Use of a 13C-aminopyrine blood test: first clinical impressions.

The purpose of this study was to collect initial data to determine the potential clinical usefulness of a 13C-aminopyrine demethylation blood test, and whether additional clinical investigation is warranted. Six dogs, initially suspected of having hepatic disease based on their history, physical examination, imaging studies, general laboratory parameters, or any combination of the above, were enrolled in the study. A baseline blood sample was collected, 2 mg/kg 13C-aminopyrine was administered intravenously, and another blood sample was collected 45 min afterwards.

Kinetics of urinary recovery of five sugars after orogastric administration in healthy dogs.

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.
