STUDIES ON COLLATERAL CIRCULATION. I. THERMIC CHANGES AFTER ARTERIAL LIGATION AND GANGLIONECTOMY

Abstract

The temperature of a part of the body depends largely upon its blood supply. Under certain conditions, the temperature may there- fore be a fair measure of the circulation. With this in view, a series of experiments was planned to approach the problem of collateral circu- lation and eventually the mechanism of vasomotor action. The group of experiments here presented deals with the thermic changes occurring in the hind feet of the dog: (a) following ligation of the external iliac artery, and (b) following ligation of both external iliac arteries and unilateral removal of the tributary sympathetic ganglia.
