Abstract

Morphometric analysis was carried out on kidneys of neonatal dogs in which function of the entire kidney and of single nephrons had been evaluated. Measurements were begun after neogenesis of nephrons had been completed, i.e., at the end of the 3rd postnatal wk. They were continued to 74 days by which time glomerular function, expressed per unit of renal weight, had reached the mature level. For statistical analysis, the cortical histogram at each age was divided into eight zones of equal depth between the capsule and corticomedullary junction.
