The purpose of this study was to determine the 12-h fasting preprandial and 2-h postprandial serum bile acid concentration (SBAC) reference intervals for healthy, adult rhesus macaques (Macaca mulatta). We hypothesized that the mean 2-h postprandial SBAC would be significantly higher than the mean preprandial SBAC. We included 40 (24 male, 16 female) macaques after confirming that their health records, physical examinations, CBC, serum chemistry panels, and urinalyses were all within normal limits. In addition, hepatitis A titers were determined, an ultrasound examination of the liver was performed, and two 16-gauge ultrasound guided percutaneous liver biopsies were collected and submitted for histopathology. Macaques were confirmed healthy according to hepatitis A screens and sonographic and histologic evaluation of hepatic tissue. Within 2 wk of the screening procedures, preprandial and postprandial SBACs were measured. Preprandial SBAC (mean ± 1 SD) was 11.1 ± 1.9 μmol/L and postprandial SBAC was 19.7 ± 8.0 μmol/L, which was significantly higher than the preprandial value. Sex and hepatitis titers did not significantly influence preprandial and postprandial SBAC. The current study indicates that the SBAC reference values for rhesus macaques are higher than those reported for humans and companion animals.

D001647 Bile Acids and Salts Steroid acids and salts. The primary bile acids are derived from cholesterol in the liver and usually conjugated with glycine or taurine. The secondary bile acids are further modified by bacteria in the intestine. They play an important role in the digestion and absorption of fat. They have also been used pharmacologically, especially in the treatment of gallstones. Bile Acid,Bile Salt,Bile Salts,Bile Acids,Acid, Bile,Acids, Bile,Salt, Bile,Salts, Bile
