Michael Manns, Ulrich Zanger, Guido Gerken, Kevin F. Sullivan, Karl‐H. Meyer Zum Büschenfelde, Urs A. Meyer, Michel Eichelbaum – 1 July 1990 – Liver‐kidney microsomal‐1 autoantibodies characterize a subgroup of autoimmune chronic active hepatitis. The liver antigen of liver‐kidney microsomal‐1 antibodies has been identified as cytochrome P450 db1, a microsomal enzyme catalyzing the oxidative metabolism of more than 20 drugs, including debrisoquine, sparteine and bufuralol.

Irene D. Roman, Maria J. Monte, Jose M. Gonzalez‐Buitrago, Alejandro Esteller, Rafael Jiménez – 1 July 1990 – In an attempt to understand the hepatotoxicity associated with immunosuppressive therapy with cyclosporin A, we investigated the effects of acute cyclosporin A administration on biliary secretion, serum bile acid and bilirubin levels and the histological changes in the hepatic parenchyma in anesthetized male Wistar rats.

Kim M. Summers, June W. Halliday, Lawrie W. Powell – 1 July 1990 – The value of measurement of hepatic iron concentration and determination of the hepatic iron index in distinguishing homozygotes from heterozygotes for hemochromatosis was examined. The study group included 42 homozygotes with an unequivocal diagnosis of hemochromatosis and six individuals who had initial equivocal results but were established as homozygous after extensive follow‐up.

Gioacchino Leandro, M. G. Brook, P. Karayiannis, H. C. Thomas – 1 July 1990

Janna Collins, Sidney Goldfischer – 1 July 1990 – A clinicopathologic picture of severe neonatal liver disease associated with heavy stainable iron stores in a “hemochromatotic” distribution has been designated as neonatal or perinatal iron storage disease or hemochromatosis.

William P. J. Leenders, Harrie L. Glansbeek, Wieke C. C. De Bruin, Sing‐Hiem Yap – 1 July 1990 – A likely mechanism of the strong hepatotrophism of the hepatitis B virus is the presence of specific receptors for the surface antigen of hepatitis B virus on hepatocyte membranes. To examine this hypothesis, we have performed binding studies using recombinant large (preS1 + preS2 + S) and major (S) proteins with adult human hepatocytes, rat hepatocytes, human fibroblasts, human peripheral blood mononuclear cells and plasma membranes derived from these cell types.

Ellen B. Hunter, Stephen P. Powers, Louis J. Kost, Delia I. Pinon, Laurence J. Miller, Nicholas F. LaRusso – 1 July 1990 – Although the liver is known to extract amino acids and organic anions by well‐characterized transport systems, the factors that regulate the hepatic uptake of small, circulating peptides are poorly understood. We previously reported that cholecystokinin octapeptide, a biologically active form of cholecystokinin, is efficiently cleared by the liver and that uptake depends on its carboxyl‐terminal tetrapeptide (Trp‐Met‐Asp‐PheNH2).

Subhankar Bandyopadhyay, James E. Klaunig, Pitambar Somani – 1 July 1990 – Hepatocytes from adult male Sprague‐Dawley rats were isolated by the two‐stage collagenase perfusion technique; 1 × 106 cells/plate were incubated in primary cell culture in Leibovitz's L‐15 medium for 24 hr with or without various concentrations (12.5 to 400 μmol/L) of cardioactive cationic amphiphilic compounds such as propranolol, verapamil, sotalol, atenolol and procainamide.

Richard Moreau, Antoine Hadengue, Thierry Soupison, Guy Mechin, Michel Assous, Jacqueline Roche‐Sicot, Christian Sicot – 1 July 1990 – In patients with cirrhosis, vasopressin infusion induces sustained vasoconstriction and elevation of arterial pressure. The vasopressor effect could be caused by impairment of mechanisms normally aimed at buffering increases in arterial pressure (reflex bradycardia and decreases in arteriolar resistance).

Shinzo Kato, Hiromasa Ishii, Sadakazu Aiso, Shuji Yamashita, Daisuke Ito, Masaharu Tsuchiya – 1 July 1990 – The distribution of alcohol dehydrogenase in the hepatic acinus was examined by both histochemical and immunohistochemical approaches. The immunohistochemical method using anti–alcohol dehydrogenase antibody indicated zone 3 predominance of this enzyme in the hepatic acinus, whereas a conventional histochemical method showed slight zone 1 predominance.
