The Effect of Hemorrhage on the Noradrenaline and Adrenaline Contents of the Adrenal Gland in the Cat

Abstract

The present investigation was attempted to know the influence of bleeding on the adrenal noradrenaline and adrenaline contents of the cat. Noradrenaline and adrenaline contents of the adrenal gland were estimated by the permanganate method of Suzuki and Ozaki.
After the bleeding of two-fifths of the total blood quantity a decrease in adrenaline content of the adrenal gland was found. However, there was no modification of adrenal noradrenaline content.
In cats, in which the bleeding of two-fifths plus one-fifth of the total blood quantity was performed, a marked depletion of adrenaline content and a slight decrease in noradrenaline content of the adrenal gland were found.
