Elimination of Dextrose.

are: for the intestines 0.05 g. and for the stomach 0.1 g. In 
a second series six animals received by intravenous infusion 
7 grams dextrose per kilo body-weight (in about molecular 
concentration). The average duration of the infusion was 
about half an hour; fifteen minutes later the animal was killed, 
the intestines were washed out and the stomach removed. 
The averages were: for the intestines 0.16 g. = 1.4 per cent, and 
for the stomach 0.13 g. = 1.1 per cent, of the injected dextrose. 
During the period between the beginning of the infusion until the 
animal was killed for the purpose of washing out the intestines an 
average of 39 per cent, of the injected dextrose was eliminated 
in the urine. In a third series of six rabbits only 4 grams of dex- 
trose per kilo were injected (in about 0.6 molecular concentration). 
The average of this series amounted for the intestines to 0.11 g. = 
1.9 per cent., and for the stomach 0.08 g. = 1.1 per cent, of the 
injected dextrose. Through the urine 23 per cent, of the injected 
dextrose was eliminated. In the fourth series of rabbits double 
nephrectomy was performed and on the following day 7 grams of 
dextrose per kilo were infused. The averages of this series are as 
follows: for the intestines o. 24 g. = 2.1 per cent, and for the stomach 
0.15 g. = 1.3 per cent, of the injectedd extrose. Finally in a 
series of only three nephrectomized rabbits the stomach and the 
intestines were examined on the following day without a preceding 
infusion of dextrose. Only a mere trace of dextrose could be dis- 
covered in these instances. These animals partook of very little 
food after nephrectomy. 
Our experiments have shown that the stomach and especially 
the small intestines of rabbits contain measurable quantities of 
dextrose even when the food is poor in easily convertible carbo- 
hydrates; that an intravenous injection of dextrose increases per- 
ceptibly the gastro-intestinal dextrose even without the aid of a 
simultaneous infusion of sodium chloride, and that nephrectomy in- 
deed increases the elimination of infused dextrose. However, con- 
sidering the high elimination of the injected dextrose through 
the urine, the comparatively insignificant increase of elimination 
into the gastro-intestinal canal after nephrectomy can hardly 
be looked upon as a functional assumption of the activities of the 
kidney, as a vicarious phenomenon.
