[Study of electrophoretic mobility of urinary lysozyme in the differential diagnosis of chronic glomerulonephritis and chronic pyelonephritis].

Different electrophoretic mobility of urine lysozyme was established in patients with chronic glomerulonephritis and chronic pyelonephritis during electrophoresis in 12% polyacrylamide gel (gel pH 4.3, electrode buffer pH 4.0). The examination of 128 patients has shown that anode position of lysozyme in electrophoretic tubes is observed in 95% of patients with chronic pyelonephritis, and its anode position in 92% of patients with chronic glomerulonephritis. A method of urine lysozyme electrophoresis under the above conditions was proposed as a noninvasive method of differential diagnosis of chronic glomerulonephritides and chronic pyelonephritides.
