[Influence of environmental temperature on absorption of xylose in fasting animals]

The A. have studied 28 pairs of rats; 17 pairs received 1,1 g of soya oil; 7 pairs were starved. The partners were kept; one at the environmental temperature of 6 degrees C, the other at 30 degrees C. After a night, all rats were tested for xylose absorption. Xylose intestinal absorption in the rats kept at the environmental temperature of 30 degrees C after soya oil decreased of 42,88 +/- 8,14 of the value found at 6 degrees C; it decreased of 15,59 +/- 3,20% after a night of fast. Both decreases were significant (P less 0.01).
