Serum elastase and its inhibitors in the blood of heavily burnt patients.

Abstract
Serum elastase and its inhibitors were determined in the sera of extensively burnt patients. Serum elastase levels were elevated at 2-8 days after a severe burn accident and returned towards normal values from the 10th day on. Both .alpha.1-antitrypsin and .alpha.2-macroglobulin levels were also elevated in the sera of heavily burnt patients. .alpha.1-Antitrypsin showed a parallel evolution to the elastase level but .alpha.2-macroglobulin followed a somewhat different time curve. Plasminogen and antithrombin were not significantly elevated. Serum elastase may play a role in tissue degradation in burnt patients.
