Human hepatoma‐associated cell surface antigen: Identification and characterization by means of monoclonal antibodies

Daniel Shouval, Dan Eilat, Rolf I. Carlson, Ruth Adler, Nelly Livni, Jack R. Wands – 1 May 1985 – A library of murine monoclonal antibodies reactive with human hepatoma cells was generated following immunization of Balb/c mice with an intact cloned human hepatoma cell line, designated PLC/PRF/5‐NR. We report the characterization of one such IgG2a antibody, designated anti‐PLC1.

Histopathological lesions of the liver in hairy cell leukemia: A report of 14 cases

Marie‐Laurence Roquet, Elie‐Serge Zafrani, Jean‐Pierre Farcet, Félix Reyes, Yvon Pinaudeau – 1 May 1985 – Pathological lesions of the liver were studied in 14 cases of hairy cell leukemia, a rare hematologic neoplasm involving numerous organs. Tumor infiltration of hepatic parenchyma was observed in all cases. Tumor cells were easily recognized by their cytological features, namely their “halo” appearance consisting of a clear rim of abundant cytoplasm surrounding uniform round or slightly indented nuclei.

Immunofluorescent determination of the lobular distribution of a constitutive form of hepatic microsomal cytochrome P‐450

David E. Moody, Lorna A. Taylor, Edward A. Smuckler – 1 May 1985 – We have used an immunohistochemical approach to study the lobular distribution of constitutive liver microsomal cytochrome P‐450. Cytochrome P‐450 isolated (10.3 nmoles per mg protein) from hepatic microsomes from untreated, mature male Sprague‐Dawley rats was used to produce antisera in rabbits.

The immunologic diagnosis of chronic active “autoimmune” hepatitis: Distinction from systemic lupus erythematosus

Lawrence E. Gurian, Thomas M. Rogoff, Athol J. Ware, Robert E. Jordan, Burton Combes, James N. Gilliam – 1 May 1985 – We have evaluated the immunologic characteristics often associated with systemic lupus erythematosus in a series of patients with a variety of different liver diseases. Antibody to doublestranded DNA as measured by the Farr assay was detected frequently in patients with various forms of liver disease. No patient with liver disease, including those with a presumed immunologic etiology, was found to have antibody to double‐stranded DNA using more specific assays.

Synthesis of heat shock proteins in rat liver after ischemia and hyperthermia

Gaetano Cairo, Lidia Bardella, Luisa Schiaffonati, Aldo Bernelli‐Zazzera – 1 May 1985 – Ischemia of rat liver is followed by recovery or cell death. Since heat shock proteins may be essential to cell survival under stress, we determined levels of heat shock proteins in liver after different periods of blood deprivation and correlated the results with cellular recovery. Cell‐free synthesis by poly (A+)‐mRNA and polysomes revealed 70 and 89 kd proteins which appear similar to proteins produced by the liver of rats with amphetamine‐induced hyperthermia.

Age‐related changes in the endocytic capacity of rat liver kupffer and endothelial cells

Adriaan Brouwer, Roel J. Barelds, Dick L. Knook – 1 May 1985 – There are many indications that the functional capacity of the reticuloendothelial system (RES) declines with age. The aim of this study was to investigate the cellular basis of age‐related changes in the clearance function of the RES. The experiments were focused mainly on Kupffer and endothelial cells of the liver which represent a major part of the RES and are primarily responsible for clearance of colloidal material from the circulation.

Presinusoidal portal hypertension in non‐alcoholic cirrhosis

Gilles Pomier‐Layrargues, Daniel Kusielewicz, Bernard Willems, Jean‐Pierre Villeneuve, Denis Marleau, Jean Cǒté, P.‐Michel Huet – 1 May 1985 – The simultaneous measurement of wedged hepatic vein pressure (WHVP) and portal vein pressure (PVP) was performed in 156 cirrhotic patients. In the 110 alcoholic cirrhotic patients (97 micronodular and 13 macronodular cirrhosis), WHVP and PVP were closely related (25.8 ± 6.3 vs. 25.9 ± 6.3 mm Hg; p = not statistically significant). The difference between the two parameters was greater than 4 mm Hg in only six patients.
