Increased Renal Pressor Activity (Renin) in Sodium Deficient Rats and Correlation with Juxtaglomerular Cell Granulation. ∗

Abstract

Summary

Pressor activity (renin) and degree of granulation of juxtaglomerular cells (JGI) of kidneys from normal and sodium-deficient rats were measured. Pressor activity was increased in sodium-deficient animals and correlated (r = 0.80) with degree of granulation of JG cells.
