  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...

flutamide is a non-steroidal antiandrogen commonly used in the treatment of prostate cancer. severe hepatotoxicity occurs in few patients, yet may be fatal. to date, none of the reported cases of flutamide hepatotoxicity has demonstrated thrombocytopenia and chronic liver disease. we report the case of a 55-year-old male with prostatic adenocarcinoma who developed liver failure after six months...

Background: Ursodeoxycholic acid is an important clinical drug in the treatment of liver disease. In our previous work, ursodeoxycholic acid was prepared by electroreduction of 7-ketolithocholic acid. The separation of ursodeoxycholic acid from the electroreduction product (47% (w/w) ursodeoxycholic acid) by silylation crystallization is described herein. Results: N,N-dimethylformamide was used...

We have studied the effect of ursodeoxycholic acid on the serum and urinary bile acids in seven patients with moderate to severe primary biliary cirrhosis. Bile acids were characterized by gas-liquid chromatography-mass spectrometry and quantified by capillary gas-liquid chromatography. Serum bile acids were elevated 26-fold over control values, with 2.2 times more cholic acid than chenodeoxych...

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...

The formation of ursodeoxycholic acid, the 7 beta-hydroxy epimer of chenodeoxycholic acid, was investigated in three subjects with cerebrotendinous xanthomatosis and in four subjects with gallstones. Total biliary bile acid composition was analyzed by gas-liquid chromatography before and after 4 months of treatment with 0.75 g/day of chenodeoxycholic acid. Individual bile acids were identified ...

Guinea pig gallbladder bile contains chenodeoxycholic acid (62 +/- 5%), ursodeoxycholic acid (8 +/- 5%), and 7-ketolithocholic acid (30 +/- 5%). All three bile acids became labeled to the same specific activity within 30 min after [3H]cholesterol was injected into bile fistula guinea pigs. When a mixture of [3H]ursodeoxycholic acid and [14C]chenodeoxycholic acid was infused into another bile fi...

OBJECTIVE Amyotrophic lateral sclerosis is a progressive degenerative disease, which typically leads to death in 3 to 5 years. Neuronal cell death offers a potential target for therapeutic intervention. Ursodeoxycholic acid is a cytoprotective, endogenous bile acid that has been shown to be neuroprotective in experimental Huntington and Alzheimer diseases, retinal degeneration, and ischemic and...

The present studies were conducted at the Universities of Chicago and Arizona to examine and compare the effects of supplemental dietary ursodeoxycholic acid to cholic acid, a known tumor promoter, and to piroxicam, a known chemopreventive agent, in the azoxymethane (AOM) model of experimental colonic carcinogenesis. Male Fischer 344 rats were utilized in these experiments. All animals were fed...
