[The sugar decreasing effect of several insulin polymer derivatives following enteric administration to aniamls]

An experimental study of the hypoglycemic action of polymeric derivatives of insulin was carried out by its enteral administration through a gastric tube into the stomach and into the oral cavity on 105 intract rabbits. A marked hypoglycemic effect significantly differing from the action of crystalline insulin was produced by enteral administration of insulin modified with polymeres. Changes in the character of binding of the protein with the polymere, of the molecular weight of the polymere and of its chemical nature proved to influence the value and the duration of action of insulin modified by polymeres.
