The catechol amine content of various organs of the cat after injections and infusions of adrenaline and Noradrenaline.

Infusions of 2.5-7.8 ng. noradrenaline/Kg./min. over 30 min. and intruperitonenl injections of noradrenaline and adrenaline up to 2000 Mg/Kg. in the cat had no effect on the catechol amine content of the. heart, spleen, liver, kidney and skeletal muscle, except for a slight increase in the adrenaline content. It is concluded that these organs lack the ability to accumulate i-iirulating catechol amines administered in physiologic dosage.
