[Resorbate kinetics in the pre- and posthepatic blood compartment in the immediate postoperative phase in swine]

Catheters were implanted in the portal vein by the superior mesenteric vein in pigs for valuation of the absorbant kinetics of enterically applied substances in the mesenteric veins. The blood level kinetics after applying 10 g D-xylose into the jejunum was measured continuously simultaneously in the pre- and posthepatic blood compartment 6, 24, 36, 48, and 72 hours after the operative procedure. An enteric resorption of the pentose is provable already 6 hours after the operation, with their utter normalization in the next 36 hours. The differences between the pre- and the posthepatic concentration-time-graphs admits conclusions on the metabolism of the absorbant in the liver.
