Abstract

The purpose of the present study was to define the normal range of plasma concentration of angiotensin I-converting enzyme(ACE), N-acetyl-b-D-glucosaminidase(NAG), inactive and active renin, and atrial natriuretic peptide(ANP) in normal Korean adult male in terms of aging. Both plasma ACE activity and NAG concentration were measured by spectrofluorometry, and the plasma renin activity and ANP concentration were measured using radioimmunoassay. The ACE was 67.7+-3.6 nM His-Leu/min/ml and did not change in terms of age. The plasma NAG activity tended to decrease. Both plasma active and inactive renin activities were 2.1+-0.2 and 3.0+-0.3 ngAI/ml/h and tended to decrease in terms of aging. The percentage of inactive renin to total renin was 57.2+-2.9% at age 21-30 and also tended to decrease in terms of aging. Plasma ANP concentration at age 22 was 59.6+-2.9 pg/ml.
