[The antiprotease alpha-1-antitrypsin, alpha-2-macroglobulin and immunoglobulin E in newborns with hyaline membrane (author's transl)].

The Authors have analyzed the serum from 26 newborn children suffering from hyaline membrane to valuate the behaviour of alpha-1-antitrypsin, of alpha-2-macroglobulin, and of immunoglobulin E. A statistically significant decrease of antiprotease seric levels has been noticed. No information has been achieved as concern IgE.
