Hubertus Wietholtz, Hanns‐Ulrich Marschall, Regina Reuschenbach, Heidrun Matern, Siegfried Matern – 1 April 1991 – Recently the formation of bile acid glucosides has been described as a novel conjugation mechanism in vitro and in vivo. In 10 patients with extrahepatic cholestasis caused by carcinoma of the head of the pancreas we investigated excretion rates and profiles of urinary bile acid glucosides. Urinary bile acid glucosides and, for comparison, bile acid glucuronides were extracted and characterized according to established methods.

Bennie L. Baker, Adrian M. Di Bisceglie, Shuichi Kaneko, Roger Miller, Stephen M. Feinstone, Jeanne G. Waggoner, Jay H. Hoofnagle – 1 April 1991 – Sera from 98 patients with various stages of chronic hepatitis B virus infection were studied to determine the clinical significance of hepatitis B virus DNA in serum detected by the polymerase chain reaction. Patients were divided into three groups according to their HBsAg and HBeAg status.

Jacques Devière, Jean‐Pierre Vaerman, Jean Content, Chantal Denys, Liliane Schandene, Paul Vandenbussche, Yves Sibille, Etienne Dupont – 1 April 1991 – Under endotoxin‐free conditions, peripheral blood mononuclear cells and purified monocytes isolated from healthy control subjects and patients with alcoholic cirrhosis disclose elevated tumor necrosis factor α messenger RNA level and produce tumor necrosis factor α in response to stimulation by either soluble polymeric IgA or monomeric IgA bound to the surface of culture dishes but not by soluble monomeric IgA.

Elisabetta Cariani, Chantal Lasserre, François Kemeny, Dominique Franco, Christian Brechot – 1 April 1991 – Insulin‐like growth factor II is a fetal growth factor structurally and functionally related to insulin and insulin‐like growth factor I. Its mRNA expression is developmentally regulated in human liver, the reexpression of insulin‐like growth factor II fetal transcripts being often observed in primary liver cancer. Insulin‐like growth factor II and α‐fetoprotein mRNAs were studied in 16 human primary liver cancers, most of which were highly differentiated.

Lorenzo Rossaro, Vincenzo Mazzaferro, Carlo L. Scotti‐Foglieni, Donald S. Williams, Elena Simplaceanu, Virgil Simplaceanu, Antonio Francavilla, Thomas E. Starzl, Chien Ho, David H. Van Thiel – 1 April 1991 – The effect of cyclosporin A on the hepatic energy status and intracellular pH of the liver and its response to a fructose challenge has been investigated using in vivo phosphorus‐31 nuclear magnetic resonance spectroscopy in dogs.

Maria Winnock, Marie‐Edith Lafon, Annick Boulard, Anne‐Marie Ferrer, Jean Saric, Liliane Dubuisson, Paulette Bioulac‐Sage, Charles Balabaud – 1 April 1991 – The existence of a marginal lymphocyte population in rat liver sinusoids has already been demonstrated using the sinusoidal lavage method. We used the same technique to study the lymphocyte population in human liver obtained ex vivo after partial hepatectomy for benign or malignant tumors and compared it with peripheral and portal blood lymphocyte populations.

Maria‐Christina Jung, Marietta Stemler, Thomas Weimer, Ulrich Spengler, Jutta Döhrmann, Robert Hoffmann, Dieter Eichenlaub, Josef Eisenburg, Gustav Paumgartner, Gert Riethmüller, Hans Will, Gerd R. Pape – 1 April 1991 – The hepatitis B virus genome encodes a transcriptional transactivator protein designated HBxAg. We have investigated whether this antigen is a target structure for human T‐lymphocytes.
