Intestinal permeability of humans and three species of experimental animals was assessed by the oral administration of the three non-metabolizable sugars: lactulose, rhamnose and mannitol and collecting all the urine produced in a specified time. The total percentage recovery of the permeability markers was determined by high performance liquid chromatographic assays of urinary aliquots. The permeability of the human gut to mannitol was substantially greater than that of rats, guinea pigs, or hamsters (18-, 6- and 29-fold increases, respectively). The permeability to lactulose in humans was somewhat less than that found in guinea pigs (P less than 0.05), but three times greater than that found in rats or hamsters (P less than 0.001). Human rhamnose permeability was substantially greater than that of rats, guinea pigs or hamsters (6-, 2.5-, and 7-fold increases, respectively). The results suggest that the permeability of the human gut to probe molecules is considerably different from that of three common laboratory rodents, but is closest to that of guinea pigs. Possible species differences in the physiological factors which control permeability are discussed.
