title: [The effect of duration of endemic nephropathy on serum angiotensin converting enzyme activity].
abstract: The effects of duration of disease on serum angiotensin converting enzyme (ACE) was measured in 60 patients with endemic nephropathy (30 men and 30 women) of age between 30 and 60 years. There were formed three groups: patients with endemic nephropathy and duration of disease less than 5 years (n = 23), patients with endemic nephropathy and duration of disease between 5-10 years (n = 17); and patients with endemic nephropathy and duration of disease 10 years and more (n = 20). The serum ACE activity was determined by the spectrophotometric method using Hip-Gly-Gly as a substrate. The activity of enzyme were expressed in units corresponding to 1 nmol of the hippuric acid that was released by the hydrolysis of Hip-Gly-Gly per minute and ml of serum. The results showed that serum ACE activity decreased in group of patients with endemic nephropathy and duration of disease 10 years and more (29.21 +/- 2.25; X +/- SEM) in comparison with group of patients with endemic nephropathy and the duration of disease less than 5 years (35.57 +/- 1.75), which was statistically significant (p < 0.03).
