Overview

Indicates mature renin secretion in newborn dogs; extends developmental physiology but leaves open human translation.

Structured PICO

P
Population
Newborn dogs during the first 15 days of extrauterine life
I
Intervention
Stimulation of renin release via peritoneal dialysis
C
Comparator
Adult dogs (for baseline comparison) and unstimulated state
O
Outcome
Plasma renin activity, renal renin activity, and juxtaglomerular indexsurrogate

The formation and secretion of renin is well developed in the kidneys of newborn dogs despite the absence of demonstrable juxtaglomerular cell granules.
