (Km, Vmax, Ki) properties were determined for all the activities. Two enzyme forms were separated in rabbit spleen. beta-Galactosidase, beta-fucosidase and beta-glucosidase activities were catalyzed by the same enzyme in rabbit and bovine liver. The enzyme from bovine liver showed nonlinear double-reciprocal plots, suggesting a substrate-activation model, and the presence of more than one binding site in the enzyme. The enzyme activities of several glycosidases were determined in human sera fom control groups and from patients with diabetes mellitus, pancreatitis, hepatitis, cirrhosis, stomach and breast cancer, myocardial infarction and renal failure. The results show significantly different enzyme levels for several glycosidases in all the studied diseases. Experimentally-induced diabetes mellitus, alcoholism and nephrotoxicity in rats showed different glycosidase levels in several tissues, as compared with control groups.
