[The effect of emotional-pain stress on the activity of carboxypeptidase N--the enzyme of neuropeptide processing in the rat brain].

Activity of carboxypeptidase N [correction of H] increased under emotional-algic stress in the rat pituitary gland and hypothalamus. Carboxypeptidase N [correction of H] seems to be involved in development of the stress response, and soluble forms of the enzyme take part in processing of secretory peptides. Membrane-bound forms take part in processing of the neuropeptides specific by their central action.
