[Total proteolytic activity of the blood and its inhibitors in patients following heart operations].

The examination of 40 patients operated upon for rheumatic and congenital heart diseases has shown general proteolytic activity to be increased in patients with a rheumatic heart disease. The antitrypsin and antichymotrypsin activity were increased both in rheumatic and in congenital heart diseases. The changes were more pronounced in the development of pyo-septic and thromboembolic complications and they were found to appear earlier than clinical manifestations of the complications and can be used for prognosis of complications.

[General proteolytic activity of the blood in patients after an operation].

Changes in the level of general proteolytic activity of blood (GPAB) were studied in 32 patients after operations on lungs and organs of the abdominal cavity. The GPAB was found to elevate in 50% of patients in the postoperative period. Different pulmonary-pleural complications were detected only in this group of patients.
