[Disorders of the protease-antiprotease system of a bronchial washout in patients with bronchiectasis and the means for their correction].

Patients with bronchiectatic disease show imbalance between the activity of proteolytic enzymes and their inhibitors contained by bronchial wash-out, manifesting in a reduction of the inhibitory potential and a rise of the activity of trypsin-like proteinases. After the standard basic treatment the protease-antiprotease system in bronchial wash-out shows a definite improvement. Endobronchial therapy with contrykal given in a dose of 20-30 thousand ATpE for 5-7 days does not ameliorate imbalance in the protease-antiprotease system in bronchiectatic disease patients as compared to the common basic therapy.
