[The clinical value of determining the general antitrypsin activity of the blood and exudate in tuberculous pleurisy].

Determination of antitryptic activity of blood serum and exudate in patients with tuberculous pleurisy revealed that concentrations of trypsin inhibitors were significantly increased while their activity was markedly decreased (2-3-fold) in the exudate. This indicated exhaustion of the adaptation mechanisms in the inflammatory areas, which required their local correction. Intrapleural administration of contrical increased the body's protective and adaptation potentials and treatment efficiency such as shorter times of intoxication and pleural exudation and less frequency of pronounced concomitant pleural lesions.
