EFFECTS OF GLUCAGON ON RENAL FUNCTION IN MAN*

Abstract
The effect of glucagon on renal hemodynamics and clearance of electrolytes in 20 normal men is reported. An enhancing effect on sodium, chloride, potassium and inorganic phosphorus clearance ratios was observed. It is suggested that the electrolyte effect of glucagon is probably due to a tubular action, though a glomerular effect has not been completely ruled out. Evidence is presented that these effects are not secondary to the hyperglycemic action of glucagon or to an inhibition of carbonic anhydrase.
