Changes in serum angiotensin I converting enzyme activity due to carbon disulfide exposure

The activity of serum angiotensin I converting enzyme (ACE) was determined in 50 workers from a viscose factory in Banja Luka, Yugoslavia, and in 50 control subjects. Activity of serum ACE was significantly lower in workers exposed to carbon disulfide than in the control group. No correlation was found between a decrease of serum ACE in exposed workers and duration of exposure. These findings indicate that the serum ACE may be influenced by carbon disulfide, but the mechanism of these changes remains to be elucidated in this case.
