[The trypsin-antitrypsin system and the content of blood middle-molecular peptides in experimental traumatic shock].

: It was established that the activity of trypsin and the content of its inhibitors--alpha 1-inhibitor of proteinases and alpha 2-macroglobulin--undergo phase changes of different meaning and direction with the gradual development of traumatic shock. The character of these changes indicates that trypsinemia is an important pathogenetic link of traumatic shock and corresponds to its severity. The compensatory activation of the trypsin inhibitors is directed to increasing the resistance of the body to trypsinemia. Deficiency of the inhibition system leads to activation of organic proteolysis and growth of the content of middle-molecular peptides in the blood. Such a character of homeostasis disorders substantiates the need for the search for effective measures of correction of the trypsin-antitrypsin system and freeing the organism of the excess of middle-molecular molecules.
