The effects of age-specific peculiarities and the duration of maintaining rats on a ration with 4 per cent of protein (the initial mass of rats in the 1st group 100 g each; duration of the experiment--30 days. Initial mass rats in the 2d group--200 g each; duration of experiment--90 days on the activity of the lysosomal hydrolase was studied. The latter included beta-glucosidase, beta-galactosidase, beta-glucoronidase, beta-N-acetylglucosaminidase, arylsulfatase A and B, acid phosphatase, phospholipase A1 and A2, cholinesterase, the total proteolytic activity and that of catepsines A, B, C and D. An ambiguity of changes in the enzymes activity in the animals of the 1st and 2d groups was revealed. Placing the growing animals on a ration containing 4 per cent of protein produces an activation of the most of the lysosomal enzymes, whereas in animals of the 2d test group the nature of changes in the activity of individual enzymes proved to differ quite appreciably. Thus, the summary activity of catepsines, beta-glucoronidase and cholinesterase was below the control level, while the activity of beta-galactosidase, beta-N-acetyl-glucoseaminidase and phospholipase A1 and A2 went up. A prolonged maintenance of rats on a protein-poor ration led to upsetting the stability of the lysosomal membranes, which manifested itself in a higher solubilization of lysosomal enzymes in vitro.
