Ursula Hespeling, Kurt Jungermann, Gerhard P. Püschel – 1 November 1995 – Prostaglandins, released from Kupffer cells, have been shown to mediate the increase in hepatic glycogenolysis by various stimuli such as zymosan, endotoxin, immune complexes, and anaphylotoxin C3a involving prostaglandin (PG) receptors coupled to phospholipase C via a G0 protein. PGs also decreased glucagon‐stimulated glycogenolysis in hepatocytes by a different signal chain involving PGE2 receptors coupled to adenylate cyclase via a Gi protein (EP3 receptors).

Brent M. Myers, Pamela S. Tietz, James E. Tarara, Nicholas F. Larusso – 1 November 1995 – Previous investigators measuring the pH of lysosomes have used digitized video microscopy (DVM) in freshly isolated or cultured cells. Although useful, this technique is time consuming, requires the use of an image analysis system, and is limited by the fact that measurements can be made in only a relatively small number of cells.

Shu‐Ling Liu, Silvia Degli Esposti, Tony Yao, Anna Mae Diehl, Mark A. Zern – 1 November 1995 – Oxidative stress, with reactive oxygen intermediate formation, may represent a common mechanism by which liver injury is induced by diverse etiologies. Oxidative stress enhances nuclear factor kappa B (NF‐κB) activity, and NF‐κB activity has been shown to enhance the expression of cytotoxic cytokines. Acute hepatic injury caused by reactive oxygen intermediate production was induced by an intraperitoneal injection of CCl4 in mice.

Nazzareno Ballatori, Zenaida Gatmaitan, Anh T. Truong – 1 November 1995 – Biliary excretion of methylmercury, a major route of elimination of this toxic compound, was less than 2% of control in Eisai hyperbilirubinemic (EHBR) rats, a mutant Sprague‐Dawley strain with a defect in biliary excretion of a variety of organic anions, including glutathione S‐conjugates and reduced glutathione (GSH). Biliary GSH excretion in EHBR rats was also <2% of controls, confirming previous findings.

Ulrika Broomé, Robert Löfberg, Béla Veress, Ljusk Siw Eriksson – 1 November 1995 – Primary sclerosing cholangitis (PSC) is a biliary destructive disease mostly affecting patients with ulcerative colitis (UC). PSC has been suggested to be an independent risk factor for the development of colorectal malignancy in UC. Patients with PSC also have an increased risk of developing cholangiocarcinoma. This study aimed at assessing the cumulative risk of colorectal neoplasia in PSC and UC, and also to determine risk factors for the development of cholangiocarcinoma.

Nancy L. Ascher – 1 November 1995 – The shortage of liver grafts results in the fact that 8% of potential recipients die before receiving a graft. Liver graft division has therefore been proposed to maximize the current available liver graft pool. However, the question of benefit or additional risk for the recipients that this technique might carry remains unanswered.

Timothy M. McCashland, Teresa L. Wright, Jeremiah P. Donovan, Daniel F. Schafer, Michael F. Sorrell, Thomas G. Heffron, Alan N. Langnas, Ira J. Fox, Byers W. Shaw, Rowen K. Zetterman – 1 November 1995 – Although the incidence of spousal transmission of hepatitis C virus (HCV) in chronic carriers is extremely low (1.4% to 8%), hepatitis C recurrence after liver transplantation is common with markedly increased serum HCV RNA levels. Thus, partners of these patients may be at higher risk of acquiring infection.

Nizar N. Zein, Jorge Rakela, John J. Poterucha, Jeffery L. Steers, Russell H. Wiesner, David H. Persing – 1 November 1995 – Chronic hepatitis C infection (CH‐C) accounts for a significant number of patients undergoing orthotopic liver transplantation (OLT). Recently, hepatitis C virus (HCV) genotype‐dependent differences in disease outcome and therapeutic responses have been suggested.

Steven H. Belle, Katherine M. Detre, Kimberly C. Beringer – 1 November 1995 – For several medical interventions, increasing experience results in improved outcome. This finding may result from better patient selection or increased skill levels. This report examines whether there is a relationship between center experience and patient outcome for liver transplantation, and if so, whether the relationship is explained by patient or donor selection or level of experience required to obtain optimal results.
