Table 1 Five-hour total urine volumes (mL) and urinary recovery (%) of orally ingested lactulose (5 g) and L-rhamnose (0.5 g) in four experimental conditions (n = 33).

From: Effects of oral adenosine 5'-triphosphate and adenosine in enteric-coated capsules on indomethacin-induced permeability changes in the human small intestine: a randomized cross-over study

Experimental condition Recovery (%) Median (interquartile range) Urine volume (mL) Median (interquartile range)
  Lactulose Rhamnose  
Control 1 0.14 (0.08–0.22) 4.41 (3.31–5.88) 298 (182–613)
Indomethacin + placebo 0.20 (0.11–0.31)* 4.60 (3.15–5.91) 324 (193–493)
Indomethacin + ATP 0.18 (0.12–0.32)* 4.12 (3.23–4.89) 371 (165–518)
Indomethacin + adenosine 0.23 (0.11–0.28)* 4.52 (3.90–5.26) 307 (213–563)
  1. 1No indomethacin, no placebo/ATP/adenosine
  2. Differences in lactulose/rhamnose recovery and urine volumes between the conditions with indomethacin plus placebo, ATP or adenosine were not significant
  3. *P < 0.01 vs. control (Wilcoxon signed ranks test)
