Development of a solid-phase enzyme immunoassay for ursodeoxycholic acid: application to plasma disappearance of injected ursodeoxycholic acid in the rabbit.
A bile acid disappearance test using an enzyme immunoassay for ursodeoxycholic acid (UDCA) is presented. The immunoassay employs an antiserum produced in rabbits with UDCA coupled by amide linkage to egg albumin. An antigen (UDCA)-enzyme (beta-D-galactosidase) complex was prepared by adding the N-hydroxy-succinimide ester of UDCA to beta-D-galactosidase in a molar ratio of 5000:1. The anti-UDCA...
متن کاملUrsodeoxycholic acid
Ursodeoxycholic acid is an epimer of chenodeoxycholic acid (DB06777). It is a mammalian bile acid found first in the bear and is apparently either a precursor or a product of chenodeoxycholate. Its administration changes the composition of bile and may dissolve gallstones. It is used as a cholagogue and choleretic. [PubChem] Indication: The drug reduces cholesterol absorption and is used to dis...
متن کاملApplication of ursodeoxycholic acid in hepatobiliary scintigraphy for neonatal hyperbilirubinemia: Comparison with phenobarbital
Introduction: Early differentiation of biliary atresia from neonatal hepatitis is of utmost importance, since on time surgery of biliary atresia significantly improves the outcome. Hepatobiliary scintigraphy is an integral part of diagnosis work-up of these patients; however its specificity for diagnosis of biliary atresia is suboptimal. In this study we evaluated t...
متن کاملMolecular Mechanisms of Ursodeoxycholic Acid Toxicity & Side Effects: Ursodeoxycholic Acid Freezes Regeneration & Induces Hibernation Mode
Ursodeoxycholic acid (UDCA) is a steroid bile acid approved for primary biliary cirrhosis (PBC). UDCA is reported to have "hepato-protective properties". Yet, UDCA has "unanticipated" toxicity, pronounced by more than double number of deaths, and eligibility for liver transplantation compared to the control group in 28 mg/kg/day in primary sclerosing cholangitis, necessitating trial halt in Nor...
متن کاملRadioimmunoassay of ursodeoxycholic acid in serum.
A sensitivie and specific radioimmunoassay for the measurement of serum ursodeoxycholic acid has been developed. Ursodeoxycholic acid bound to bovine serum albumin was used as an antigen, and antiserum to this antigen was raised in the rabbit. [11, 12-3h2]Ursodeoxycholic acid was used as the radioactive tracer, and the radioimmunoassay was carried out by the method of Simmonds et al. (1973. Gas...
