Possible multicentric occurrence of hepatocellular carcinoma: A clinicopathological study

Kenji Takenaka, Eisuke Adachi, Takashi Nishizaki, Kaichiro Hiroshige, Toshihiko Ikeda, Masazumi Tsuneyoshi, Keizo Sugimachi – 1 April 1994 – To assess the features of multicentric occurrence in hepatocellular carcinoma, we analyzed 10 of 72 patients (14%) who had undergone hepatic resection for hepatocellular carcinoma from May 1989 to October 1992 both clinically and pathologically.

Intrasplenic transplantation of isolated periportal and perivenous hepatocytes as a long‐term system for study of liver‐specific gene expression

Ling Chen, Gerard J. Davis, David W. Crabb, Lawrence Lumeng – 1 April 1994 – Many hepatocyte‐specific genes are expressed heterogeneously in the liver lobule depending on the location of the hepatocytes in relation to the inflow or outflow of portal blood (i.e., periportal or perivenous). For example, albumin is expressed in all hepatocytes but more so in the periportal zone, cytochrome P‐450IIE1 is exclusively expressed in the perivenous zone and glutamine synthetase is limited to one or two cell layers next to the terminal hepatic venule.

Stimulation of phagocytic activity of murine Kupffer cells by tuftsin

Shoji Kubo, Tom Rodriguez, Mark S. Roh, Caroline Oyedeji, Marvin M. Romsdahl, Kenji Nishioka – 1 April 1994 – Tuftsin (Thr‐Lys‐Pro‐Arg) is a natural immunomodulating peptide. We have investigated for the presence of a specific tuftsin receptor on murine Kupffer cells using fluorescein‐labeled tuftsin, which retains full biological activity. After incubation with fluorescein‐labeled tuftsin, Kupffer cells displayed clear binding of this compound on the plasma membrane. Excess tuftsin inhibited this binding, indicating the presence of specific tuftsin receptors on the Kupffer cells.

Hold that needle: Octreotide for acute variceal hemorrhage

William N. Katkov – 1 April 1994 – To compare octreotide with injection sclerotherapy in the treatment of acute variceal hemorrhage, patients admitted with gastrointestinal bleeding and oesophageal varices confirmed by endoscopy were randomised to receive either emergency sclerotherapy with 3% sodium tetradecyl sulphate or octreotide (50 μg intravenous bolus plus 50 μg per hr intravenous infusion for 48 hr). At the end of the study period (48 hr), the octreotide group also had sclerotherapy to obliterate the varices.

Strong transient expression of the type I interferon–induced MxA protein in hepatitis A but not in acute hepatitis B and C

Detlef Jakschies, Reinhardt Zachoval, Rainer Müller, Michael Manns, Klaus‐Ulrich Nolte, Heinz‐Kurt Hochkeppel, Michel‐Andre Horisberger, Helmuth Deicher, Peter Von Wussow – 1 April 1994 – The human MxA protein is a new specific marker for type I interferon activity both in vitro and in vivo.

Fibrinogen assembly: Insights from chicken hepatocytes

Carole Oddoux, Gerd Grieninger – 1 March 1994 – In all vertebrate species studied, the complex, disulfide‐linked structure of fibrinogen is essentially the same: a hexamer assembled from three different subunits (Aα, Bß,γ)2. This study utilized species differences in fibrinogen subunit monomer pools to address the question of how these surplus subunit pools may affect the assembly process. We used a chicken model system in which Bß and γ‐subunits are present in excess, in contrast to the Aα and γ‐subunit surplus found in human model systems.

Enhanced hepatic collagen type I mRNA expression into fat‐storing cells in a rodent model of hemochromatosis

Antonello Pietrangelo, Rossana Gualdi, Giovanna Casalgrandi, Albert Geerts, Pieter de Bleser, Giuliana Montosi, Ezio Ventura – 1 March 1994 – In recent years, identifying the hepatic cell type responsible for collagen synthesis in experimental models of postnecrotic or inflammatory fibrosis has been the subject of active investigation. In primary iron overload states, however, hepatic fibrosis and cirrhosis occur without accompanying necroinflammatory phenomena.
