Abstract
Summary
The acute response in aldosterone and cortisol secretion in continuous progressive hemorrhage was studied in two series of dogs. In series A (N = 6), the animals were anesthetized, the catheters were inserted for collecting adrenal venous blood and recording pressure and the acute experiment was performed. In series B (N = 5), the adrenal venous catheter was placed 3 days before the acute experiment was done to minimize the effects of surgical stress on ACTH release and steroid secretion. In both series of animals, a clear-cut monophasic response to hemorrhage was observed for both aldosterone and cortisol secretion.
