[Hydrolytic enzymes of rat tissues with adjuvant arthritis]

Tissues of rats with adjuvant arthritis manifested differences in activity and distribution between free, latent and membrane-bound forms of acid catepsins, alpha-D- and beta-D-galactosidases, alpha-D- and beta-D-glucosidases, beta-D-glucorunidase, hyaluronidase, acid phosphatase, arylsulphatases (A+B). Activation of certain hydrolytic enzymes is observed in tissues of the liver, kidneys, heart and spleen: a rise in total activity (of arylsulphatase in the liver and acid catepsins in the spleen; hyaluronidase in the kidneys, beta-D-glucuronidase in the heart) and a change in the ratio of different forms with a simultaneous increase in the activity of free form (of hyaluronidase in the spleen, acid phosphatase in the heart and liver). Inhibition of alpha-D-glucosidase in the liver and beta-D-glucosidase in the spleen is also detected. A decrease in the activity of beta-D-glucuronidase in the spleen is pronounced in a significant decrease in the activity of each enzyme free form with no changes in the total activity.
