Resumo
An increase of total glucagon-like peptide-1 (GLP-1) concentration in the plasma in rats was revealed 5 min after oral, but not intraperitoneal administration of NaCl or Trizma HCl solutions. The increase in GLP-1 level was similar to that after oral glucose administration. After intraperitoneal administration of 2.5% NaCl, GLP-1 mimetic exenatide accelerated natriuresis and urinary chloride excretion. Under conditions of normonatriemia and hyperchloremia induced by injection of 6.7% Trizma HCl, exenatide stimulated chloride excretion and reabsorption of sodium ions in the kidneys. These findings suggest that GLP-1 participates in selective regulation of the balance of sodium and chloride ions.
