Kinetics of urinary recovery of five sugars after orogastric administration in healthy dogs. Academic Article uri icon

abstract

  • OBJECTIVE: To describe the kinetics of urinary recovery (UR) of 5 sugars used for gastrointestinal permeability and mucosal function testing following orogastric administration of lactose, rhamnose, xylose, methylglucose, and sucrose. ANIMALS: 7 healthy male Beagles. PROCEDURES: A sugar solution containing lactulose, rhamnose, xylose, methylglucose, and sucrose was administered by orogastric intubation to healthy dogs. Urine samples were collected immediately before sugar solution administration (baseline) and at 2-hour intervals thereafter. The UR of the 5 sugars was determined from urine concentrations measured by high pressure liquid chromatography and pulsed amperometric detection. Percent urinary recovery (%UR) of the total UR up to 12 hours after sugar solution administration was calculated for each sugar at 2-hour intervals. RESULTS: Mean %UR exceeded 85% for all 5 sugars at 6 hours after orogastric administration of the sugar solution and exceeded 90% after 8 hours. CONCLUSIONS AND CLINICAL RELEVANCE: In healthy dogs, a urine collection period of 6 hours is sufficient for gastrointestinal permeability and mucosal function testing following orogastric administration of lactulose, rhamnose, xylose, methylglucose, and sucrose.
