Abstract
Summary
(1) Blood pressure responses to cold-pressor test were studied in progeny of spontaneously hypertensive rabbits. These animals were both hypertensive and normotensive. Controls were offspring of rabbits chosen from normotensive laboratory stock. (2) Average maximum blood pressure response to cold stimulation of progeny of spontaneously hypertensive rabbits was quantitatively greater than in the control group. This difference in responsiveness was not attributable to difference in basal (starting) pressure. (3) It is concluded that increased pressure response to cold is a characteristic of progeny of spontaneously hypertensive rabbits.
