[Kallikrein-kinin system of the kidneys and blood in hypertension and chronic pyelonephritis].

Comparative study of the renal and blood kinin system in patients with hypertensive disease and in those with chronic pyelonephritis revealed its different reaction to a similar character of arterial pressure in these patients, which suggests that the kinin system differs in its significance in the pathogenesis of hypertension in these diseases. It is recommended to use the values of the renal and blood kinin system in practice for the differential-diagnostic purpose in the planned stage-by-stage examination of patients with arterial hypertension.
