[Effect of antiadrenergic and myotropic hypotensive agents on the blood kallikrein-kinin system in experimental hypertension].

In the period of vasorenal hypertension formation in rats phase changes in the kallikrein-kinin system of the blood are observed: one month after kidney-skin anastomosis a significant increase of the levels of prekallikrein, kininogen and kallikrein inhibitor is noted and by the end of the second month a drastic decrease of the levels of these components occurs due to the "unregulated" activation of the kallikrein-kinin system of the blood. Antiadrenergic agents (reserpine, tropaphen) prescribed for treatment of hypertension prevent the development of the "unregulated" activation of the kallikrein-kinin system and reduce consumption of its components. These drugs are advisable to use under threat of the kallikrein-kinin system exhaustion. beta-adrenoblocking agent obsidan and myotropic drugs produce a significant enhancement of kallikreino- and kininogenesis, but the degree of activation of the processes is less pronounced than in untreated hypertensive rats.
