Role of prostaglandin E2 in regulation of urine excretion in saluresis, water and osmotic diuresis in rat

In the saluresis, water and osmotic diuresis were indicating an increase of prostaglandin E2 excretion and a correlation between this index and diuresis. Unselective blockade of cyclooxygenase by diclofenac-natrium leads to a decrease of diuresis in the observed types of urine-production in rats. Inhibition of inducible cyclooxygenase by celebrex didn't change the value of diuresis after water load or administration of osmotic agent, but decreased the diuretic effect of furosemide.
