Abstract
Natrium nitrite, a vasodilatatory principle, was given intravenously in doses of 20. 30 and 40 mgrms. (about lethal) per kilo of body weight to the dogs prepared for collected blood from the suprarenal capsule without fastening, narcotizing nor evoking pain. Epinephrine was measured by means of the rabbit intestine segment.
The epinephrine output rate was accelerated definitely in every case, from three to ten times the initial rate, and the period covering an augmented secretion almost corresponded to the depressoric phase.
Hyperglycaemia was observed only in a single case out of four.
