The influence of bradykinin on carotid baroreceptors in vitro.

The actions of bradykinin on isolated and superfused carotid baroreceptors have been examined. Bradykinin was applied either locally, in the organ bath, in doses of 9 microng, or by superfusion in doses of 0.8 - 0.9 microng/ml saline. The results have shown that bradykinin has no effects upon the activity of baroreceptors.
