The human hepatic asialoglycoprotein receptor is a target antigen for liver‐infiltrating T cells in autoimmune chronic active hepatitis and primary biliary cirrhosis

Hanns Löhr, Ulrich Treichel, Thomas Poralla, Michael Manns, Karl‐Hermann Meyer Zum Büschenfelde, Bernhard Fleischer – 1 December 1990 – Autoantibodies to the human hepatic asialoglycoprotein receptor have been found in nearly 50% of the sera of patients with autoimmune chronic active hepatitis and in 15% of patients with primary biliary cirrhosis. In this study we demonstrate that the human hepatic asialoglycoprotein receptor is also a target antigen for T cell—mediated immune responses.

Hepatitis C virus antibodies in chronic alcoholic patients: Association with severity of liver injury

Albert Parés, Josep María Barrera, Joan Caballería, Guadalupe Ercilla, Miquel Bruguera, Llorenç Caballería, Ricardo Castillo, Joan Rodés – 1 December 1990 – The prevalence of hepatitis C virus antibody and its relationship to the severity of liver disease in chronic alcoholic patients has been assessed, using a recently developed enzyme immunoassay and confirmed by a recombinant immunoblot assay, in 144 patients (mean age ± S.D. = 44.4 ± 11.3 yr) who had consumed >80 gm/day ethanol for >5 yr.

Characterization and accumulation of ferritin in hepatocyte nuclei of mice with iron overload

Andrew G. Smith, Philip Carthew, Jean E. Francis, Richard E. Edwards, David Dinsdale – 1 December 1990 – After a single subcutaneous dose of iron‐dextran (600 mg of iron/kg), iron overload developed in C57BL/10ScSn mice. At 4, 24 and 78 wk liver nonheme iron concentrations were 67‐, 42‐ and 21‐fold higher than controls, respectively. Much of the iron was in macrophages, but hepatocytes were also strongly positive for Perls' stainable iron. One feature was the development of iron‐positive nuclear inclusions in hepatocytes.

Differential regulation of liver P‐450III cytochromes in choline‐deficient rats: Implications for the erythromycin breath test as a parameter of liver function

Joseph C. Kolars, Scott A. Murray, Ken M. Peters, Paul B. Watkins – 1 December 1990 – Progressive liver fibrosis in rats develops when they are fed a diet deficient in choline. This diet also results in a pronounced and selective decrease in the liver microsomal content of a phase I drug—metabolizing enzyme belonging to the cytochrome P‐450III gene family. Because P‐450III cytochromes characteristically catalyze the N‐demethylation of erythromycin, we believed that the production of breath CO2 from erythromycin would be dramatically reduced in choline‐deficient rats.

Early and frequent detection of HBxAg and/or anti‐HBx in hepatitis B virus infection

Ludmila Vitvitski‐Trépo, Alan Kay, Christian Pichoud, Philippe Chevallier, Stéphane de Dinechin, Blanche‐Marie Shamoon, Elisabeth Mandart, Christian Trépo, Francis Galibert – 1 December 1990 – To clarify the significance of the X gene of hepatitis B virus, we have tested for anti‐HBx in the serum and HBxAg in the liver at different stages of the natural history of hepatitis B virus infection. Sera were screened by enzyme‐linked immunosorbent assay and positive results confirmed by immunoblot. Purified recombinant MS2 Pol‐HBx fusion protein was used as target for both assays.

Mechanism for binding of fatty acids to hepatocyte plasma membranes: Different interpretation

Judith Storch – 1 December 1990 – The purpose of this study was to examine the interaction between fatty acids and plasma membranes from liver cells. We were unable to reproduce the reported effect of heating on the capacity of these membranes to bind [3H]oleate (Stremmel et al. Proc Natl Acad Sci USA, 1985;82:4–8). In fact, the distribution of [3H]oleate between plasma membranes and unilamellar vesicles of lipids extracted from these membranes was in favor of the lipids, indicating the absence of a detectable amount of binding to a putative fatty acid binding protein in plasma membranes.

Normalization of ventilation/perfusion relationships after liver transplantation in patients with decompensated cirrhosis: Evidence for a hepatopulmonary syndrome

Ljusk Siw Eriksson, Charlotte Söderman, Bo‐Göran Ericzon, Lennart Eleborg, John Wahren, Göran Hedenstierna – 1 December 1990 – To examine the effect of liver transplantation on the respiratory and cardiovascular functions, ventilation/perfusion relationships were determined by multiple inert gas elimination technique in six patients with end‐stage liver disease 1 to 19 mo before and 2 to 6 mo after liver transplantation. Cardiac output and pulmonary vascular pressures were measured after catheterization of the pulmonary artery.
