[Combined reactions of the cerebral and renal vessels to the action of hypertensive and hypotensive agents].
The action of noradrenaline (0.1-10 micrograms/kg), angiotensin (0.1-10 micrograms/kg), hemiton (30 micrograms/kg) and apressin (1 mg/kg) on the resistance of cerebral and renal vessels was studied in anesthesized cats by the two-channel resistography technique. It has been established that noradrenaline and angiotensin produce a synchronous vasoconstrictive effect in these organs, with the reaction to noradrenaline being less pronounced in renal vessels than in cerebral ones. Hemiton and apressin induce a stable vasodilatation in the brain and kidneys and attenuate vascular reaction to noradrenaline and angiotensin injections.
