[Kallikrein-kinin system of the blood plasma in patients with infectious-allergic myocarditis].

The state of the blood plasma kallikrein-kinin system in infectious-allergic myocarditis was studied for the first time. Biological methods for the determination of kallikrein, kininogen, kininases, and free kinins were used. Changes in the activity of the kinin system were revealed in 92% of 38 individuals examined: activation in the first 2-4 months and exhaustion later (in 6-8 months).
