[Carboxypeptidase N and angiotensin converting enzyme activity in rat blood serum in health and during emotional stress].

The effect of emotional stress on both carboxypeptidase N and angiotensin converting enzyme activities in the blood serum of stable and predisposed rat was studied. It was found that activities of both enzymes in serum of stable rat was higher as compared with those predisposed to emotional stress. During emotional stress a decrease of both enzymes activities was observed. Both enzymes activities in rats with different degrees of tolerance to emotional stress were changed differently.
