Abstract

  1. 1.

    Renal handling of pig-and rat-insulin was studied in the isolated perfused rat kidney.

     
  2. 2.

    Metabolic clearance rates of both pig- and rat-insulin excceded GFR.

     
  3. 3.

    Peritubular uptake of pig-insulin accounted for 13%, of rat-insulin for 31% of the total metabolic clearance.

     
  4. 4.

    The nonfiltering kidney does not remove insulin from the peritubular circulation.

     
  5. 5.

    Metabolic clearance rates of pig- and rat-insulin are directly related to GFR.

     
  6. 6.

    The filtration process seems to be necessary for the uptake of insulin at the peritubular site.
