[The significance of the blood kinin system indices for the diagnosis of latent forms of rheumatism].

A study of the kinin and fibrinolytic systems of the blood in 280 rheumatic patients with isolated or prevailing stenosis revealed that latent forms of rheumatism were characterized by an increase of kininogenesis, reduction of kininase capacity of the blood and depression of fibrinolysis in the absence of acute-phase reactions which allows to use these data a supplementary informative test for the diagnosis of the latent course of rheumatism.
