title: Renin disappearance rate in puppies.
abstract: The disappearance rate of endogenous renin from the circulating blood after bilateral nephrectomy was studied in 4 puppies aged 16-21 days. Mean half-times of the fast and slow component of the disappearance curves of renin were 9.15 min +/- 0.87 (SD) and 84.0 min +/- 16.8 (SD), respectively. These values are not different from the values reported for adult dogs in the literature. The metabolic degradation of renin is not different between young and adult dogs and does not contribute to the elevated plasma renin activity in the puppy.
