[Pressor-depressor factors in renal vein blood in patients with renovascular hypertension].

Development of renovascular hypertension was investigated in 68 patients. Interrelated defects found in components of renal pressor-depressor system may be a contributing factor in the disease onset. Contralateral pressor-depressor system is the first to start regulating deranged regional and general hemodynamics in functional failure of the kidneys. In organic lesion occurring in the affected kidney later than in the contralateral one, there is compensatory depressor activation upon the distress of the pressor function. This may be aimed at maintenance of adequate microcirculatory blood flow and metabolism.
