Why the study?
Does the kidney, via the renin-angiotensin system, mediate the stimulation of aldosterone secretion in response to hemorrhage in hypophysectomized dogs?
Does the kidney, via the renin-angiotensin system, mediate the stimulation of aldosterone secretion in response to hemorrhage in hypophysectomized dogs?
The study demonstrates that the kidney and the renin-angiotensin system play a crucial role in mediating aldosterone secretion in response to hemorrhage.

Renal control of aldosterone in experimental hemorrhage warrants mechanistic follow-up; leaves open translation to human hypovolemia.
In summary, these data show that in hypophysectomized dogs: 1. Hemorrhage stimulates mainly aldosterone secretion. 2. Nephrectomy prevents stimulation of aldosterone secretion by hemorrhage. 3. Nephrectomy lowers basal secretion of aldosterone. 4. Crude saline extracts of dog kidneys, semipurified renin extracts of dog kidneys, and synthetic angiotensin can stimulate aldosterone secretion. These findings suggest that in hypophysectomized dogs, the kidney, via the renin-angiotensin system, is an important mechanism by which hemorrhage stimulates aldosterone secretion.
