Abstract
Intra-aortic injections of a wide variety of agents have been investigated with respect to their abilities to produce epinephrine discharge as judged by increments in heart force, blood pressure and heart rate.
General anesthesia markedly reduced the responsiveness of the adrenal medulla to nicotine, potassium chloride and calcium chloride.
Moderate degrees of hypoxia did not significantly influence the responses to nicotine and potassium chloride.
