ABSTRACT
Plasminogen activators were studied in blood urine in 207 patients with nephrotic syndrome of different etiological forms. The blood plasminogen activator activity was decreased in chronic glomerulonephritis, SLE, systemic vasculities as result of great level of inhibitors (L2M), penetration of enzymes to abdominal and pleural transudates, excretion to urine. The blood plasminogen activator activity and urokinase level in chronic glomerulonephritis was dependent on the degree of nephrotic syndrome. The plasminogen activator in amyloidosis was sharply elevated because of permanent irritability of endothelial wall by amyloid mass. Venous occlusion caused the release of plasminogen activator to blood only in more favourable clinical course of nephrotic syndrome.
