PRESSOR PATHWAYS NOT BLOCKED BY TETRAETHYLAMMONIUM

Abstract
Stimulation of the spinal cord below the level of a transection was performed in curarized dogs, rab-bits, cats, and monkeys under barbiturate anesthesia. The resulting rise of arterial pressure was prevented by tetraethylam-monium in the cat and monkey, but not in the rabbit and dog. The pressure rise was prevented by the adrenergic blocking agent, SY-28, in all species. In the dog, the vasomotor pathways not vulnerable to ganglionic blocking agents were shown to leave the cord by way of the ventral roots.
