Permissiveness of kupffer cells for simian immunodeficiency virus (SIV) and morphological changes in the liver of rhesus monkeys at different periods of SIV infection

Yury Persidsky, Anne‐Marie Steffan, Jean‐Louis Gendrault, Bruno Hurtrel, Stefan Berger, Cathy Royer, Hans‐Jochen Stutte, Elizabeth Muchmore, Anne‐Marie Aubertin, André Kirn – 1 May 1995 – The pathogenesis of liver injury, which remains unclear in the course of human immunodeficiency virus infection, can be investigated in simian immunodeficiency virus—infected macaques, which develop an immunodeficiency disease resembling human acquired immune deficiency syndrome (AIDS).

Functional and ultrastructural features of ethanol/bile salts interaction in the isolated perfused rat liver

Domenico Alvaro, Antonio Benedetti, Alessandro Gigliozzi, Adriano Bini, Paola Della Guardia, Tiziana la Rosa, Anne Marie Jezequel, Livio Capocaccia – 1 April 1995 – We investigated whether bile salts (BS) with different hydrophobic‐hydrophilic properties interact with ethanol on bile secretion, enzyme (aspartate transaminase [AST], lactate dehydrogenase [LDH]) release in the perfusate, liver ultrastructure, and vesicular exocytosis in the isolated perfused rat liver.

Induction of metallothionein gene expression by epidermal growth factor and its inhibition by transforming growth factor‐β and dexamethasone in rat hepatocytes

Pierre Moffatt, Gabriel L. Plaa, Francine Denizeau – 1 April 1995 – Metallothionein (MT) is a small cysteine‐rich protein thought to be mainly involved in metal regulation and detoxification. The implication of MT in cell growth and differentiation has also been suggested. This latter hypothesis was further investigated in adult rat hepatocytes induced to proliferate by epidermal growth factor (EGF). Exposure of hepatocytes to EGF resulted in significant increases (≈twofold) in MT protein and MT‐1 messenger RNA (mRNA) levels, which were maximal after 48 hours.

Evidence of preservation injury to bile ducts by bile salts in the pig and its prevention by infusions of hydrophilic bile salts

Martin Hertl, P. Robert C. Harvey, Paul E. Swanson, Delin D. West, Todd K. Howard, Surendra Shenoy, Steven M. Strasberg – 1 April 1995 – Preservation injury to bile ducts is a serious problem in liver transplantation, especially when preservation exceeds 12 hours. The authors hypothesized that the injury was caused by contact of bile ducts with bile salts during cold preservation and might be preventable by infusion of more hydrophilic bile salts.

Structure‐specific inhibition by bile acids of adenosine triphosphate—dependent taurocholate transport in rat canalicular membrane vesicles

Toshirou Nishida, Mingxin Che, Zenaida Gatmaitan, Irwin M. Arias – 1 April 1995 – The adenosine triphosphate (ATP)‐dependent transport system is a major determinant of canalicular bile acid secretion. The system transports bile acids and neither organic cations nor non—bile acid organic anions, such as glucuronides or glutathione adducts. To define the structural specificity of the ATP‐dependent system, the authors examined the ability of various bile acids to inhibit ATP‐dependent taurocholate transport by rat liver canalicular membrane vesicles.

Influence of bezafibrate on hepatic cholesterol metabolism in gallstone patients: Reduced activity of cholesterol 7α‐hydroxylase

Dagny Ståhlberg, Eva Reihnér, Mats Rudling, Lars Berglund, Kurt Einarsson, Bo Angelin – 1 April 1995 – Bezafibrate is a hypolipidemic fibric acid derivative known to induce cholesterol supersaturation of bile. To characterize its effects on hepatic cholesterol metabolism, 31 normolipidemic, normal‐weight patients with gallstones undergoing cholecystectomy were studied. Eleven patients (5 men) were randomized to treatment with bezafibrate, 200 mg three times daily for 4 weeks before operation; the remaining 20 patients (5 men) served as nontreatment controls.

Abnormal expression of the E2 component of the pyruvate dehydrogenase complex on the luminal surface of biliary epithelium occurs before major histocompatibility complex class II and BB1/B7 expression

Koichi Tsuneyama, Judy van de Water, Patrick S. C. Leung, Sanghoon Cha, Yasuni Nakanuma, Marshall Kaplan, Ronald de Lellis, Ross Coppel, Aftab Ansari, M. Eric Gershwin – 1 April 1995 – Primary biliary cirrhosis (PBC) is a chronic autoimmune liver disease characterized histologically by non‐suppurative destructive cholangitis. Sera from patients with PBC react with a series of intramitochondrial enzymes with the immunodominant response directed against the E2 component of the pyruvate dehydrogenase complex (PDC‐E2).

Pretransplantation clinical status and outcome of emergency transplantation for acute liver failure

John Devlin, Julia Wendon, Nigel Heaton, Kai‐Chah Tan, Roger Williams – 1 April 1995 – Emergency transplantation for acute liver failure has a significantly inferior outcome than transplantations performed for elective indications. The severity of the pretransplantation clinical illness in this group will contribute to the reduced patient survival.

Deleterious influence of pyrazinamide on the outcome of patients with fulminant or subfulminant liver failure during antituberculous treatment including isoniazid

François Durand, Jacques Bernuau, Dominique Pessayre, Didier Samuel, Jacques Belaiche, Claude Degott, Henri Bismuth, Jacques Belghiti, Serge Erlinger, Bernard Rueff, Jean Pierre Benhamou – 1 April 1995 – Isoniazid and pyrazinamide are well‐known hepatotoxic drugs, often used in combination. The aim of this study was to assess the prognostic influence of pyrazinamide on the outcome of fulminant or subfulminant liver failure caused by antituberculous therapy. Eighteen patients with fulminant or subfulminant liver failure due to antituberculous therapy were studied.

HLA DPB polymorphism in primary sclerosing cholangitis and primary biliary cirrhosis

James A. Underhill, Peter T. Donaldson, Derek G. Doherty, Koji Manabe, Roger Williams – 1 April 1995 – In recent years there has been an increasing interest in the link between susceptibility to autoimmune liver disease and genes of the HLA system, although the role of the DPB1 locus in British patients has only been investigated in autoimmune hepatitis.
