Twelve acid hydrolases, 4 near-neutral hydrolases, and alkaline phosphatase were demonstrated in 0.34 M sucrose homogenates of Trypanosoma cruzi strain Y: p-nitrophenylphosphatase and alpha-naphthylphosphatase, with optimum pH at approximately 6.0; alpha=ga;actpsodase. beta=ga;actpsodase. beta=g;icpsodase, N-acetyl-beta-glucosaminidase, cathepsin A and peptidase I and III, with optimum pH between 5.0 and 6.0; and arylsulfatase, cathepsin D, alpha-arabinase and alpha-mannosidase with optimum pH at approximately 4.0. alpha-Glucosidase, glucose-6-phosphatase and peptidase II had optimum pH at approximately 7.0. beta-Glycerophosphatase had a broad pH-activity curve from 4,0 to 7.4, with maximum activity at pH 7.0. The main kinetic characteristics of these enzymes and their quantitative assay methods were studied. No activity was detected for alpha-fucosidase, beta-xylosidase, beta-glucuronidase, elaidate esterase, acid lipase, and alkaline phosphodiesterase.

Acute and chronic liver damage was caused by the administration of either galactosamine or carbon tetrachloride. Consequently, the rats with damaged livers were killed after vitamin E was administered. The livers were removed and were homogenated. Indicator enzymes (5'-nucleotidase, arylsulfatase, cytochrome C oxidase and glucose-6-phosphatase) of organella membranes were measured in the homogenates of the normal and damaged livers. The effects of vitamin E resulted in the stabilizing of the impaired membranes of plasma, lysosome, mitochondria and microsome; (1) the abnormal decrease of 5'-nucleotidase activity and glucose-6-phosphatase activity, and the abnormal increase of arylsulfatase activity, which induced galactosamine or carbon tetrachloride, and (2) the abnormal decrease of cytochrome C oxidase activity induced by galactosamine- HCl, were normalized.
