Xenon tissue/blood partition coefficient for pig urinary bladder

Abstract

In four landrace pigs the tissue/blood partition coefficient (lambda) for xenon (Xe) for the urinary bladder was calculated after chemical analysis for lipid, water and protein content and determination of the haematocrit. The coefficients varied from bladder to bladder owing to small differences in both the haematocrit and tissue composition. In Xe washout studies of the blood flow of the urinary bladder, we recommend calculating the lambda for Xe from the actual haematocrit and from the median value of tissue composition found in the present study.
