D(+)-xylose absorption test in the horse. A clinical study.
25 horses were subjected to the D(+)-xylose absorption test. 1 gram of D(+)-xylose/kg bw. was administered orally. Based upon the shape of the absorption curves the 25 patients were divided into four groups. Group 1 11 patients with a normal absorption curve (Figure 3) Group 2 5 patients with a flat absorption curve (Figure 4) Group 3 3 patients with a flat absorption curve (Figure 5) Group 4 7 patients with an intermediary type of absorption curve (Figure 6). Administration of sodium chloride in equimolar concentrations did not improve the absorption of D(+)-xylose. 73 per cent of the horses with actual or recent signs of gastrointestinal disease revealed a decreased absorption of D(+)-xylose. It is concluded that the test is valuable in the evaluation of intestinal function in the horse.
