title: [Determination of enzyme activity and beta 2-microglobulin concentration in the urine in chronic diffuse glomerulonephritis and hypertension].
abstract: Activity of alanine aminopeptidase (AAP), aryl sulphatase A (ASA) beta-glucoronidase (beta-GA) and the concentration of beta 2-microglobulin in urine was determined in 12 patients with chronic diffuse glomerulonephritis and in 16 patients with essential hypertension. The control group consisted of 6 practically healthy persons. The AAP activity in urine of patients with chronic glomerulonephritis was significantly higher than that in healthy subjects. Renal excretion of lysosomal enzymes (ASA, beta-GA) appeared to be less expressed; no significant differences as regard to their excretion were noted between the above mentioned groups. Concentrations of beta 2-microglobulin in urine of patients with chronic glomerulonephritis 6 times exceeded its concentration in healthy persons and in hypertensive patients, more than 3 times as much. Determination of the enzyme activity and beta 2-microglobulin concentration in urine may serve a test in differential diagnosis, for evaluation of the treatment efficiency of patients with chronic glomerulonephritis accompanied by arterial hypertension and those suffering from essential hypertension.
