[The activity of the components of the kinin system in renal vein blood in vasorenal arterial hypertension].

Fifty-four patients with vasorenal arterial hypertension were examined for the activity of kallikrein, prekallikrein, carboxycatepsin and renin in the blood of renal veins. In patients with an appreciable stenosing of one of renal arteries, asymmetry of kallikrein excretion due to its activity reduction was discovered on the side of the ischemized kidney. In patients with unilateral insignificant stenosis of the renal artery and bilateral stenosing of renal arteries, no consistent asymmetry in the activity of the enzymes under study was revealed.
