Abstract
The suprarenal vein blood was sampled. in non-anesthetized dogs and the adrenaline in the suprarenal vein blood was. estimated by the rabbit intestine segment method. Potassium cyanide was. injected in a dose of 1.0-2.5mg. per kg. intravenously or 1.5-4.0mg. per kg. subcutaneously.
After injection when the symptoms of cyanide poisoning were mani-fested, the secretion of adrenaline accelerated decidedly. An enormously accelerated adrenaline secretion such as 1.9 γ per kg. per minute was able to observe in the cases, in which potassium cyanide was injected in a dose of 2.0mg. or 2.5mg. per kg. intravenously.
