Effect of phlorhizin on a dog with Eck fistula. 

 By N. B. Foster. 



It has been stated by Rosenfeld that the administration of 

 phlorhizin to dogs with Eck fistula does not induce glucosuria. 

 This observation would have so much bearing upon our ideas of 

 the mode of action of phlorhizin that the subject required con- 

 firmatory evidence. 



One gram of phlorhizin in olive oil emulsion was given to a dog 

 on which an Eck fistula had been done. Glucose was found in the 

 urine in considerable quantity for nine days subsequent to the 

 phlorhizin adminstration.

On elimination through the mucosa of the urinary bladder. 



By Israel S. Kleiner. 



[From the Department of Physiology and Pharmacology of the 

 Rockefeller Institute for Medical Research.] 



In a previous communication (Journal of Exper. Medicine, 

 XIV, 274, 191 1), I stated that after intravenous injections of large 

 amounts of dextrose the intestine contained on the average 1.2 per 

 cent, of the injected amount of destrose and in nephrectomized 

 animals the dextrose content of the intestine reached the average 

 of 2.2 per cent. The question arose then whether in the presence 

 of a strong hyperglycemia, and especially after double nephrec- 

 tomy, all mucous membranes are slightly permeable to this 

 substance. The presence of measurable quantities of dextrose in 

 the gastro-intestinal canal is no evidence for the permeability of 

 the mucosa as such, since the mucous membrane of this organ is 

 studded with numerous glandular structures which may readily
