Thomas D. Boyer, Dennis D. Kokenes, Gary Hertzler, Michael H. Kutner, J. Michael Henderson – 1 December 1994 – Distal splenorenal shunt is known to effectively control bleeding from esophageal and gastric varices; however, the effect of this selective shunt on liver function is less well understood. We examined retrospectively the effect of distal splenorenal shunt on the survival of 19 patients with primary biliary cirrhosis subjected to surgery for bleeding varices over a 20‐yr period and had been followed for at least 1 yr.

Lesley Helyar, Daniela S. Bundschuh, Jeffrey D. Laskin, Debra L. Laskin – 1 December 1994 – Nitric oxide is a highly reactive mediator released in the liver by hepatocytes, Kupffer cells and endothelial cells during endotoxin‐induced inflammation. In this study we determined whether Ito cells also produce nitric oxide after exposure to endotoxin. For induction of endotoxemia, rats were injected intravenously with Escherichia coli lipopolysaccharide (2.5 mg/kg).

Stelios Karatapanis, P. Aiden McCormickM.D.MRCP, Shilpa Kakad, Jason K. T. Chin, Mohammed Islam, Jamie Jeremy, David Harry, Neil McIntyre, Andrew K. Burroughs, Michael Jacobs – 1 December 1994 – It has been suggested that increased production of nitric oxide by an inducible nitric oxide synthase isoenzyme is important in the pathogenesis of the vascular abnormalities seen in human beings and animals with portal hypertension. We investigated this hypothesis by studying the in vitro vascular reactivity of isolated aortic rings from portal vein—constricted and sham‐operated rats.

Steven A. Weinman – 1 December 1994 – Using expression cloning in Xenopus laevis oocytes, we have isolated a cDNA encoding a rat liver organic anion‐transporting polypeptide (oatp). The cloned oatp mediated Na+‐independent uptake of sulfobromophthalein (BSP) which was Cl−‐dependent in the presence of bovine serum albumin (BSA) at low BSP concentrations (e.g., 2 μM). Addition of increasing amounts of BSA had no effects on the maximal velocity of initial BSP uptake, but it increased the Km value from 1.5 μM (no BSA) to 24 μM (BSA/BSP molar ratio, 3.7) and 35 μM (BSA/BSP ratio, 18.4).

Antoinette Lemoine, Daniel Azoulay, Ashley Dennison, Liliane Kiffel, Lydiane Pichard, Valérie Furlan, Thierry Bienvenu, Gilles Fredj, Brigitte Debuire, Patrick Maurel, Henri Bismuth, Philippe Beaune – 1 December 1994 – Many commonly used drugs are substrates for hepatic cytochrome P‐450 3A in human beings, and its role in the metabolism of potentially toxic immunosuppressants has been highlighted (cyclosporine, FK 506).

Catherine M. St. George, James C. Russell, Eldon A. Shaffer – 1 December 1994 – Obesity, a known risk factor in cholesterol gallstone disease, is a favorable factor in the formation of bile supersaturated with cholesterol. Previous studies have been indirect and limited to human beings. To better define the hepatic secretory defect, we directly measured bile secretion and bile salt kinetics in a genetically obese rat.
