P Portincasa, K J van Erpecum, A Jansen, W Renooij, M Gadellaa, G P van Berge‐Henegouwen – 1 April 1996 – Besides classical plate‐like cholesterol monohydrate crystals, a variety of crystal shapes have recently been described in model biles but their relevance for human gallstone formation is unknown. We therefore studied crystallization behavior in gallbladder bile from cholesterol stone patients (54 untreated, 13 ursodeoxycholate‐treated) and 6 pigment stone patients.

J G Wagner, P E Ganey, R A Roth – 1 April 1996 – Polymorphonuclear leukocytes (PMNS) have been implicated as cellular mediators of hepatic injury in models of inflammation in vivo. In vitro, hepatocyte killing by activated PMNs is mediated in part by proteases, but the role of nitric oxide is unknown. NO is produced by PMNs and hepatocytes and can act either to damage or protect in various models of toxicity. Therefore, we tested the hypothesis that NO is important in PMN‐mediated hepatocyte killing in vitro.

K Sone, M Maeda, K Wakabayashi, N Takeichi, M Mori, T Sugimura, M Nagao – 1 April 1996 – Trientine dihydrochloride (trientine) is an alternative medicinal copper chelating agent for patients with Wilson's disease of penicillamine intolerance. We examined the effects of trientine on the spontaneous development of hepatitis and hepatic tumors, by its short‐ term and long‐term administration to Long‐Evans cinnamon (LEC) rats with an accumulation of copper in the liver, as animal models of Wilson's disease.

G V Gregorio, P Jara, L Hierro, C Diaz, A de la Vega, A Vegnente, R Iorio, F Bortolotti, C Crivellaro, L Zancan, H Daniels, B Portmann, G Mieli‐Vergani – 1 April 1996 – The comparative efficacy of prednisolone followed by interferon alfa (IFN‐α) versus IFN‐α alone in enhancing the rate of antibody to hepatitis B e antigen (anti‐HBe) seroconversion has not been evaluated in a large cohort of white children.

P H McGuinness, G A Bishop, D M Painter, R Chan, G W McCaughan – 1 April 1996 – The balance between a direct cytopathic effect by hepatitis C virus (HCV) and immune‐mediated injury remains unclear. This report aims to test the following hypotheses: (1) that intrahepatic HCV load would correlate with the degree of liver injury; (2) that interferon alfa (IFN‐α) would decrease intrahepatic HCV‐RNA levels. Liver tissues (n = 56) were obtained from 47 patients with chronic HCV (9 before and after IFN‐α therapy).

P K Yuet, D Blankschtein, J M Donovan – 1 April 1996 – To accurately determine the cholesterol (Ch) distribution between mixed micelles and vesicles in lithogenic bile, both ultracentrifugation and gel chromatography with the correct intermixed micellar/vesicular bile salt concentration (IMC) have been proposed. We have systematically compared both separation techniques with physiological model biles to ascertain their quantitative separation ability.

Norah A. Terrault, Connie Combs Holland, Linda Ferrell, Judith A. Hahn, John R. Lake, John P. Roberts, Nancy L. Ascher, Teresa L. Wright – 1 March 1996 – Reinfection with hepatitis B virus (HBV) after liver transplantation is nearly universal in patients not receiving immunoprophylaxis. Because reinfection reduces graft and patient survival, treatment of recurrent infection is important. Interferon alfa (IFN‐α) is an effective therapy for chronic hepatitis B infection in immunocompetent patients, but its efficacy in transplant recipients has not been established.

Christine M. Hunt, Julie S. Tart, Elaine Dowdy, Barbara Philips Bute, Diane M. Williams, Pierre‐Alain Clavien – 1 March 1996 – Employment, functional status, health status, and prevalence of anxiety and depression were assessed in patients who had undergone orthotopic liver transplantation at Duke University from 1984 to 1993 to identify social and economic factors that might influence return to work after liver transplantation. Patients were asked to complete mailed questionnaires. A transplant nurse coordinator assigned patients a Karnofsky score, unaware of the questionnaire responses.

Jean C. Emond, Scott D. Kelley, Thomas G. Heffron, Tomonori Nakagawa, John P. Roberts, Robert C. Lim – 1 March 1996 – Total vascular exclusion (TVE) of the liver is accomplished by complete occlusion of inflow and outflow of the liver during hepatectomy. It affords the opportunity for bloodless, anatomically precise parenchymal transection but has not been widely used in this country. TVE should make it possible to treat large or unfavorably located lesions safely. To evaluate the benefit of this modality, we have examined the results of TVE in 49 major resections.
