Blood serum angiotensin-converting enzyme, alfa2-macroglobulin and triglycerides in patients with diabetes.

Blood serum activity of ACE, alfa2-macroglobulin as well as triglycerides concentration was determined in 90 patients with diabetes and in 40 healthy persons. Taking into account criteria established by WHO the patients with diabetes were divided into two groups. The first group consisted of 32 patients with diabetes of type I (juvenile one); the second group consisted of 58 patients with diabetes of type II (adult one). It was found that blood serum level of all tested parameters is statistically increased (p < or = 0.001) in comparison with control group. In patients with diabetes of type I the level of alfa2-macroglobulin and ACE was higher than in those with diabetes of type II. The serum contents of triglycerides in both groups of patients was comparable. No correlation between parameters determined in patients with diabetes was found.
