A carrier‐protein receptor is not a prerequisite for avid hepatic elimination of highly bound compounds: A study of propranolol elimination by the isolated perfused rat liver

D. Brian Jones, Michael S. Ching, Richard A. Smallwood, Denis J. Morgan – 1 July 1985 – The highly efficient hepatic extraction of propranolol by the isolated perfused rat liver does not diminish when albumin binding is increased from 30 to 75%. One possible explanation of this insensitivity of propranolol uptake to changes in albumin binding is the mediation of uptake of bound ligand by an albumin receptor on the hepatocyte as postulated for oleate, taurocholic acid and rose bengal.

Effects of anesthetic agents on bile pigment excretion in the rat

Glenn R. Gourley, William Mogilevsky, Richard A. Arend, Frank L. Siegel, Gerard B. Odell – 1 July 1985 – Anesthesia‐induced alterations in bilirubin conjugation were studied. Rats were fitted with bile duct and jugular vein catheters while anesthetized with diethyl ether, ketamine or pentobarbital. As anesthesia abated, bile was collected for the next 5 hr and analyzed for flow rate, total bilirubin excretion and bilirubin glucuronide composition. The high‐performance liquid chromatography method used allowed direct analysis of bile without derivatization or extraction.

Endoscopic sclerosis and esophageal balloon tamponade in acute hemorrhage from esophagogastric varices: A prospective controlled randomized trial

Karl‐Joseph Paquet, Hubertus Feussner – 1 July 1985 – A prospective randomized controlled clinical trial was performed in 43 consecutive histologically proved cirrhotic patients with endoscopically proved actively bleeding esophageal varices. Twenty‐two were randomly selected to have esophageal tamponade with the Sengstaken‐Blakemore tube, and 21 were selected to have endoscopic sclerosis of the esophageal wall.

The spectrum of complement‐fixing antinuclear antibodies in patients with hepatocellular carcinoma

Kendo Kiyosawa, Richard J. Daemer, Li‐Fang He, Ferruccio Bonino, O. W. Prozesky, Robert H. Purcell – 1 July 1985 – Sera from 230 hepatocellular carcinoma patients were tested for antinuclear antibodies by anticomplement immunofluorescence in 16 types of transformed, diploid or primary cells of human, monkey, chimpanzee or rat origin. As controls, we tested 85 sera from patients with chronic liver diseases, 48 sera from patients with nonhepatic cancers and 164 sera of normal controls.

Effect of systemic pH, PCO2 and bicarbonate concentration on biliary bicarbonate secretion in the rat

Michèle Corbic, Cristina Muñoz, Micheline Dumont, Ghislaine De Couët, Serge Erlinger – 1 July 1985 – The effect of acute metabolic or respiratory acid‐base disturbances on biliary bicarbonate secretion was examined in bile fistula rats. Animals were infused with ursodeoxycholate at a rate that stimulates bicarbonate secretion (1 μmole · min−1 · 100 gm−1), in control conditions and during acute acid‐base disturbances.

Recombinant leukocyte interferon treatment of chronic hepatitis B

Geoffrey Dusheiko, Adrian Dibisceglie, Sheila Bowyer, Evelyn Sachs, Marian Ritchie, Barry Schoub, Michael Kew – 1 July 1985 – We have investigated the efficacy of a relatively prolonged course of recombinant leukocyte interferon treatment in 14 chronic HBsAg‐, HBeAg‐, hepatitis B virus DNA‐ and DNA polymerase‐positive carriers. α‐Interferon was administered for 9 weeks. Six of 14 treated carriers have a sustained loss of HBeAg, hepatitis B virus DNA and DNA polymerase. Four subsequently lost HBsAg (28.5%).
