Hans P. Dienes, Georg Hess, Marita Wöorsdörfer, Siegbert Rossol, Harald Gallati, Giuliano Ramadori, Karl‐Hermann Meyer Zum Büschenfelde – 1 February 1991 – Cells expressing α‐ and γ‐interferon were localized in the liver tissue of patients with chronic hepatitis B by means of light and electron microscopy using monoclonal antibodies. Interferon‐positive cells were regularly seen in the infiltrating mononuclear cells, and the number showed a good correlation with the degree of the necroinflammatory activity of the disease.

Pierre‐Yves Rescan, Bruno Clement, Yoshihiko Yamada, Denise Glaise, Bartolome Segui‐Real, Christiane Guguen‐Guillouzo, André Guillouzo – 1 February 1991 – Dramatic cellular changes that occur during hepatocarcinogenesis are associated with major alterations in extracellular matrix formation and in the relationships between cells and their microenvironment.

Grete M. Kindberg, Helge Tolleshaug, Tor Gjøen, Trond Berg – 1 February 1991 – Air‐filled albumin microspheres, asialoorosomucoid and formaldehyde‐treated serum albumin are selectively taken up by endocytosis in rat liver Kupffer cells, parenchymal cells and endothelial cells, respectively. Intracellular transport and degradation of endocytosed material were studied by subcellular fractionation in sucrose and Nycodenz gradients after intravenous injection of the ligand.

Paul B. Watkins – 1 February 1991 – Patients with dihydralazine hepatotoxicity have been found to have circulating autoantibodies that react with liver microsomes (anti‐liver microsome antibodies) and that are clearly distinct from anti‐liver and kidney microsomal antibodies observed in patients with tienilic acid‐induced hepatitis and in some patients with autoimmune hepatitis. The authors show that anti‐liver microsome antibodies present in the sera of five patients with dihydralazine‐induced hepatitis specifically react on immunoblots with a 53 kD protein.

Kunjo Okuda, Shujiro Sugita, Etsuo Tsukada, Yoichi Sakuma, Keishi Ohkubo – 1 February 1991 – The ultrasound and computed tomographic imaging features in a rare pancreatic pseudocyst of the liver are described in two patients. The pseudocysts occurred in the left lobe in both cases, one after a traumatic injury and the other after alcoholic pancreatitis. The possible topographical sequences with which pancreatic secretions entered the left hepatic lobe to form a cyst are discussed. (HEPATOLOGY 1991;13:359–363).

Marcello Persico, Marco Romano, Maurizio Muraca – 1 February 1991 – We present the case of a 23‐yr‐old man who had had since birth marked and sustained unconjugated nonhemolytic hyperbilirubinemia and who had had several attacks of grand mal seizures. Analysis of serum bilirubin by diazoreactive methods showed serum levels of unconjugated bilirubin as high as 445 μmol/L that were not affected by phenobarbital administration.

Kazuo Tanoue, Seigo Kitano, Makoto Hashizume, Hiroya Wada, Keizo Sugimachi – 1 February 1991 – We have developed a new method for inducing portal hypertension and esophageal varices in rats—partial ligation of the portal vein after devascularization of the circumference of the left renal vein and complete ligation of the portal vein on the fifth day thereafter. Thirty rats were separated into groups of 10, control (sham operation), complete portal ligation only and complete portal ligation plus devascularization.
