the excretion profiles of the following marker proteins of glomerular and tubular origin were studied in patients suffering from chronic renal disease ( gn , n = 36 , gfr : 8 to 120 ml/min/1.73 m2 ) : angiotensinase a ( ata ) , a glomerular endothelial glycoprotein , tubular ala ( -leu-gly ) -amino-peptidase-m ( apm ) , gamma-glutamyl transpeptidase ( ggt ) , and the major brush border surface glycoprotein ( sgp-antigen ) of 240 kd .
