Paloma Maganto, Peter G. Traber, Christopher Rusnell, William O. Dobbins Iii, David Keren, Jorge J. Gumucio – 1 April 1990 – Hepatocytes isolated from livers of Fischer 344 rats and transplanted into the spleens of rats from the same strain survived for at least 15 mo in the absence of immunosuppressive drugs. Hepatocytes attached themselves only in the red pulp of the spleen, most commonly in clumps without a discernible structure.

Marios Z. Panos, Kevin Moore, Panayiotis Vlavianos, John B. Chambers, John V. Anderson, Alexander E. S. Gimson, Jeremy D. H. Slater, Lesley H. Rees, David Westaby, Roger Williams – 1 April 1990 – Hemodynamic changes induced by a single, total paracentesis were evaluated in 21 patients with tense ascites from whom 4 to 16 L of ascites were drained over 2 to 8 hr with no serious complications.

Salvatore Badalamenti, Pere Gines, Vicente Arroyo, Josep Llach, Carlos Piera, Antoni Rimola, Wladimiro Jimenez, Joan Gaya, Roser Casamitjana, Francisca Rivera, Joan Rodes – 1 March 1990 – Acute intravenous amino acid infusion or a highprotein diet increases renal plasma flow and the glomerular filtration rate in healthy subjects. Conversely, a low‐protein diet reduces renal plasma flow and glomerular filtration rate. The aim of this study was to investigate the effect of intravenous amino acid infusion and dietary proteins on kidney function in cirrhosis.

Hidefumi Higashi, Katsuhiko Yanaga, J. Wallis Marsh, Andreas Tzakis, Saduro Kakizoe, Thomas E. Starzi – 1 March 1990 – Between February 26, 1981, and July 30, 1987, 36 patients underwent orthotopic liver transplantation for primary sclerosing cholangitis associated with ulcerative colitis. Three of the 36 recipients died within 3 mo because of graft nonfunction or surgical complications. The other 33 (92%) lived for at least 1 yr. Two of the 33 died after 12 and 14 mo, respectively, of recurrent cholangiocarcinoma that was not diagnosed before transplantation.

Flemming Bendtsen, Lene Theil Skovgaard, Thorkild I. A. Sørensen, Peter Matzen – 1 March 1990 – The interobserver variation in diagnosis and grading of esophageal varices may be ascribed by characteristics of the observers as well as to the patients. Assessment of this variation therefore requires the contributions of multiple observers and patients. Twenty‐eight patients with cirrhosis without previous bleeding or known presence of varices were subjected to upper gastrointestinal endoscopy. Each endoscopy was videotaped and shown to 22 endoscopists.

David Westaby, Rex J. Polson, Alexander E. S. Gimson, Peter C. Hayes, Karen Hayllar, Roger Williams – 1 March 1990 – This trial was carried out to assess the value of propranolo for the prevtion of recurrent variceal bleeding in patinets with well‐compensated cirrhosis. We also compared porpranolol therapy to long‐term injection sclerotherapy. One hundred and eight patients, in whom the orginal variceal hemorrhage stopped spontaneousley (before diagnostic endocopy) and without sclerotherpay or surgical intervention were included. All were pugh grade A or B; 55% had alcoholic cirrohosis.

Renee C. Lin, Michael J. Fillenwarth, Ronald Minter, Lawrence Lumeng – 1 March 1990 – We have previously reported that a 37‐kD liver protein formed an adduct with acetaldehyde in vivo when rats were fed alcohol chronically. To understand the mechanism of the formation of this proteinacta ldehyde adduct, rat hepatocytes in primary culture were treated with ethanol in vitro for several days. When cultured in hormone‐enriched and trac metalenriched Waymouth's medium, alcohol dehydrogenase activities in hepatocytes decreased only about 30% during 6 days of culture.

Raf Sciot, Guido Verhoeven, Peter van Eyken, Jean Cailleau, Valeer J. Desmet – 1 March 1990 – Hepatic transferrin receptors were studied in normal male rats at 1 to 59 wk after weaning, using immunohistochemical and biochemical techniques. The number of transferrin receptors measured and the intensity of the staining in situ decreased rapidly during the first 10 wk of life and more slowly thereafter. Immunohisto‐chemistry further demonstrated changes in the topographical and (sub)cellular localization of the transferrin receptor.

Hiromu Kawahara, Monique Cadrin, George Perry, Lucila Autilio‐Gambetti, Sabine H. H. Swierenga, Janis Metuzals, Normand Marceau, Samuel W. French – 1 March 1990 – The role of cytokeratin filaments in the function of hepatocytes was investigated using a nickel‐treated hepatocyte in vitro model. Cytokeratin intermediate filaments were selectively dissociated from the cell cortex by nickel treatment. Cytokeratins and ubiquitin were observed using immunofluorescence and immunoelectrom microscopy.
