Jiřina Martínková, Josef Bulas, Vladimír Krejčí, Miroslav Hartman, Ivan Tilšer, Petr Hůlek – 1 November 1990 – We have studied the action of a series of vasoactive and antispasmodic agents on the intrahepatic vasoconstriction induced by adrenaline in the isolated perfused liver of rabbits. The arterial and portal venous resistance, oxygen consumption, liver weight and bile flow were investigated.

Yao Zhiqiang, Yang Weisong, Zhang Wenbin, Chen Yong, Yang Fengyi – 1 November 1990 – Current support or replacement therapies for fulminant acute hepatic failure are frequently very disappointing. In this study, human hepatic stimulator substance—a liver‐specific growth factor—was partially purified from human fetal liver cells and characterized by its biological effects. Almost 70‐fold protein content was purified with an approximately 80‐fold increase in specific growth stimulator activity.

Linda J. Scully, David Brown, Chris Lloyd, Ruvan Shein, Howard C. Thomas – 1 November 1990 – Lymphoblastoid interferon is effective therapy in some but not all patients with chronic hepatitis B virus infection. To assess whether immunological parameters were predictive of response to interferon therapy, we determined the human leukocyte antigen type, CD4/CD8 ratio, natural killer cell activity, IgM anti‐HBc antibody levels and concanavalin A—induced lymphocyte proliferative response in 30 patients before treatment.

Kai O. Lindros, Yuan Cai, Kai E. Penttilä – 1 November 1990 – The ethanol‐inducible form of cytochrome P‐450 (IIE1) is expressed and induced by ethanol, predominantly in the centrilobular region. Because this isoenzyme has a particularly high capacity to convert carbon tetrachloride and several other hepatotoxins into reactive intermediates, its role in producing damage was studied by comparing the effect of carbon tetrachloride exposure on hepatocytes isolated from either the periportal or the perivenous region by digitonin‐collagenase perfusion.

Cihan Yurdaydin, Heide Hörtnagl, Petra Steindl, Christof Zimmermann, Christian Pifl, Ernst A. Singer, Erich Roth, Peter Ferenci – 1 October 1990 – Functional changes of various neurotransmitter systems have been implicated in the pathogenesis of hepatic encephalopathy. In this study the role of brain monoaminergic neurotransmitter systems in hepatic encephalopathy was investigated in rats with thioacetamide‐induced acute liver failure.

Fergus D. Davison, Elizabeth A. Fagan, Bernard Portmann, Roger Williams – 1 October 1990 – One patient with the fibrolamellar variant of hepatocellular carcinoma was found to be seropositive for HBsAg and anti‐HBe. DNA from tumor and nontumor areas of the liver was examined by molecular hybridization for hepatitis B virus DNA sequences. Undigested DNA from the tumor gave a high‐molecular‐weight smear, and restriction‐enzyme analysis indicated a single instance of integration. Nontumor liver tissue was analyzed from three separate areas.

Wouter H. Lamers, Willem Been, Robert Charles, Antoon F. M. Moorman – 1 October 1990 – Urea cycle enzymes and glutamine synthetase are essential for NH3 detoxification and systemic pH homeostasis in mammals. Carbamoylphosphate synthetase, the first and flux‐determining enzyme of the cycle, is found only in a large periportal compartment, and glutamine synthetase is found only in a small, complementary pericentral compartment.
