| Popis: |
Injection (0.05 nmol/100 g b.w.) of exenatide or its amino-acid-substituted synthetic analogs I (substitution at positions 14 and 39) and II (substitution at positions 14, 35, and 39) led to an increase in diuresis and excretion of sodium, magnesium and potassium, but only exenatide caused the excretion of solute free water. In experiments with 1% water load, only exenatide analog I stimulated the solute free water excretion. These features of exenatide and its analogs show the possibility of searching for substances with various power of action upon ion and water excretion by the kidney, which may have a clinical significance. |
