Induction of Taurocholate Release from Isolated Rat Hepatocytes in Suspension by α‐Adrenergie Agents and Vasopressin: Implications for Control of Bile Salt Secretion

David A. Gewirtz, Joyce K. Randolph, I. David Goldman – 1 March 1984 – Hepatocytes incubated with 25 μM. [3H]taurocholate rapidly deplete the extracellular medium of [3H]taurocholate and achieve a steady‐state level of intracellular bile salt within 15 min. Exposure of cells at steady state ith extracellular taurocholate to the catecholamines norepinephrine or epinephrine results in release of 3H from the cells into the incubation medium; the 3H released represents almost exclusively unmetabolized [3H]taurocholate.

Liver Membrane Antibodies Detected by Immunoradiometric Assay in Acute and Chronic Virus‐Induced and Autoimmune Liver Disease

K. H. Wiedmann, T. C. Bartholemew, D. J. C. Brown, Howard C. Thomas – 1 March 1984 – In this study, we describe a radioimmunoassay to detect liver membrane binding antibodies. The assay was designed to exclude binding of aggregated IgG or immune complexes to Fc 7 receptors of hepatocytes. When this assay was applied to sera from 142 patients, antibodies were found in highest titer in patients with autoimmune chronic active hepatitis, rarely in patients with hepatitis B virus‐induced chronic active liver disease, and in 32% of patients with primary biliary cirrhosis.

Biochemical and Morphological Alterations of Baboon Hepatic Mitochondria After Chronic Ethanol Consumption

Masao Arai, Maria A. Leo, Masayuki Nakano, Ellen R. Gordon, Charles S. Lieber – 1 March 1984 – Baboons fed ethanol (50% of total calories) chronically develop ultrastructural alterations of hepatic mitochondria. To determine whether mitochondrial functions are also altered, mitochondria were isolated from nine baboons fed ethanol chronically and their pair‐fed controls. At the fatty liver stage, ADP‐stimulated respiration was depressed in ethanol‐fed baboons by 59.4% with glutamate, 43.2% with acetaldehyde, 45.1% with succinate and 51.1% with ascorbate as substrates.

An Antibody Which Precipitates Dane Particles in Acute Hepatitis Type B: Relation to Receptor Sites Which Bind Polymerized Human Serum Albumin on Virus Particles

A. Alberti, P. Pontisso, E. Schiavon, G. Realdi – 1 March 1984 – An antibody, which is distinct from the HBsAg, and reacts with antigenic sites on Dane particles HBcAg and HBeAg, was studied by radioimmunoprecipitation of radioactive intact hepatitis B virions in sera obtained early in the course of acute hepatitis type B. The antibody, previously termed anti‐Dane particle (anti‐DP) antibody, was reactive with Dane particles and HBsAg particles obtained from HBeAg‐positive sera but not with HBsAg particles from anti‐HBe containing sera.

(+)‐Cyanidanol‐3 in the Treatment of Acute Viral Hepatitis: A Randomized Controlled Trial

Hans Schomerus, Karl H. Wiedmann, Wolfgang Dölle, Herrmann Peerenboom, Georg Strohmeyer, Klaus Balzer, Harald Goebell, Hans K. Dürr, Christian Bode, André L. Blum, Gert Frösner, Wolfram Gerlich, Peter A. Berg, Klaus Dietz – 1 March 1984 – One‐hundred sixty patients (81 cyanidanol, 79 placebo) were included in a double‐blind placebo‐controlled clinical trial to evaluate the effect of 3 gm (+)‐cyanidanol‐3 per day for 8 weeks on the clinical course of acute viral hepatitis and HBsAg elimination. Quantitative determination of HBsAg was performed at frequent intervals.

A Nonhuman Primate Model of Gilbert's Syndrome

Oscar W. Portman, Jayanta Roy Chowdhury, Namita Roy Chowdhury, Manfred Alexander, Charles E. Cornelius, Irwin M. Arias – 1 March 1984 – A Bolivian population of squirrel monkeys, Saimiri sciureus, exhibits several features of Gilbert's syndrome in man, and is proposed as a nonhuman primate model of the condition. The Bolivian population was found to have higher fasting (40.6 ± 2.7 μM; mean ± S.E.) and postcibal (9.9 ± 0.9 μM) plasma unconjugated bilirubin concentrations (p < 0.001) than a closely related Brazilian population (fasting 5.5 ± 0.7 μM); postcibal (2.4 ± 0.7 μM).
