The Peripheral Vascular Reactivity of Potassium-Deficient Rats

RAY H. ROSENMAN M.D.1; S. CHARLES FREED M.D.1; MEYER FRIEDMAN M.D.1

1 From the Mount Zion Hospital, the Harold Brunn Institute for Cardiovascular Research, San Francisco, Calif.

Peripheral vascular reactivity was studied in the potassium-deficient and control rats by measuring the degree of blood pressure response to intravenously injected pressor substances. The pressor response consistently was less in the potassium-deficient rats. The significance of these results with regard to the hypotensive action of potassium deprivation is discussed.
