Distribution of glycanohydrolases activity (hyaluronidase, beta-glucuronidase, N-acetyl-beta-D-hexosaminidase) and glycosaminoglycans in different renal zones (papilla, external medulla, cortex) of homo- and heterozygous Brattleboro rats with hereditary defect of antidiuretic hormone synthesis was studied. Content of the glycosaminoglycans in kidney preparations of homozygotes was shown to be minimal as compared with other rodents; at the same time, the activity of glycanohydrolases in the papilla of diabetic rats was comparatively high. Administration of the antidiuretic hormone at physiological doses was followed by the same increase in the enzymatic activity in renal papilla of homo- and heterozygotes, while certain correlation between the urine osmolality and the degree of the enzymes activation was observed.

Involvement of enzymes catabolizing hyaluronic acid (hyaluronidase, beta-glucuronidase, N-acetyl-beta-D-hexosaminidase) in the hydroosmotic action of vasopressin on the amphibian urinary bladder Rana Ridibunda was studied. It was found that vasopressin (50 nM), agonist of V2 receptors dDAVP (1.5 mcM) and forscolin (30 mcM) induce an activation of enzymes and its release into the Ringer solution at the mucosal surface simultaneously with the increase in the osmotic water flow. Maximal effect was observed 10 min later than hydroosmotic response. Release of enzymes under vasopressin effect was found in the absence of osmotic gradient and water flow through the epithelium. The repeated substitution of the outer Ringer solution for the fresh one resulted in the increase in the both the water permeability and the release of enzymes through the mucosal surface. We suggested that involvement of hyaluronate-hydrolases in the vasopressin effect is mediated by the cAMP-dependent mechanism. It is supposed that this effect creates conditions for the increase in the permeability of glycosaminoglycan structures covering adjacent to the apical cell surface.

The involvement of enzymes catabolizing hyaluronic acid (hyaluronidase, beta-glucuronidase, N-acetyl-beta-D-hexosaminidase) in the hydroosmotic effect of vasopressin in the frog (Rana ridibunda) urinary bladder was studied. It was observed that vasopressin (50 nM), an agonist of V2 receptors, L-desamino-8-D-arginine-vasopressin (dDAVP, 1.5 microM) and forskolin (30 microM) activated the enzymes and caused their release into Ringer solution at the mucosal side, together with an increase in osmotic water flow. The effect of AVP on enzyme activity developed 10 min after the hydroosmotic response. Cytochalasin B (a specific inhibitor of actin filament elongation, 50 nM) blocked the hydroosmotic response to AVP; hyaluronate hydrolase activity increased in the bladder tissue but not in Ringer solution. It is suggested that the involvement of hyaluronate hydrolases in AVP's effect is mediated by a cAMP-dependent mechanism and provides favorable conditions for an increase in the permeability of glycosaminoglycan structures adjacent to the apical cell surface.
