Abstract
The administration of glucose to depancreatised dogs deprived of food and insulin for 3 days leads to no change in the inorganic P excretion in the urine. Since in a previous communication it was shown that the administration of glucose or insulin to normal fasting animals causes striking changes in the P output in the urine, the author concludes that changes in the urinary phosphate in relation to carbohydrate metabolism is related to the action of insulin.
