^893.] Chemical Changes of Sugar injected into a Vein.

Here it is seen that the quantity of sugar in the oedematous 

 fluid, as was observed in the case of the liver, is greater than in the 

 blood. 



(/) Quantity of Sugar in the Urine. In order to ascertain if sugar 

 passed out in the urine six or more hours after its injection, the 

 ligatures were removed from the ureters in five of the cases and the 

 urine passed during the following night collected. In one case only 

 was there as much as 0"06 per cent, of sugar found in the urine. Con- 

 sequently one may conclude that after sugar is injected and the 

 ureters kept ligatured six or more hours, no sugar is eliminated in 

 the form of sugar by the kidneys. The small quantity found in the 

 one case could have been derived from the exudation which had 

 accumulated in the kidneys and ureters during the time of ligature. 



3. Quantity of glycogen found in the liver and muscles after the in- 

 jection of sugar into the jugular vein. 



The results obtained from these five experiments show that the 

 quantity of glycogen met with after the injection of 10 grammes of 

 sugar per kilo, of dog's weight is well within the ordinary limits. 

 Consequently one cannot say that any very appreciable amount of 

 glycogen had been formed from the sugar that had been artificially 

 introduced into the general circulation.
