Potentiating Effect of Tetraethylammonium on Pressor Response to Epinephrine and Nor--Epinephrine.

Abstract
Summary 1. The potentiation by TEA of the pressor responses to epinephrine and norepinephrine has been demonstrated in cats with spinal cord pithed. 2. The effect of epinephrine was enhanced to a greater extent than that of nor—epinephrine. 3. This potentiation was not due to the modification of homeostatic cardiovascular reflexes.
