Blood sugar curves with glucose, lactose, maltose, mannite, and 



cane sugar. 



By Cyrus W. Field. 



These curves were obtained by feeding normal males colored, 

 with 100 grams of the pure sugar, on a fasting stomach. The 

 dose was as a rule given after the first sample of blood had been 

 taken; this was as a rule at 8 A.M. The second, third and fourth 

 samples were taken one, two and three hours after the ingestion 

 of the sugar, which had been dissolved in a large glass of water. 



The urines were tested for glucose up to three hours after the 

 last sample of blood had been taken, and in none of the cases did 

 a specimen ever show the slightest trace of a reducing substance 

 with Benedict's qualitative solution. 



The glucose curve was that with which all are familiar, that 

 is rising to its highest point one hour after the ingestion, and then 

 dropping to the normal at the end of the next hour or two. 



Maltose gave the same curve as the glucose. Mannite gave 

 the same time curve as the glucose, and maltose, but did not rise 

 to the same height as the other two ; the average of five cases gave 

 an increase of only 10 milligrams per 100 c.c. of blood, while that 

 for glucose was 40 milligrams, and for maltose 34 milligrams. 



Cane sugar showed a curve that reached its height at the end 

 of the second hour after its ingestion, and had dropped to normal 

 at the third hour. Its average rise for 10 cases was 20 milligrams
