[The effect of desoxycorticosterone acetate on the activity of the lysosomal enzymes of lymphoid organs].
The authors present the results of study or fegularities attending the changes in the activity of free, total and bound fractions of the lysosomal enzymes--beta-glucosidase and beta-galactosidase in the thymus and the spleen of rabbits under conditions of DOCA administration.  The activity of the enzymes was studied 30 min, 1, 4, 12, 24 and 48 hours after a single injection of the hormone.  DOCA administration caused biphasic changes in the activity of both glycosidases.  A marked increase in the activity of all the enzyme fractions during the first experimental hours was later replaced by their fall.  An increase in the activity of glycosidases at the early periods of DOCA administration pointed to the intensification of the enzymatic synthesis, and also could be associated with the spicific induction of the enzymatic activity.  The activity of beta-glucosidase and of beta-galactosidase directly depended on DOCA dose.  Effects similar to the experiments in vivo were obtained in vitro.  The activity of hyaluronidase under the effect of Dca decreased considerably in the thymus and the spleen, particularly at the early experimental periods, pointing to reduction of tissue permeability of the lymphoid organs.
