Abstract

In clinically healthy dogs, No.1, No.2, and No.3, the total value of bile acids (TBA) and conjugated bile acid fractions in the serum were measured before and 2, 4, 8, and 12 hours after meals. In addition, in clinically healthy dogs, No1, No.4, and No.5, conjugated bile acid fractions in the serum and the gallbladder were simultaneously measured after 12-hour fasting, and compared. In the first series of tests there was a high correlation between TBA values and the sum of conjugated bile acid fractions at all sampling times, and the compositional ratio of bile acids in the serum tended to be constant in each individual dog, although the values of serum conjugated bile acid fractions varied with the passage of time after each meal. In the second series of tests the compositional ratio of conjugated bile acid fractions collected from the serum was similar to the ratio from the gallbladder. From these findings, measurement of serum conjugated bile acid fractions may be useful in estimating the compositional ratio of conjugated bile acid fractions in the gallbladder, even when the period of fasting is short, for example, during an outpatient consultation.
