THE DISTRIBUTION, FLOW, PROTEIN AND UREA CONTENT OF RENAL LYMPH

Abstract

The results of a study concerning the capsular and hilar lymph drainage of the dog''s kidney, together with the protein and urea content of renal lymph, are presented. Expts. with injs. of Evans Blue dye into the renal artery, the cortex, and the medulla, indicated that the flow of lymph was toward the capsular lymphatics from the cortex and toward the hilar lymphatics from the medulla. The detn. of the rate of flow, urea and protein content of renal lymph was made on samples obtained by direct cannulation of the renal lymphatic vessels. The protein conc. varied inversely with the rate of flow and that the conc. of urea in the renal lymph was always greater than that of the renal arterial or venous blood plasma.
